In my quest to find a better ultra-lightweight ballhead than my current
Slik standard, I bought a magnesium Velbon PH-263 based on Kerry's recommendation. It is lighter than a Slik, and appears to be as strong.



What I am trying to do is to replace the stock mounting
assembly with an Arca-style quick release platform. I have a QR2 from Kirk that has
a standard 1/4 threaded hole. Problem is that after I remove the stock platform,
I am left with a screw stud that is not 1/4, but is slightly smaller. There appears
no easy way to change that screw. So how do I matte that screw and the QR2
platform, possibly in a non-permanent way ?
I have asked Kirk to make a custom QR2 with the appropriate thread size, but he has declined.
