Topic: veering into drum materials (was: careening into roasting (8 msgs / 136 lines)
1) From: AlChemist John
I was checking local sources of various materials for making my drum out 
of.  I was getting pricing on a both  24g 302 SS and "blue stove pipe".  I 
got a reasonable estimate for the 302 SS, but after determining what I was 
going to use it for, the gentleman HIGHLY advised against using anything 
other than food grade stainless steel (i.e. 302 SS) for a  roasting drum 
due to the possibility of unknown metal contaminants.  I had originally 
hoped (and still do) to find a less expensive alternative, but not knowing 
the metal constituent of "other" metals is a bit worrisome.
I know Jim G. has used brass perf plate (which I now have), and aluminum is 
usable as it is in most poppers, but does anyone have thoughts about other 
materials (metals) to use that would be safe?

Will let you know.  BTW, how much does yours (10x23) hold pound wise.
Also, my present quote is for 24 gauge, but you have 18 and 16 
gauge.  Quite  a bit stouter.  Should the 24 be durable enough or might I 
consider a  thicker gauge?

Any specific concerns or just gut feelings?

Only a few on the bottom for air flow.  Otherwise, I am using a solid drum 
in my design.

I know it is a bear.  That is why (mainly) I would like to find an 
alternative material, so that this novice metal worker has SOME chance of 
actually finishing the project.  Regardless, even if I do go with the SS, 
stove pipe my be my prototype for design.

Where do you find and/or would I find the reinforced cutoff wheels and 
stones.  The only ones I have are used up just cutting the top off a soup 
can (FR mod).  Otherwise, I have the rest of those tools.  Cool.  Opps, I 
don't have a bench grinder.  How critical is that/what do you use it for?

Well, I won't hold my breath, but I may well take a piece to the lab and 
check it for the major metals.  Cu, Pb and Zn are easy.  On that note, say 
it is not coated, and just a steel, even if that steel mixture has other 
metal, should they come out (i.e. vaporize) during roasting or stay in matrix?

That is all good to know. I was hopeful, but I too tend to err on the side 
of caution.
