Bobby M15's drum
BobbyS
The one on the front that is shown is a Spyraflo.

Edit: also on the back I have a contained 2 bolt bearing that I can lock the shaft with.

Getting a little more done. Here is the trier I just finished.

The handle I ordered from these folks. Was inexpensive and I received it fast. I used the larger handle as I wanted as much distance from the hot end as possible lol.

well, I was trying to post some pics but it won't post them for some reason. So, I will just make the url below clickable then.

With Jacks great help! Thank you!

Starting to make some headway finally. Got the cart started (with casters) which makes it so much easier to work on now that it is getting heavy.

With the bean hopper door in load position it covers the exhaust port so no beans get away.

Looking good. I'm liking that hopper-gate assembly!

Are these necessary to be SO massive... ?
Just puzzled... not critical.
I am asking myself this question every time I see a commercial roaster too, especially the small models, 1 kg seems close to 5 kg.

Nice work BobbyS!

It is about 2kg, probably do a bit more and looks bigger than it is. It is about 14 inches across. Also it needs room for the heat chamber around the drum (not on yet) and insulation.

Yeah, go big or go home lol BBQ grill

Thanks, I haven't tested it yet so we'll see how it works. Hopefully it will do well.

Lol, you and me both! Do you think 1" of space around the drum for the heat chamber will be enough? You can see where I marked it with a marker on the inside of the back plate.

1" should be fine. I went with 1/2" on my 1 lb drum trying to limit the total finished width but had some issues with the inner sheet metal layer warping and rubbing on the drum since I mistakenly left no room for the metal to expand in length (front to back). I should have left at least 1/32" gap.

How can it be attached if it moves with heat? I want to be able to keep insulation out of the heat chamber.

This is one of the more troublesome areas of a drum roaster design. The structural rods connecting the rear and front plates are necessarily rigid and do not expand/contract at the same rate as the inner liner since the two do not see the same temperatures. One option is to mount the shield using angle brackets with elongated holes and somewhat loosely attach with lock washers so the shield can move independently from the front and back plate assembly. You have to leave a little room between the plates and shield and insulation shouldn't fall through the crack.
