i would definitely not do that. If you are using stoneware you can get away
with a mild steel barrel. If you are using porcelain/bmix/etc then you
should first check out any scrap yards around and see if you can find some
stainless pipe. It would be expensive but worth whatever the cost.
I built a harry davis-style pugmill and also a 500 lb batch clay mixer
several years ago when i was first starting out, and now i make my living
off that stuff. And i am really glad i did not cheap out on components even
though i was tempted to at times along the way.
Even if you have to buy a new piece of stainless pipe it would still be
worth it to do it right.

Subject: PVC Pugmill Barrel
To: Clayart@lsv.ceramics.org
Has anyone used PVC irrigation pipe for the barrel of a simple
non-deairing pugmill (similar to the one on the Lue Pottery site -
thanks to Des & Jan Howard & Roger & Pauline Graham). I am about to
build one of these & after reading all the possible problems with
barrels (& rusting is a huge problem here), i thought that the
irrigation pipe is fairly inert, very strong & comes in all shapes &
sizes, including reducers for the nozzle. The blades will be stainless
steel.
Any potential problems before I start & waste precious time & money??
Many thanks
Tracey
