Arca B1 clamp removal advice needed

[lawrence_beck2]

I have an early version of the Arca Swiss B1 head. I'd like to replace the stock

clamp with a Really Right Stuff Lever Clamp as I need something more "secure"

with which to secure my heavy Leica R glass. RRS indicates that the newer

version of the B1 head uses an 11mm bolt to secure the clamp to the B1 head.

This can be removed with an 11mm socket.

 

My head predates the version RRS referred to and has a round, flat retaining

screw that has no surface to grip. RRS advises sending the head to Precision

Camera in Chicago to have the clamp removed. I'm assuming they'll drill the

existing screw out, but would rather not be without the B1 head for several

weeks while the head is in Chicago. A machinist could probably do this... but

I've just moved to a small town and would rather not trust this job to someone

I'm unfamiliar with. I'm hoping that someone on this forum has tackled this at

home and can advise as to how to proceed.

 

Thanks,

I have an Arca B1 ball head I bought second hand a few years ago that became frozen. Great head. I sent it to Precision and they charged $81 including return shipping to clean, lubricate and adjust it. It came back as good as new. Might be worth a call to them. Good luck.

Whats wrong with the roginal clamp? The screw clamps are a bit slower to use but are actually more secure than the levers. Anyway, to get the clamp off couldn't you get a dremel or similar tool and cut a slot into the screw? Then you could use a screwdriver to get it off. Just an idea for you.

A screw/pressure clamp is inherently more secure than a lever/spring clamp.

I suggest you call RRS. They are very helpful.
