The idea came from FWW

I got a chance to play around with getting the angles setup for the adjustment wedges tonight. I made a fixture to cut the angle in some scrap. I didn’t pay real close attention to detail on the fixture. I figure it’s a one of a kind item and probably will hit the compost pile in the spring.

I don’t particularly like the bungee cord idea so I’m going to use a 1/4-20 bolt to keep the adjuster in place. Here’s the concept:

I’ll drill a hole through the center of the adjuster and counter bore a hole deep enough to allow for adjustment up and down. Since the entire fixture / jig is basically hollow, the bolt will just float to keep the adjuster in place.

I used AutoCAD to make a template @ 15 degrees. I used some 3M77 to stick it to a piece of 1/8” hardboard and used a jigsaw to cut it out.

Adjuster angle fixture.

Here’s the test piece in the fixture. You have to keep your wits about you when doing something like this because the piece isn’t backed up by anything. If your not careful, disaster could strike before you know what hit you!

Here is the 1/8” pattern in the test piece that I cut. It turned out really well considering I didn’t spent a lot of extra time and effort making the fixture look pretty.

I’m not sure when I’m going to get this fixture completed. I may put it on the back burner for a few days (read as I plan on just picking away at this project over the next few days) as I need to work on my dust collection and get some permanent piping installed.

If you have any experience with this fixture, I’d love to hear how to made yours, is it really worth the effort, ...

Thanks for reading.

I used the FWW idea in a primitive way. Just a sheet of 1/2” MDF and then ordinary big box store shims that I had routed slots in (actually all the way through the thick end). In the bottom of MDF I had drilled and countersunk holes for the #10 fasteners. Then pushed the shims in until contact with the board, tightened nuts while holding the threads with plastic tipped pliers.

Not the most adjustable since the shim travel is set for the width you are working with. Worked well on the three boards that I did.

Well I’ve got the jig just about finished up. I need to do some sanding on the adjusters. For what ever reason they are really tight. I checked them when I cut them and I thought they were fine, but noooo.

I do have one question. Is there another option for reducing the friction on the bottom of the jig besides laminate? I’ve sanded the bottom side up to 220. Can I just wax it? I was thinking about adding a few coats of varnish but I’m not certain how well that will work. If laminate is the way to go then so be it.

Anyone have any suggestions?
