Hi,

I was one of many who answered the initial inquiry.  The problem with cheap
is that you have to build a complete solder pot with temperature controller
and all and you have to transfer the solder as a liquid for one pot to
another so the spare pot has to be portable (wheels?).  I've seen shops
scavenge an old pot from an old machine and use that.  One thing is weight
and insulation.  A solder pot can be relativly small but by the time you add
all the heaters (how fast do you want this to heat up (3hr, 12 hr, 24
hrs?)and the insulation to keep from pouring power into it, you have a
pretty big package.

Buying and shipping one to Malaysia (that's .my I think)is probably not
practical.  You might try you local machine/welding shop (can do in
Singapore I'm sure and probably in Penang and KL) to build you a basic pot
the slap strip heaters on the side and cover with insulation.  Drop a
thermocouple (IN A WELL!!!!!) inside the pot and connect to a temperature
controller.  You might also add an overtemperature switch to cut off power
if it gets too hot, they are cheap and a nice safety item.

The problem with solder is that it expands when it solidifies so if you drop
anything into the pot, not in a protective cover, it gets crushed eventually.

PS.  Warning the following could be consider commercial (kind-a)

It's not what I do now (used to be with Gyrex a looooong time ago), but if
5-10 of you are interested in building your own pots, I would be willing to
put together a (one time only) package with drawing for a pot to be built
locally with a set of bolt on strip heater with heat transfer compound, temp
controller, thermocouple and temp switch.  I'm not interested in doing it
for one as I'd have to charge too much to make it worth while.  I'm not
interested in doing the metal work and the components drop in a box and ship
UPS anywhere in a few days.

Can I get away with this?  To commercial?
