Standing 45 deg. T/S miter

[munzieb]

Looking for a quick project yesterday and came across a plan for a standing 45 degree miter sled for my table saw. I have an old craftsman and cranking in a 45 degree angle on the blade can be like hauling in a anchor. I have a digital angle gauge but it still takes time to tune it in. I had some scrap plywood a T-track and miter bar. I also had a hold down laying around so I thought I give it a try. The 45 cuts on the base and sides were not too bad but I needed to use my Incra miter to cut the side supports. I didn't realize the sides I was cutting extended past the edge of the table saw and the Incra slipped and hit the floor! It took a few minutes to recalibrate everything. Using an artist plastic 45/60 degree miter comes in handy for setting things up correctly. My stack dado did quick work for the T-track.The test piece of oak came out with a perfect 45 degree angle. At some point I may want to revisit this project and modify it to make 30, 22.5 and 15 degree cuts.

BTW, the lower angle of the top plate is upside down. The angle cut needs to sit flat on the lower plate and line up with the angle of the lower plate. Tip. use 2 sided carpet tape strips to hold everything together until all the screws are in place and everything is properly aligned. This is especially important when mounting the miter base piece and track and aligning it to the saw blade.

I think we have something in common.... I love to make jigs!!  I have two shelves, in a big metal cabinet, full of jigs I have made.  Some I have forgotten what I used them for!!

That looks like a very useful one.  I'm curious how you would modify that one to do other angles.

Still thinking about it. Not expose the lower plate to the saw blade and retain the sharp angle on the top plate. Use some sort of piano hinge on the base. Rather than using the solid side pieces, create some sort of slotted radius arc on both sides with stops for 30 and 22.5 degrees. I need some more staring at a blank ceiling in the middle of the night before I get it right. LOL!

I'm thinking it would be easier to make separate jigs and they would retain their accuracy. (?) Please let me know what you come up with.

You are right but they do start taking up some real-estate. I would probably do the 22.5 degree first because I use it for making multi sided boxes.

Wood magazine, issue 121, Feb 2000. They used it for a drill press jig, but - - -

Interesting idea!

Great jig, I love to make them  as well.
