Still type

[Sparky81]

I have 12 gallon copper wash tub style boiler, it has a brass screw top with a 90 degree fitting that necks down to a 3/4 compression fitting. It does not have a condensor.. What would be the best method cooling with this type boiler. I plan on adding a thumper (5 gallon). Should I use a standard worm for cooling? If so, what size copper would be best to use with a boiler of this size?

Is this type boiler any better or worse than a boiler with a larger condensors that tapper down from a 2 or 3" diameter to a 3/4 or 1/2' worm.

buy a lead test kit...chances are the solder on your boiler contains lead. I tried to use the same thing when I first started. When it tests positive decide if you're ok with that. the lead SHOULDN'T make it into the distillate so long as it's not in the vapor path...but after much thought it turns out I wasn't ok with ANY lead contact.

yes check for lead, if it turns out ok i use a 1/2 in. worm for my 10 gal. rig and it works fine. i have seen these tubs where all the soldering was on the outside and no solder at all on the inside. bad solder can be remelted and cleaned and replaced with some work.

Yes lead test is in order. If tests positive. All traces of lead should be removed before used as a still.

If you are adding a thumper? Run 3/4" into the thumper. Come out of the thumper with 3/4" then reduce to 1/2" for the worm or liebig. If not using a thumper either 3/4" or 1/2" will work.

Thanks guys, I will pick up a test kit today.

I have purchased and used two different brands lead testing kits. One from Home Depot and one from Wal Mart. They were the type you rub on a surface (seams and joints). There was no discoloration to inidicate lead. Do you think that is enough? Or should I do a plain water run and test the water using a liquid test kit?
