I was tired of picture frames and boxes having small gaps at the 45’s. Makes me crazy. So I decided it was time for a jig that has adjustable wings on both sides. I can now dial in 45’s with very tight joints. The new jig is safer than my old one as the blade gets buried in the center rail. The hold downs are adjustable in and out to accomodate varied stock width and height.
I may change out the SS 1/4×20 adjustment bolts for machine screws at some point and make a stop block and extensions for the wings to handle longer stock cuts. The entire carriage assembly dismounts for maintenance/upgrade.
Thought this might help somebody out there (as you all have helped me). Many thanks.

thats cool. it looks like the one i saw someone online make on some website (not really sure which one). yours is much better though as you can dial in a perfect 45, have the hold downs, and its good that you took safety into consideration and buried the blade. great job!

Hi rachet,
I have been thinking about making one of these. I have favorited it so I can use it as a guide when I get around to construction. Very nice idea.

Good idea, Ratchet. The gaps happen to me all the time. What causes that, anyway? Maybe it’s time for a new eyeglass prescription. Sometimes I think I do better with my glasses off. I’ll put this one in my favorites.

Nice job. I built one awhile back that’s similar but didn’t have the “tweakability” of yours. However, I did create interchangeable backer boards for the different spring angles on certain moldings I was using at the time. That worked well and will be a feature on the next one I build. I say that because I loaned mine to a bud and he hasn’t returned it. He knows I’ll make a new and better one when I get around to it. He gets most of my prototypes anyway.
I’m going to have to consider your setup, looks like it works like a charm.
Always,

I like your idea of adjustable stops! Makes it dead-on accurate!

Ratchet,
Very cool… That 45 degree angle is elusive. Looks like you have the tool to chase it down and nail it.

Great jig Ratchet…..... and this would be a good jig to start that “tips and jigs” tab on the LJ home page we talked about a while back. I’ve got a woodworking buddy that’s on me all the time about building too many jigs….. but I have to listen to him, he gives me lots of good lumber. The last time I went to his house he gave me some cherry and said “son, try to build something besides a jig”........ he’s pretty straight forward like that.

I like this adjustable rig better than the slider I have. I have to adjust mine with playing cards. I works but I think this one is better.

looks like a great jig to get those elusive 45 degree joints just right! Gonna have ito make one for myself for those picture frames. (One nice thing about working with almost hundred year old barnwood is that perfect miters sre not relly neccessary like on frame and panel construction.
I am designing one in my head and hopefully will get to it this summer.
God Bless,

Rachet – Thanks for posting. I have one very similar to this one. except I loosen screws through the top to adjust. I will have to modify it to use the adjusting screws, this would reduce the time it takes to sneek up on that perfect 45.

Many thanks for sharing.
I think your ajustments will also solve my crosscut sledge problem. I can make one of 89.x degrees or 90.x but never 90.
This way I can tweak it, and once right, super glue the nut, with locktight (can be removed if needed to reweek later).
Love the safety centre rail.

Thanks all. Now its time to actually post some projects…well soon anyway.
Yettiman; Loctiting the nut once its dialed in to 45.001 is a great idea. I think I’ll do that. Appreciate the tip.
