Hello all and Merry Christmas! I have an old 1950 panther staightbar frame I recently bought. I’m trying to put fork bearing cups in it so I can start putting it together. But all of them fit a little loosely. Not majorly sloppy, just loose enough to spin freely in the frame. This is the same, top and bottom no matter how many different races I try. Does anyone have any home remedies for this that don’t involve welding or brazing the opening up to make it smaller? I’ve heard rumors of people having success using JBweld to build it up slightly, sanding it to fit and then tapping them in. Just wondered what you guys suggest. Any help will be greatly appreciated. Thank you,
Danny

They always fit tight after they have been repainted. Maybe you can paint the inside of the headtube with several coats and give it a try? Barry

Throw them in, and clamp them down. Then tig weld all the way around them. That should keep them in place

Why not use some super thin tape around the bearing cup to act like a shim.

I thought about that. I thought about using some beer can material as a shim. Just didn’t know if that would work or not. As cheesy as it sounds, the idea of building it up a little with in weld and sanding it to fit sounds like it would work.

lol I was saying put them in place and weld them to the frame lmao. Totally joking. Your idea of building them up would take to long. And no one likes to grind hahaha

On a more serious note, has anyone considered using frame blocks like these to slightly compress the tubing to a uniform, snug fit? I know these are intended for dents, but it occurs to me that they might do the job.

Crazy! I’ve never even seen those before. Those would surely do the job. It’s just the slightest bit flared. Those are really cool. I’ll google them and see if that’s a possibility, thank you!

Hi. Everybody. Merry Christmas. What. I did on my 48 was put a cup meant for locking fork. The increase in length often makes the difference. Now the cup locates into the part of the headtube unaffected by wear worked for me

That’s a great idea. But finding two of those may prove to be a challenge and an expensive one at that. But I like the idea and will see if I can put my hands on a pair of those.

I wouldn’t even be opposed to buying some fancy aftermarket aluminum one from White industries or somebody like that if I could get an accurate measurement on the frame
