Received a new flange yesterday, and I realize it will have to be fit to the rim. So close, but just won't go on. Before I have any filing or machining done, what are thoughts on putting the flange in the freezer, allowing the metals to expand, and then trying the fit again.?
Just a thought..!

For metals freezing contracts, heat expands.  The only thing I think that expands is water when frozen.  I'd get the rim properly fitted. You don't want it so tight it "chokes" the sound.

I guess my thought was if the metal flange contracts with cold, the ID of the flange would be greater allowing surface clearance around the rim. As I said,
it was a "thought", and the forum is a great place to get the ideas and experience of others. Thanks, kb

I'd get the flange fit to the rim and not the other way around. If it's an
original TB-1 rim, I'd leave the rim alone.

I have an extra original TB1 flange but it's a shoe and plate flange, what's yours?

If the metal contracts, the ID would get smaller.

The flange is new. The rim is pre-war. I agree with others: Machine the flange to fit the rim.

24 hole flange, round hook/nut hardware, with a flat upper tension hoop. I'm going to
"file-measure-file-measure" the new flange to get the fit I need. Only way to learn skills
is to practice.. looking forward to spending some quality time with my new flange.! kb

Oh. It's an old flange. I'm going to guess that even if it's a pre-war flange, the existing damage has reduced the value enough that filing the inside can't diminish that much more.

Maybe a job for a Dremel?

Good luck.

It can be done with a file, but take your time and go slowly, taking just a little as you go around. It's easier to take off wood than to add back to it. I've done it with a dremel and also with a file. I now have a lathe  to do that with now.

Yesterday with a couple new files on-hand, and a couple hours to spend in the shop, I filed and measured and checked the fit of the flange. Finished it up this morning, and am pleased with the result, not only the fit.. but that I researched this project and decided that I could accomplish the fit, and save some $$ for another project.
