I used a very simple design with this jig. There was very little time involved and it cuts 45s perfectly. It took a little thought trying to figure out how to get the fence dead on. I came up with a simple solution. I got the fence as close as possible with a combination square, then i placed a carpenters square against the fence and clamped it to the sled. Then i simply glued the fence in place using the carpenters square as a guide. The fence is probably not at a perfect 45 to the blade, however the fence makes a perfect 90. Therefore as long as each side of joint is cut on opposite fence, joint is always a perfect 90. Thanks to all who have posted on cutting miters. Your info helped me figure this one out. I killed a few too many brain cells on something that turned out to be very simple.

I have already killed all my remaining brain cells so I won’t build this but I can see that this is the answer to a lot of prayers to the God of Mitres.

OK, I am going to build a new one. I like your design better than mine.

Your sled is very nice and well made. You even took the time to add edge bandings. I particularly like your slotted guide bar to accept the stop block. By the way, I wonder why you didn’t make two stop blocks, one for either sides ? (just wondering)

It’s incredible what someone can come up with when time required is insvested. Great job !

Thank you for all the comments. Bricofleur, the edge bandings were added because i was wanting to try out the jig and what kind of miter jig has no miters. As far as the stop block is concerned i ill probably make another one, however i dont think in need one. Ive been using the right side of jig to cut one side of joint and then the other side of jig to cut and size piece. Just like everything else i do im sure eventually i will need to add to it. Come to think of it, an additional stop would help keep work piece from moving. Now im just rambling.

Nice Sled –
You came up with the same idea of making the two angles = 90 degrees. I think this is a good solution. Thanks for sharing.
