I needed the ID at the top of the bend.

I guess I still don't know what you are trying to do lol. I thought you were trying to cut it in half still. Good luck though!

Honestly, I am not so sure I do either

@NoHaveMSG easiest way I know to mark the center line of a circle....

Take a board (or cardboard, or whatever) and make a straight line down the middle. Then from the bottom of the line, form a V with two boards at a 45 degree angle from the base of the line. Now slide whatever you want to mark into the V and follow the line.

You can also cut the line through the board, turn it over and make the mark that way, or use the jig and the line to cut the object.

It also has the advantage of working for any size object that fits in the V.

Amazon sells something similar that uses a ruler but I like mine better because I can make it any size I want.

I have a similar jig I made for a table saw that lets me cut half circles if needed, and works for cutting wood for picture frames (45 degree angles). Saw this a 100 years ago in one of the woodworking mags.

lol, i would've just chop-sawed it in half.

the lug nut holes are centered, so i'd just mark across the lug holes, and chop saw those. instant direct center.

Remember when a hundred years ago meant 19th century?

That's a neat trick. Thx!

Wouldn't fit in my chop saw, or the dry cut, or the band saw, or the mill base.
