Just a Tapering Jig

I was organizing my new workshop when I came across this jig that I had built a couple of years ago. It was too long, the tapering side bowed in when I used it and it would tip toward the blade during cuts, especially if the jig was riding over the miter slot.

I put the cleaning and organizing on hold for a little while and made some modifications. First, I cut almost 12” from the length. That made it much more manageable.

To solve the bowing tendency, I added a piece of aluminum channel I had kicking around. The channel is made for thinner stock so I cut a rabbet on both sides to accommodate. That worked great! No more bowing.

To cure the tipping tendency, I made a fence rider. The jig is very stable now and tapering is a snap.

A piece of angle would work just as well, but I used what I had and am very pleased with the results. I gave it a coat of my usual treatment for shop projects….Thompson’s Water Seal – Honey Gold.

LOL…thanks Joe! I really like the aluminum stock you can get a Lowe’s and HD. It is readily available, light weight, inexpensive, easy to machine and has countless shop applications.

I thought of scrapping this altogether and building a tapering sled. I like the way those hold the work piece for you but this was quick and easy for the limited amount of tappering that I do. Also, I like the way the work piece sits flat on the table, making full use of my zero clearance insert.

The “fence rider” solves the problem these jigs have of wandering or slipping toward the blade. A little trick I forgot to mention is that if you raise the blade a little higher than you normally would, using extra care not to remove any body parts…the downward force of the blade reduces the lifting tendency. It also gives a slightly smoother cut on the top of the piece. I plan to add some type of hold-down. Knocking some ideas around in my head.

Nice jig.

That always happens to me too btw., I start cleaning my shop and then I find something. an unfinished project, cool looking off-cut or a tool that needs servicing. And then I get side tracked…

I really need to clean my shop.
