Woodworking Tools

We Tried it - Ridgid Tablesaw TS2410LS

  The Ridgid TS2410LS  is sound looking contractor style table saw. Although as woodworkers, don't give tool "looks" a lot of credibility, still if a tool looks sturdy it makes one want to at least try it out, which we did. Overall the saw appeared well manufactured with quality materials and nicely finished components, the first signs that you may be dealing with a quality item. At first blush, the saw seemed to have all controls easily available for the operator and everything ran smoothly. Click below to read more about what we found using this saw ...

The saw is equipped with a solid table, this is good for sturdiness. The one thing we really liked was the built-in "TSUV™ Table Saw Utility Vehicle" folding base. The base has special bracket that lets you quickly turn the saw's base into a hand trolley of sort. This makes the saw easy to move and solid to work with, a REAL bonus for so many woodworkers who have limited space and need mobility bases. The hand trolley not only lets you move the saw around, but also has room to carry wood and other items at the bottom ... saves making two trips. Many other mobile bases are unstable, use only tiny wheels, or use locking wheels, all in all my experience with this is not great, mostly because few are really solid once they are supposed to be ready for use; a real safety hazard.

Ridgid Tablesaw TS2410LS

The controls on the Ridgid were smooth and easy to use, but one would expect smooth on a new tool. One of the most important purposes of a table saw is ripping wood, and having a good rip fence is a must. We found the rip fence on the ridgid OK, not fabulous, just OK. This is not a bad thing for a contractors saw. There is a micro adjustment, which is also OK. Moving the fence back and forth was nice and smooth and when it was locked in place it was solid! We found the fence was not too hard to adjust as it was slightly out of alignment from the factory. The other thing we liked about the rip fence and the saw: a very decent extension, like 26 inches to the right of the blade and 12 to the left of the blade.

The next thing we looked for was the alignment of the blade to the mitre slots. Most woodworkers don't realize that the under carriage of the blade is adjustable and should be adjusted so that the blades are perfectly aligned with the mitre slots. This is where perfectly, non-binding ripped wood comes from. To our delight, there was NO adjustments needed to the trunion assembly, it was off slightly, but was well within the tolerances of working with wood.

The next thing was to try some ripping and crosscutting. To be honest, there is little value in testing a tablesaw unless you use a "known table saw blade". The blade that comes with the Ridgid looked OK, but we opted to use our tried-and-true Freud "Glueline Rip, 60 tooth crosscut and combination blades because we know what they produce. After installing the Freud Glueline rip and turning on the saw, we were very impressed with the smooth, very low vibration and overall "tightness" of the saw. Part of this we deemed was the extra attention Ridgid paid to the pulley and special multi-band belt that connects the motor to the saw blade. An excellent choice for smooth operation.

The first wood we ran through the saw was three quarter inch red oak. The saw, with it's 15 Amp motor ate breezed through it no problem. We decided to try some two inch beech just to see what that would do, and this was getting to be a bit much for this saw's horsepower, although it made it through with a bit of reluctance , but then we knew this was pushing this saw beyond it's purposes. We went on to try the crosscut and combination blades with a variety of woods and found the saw a real joy to use.

If we have any fault with the saw , or really with the accessories, like most saws in this category the mitre gauges are only OK. If you want or need good cross cutting with your table saw a sled or one of the aftermarket mitre gauges would be a good choice.

All in all we really liked this saw, it was smooth, easy to use and very nice for anyone with a smaller work space. If you really want a quality saw this would be a good choice and one day if you have a few extra buck, purchase a bit beefier motor and this saw will be lifetime keeper.

We Tried it - Drill Doctor Drill Bit Sharpener Review

We have seen these handy drill sharpening devices advertised in magazines for a few years now and have always wondered how well they work. As a strong advocate of sharp tools I never really seem to know when my drill bits are getting dull except when I'm in the middle of a job and need a sharp bit the most. I have inexpensive bits and I have good drill bits and believe me, there is a big difference, but I will go into that in another article. The only bits I use are the good bits and although they stay sharp longer, they still get dull ... click below to read HOW drill bits get dull and what to do about it.

First of all, drill bits don't necessarily get dull because you are drilling into hard steel or rock or concrete. Drill bits can dull very easily drilling into nothing but wood. The reason drill bits get dull is because most of them are just steel and when steel gets hot it melts. Know I know your drill bits don't "melt" ... but the very tips of the edges can get hot enough to begin to melt which means that the steel fatigues and the edge is then lost. If you don't believe me, imagine! making about 20 deep holes into some 2" oak then try touch your drill bit with your bare fingers .... yeah! ... It's hot enough to leave third degree burns. And so what happens, the edge is now gone on your drill bit, what to do now.

Enter the Drill Doctor. We were impressed with the package. The Drill Doctor - "The Drill Bit Sharpener" unit comes in a nice blue plastic container, well laid out and with instructions and a video that were easy to follow but not extensive (which is what we hoped for). It was nice to see that it all went back fairly easily into the case when we were done too - something a lot of OTHER VENDERS could learn from -hint, hint.

The Drill Doctor we tried out comes with a couple of special "jigs" that you must first load your dull drill bit into. Depending on the size of the bit you select either to larger or the smaller jig. Not difficult to do, but it does need to be aligned as your instructions indicate.

We decided to really work this unit by sharpening a large bit. We thought that doing a small bit would not be to trying on the machine and we really needed to give it a good workout so we started off with a pretty wicked looking 3/8" bit. In fact, I would venture a guess to say this bit could have been used as a punch at some time in it's life, it certainly hadn't drilled any holes for some time.

As we inserted the bit and jig into the Drill Doctor and it switched on we could hear the small electric motor inside spinning up speed. The trick with these units is that you have to twist the bits in their jig as you insert and press it against the internal grinding wheel.

We expected that if the Drill Doctor could re-grind our bit it would take a while ... and it did, but in the end it did a pretty nice job. We did find that using the unit was a little bit slow on larger bits and it takes a while to get used to using, but it did fix up our rack of dull bits. In fact I might even say some or all seemed to be even sharper that when they were new ... this may not be the case but they seemed to be at least as sharp as they were when they were new.

So, if you want to breath new life into your steel twist drill bits, Drill Doctor does a nice job, but be patient with the larger bits, they take longer and may need a bit more attention. Now if only they could come up with something that will do my brad point bits, that would really make me happy.

The Radial Arm Saw

  Sometimes the best deals in tools can be made by looking to the past. In the decade when "sliding compound" and "chop" saws are the norm, why would anyone even want to consider a Radial Arm Saw ? I must admit I haven't had much to do with Radial Arm Saws for years, and like many others, had purchased a sliding compound saw. I never was in love with the sliding compound. I found it a bit light-weight and ... well, a bit finictity to use, if you know what I mean.

Recently I inherited at barely operational Radial Arm Saw . It hadn't been used in years and needed a real big clean-up. I decided rather than throw it out, I would re-build this saw from the past and try putting it to work. Lucky for me the motor worked, and pretty much everything else on the saw except the power switch, which was the first repair. All saws movements were either seized or very stiff ... so after a few hours of dis-assemble and re-assembly with bit of new grease and oil ... everything worked like new again.

One of the problems with these ole Radial Arm Saws is that they can be more dangerous than some other saws. Most of the reason for this is because they seldom are fitted with the right blade, which makes all the difference to this saw .... click below to read more

Often these saws came from the manufacturer with horrible old combination blades with teeth in them that looked like they could rip through two inches of solid steel. These old blades are part of the "safety" problem with Radial Arm Saws. If you have one of these blades, I suggest you make an nice shop clock from it or send it to metal scrap, do not use these blades on anything, unless you are cutting fire wood. Their cut is rough and they are far too aggressive for most woodworking applications.

I have found the one of the best blades is the 72 tooth Freud Sliding Coupound cross cut blade , and if you want to add another element of safety, you could pick up the one with the anti-kickback teeth. These 72 tooth blades give excellent cuts and are far less dangerous and aggressive than the old "combo blades" that came with these saws. This particular blade was designed for chop and sliding chop saws and is manufactured with a NEGATIVE tooth hook angle. This means that the blade is biting more into the wood surface and using the table for resistance than postive hook angle teeth that would be biting into the back of the wood being cut where the resistance is more the person holding the wood (and subsequently more dangerous).

Most of the Radial Arm Saws are pretty easy to figure out, even if you have never operated one before. They also do some hand things that a Sliding Compound could never do, like rip wood or use a Dado blade in for certain applications. I particularly like the ease with which 45 degree cuts can be made, and they are accurate, at least on my saw they are ... which is more that I could say for the sliding compound which could never seem to make a decent 45 degree cut.

The disadvantage of these saw is that they are not portable ... at all, despite that in the past they were used on construction sites and were even advertised as construction site saws, these things are big and heavy, and I would venture a guess to say if saw safety were an issue, moving these saws is far more dangerous than actually operating them.

In terms of saw guards and saw dust collection, Radial Arms Saws also have draw backs. The dust collection, although not usually a big issue with cross cutting, is often not well handled by most of these saws although many do at least come with at shute to attach a hose to. These saw never did experience good quality saw guards. That is one area the more recent Sliding Compound and Chop saws have it over the old Radial Arm Saws. But - With careful and deliberate operation and the proper blades these old gems from the past can still be very useful tools.

If you really want to dress up your saw and make VERY usefull, adding a Flip Top fence stop is a HUGE time saver. I have discovered that after a few weeks of use I have fallen back in love with this "vintage saw". I like how sturdy and secure it feels and how it handles cutting. The tool is far more versatile than any Sliding Compound, and the best part is ... you can pick up these tools right now for next to nothing. Just check out your local auction, newspaper or classified ad section. Compared to the price of a decent Sliding Compound, and "vintage" Radial Arm Saw, with a bit of TLC and new Freud blade might just the thing you are looking for!

Shop Made Sander - That Really WORKS

"If you HATE SANDING, and all the dust that goes along with it as much as I do, this article will interest you. I think I have every "sander" ever conceived of just to try to cut down on my "sanding time". A few years ago at one of the Wood Shows, I happened to stop at a booth that was demonstrating what looked like a little home-made sanding device". It looked intriguing but I wondered how well it would work. On the trip home from the show a friend mentioned he had purchased one of those little "V" Drum Sander kits.

Hmmm ... I thought maybe there was something to those little sanders. A few weeks later I went over to his workshop to see how his little home-made sander was working ...

To read the full article , click "read more" below.

As it turns out he had finished building the little unit, but had not used it much. He told me that it seemed to be working OK, but that it took him a while to realize that the adjustment of the table height was critical and when this was done the sander seemed to work just fine. Since he didn't offer to demo the sander, I was somewhat skeptical about how well it worked and didn't give it any more thougth.

Skip forward to the next Wood Show ... yes I saw the same booth with the same demo. There were a group of people around watching the demo and a few of them bought some of the little "V" Drum Sander kits to make their own ... again I passed on buying one, though I continued to be intrigued. As luck would have it, a few months later while visiting another woodworking buddy, I noticed he had, what seemed like a fairly well used home-made sander tucked under his work bench. I asked him if it was one of the kits we had seen at the Wood Shows, which he confirmed it was ... and added that it was a great little tool that he used quite a bit.

Fast forward to the NEXT Wood Show ... I finally broke down and bought one of these sanding machine kits. I purchased the 18" kit, which consists of a couple of steel pulleys, a link belt, 2 low-profile bearing blocks and of course the 18" drum. You have to supply a small quarter or half horse motor, and of course the wood to build the sander. My kit also contained two sets of instructions for constructing the sander, one a deluxe floor-standing version, the other a more modest portable model (shown in pictures), which is what I elected for my small shop. The plans are simple, one sheet of paper with a parts list and size on one side and a blow-apart diagram on the other.

I cut out all the pieces as described in on the sheet of paper ... then had some fun trying to figure out which pieces connected to what. It's a bit like putting a jigsaw together but if you are in anyway mechanically minded, it's just takes a bit of time. In small type on the plans there is small phrase that states "adjust plan to size of drum". You may also need to adjust your wood thicknesses to fit the plan if you use other than what they recommend (which I did in a couple of instances).

Well, after a few days of off and on tweaking and adjusting, my sander was ready to go. I decided to heed all the information given to me by the manufacture and my friends who said ... the height adjustment of the top is critical to good results. What they meant by this is that the actual drum needs to be below the table when it is turned off because the centrifugal force of the sand paper on the drum will lift it just enough to sand your wood once the drum is spinning.

The sandpaper that attaches to the roller is a hook and loop type and comes in a variety of grits. I was surprised how easy it was to change grits. The first few times I tested the sander I found that I had over compensated and raised the table too much, and had to lower it a bit at a time. I even marked the head so I could see how much movement was required in raising and lowering the top. I was also astounded how quickly this little sander was working just as I had seen at the Wood Shows. One small hitch I ran into was that ... I found that somehow a one of my wooden support blocks seemed to be slightly lower than the other which meant that drum was sanding more on one side of the table than the other. (Actually I think the problem was that hinge was slighly higher on one end than the other) The fix for this was to simply raise one of the two bearing blocks by shimming it with bit of thin metal I had on hand. If you look closely to the image with lid up you can see the copper shims used to raise the roller bearings.

Once I had the blocks even with the top on each side, and adjusted the height of the table accordingly this little sanders works remarkably well. You can adjust how much wood to take off by the grit you use and how many passes over the drum you make. I still find I need a tiny bit of finishing sanding on some projects before finishing, but the bulk of my sanding is now done on my little portable home-made sander. And there is a bonus ... because of the design and materials used in drum, this sander is virtually dust free ... that's right, almost dust free. Most of the dust collects in the small drawer in the front for emptying later. If you really want you can connect you dust collector, but I hate the noise so opt to let the drawer collect most of the dust.

I purchased some rough-cut Broad Leaf Maple some time ago and found that much of it tends to tear in the planer, and that the only way to get dimensioned wood is to have it sanded to dimension. This little sander does a great job of doing that.

If you can't wait for the next woodshow to get sander that doesn't blow your years budget and works exceedingly well ... check out the manufactures website ... and tell Paul you read about it on Woodworkweb

The Agony of Setting Jointer Knives

 "I often wish I was one of those dedicated woodworkers who loved to spend hours of their time "fine tuning" their equipment and sharpening tools to a razor edge. Sadly, I love to spend more time cutting wood than fine tuning the machinery. This shortcoming has disadvantages. Some time ago (I embarrassed to tell you how long ago) I purchased a very nice, brand new 6" Delta jointer. A fine machine, factory set up and "ready to go", or so the salesman told me.

When I got this machine home, I used it for many months (many, many months) and became more and more dissatisfied with it's performance. Oh it ran fine, but for some reason it would not joint a straight edge. I purchased a very expensive straight edge to check the infeed and outfeed tables and they were well within tolerance.

I became more and more frustrated and even considered selling the jointer -  click below to read what happened next

I often wish I was one of those dedicated woodworkers who loved to spend hours of their time "fine tuning" their equipment and sharpening tools to a razor edge. Sadly, I love to spend more time cutting wood than fine tuning the machinery. This shortcoming has disadvantages. Some time ago (I embarrassed to tell you how long ago) I purchased a very nice, brand new 6" Delta jointer . A fine machine by all counts, factory set up and "ready to go" or so the salesman told me.

When I got this machine home, I used it for many months (many, many months) and became more and more dissatisfied with it's performance. Oh it ran fine, but for some reason it would not joint a strait edge. I purchased a very expensive straight edge to check the infeed and outfeed tables and they were well within tolerance. I became more and more frustrated and even considered selling the jointer .

I read two or three articles on "how to use your jointer" properly and still it was delivering cuts that my tablesaw could easily beat (especially with Freud's Glue Line Rip blade that I love so much). I even made a fancy holding device like one article suggested still I got rounded results.

Finally I found an article somewhere, and I don't even remember where, that explained that if the jointer knives are not set properly, unsatisfactory results will be obtained. The article went on to say that if the knives are too high above the outfeed table the wood will have a "snipe" at the end (a place near the back of the board that has extra wood removed by the cutter). The article also said that if the cutters are too low the resultant cuts will be bowed  which is exactly the problem I was having.

Now I was in a conundrum - do I sell the jointer as is and get a bigger 8" that I want anyway, or do I try and fix the problem? I looked for article on how to set jointer knives and found them somewhat conflicting, so decided to talk to some woodwork buddies. The first one I talked to told me he set them up, as level with the out feed table as he could using a strait edge, then rewired his jointer motor to run in reverse and ran a fine, flat sharpening stone over the knives to get them perfect. Since I am not an electrician, and I felt this was making something much harder than it should be - I called another buddy. My second contact told me he now had also been struggling with setting knives and now had the perfect solution and he showed me a pair of very sophisticated setting jigs. He went on to say that these now made his settings perfect. Since I was in the neighborhood, I decided to talk with yet a third buddy. He just chuckled, shrugged and shook his head,  "I don't worry too much about it" he told me, and with that I thought the best advice was the two little jigs, and off I went to the tool store.

At the tool store I asked one of the salesmen where their fine adjustment measuring tools were? He asked me what I was looking for and told him, Jointer knive setup device. He immediately walked to the end of one isle and handed me a small flat wooden box, "there ya go" he said, just what you need. I opened the box to see two long black square bars. "These weren't what I was looking for" I told him  then I pointed behind him to the pair of jig holders one of my friends was using. "Those are for planers" he told me, what you are holding are for jointers". He went on to explain that when you are setting up a planer, the knives all need to be the same height to one another, with a jointer all the knives need to be the same height as the outfeed table and that the tool I was holding, with two back, square rods, which had magnets in the bottom would do what I want.

I was beginning to think that selling the jointer would have been easier, but I struggled on and purchased the recommended tool ... with the two long black square arms. Since there were no instructions in the box, I surmised either this was really meant of woodworkers (who hate reading instructions) .. or, setting up the blades was not going to be that difficult.

The instruction book for the Delta Jointer was helpful. I suggested that each blade needed to be in top-dead-centre when setting the knives. Now my eyesight isn't the best it once was, so I decided that as long as each blade was set in exactly the same place, they would all be the same height, so I etched a line in the front of the table where each blade would be aligned to, and set about setting up each knife. See the white arrow that shows how the square aligns each knife for setup.

After setting all three knives, I decided it was time to test the jointer. As I ran the first piece of wood through, I could feel it was finally working. When I looked at the edge I had just created I noticed a slight "sniping" at the very end. On closer examination, I could see the blades were all a few thousands of an inch high.

To solve this I purchased two inexpensive flat feeler gauges and used them between the knife setting tool and the blades. I found that 6 thousandth was perfect, so re-set the knives. This time the wood ran through perfectly. I ran several other pieces and type of wood all perfect.

There is a strange feeling that comes over oneself when you finally accomplish something that has been bothering you for many, months. I had a new excitement about this tool. Lucky for me, it had not been used much so my blades were in great shape. I will now purchase a spare set of blades so that when these are dull I can put sharp one in as I am taking the dull ones out and save a bit of time and be able to use the machine while the other blades are being sharpened.

I wonder ... maybe I should change my ways and become one of those dedicated woodworkers who spends the time fine tuning and sharpening  what a pleasure working with tools that are sharp and set up properly.

Rockwell Hardness Scale for Sharp Woodworking Tools

 "Make Your Own Tools" the article said. I love the idea woodworkers making their own tools, so I decided to make use of some plans in an old woodworking magazine, and make myself three nice marking tools that will leave a crisp fine line on wood I am marking for cutting. The article said it was easy, and I liked the idea of using hardened steel and my own woodworking skills to make some of my own tools. Of course the first thing to do is obtain the materials, so off I went to the "metal supply store" to purchase the steel material for the blades. I asked for a piece of steel, according to the instructions. The grumpy salesman then asked "what hardness do you need?". I was totally lost ... what hardness of steel did I need? the article didn't say anything about that.

I tried to explain what I needed the steel for, but both of us had lost patience with my lack of knowledge, it was time for me learn a bit about steel, and here's what I found ...

Back in the early 1920's (the exact date is a bit fuzzy) a metallurgist by the name of Stanley Rockwell (wow, what a great name), needed to devise some way of determining the hardness of ball bearings. As the story goes, his simple idea was to place a penetrating tip on the steel to be tested, and with careful measurement of pressure, see how far the tip penetrated into the steel. The depth of the dent left would determine the hardness of the steel.

Today we use the same idea, but in a more sophisticated tool with precise measuring accuracy. As a rule, most of the steel you find in woodworking tools, like chisel and plane blades are measured in the Rockwell "C" scale, hence th expression "Rc". The number that follows the Rc code is used to denote how deep the tip penetrated into the steel, the deeper the penetration, the lower the number and the softer the material, so an Rc90 would be harder than an Rc60 for example.
In real tests, today they use diamond indentors and apply a fixed amount of pressure to the diamond tip, then measure how far that diamond tip penetrates the steel. So with 150kg amount of weight, the diamond indentor might penetrate a piece of steel to a depth of .038" - this means that this particular piece of steel would have an Rc harndness amount of 28. By contrast, still using 150kg amount of weight on a harder piece of steel, the diamond indentor this time only penetrates the steel to a depth of .022" - in this case, this piece of steel would be recorded as having and Rc of 69.

The reason there are so many different degrees of hardness is because different tools are required for different jobs. If steel is very hard it is more difficult to sharpen (often requiring special sharpening tools) and it is more brittle. For example a quality turning chisel like a Robert Sorby that are hit with a hammer will have a slightly different hardness than caving knives that are drawn by hand and sharpened frequently. If it is too soft, it won't hold an edge long, which means it needs re-sharpening often or it bends. Such is the case with a hammer. Carpenters expect to hammer nails all day without the hammer's head chipping away or bending. This is "balance" of creating the right hardness. There is also a trade-off in the flexibility of the steel. Softer steel will flex, hard steel will not, in fact if steel is too hard it chips, because it is brittle, which makes it even harder to sharpen.

Sawblades are a great example of combining various degrees of hardness. A saw blade might have a hardness of say Rc50 but the tungsten carbide tips might have a hardness of Rc90. This is so the blade can still flex somewhat (without breaking because it is too brittle) as it moves through the wood, but the tungsten carbide tips which do the actual cutting will last longer as they are harder than the steel. Freud Tools have made a real art out of combining different degrees of carbide to their different saw blades to achieve a wide range of saw blade uses. For example the carbide used in their Laminate/Melamine blades will be slightly  harder than the carbide used in their famous Glue Line Rip  woodworking blades because the  hardness and content of the laminate compared to wood is much different.  But there is also a limit to hardness as it compares with brittlenss.  Freud  actually use a slightly softer carbide in their metal cutting blades because a softer carbide is less brittle, which is what you need for cutting hard metals so all the teeth in the blade don't shatter. (Editors note: carbide is NOT metal, it is only used as a comarison element in this article because most woodworkers are familiar with both hardened steel and carbide)


Most highspeed steel such as what you would find in bench chisels and woodturning chisels are around Rc60. This is because they hold a good edge, but are still reasonably easy to sharpen. Robert Sorby , arguably the finest manufacture of wood turning and carving chisels, is well aware of how important hardness is tool making.

If you had a bench chisel with an Rc90, any time it fell off the bench onto the floor it would chip or fracture, then and you would have to send it somewhere to get sharpened because it is too hard for most conventional sharpening methods. The same thing that happens when you drop a carbide tipped router bit on the floor or bang a carbide tipped saw blade ... the carbide often chips. You now have a very expensive fishing weight, because ANY chipped carbide blade should NEVER be used in a power tool again ... at least if you value your eyesight, as flying pieces of carbide from a highspeed tool can cause serious (and often permanent) physical damage.

And so, back to my tool. I finally decided that the best hardness was that similar to a bench chisel where there would be some flex but that the maker blades would hold their edge longer, and that is exactly what I purchased. Now all I need to do is find the time to make them.
