What to fill your tripod legs with......
Posted 24 July 2006 - 08:51 PM
I've got a decent tripod and a giro 2 mount...with a long refractor which
vibrates quite a bit .....8..10 seconds at worst.
What's the best thing to fill tripod legs with
I can get lead shot...or...I;ve had sand suggested as another posibility
What do you think?????

It's all reversible (other than the expanding foam perhaps). Try sand, then empty the legs and try lead shot if that doesn't work.

Another option to surpress virations is to hang a heavy weight from the middle of the tripod.

I might try sand...a Mate mentioned that rapping the leg
and listening the ring might give an idea of how
vibrations are dampened, although these are ringing at
1000 hz plus so I don't know how relevant the sound is
as the frequency I'm damping is probably much less than 20hz

Orion USA or the celestron ones

An ash tripod is better...
Ash is great at suppressing shock/vibration.
Its used to make hammer handles.
(Rots something terrible if its left damp!)

... as is expanding foam.
How does that work, I would have thought it lacked density?

It's not the density you need it's the anti vibration. The foam absorbs the energy and stops the resonance quickly.
Sorry - but from an engineering standpoint this is pooh. You need mass to absorb vibration. Fill your legs with foam and you get echos and harmonics.
