I missed part of the original post, but you can't always use the fork from a larger frame on a smaller frame by cutting down the steerer.

The rake of the fork must match the headangle of the frame. For very small frames, front center is an issue, and the headangle is relaxed to avoid foot overlap. In such instances, the forkrake must be greater so that trail does not increase too much. That is why frames with shallow headangles and short fork rakes often have wheel flop which can make them almost dangerous to ride!

Some builders may have forks of 2 or 3 different rakes in their product line.

Also, builders often change geometry from year to year, so correct forks in one year may not be correct in another year.

So it all depends. Meassure the headangle of the frame (and the bike was built with a level top tube for your measurement to make sense) and the rake of the fork. Then check back with listmembers to see if they match up in the reasonable range.
