Making a Box Joint Jig for the Router Table

I have received countless emails and messages about adapting the Lynn Sabin Box Joint Jig to the router table, and that is what this article and video are about.
Some time ago, I made a video using the Lynn Sabin plans that are available on sharkguard.com, very kindly provided by Lee Styron ... thanks Lee, for doing this. The Leeway Workshop LLC provides quality safety devices for table saws, like Shark Guard, splitters and riving knives. The link to specific plans is further down this article.

The plans, as I understand it, were originated by Lee Sabin for use on a table saw, using single blades, dedicated box-joint jig blades, such as Freud Tools, or using a stacked dado blade set-up. If you have never made this jig before, it is best to read these and the instructions provided with the plans, before you begin.

This jig works great on the table saw using dado blades, unfortunately, dado blades are not available in most European countries.  I understand it is not illegal to own them but it is illegal to sell them. The plans I used are basically identical to those provided on the sharkguard.com website, with a couple of small alterations.

 

For everyone who is on the metric system, you will have to do all the conversions yourself. I do not know what router bits sizes, or threaded "ready-rod" types you have to work with. All the components I used were Imperial.

The way this jig works is based on the the "ready rod". I used a 16 threads per inch version. This means that if you have a nut on a rod like this, and turn the rod 16 times, it will advance that nut one full inch. Converting that to a 1/4" box joint, from the start position, you make one cut, turn the rod 8 times and that will advance the carriage 1/2" inch which means the second cut will leave a 1/4" pin, then make the cut at the 1/2" mark, and so on ... thus making the beginnings of the box joint cuts.

Making A Table Saw Jig for Tapered Legs and More

taper leg jigAnyone who has done any woodworking during their lifetime will know that a lot of woodworking is all about the jigs that can be made. I have seen jigs made for one purpose and one use only and other jigs for multi uses that have been used over and over again for years and years.
The jig we are making today fits in the latter category. A jig with more than one use that will provide years and years of excellent, time saving and accurate usage.

The purpose of the jig is to (1) make tapered legs, as is often seen in a variety of tables and (2) to trim boards that have curved or rough edges so they can be easily jointed or sawn on the table saw ... and who knows what other uses may crop up over time.

Then jig is a simple one and you can make it any sizes you want. I made mine 4' long and 16" wide. The reason for the 16" is that I seldom get boards wider than about 10" and these would easily be accommodated on the jig and it would still allow for a nice balance on my table saw. The material I selected for base was ...

Making a Chainsaw Sharpening JIg

I know that to get good at something you need to practice, but I just never seem to use my Husqvarna Chainsaw enough to really get efficient at sharpening the blade. I do a good job of sharpening, but I know it takes me much longer than someone who uses the saw a lot.
My biggest challenge is when I have the saw in the field, and inadvertently hit the dirt or some small rocks, I can feel the blade getting dull instantly and have to stop to sharpen it. This is where my sharpening skills need the most help. I find it difficult at best to try and hold the saw with one hand and sharpen with the other. I know there are some jigs you can buy that you can drive into the stump of a tree, then clamp the chainsaw bar to ... but I never seem to be around a big enough stump to use one of these clamps. I am however, very often fairly close to my truck, so why not build a clamping system for the chainsaw bar, that I can fasten to my truck's tailgate, that I can then spend a few minutes and make a good job of sharpening the blade.

 

I started off by measuring the size of my saw and cutting an old piece of 1/2" plywood to fit. In my case 31" x 15". Next I needed to make a simple rack that would hole the motor and handles from moving around too much ...

Making a Round Table Top With Circle Jig

Well, we finally get a chance to use the router circle jig to cut out our round table top. For this we are using a 1/4" pure carbide bit. If you are really not familiar with carbide, it is not like some form of steel. The structure of carbide is that it is more like a crystal. This means it will break before it bends, unlike steel that will take a massive force, bend and bend and then finally break. Carbide bits are much more sensitive to side pressure and if you push them too hard, they snap and are now useless. The good thing about carbide and the reason we use it is that it has a very high boiling point. This means, that unlike steel, you can subject carbide to very high temperatures and it won't melt like steel does. When steel bits melt, even partially they become dull and that's why we like carbide, it stays sharp much longer than similar steel bits.

 

Remember, the point to cutting this table top is to ultimately use this top as part of our 3-legged pedestal side table which you can see in other related videos.
