Some new mods to my HG/BM setup!
PeteH
I have a HG/BM setup I have been using for quite awhile and decided to hook the heating element in it back up. I hooked it up through a separate switch with a pilot lamp on it. My reason for doing this is to be able to preheat the bread pan and also add about 500 watts of heat to the outside of the BM pan during the roast.

I have always been limited to about 1# roasts because I couldn't roast more than that in a decent time. After hooking the heater in the BM back up I stuck a stem thermometer between the BM pan and the outer wall and preheated the pan to about 350f then put the beans in and maintained the temp on the stem thermometer at 350 to 400. I was afraid to let it get too hot as the thermal limit switch in the motor could open up. I think if I had some high quality insulation about 3/4" thick to go between the outer housing and the outer case I wouldn't have to worry about the heat getting to the motor.

Bottom line: I roasted 22oz of Guat-Cobian with no problem, could have done more. It hit 350 in 8 minutes, I backed it off a bit and it hit FC (405) at 10 minutes, I pulled it at 425 at 15 minutes. Hopefully it will be a good roast with that much time between FC and SC. I think the BM heater will hep give it more of a convection roast profile.

I also roasted 1# of Seedlings Ethopian Sidamo with this setup in about 12 minutes. I pulled it about 420, a nice City Roast.

I have a new 1800 watt HG from Grizzly.com ($19.95) that has an adjustable output and I know it would do 2# easily if it were cranked up and the BM heating coil going also. My voltage runs about 119v and the HG is pulling about 1620 watts wide open. 1620 + 500 + 2120 watts of roasting power, I love it.

The beans were in my cold shop and started off about 45f, that probably slowed things up a bit. When I read about paying $300 for a roaster that will do 1# it makes me like my setup even more.

Has anyone else tried a BM/HG roaster with the BM heating element hooked up?

I hope this doesn't seem like a run on post. :)
