Support for big glass

[Don Herring]

Just got my hands on a Takumar 500/4.5.

My Bogen 3021 tripod with a 3047 pan head will support the thing, but it is 
very subject to vibration when focusing and such.

So, I'm wondering what needs replacing to help reduce the vibration?  The 
whole thing, or just the head or legs?

Thx

Don
