I have a Huber Vintage Rim out of a 2010 Lancaster. I tried a Prucha Flange but it is too small. The inner diameter fits over the rim, but the larger diameter of the notched part doesn't fit over the larger part of the rim. Sorry if my terms are incorrect, I've never done this before. I thought I measured well, but I can only measure to the 16th of an inch and I guess that's not close enough.

Are there multiple sizes for Prucha flanges? Everywhere I look lists them as the same. If not Prucha, who else? RK? I don't see a way to just buy a Flange on the Huber website.

As I understand the world of masterclone parts, there are two different sized flanges - as regards the inside diameter. A little difference is important for prewar versus 1950's. Here's a link to Elderly's listing of both Recording King flanges.

I considered the RK flanges you linked. However I'm not sure if either will work. They're the same lip diameter, which is what's too small.

The Prucha and both RKs are listed with a lip diameter of 10-15/16. That's the part that's too small. The inner diameter of 10-11/16 (23/32 for Prucha) works just fine.

How tight are flanges supposed to fit? I didn't want to force it and risk bending the flange or chipping the rim. Is it a slip fit or do I really need to beat it on there?

The flare of the rim is supposed to stop the flange, resulting in a very tight fit as the head is tightened. You may need to have someone fit the flange to the rim. This drawing from Stewmac shows how things should go.

I have experienced your frustration myself. I find variation In flange sizes, even from the same mfg. I had a rim needing a flange a few years back and had 7 flanges here and none fit. You need a 12" caliper to accurately measure both the needed ID and the step down to thousandths of an inch. Then, maybe some of us could help you. If not, you will need to have a machinist turn the ID to fit. I think Huber can do it as well, but you may find someone locally. I personally do want a slip fit. I think a tight flange has a similar effect to a tight tone ring. Good luck!

I have experienced the same problem you are describing many times. I have personally used hundreds and hundreds of Prucha flanges and they are the most consistent flanges being made today. As far as I can remember there have only been two different sizes, but within each size the flange to flange consistency was very high.

Don’t sweat it too much though, you are not dealing with a pre-war Gibson rim that is un replaceable. Huber rims are good but they are still in production and can be found, just like you came up with yours. Just get the rim re machined to fit a new Prucha flange and start picking. You will drive yourself crazy trying to find the one flange to fit your rim and I really don’t feel like it will diminish the value of your newer rim.

Just my opinion

Thanks, Eric

Thanks to you all for the help. I'm not keen on modifying the rim, but I'm also not interested in trying a dozen flanges to find one that works. Unless I could find a warehouse full of them rather than paying to ship. This is going to be more complicated than I thought. Certainly not as easy as building a computer. That's a good thing, I suppose. A learning experience, for sure.
