the frame is at the welders, now i just need to finish the fork. Aaron and others, the steerer tube was a 1" threaded, fork is 1 1/8 threadless, is there a conversion headset to make this fit?

It's called an End Mill and a TIG welder. Your ::edit:: HEAD TUBE ::edit:: precludes the use of an 1 1/8" fork. You could have the welder put a new head tube on it though.

ok but really, many hours spent with a file and i should be able to fit a threadless into a 1" right? i've got the fork in there with out a headset and there is still wiggle room.. yearly miles will be under 500 so i'm not too worried about wear. thoughts?

The concern is the headset cup shoulder is going to add thickness to the inside of the head tube. Once you add the cups, there will not be enough room for the fork.

If you "file" the head tube, it will no longer fit headset cups.

In theory, you could use an externally press fitted cup adaptor, but you would have to make it as they don't exist.

ok, how about this. i've spent many hours on this and don't want to re do any welding/ cutting/ fitting if i don't have too. the fork is a very stout d/h tripple crown, so this might work. what about milling the steerer down 1/8" that's 1/16 on the wall. i could then either run a 1" threadless or 1" threaded if i have the steerer threaded. thoughts?

Seems reasonable. Define "stout" though. And what is the fork steer made of?

stout... it's a d/h fork, with thick wall steerer, aluminum. because it is a tripple crown i'm not too worried about milling anything down. hey aaron, you got a mill at the shop don't you?

i was going to employ you to belittle it and make it feel like a little worthless steerer. easier than the file.

A chopper head tube and steerer take a lot of stress. You don't want to be removing metal there. The best solution is a new head tube. However, you might be able to add (braze) a 1 1/8" compatable head tube section on to each end of the existing frame. I am assuming the frame is steel.

I bet David Wilson could help you. Chalo might be interested. Also my landlord Kenny has a full machine shop out behind my shop and he loves to tinker. What you need is a scrap frame with a 1 1/8" headtube we can cut some 1" or so sections out of.

This might be more work than just welding in a new head tube.

Milling down the steerer might be an option if it is thick enough. But probably not a good idea.

Or you could just wrap the steer tube with duct tape, jam it in there and call it good!

Yeah, going with a 1-1/8-spec headtube is the way to go.

If you are stuck, I can make you a bastardized steerer tube to fit the fork and frame. That would be ridiculous, but it is a chopper...
