I had the same problem - with the same search results. You buy the cam
clamp, then get a piece of steel rod (~3/8"??) to replace the original
cross nut, drill and tap any size hole you need, then cut to length.
You can buy the 1/4-20 and 5/16-18 sizes in Rockler blue...

Hi folks,

Many thanks for the replies.

My original message was badly worded in that what I am looking for are
smaller clamp handles, to fit (presumably) smaller bolts. The 1/4" handles
are about 3" long; I was looking for some that are maybe half that size.
The clamps go in a pretty tight space.

Cheers,
Nate
