<< Earl,

 Been there, done that.....we 'drained' the molten solder into containers
 that would form the solder into sizeable chunks that could be 'dropped' into
 the new pot. It is the long way around, but it worked for us at the time.

 I am assuming the 'old' pot is heatable....if not......'never mind'!

Hi ya Earl!

     Yep, Richard tells ya' right...I've had to drain a pot once or twice, and
you just gotta heat the pot and drain it into some containers...pain in the
keester for sure, but the only way I know to do it. You might give your dross
recycler a call and see if they can provide you with some containers.

     That's what I did out here the last time I had to drain one, and they
were glad to bring me over some. What they might bring over looks like round,
gallon-sized, paper containers that kinda look like what ice cream would come
in. I was a little leery of draining molten solder into paper containers, but
if you lower your pot temps to just a little above liquidous, and don't fill
them too full, paper containers do just fine. If you fill them too full, it'll
retain the heat longer and the outside of the container will start turning a
"golden brown"...kinda' got my adrenelin going a bit the first time I saw
it...was worried that I was about to have a nice solder coating all over the
floor!

      As to why your pot got damaged, shipping the machine with a full pot of
solder is done all the time, but really it's not a normal way of shipping. If
the machine wasn't prepared correctly for shipping with a full pot or the van
line did a little "four wheeling" so to speak, a machine can get damaged
pretty easily with a full pot. Wave machines aren't made to move around with a
full pot.

      One place I worked at we had bought an Electrovert UltraPak with a full
pot, and when we were spotting it into where it was going to be installed, the
guy on the forklift sat the machine down a little quick...it didn't appear
that it was too quick that it would cause damage, but with the full pot the
frame of the machine wound-up being tweeked, and we had to ship the machine
back to the factory to get fixed, they couldn't do it in the field.

So, you might make sure nothing else got damaged besides the pots. On the
machine of ours the pot was fine, the frame was the only thing that got hurt.

Sounds like you got your hands full pardner!
