Custom "square" - Peter Tremblay - 02-24-2018
Hello all,
I'm not sure where to post this question but would anyone know of a place to order a machinist square in a custom angle?
I really like these types of squares.
[attachment=8523]
However I'd like one made at 50*
Would anyone know of a place to order something like that?

Two options to avoid paying a boatload to a machine shop:
Starret protractor.
Possibly a plastic square, not sure what they are called. But extremely accurate if you could find one in 50 degrees.

I have made two custom squares , 24° and 18°. These were for a cabinet maker that specialized in coopered tops for chests etc. He uses these to check the angle of saw cuts on the staves .
I have metal working machines so this was not a difficult job. I machined dead flat a bar of steel 3/4" x 1-1/8" x 3" long. Then sawed a 1/16" slot for the blade 1" deep. I used a sine bar to get exact angle. Pre drilled four 3/16" holes in the steel bar. After aligning the blade for angle I epoxied the blade to the bar. Next day I bored thru the existing predrilled holes with an undersized drill, about .180. Then reamed to .186 which is .001 under the brass rod I use to form a rivet. I turn a small chamfer on each rivet 1" long and drive it home. The rivet is milled flush on each side.
I think you could do something similar. Instead of steel bar ,use hardwood . Band saw a kerf , predrill for rivets and epoxy the blade to 50° angle . I used 1/16 x 1" tool steel for the blade as it is straight and flat.
Mc Master Carr is one supplier ,there are many.

Thanks, Mike!
That's a great suggestion

This may be accurate enough for you if you don't want to make one yourself...

Actually, if you have an orphan protractor head for a combination square, that would be a more flexible option, just set it and forget it. You can get a "blem" PEC head for $25 from Epstein, and they are pretty good, more than good enough for woodworking, and your 12" rule from your combination square will fit, or you can buy another one for $10. PEC makes good stuff and these blems are a bargain. Link:

How much do you think a custom machined square will cost you? I figured North of $100.
RE: Custom "square" - Foggy - 02-26-2018
Harbor Fright: Multi-square $6. Combination square set $8. Set it to the angle you want forever, then drill and pin so it stays that angle.

It's not bad as far as precision protractors go, and cheaper than a "custom" made square of comparable accuracy from a machine shop...It just depends on how accurate the angle has to be. Rich is correct about the combo protractor.
