Threaded Fork Problems
So I've got a bit of a problem.
I gave my 53cm Univega frame to my girlfriend so that she could put together her own bike. The fork had been damaged in an accident, so I picked up a new one off ebay. The measurements stated in the auction made it seem like it would fit but... it's about 3mm shy of being able to have the locking nut(?) thread on. Now, her dad machines drag racing engine blocks for a living, so we're thinking that maybe he can just cut down the top of the steerer tube with one of his neat cutting doo-hickies by a few millimeters and have everything line up. However, I was wondering if maybe a threaded to threadless adaptor might solve the problem provided I got a threadless headset.
Could this work? I think that he could cut it down and have enough space to still fit the headset cup, but if not... I don't know. It seems like a lot of work, but she likes the fork a lot.

Bikes: highly modified specialized crossroads and GT hybrid (really a [formerly] 12-speed bmx cruiser, made before 'hybrid' took on its current meaning), as yet unmodified redline 925, couple of other projects

if the only problem is the steerer tube being too long, you can toss in a spacer or two.

You might have some luck with headset with smaller stack height, depending on your current one.

you could face the head tube down about 3 or 4 mm so that the headset stack is lower. take it to your lbs

that was the OP's plan, his GF's dad has a machine stop.
and it is a good idea. just make sure you go down far enough to get plenty of thread engagement. and make desperately sure that the top and bottom faces remain perfectly parallel. maybe even have the LBS re-face it once you grind it down.
