Too Big?

[DeeDub76]

Has anybody come across a Park Tool reamer that reams slightly too big? I recently purchased a new Park reamer #788, which is supposed to be 43.95mm. But, after reaming a head tube I can literally press in my King headset by hand. In disbelief and frustration I reamed a spare HT and sure enough....too big again.

I have a friend who had same problem with the same tool. He used it on his new custom frame and cups pressed in by hand. For the record he is a professional wrench (15+ years) at a great shop with plenty of experience using frame prep tools.

Saves money on buying a headset press.

Have you measured what it's cutting to? CK headsets are often said to be slightly undersized, and I've sometimes found them to be quite easy to press in compared to other headsets.

which Headtube stock? I've never had a problem with a beefy paragon tube and park reamer but have had a loose-ish fit on the trutemper tube that's much lighter. It didn't even come all that round. The thinner tubes will have more potential distortion.

i have the same reamer and it still required pressing of a cane creek 40 headset.

I THINK you can call up and King and they'll do a slightly oversized version.
