Miters, miters, miters…

Very nice sled. One way to adjust the miters is this.

Yep, and a way to bu**er them up is this. LOL

Ah, the duality of planes in a nutshell. In one man’s hands, a way to create a glass-like sheen on end grain.
In my hands, a torn-grained, edge-chipped-off fiasco. Thanks for reminding me about that jig Don. I just generally despise miters, but they are so versatile, and look so good on your boxes, I’m going to have to make that jig.

Don:

If the “A” board is always on the left side and the “B” board is always on the right side then the blade being not exactly 90 Deg with the surface will always have its out of alignment being compensated by the wood being cut on opposite sides of the blade.

I had a person who makes segmented bowls show that trick when sanding segments to be glued together.

If you make another of your 90 deg sliding sleds, but set the blade at 15 degrees then the two pieces will be 90 degrees but the corner edge will not be straight up and down, but will match perfectly. An interesting design modification.

Thanks, Karson.

I think we are saying the same thing. The principal of ‘self-compensating errors’ works with a number of cuts.

I like your idea of tilting the blade at an angle – this would be a scarf-miter.

I realize we were saying the same thing. I just wanted to point out by using a larger “out of alignment” cut would still give a flat 90 deg angle piece of wood.

I had not known the term scarf-miter, something new I learned at 11:50 PM the day was almost over without be able to say that.

Not really true I was working on a vacuum storage system for the last 2 weeks (vacation in the middle) and i still had a vacuum leak. Almost all gone but silicone glue helps to plug vacuum holes by letting the vacuum suck the glue into the small holes.

The leak is still about 7in of Hg loss of pressure over 6 hours.

Don,
I’ve got a sled just about like yours. I made removeble faces from 1/2 inch MDF. I can adjust the angle with playing cards under the faces. That’s if and when they are out of square. I also use PC stick on sand paper, 110 grit next to the fence. It really holds. this is a good thread for the new guys because nothing is more frustrating than miters. Dang, I still need to make that shoot board!!

The 1st thing I’m going to do for my boxes is to build that jig. Thanks Don!

Very simple, but an excelent idea. I have been struggling all my life using a single miter to cut.

By the way your maths are a little out the error is 0.15° (3×0.05° error per joint)

Thanks, Tony. I’ve corrected my error above.
