vince,
in discussing pugmill action, you wrote that you pug clay stiffer than
throwing or sculpting consistency. why? how do you wet it to throwing
consistency? with throwing slip on the wheelhead, or is there an
intermediate step?

Brian -
Whenever I have clay around which has stiffened up a bit, and I want to
return it to plastic consistency, I run it through the pugmill, first
dipping it in slurry or water. I just break up the clay into chunks and dip
each one before tossing it in the hopper. If I have thick slurry on hand, I
use that, because it REALLY boosts the plasticity. If not, I just dip them
in water. Even if the clay is only slightly on the stiff side of ideal I
dip the chunks in water before pugging them, because the vacuum action on
the deairing mill always removes some water, and I always try to avoid
working with stiff clay.

Hey Vince,
My new VPM20 has a little tube thingy hanging off the back that has water in
it. I don't think the water was there when it was delivered. Is this bad?
Also, the little gold filter on the vacuum pump spits water when it's on. I
am not a machine type really, so don't know if these two things are bad.
Yes, I do have the little book that came with it, and have looked through it
for instructions on operation, but the tube thingy is not part of the
pugging process.
Thanks! :)
PS: your workshop is full and people are STILL calling to get in.....have
6+ on the wait list.

Not Vince, but here goes
If the "little tube thingy" has a valve on the bottom open it to let the
water out...this is a dryer that acts like the ones on a compressor line. I
am assuming that this is on the line to the vacuum pump...right? if so and
the dryer is full of water then the excess water is getting to the pump and
being expelled from the outlet there.
If there is no valve on the bottom of the dryer, then give it a twist one
way or the other , and the body should separate allowing it to be emptied.
Tommy

Lisa -
This is something you should take up with the pugmill manufacturer. I do
not have any idea what the "thingy" is that you refer to. But your vacuum
pump should NOT be spitting water, because the water should never get in the
vacuum pump. It might be necessary to put in a water separator between the
pugmill and the vacuum pump, but you need to talk to the manufacturer about
it.
Good luck -
