Dear Karl -
What did the fish think about the wig head? Any takers?

Why not just make it out of foam- I took a Styrofoam wig head down 2000
feet and it's still got at least 1/3 of it's volume-and floats just
fine-
 how deep do you plan on going?  so what if the foam looses a bit - or
even half it's buoyancy- it will still do what you need- and can't
flood, rust or implode!



I was attempting to machine the pieces for a metal "bobber" for my new
soft 
ballast tank's water level indicator (Foam just gives at depth, so
that's no 
good). The piece is essentially one piece 1cm in diameter 1mm thick
walls 
and 1cm in length and another 5mm 1mm thick wall and 1cm in length tube
with 
two 1cm diameter 1mm thick "washer" end caps with a center bore hole of
5mm.

I can get the pieces machine out great, that's the easy part. I'm trying
to 
weld them all together however and I end up with some really shitty
looking 
welds. I've never attempted to weld something so "delicate" before. What
I'm 
trying to make here is a preasure proof bobber and the end product
should be 
something like a hollow bearing.

All my welding is done via stick arc welding.

Any suggestions?
