Which is better a metal or plastic processor any why?

Metal is better. It wont melt if heater controls fail. plastic will, and lead to a meltdown further fueling flames.

where could i buy a metal tank or are there any plans how to build one?

it depends on the capacity you are looking for. there are prefabbed cones for 25-55 gallon drums. you can have a weld shop make you a cone tank, buy the size cone tank you want($$$)or use a waterheater sized to your needs

You can get metal processor plans on my website.

Best plans on the internet.!

If you live near Memphis, I could hook you up on a metal tank.

And if you had your location in your profile, we all would know who is the closest to help you.

Propane tanks are strong and sealable. They have to be re-tested every 10years. The local re-test centre will have tanks either free or at scrap metal prices. I aquired one recently perfect condition except for a dent on the shoulder. They have a concave bottom for easy draining.

What size tank, Dave?

There is a discussion about "the new appleseed"

I assume there is also a discussion about the old appleseed.... somewhere.
