Thanks for the addition to the group. Seriously considering building a drum roaster along the lines of oldgrumpus's. Love the design and craftsmanship.

Electric Burners
Ringo
Alled Kenco sent me a catalog yesterday, I saw this burner kit in it. Looks sweet for a drum roaster, fan would be too small for an air roaster. Lots of BTU.http://www.allied...ts_id/1907

Sweet setup, but kind of expensive... awesome website resource too!

I think that for much less money you could make your own heater using coiled nichrome wire and you'd know that it would work.

Any good direction to learn more about that route? I'm feeling constrained by what is commercially available.

Go to Infrared Heaters at http://www.infrar...aters.com/. From there click on "Metal", then "10' NiCr coil heaters". Browse the website for useful design information like the tables. Also check out the Accessories page for heat resistant wire, terminals, insulation, and ceramic items.

For my 110VAC heater I used 6.75" piece of 19ga NiCr coiled wire. Then, I stretched it until the space between the wire was three times its thickness (or more); this is important. This bare wire will last about 2 years in my usage. Pretty cheap and easy to replace. The ceramic terminal block is useful to connect the heater to wiring.

I see why my post seemed expensive, thats a great link. The little insulators are hard to find, that place is tinkers heaven. That will go into my bookmarks, may build an electric roaster some day.

Yeh, I think that my replacement heaters are about $2 each! I like the 1/4" ceramic paper insulation, too. It's really more like felt than paper.
seedlings
Can that ceramic insulation come in direct contact with nichrome at operating temperature?

Probably, but I'd leave an air space. The heaters will last longer if there isn't any cold or hot spots.
