Tube bending protractor

[I Lean]

I made a bend protractor.

Trying to emulate the Mittler Bros. one, which looks like this:

Mine doesn't have the nice engraved degrees or ruler measurements, but since I usually bend tubes to match the angle of the sample I have, it might not matter. (I've been using my Angle-O-Meter previously...just a couple pieces of 3/4" flat bar with a bolt through one end so they make an adjustable "V") This style is specific to each size of tube and bend radius--this one is for 1.75" tube, 5.5" centerline radius.

If anyone has any nifty ideas of how I can get angle and inch measurements on here, I'd be interested in learning. Ideally I'd have an engraver, but I don't.

Thanks for the file... Maybe you could get a good quality decal made to fit the tool and then later on make some improvements.

Very handy, thanks for the post.

add a cheapo engraver to your plasma table to get all the angles and dimensions marked
we do exhaust bending, made this one specifically for 2.5'' tubing

No help with your protractor but Ive been using this

With great results zero it on the end of the tube and bend. The protractor and the digital guage would be great. Wonder if you could mount it to the protractor dome how??

[I Lean]

I use a similar angle finder on mine, I usually just stick it onto the die and zero it before bending. Not sure how you'd use it on the protractor all the time. It would work when mocking up a bend in the vertical plane, but not so much any other plane...

Made this one for the last cage I did and then gave it to a buddy

Thanks for the file. I added a few simple notches at 22.5, 30 and 45 degrees as I do not have an engraver either. This will be mainly for polygon type fire rings so I also shortened it a bit so I can fit between the steel and the press.
