Here's my 1-lb "soup can" style roaster. It's two 6" stovepipe caps with some stovepipe in between for a total length of 7". There are 6 aluminum vanes inside. That's 3/8" threaded rod, and the rod does attach to a second support on the inside (the steel of the cap alone can't support the load.) That's a Weber Chimney starter.
I had the drill, chimney starter, and wood...I just bought some parts at Lowes to make the drum. I set it on concrete in the yard. The roast is even but difficult to control outdoors. It's got a hole in the front for loading and unloading, but I still find it difficult to hear when first crack is done. I'm also using a different drill because the speed was impossible to control on the drill in the picture.

if you used charcoal you would get a more consistent burn every time. if you keep that constant then you can adjust the time for the level of roast. or dial the charcoal up or down. like with making espresso only change one variable at a time. that way you can replicate or more closely dial in your results.
ps if you want to skip the charcoal all together you could use a heat gun instead; but hearing 1c or 2c will be even harder. maybe propane torch?
