Modding the AICOOK.BMH-1202A
HarryDog
This build is causing some issues, the cup I was going to use is thicker stainless steel and my cheap step bits wont cut it and the inside wall is too far from the bottom so I used a different cup much lighter that they would drill out the bottom and fits in the hole. During my hot and fast test the temp goes to 180c then drops to 150c so I need to bypass the thermal fuse by the look of it. I have already removed the plate on the cut off switch. During a 132gram test a few beans did fly out when green so it will require an extension.
I placed a short thermocoupler at the 100gram range, think this should have been lowered a bit? Going to bypass this thermal fuse and get a roast in.

Does anyone know of a good thread or two on a FB roaster using a heat gun, my next project?

Can't post a pic?
Pixel and file size is ok?

I think I found the issue, I stripped the data off the pic and it won't let me post them.

I liked the evenness of all three popcorn popper bean movement types, this one is slightly more even. I did have 2 half bean that did not roast enough but the rest were ok. Next I will test out that side plate to see how even it will roast, hope it will be even better.

I need to make a chaff filter as I don't think I will be able to use this roaster outside in the winter. I have looked at a cyclone but how much air flow is required?

Can I get away with using a 300 micron beer screen and just place it inside a vent tube to filter out the chaff without loosing to much air flow?
For small batches I think this will work.

300 microns is way too fine, will clog instantly, imo.
I would try a sieve with at least 500 microns opening (flour).

You can use the cyclone a lot of people here is using, the SN25T5 sold by chinese sites.
If happy to tinker, you can mock-up something very close from a cocktail shaker.

That looks like a good option, do any of the metal ones have a bottom flange?
That would be an easy way to just bolt on a jar lid. The plastic ones look to have a flange but not any of the metal ones I could find.

The beer screen is 2.7"x11.5" so I was hoping it would be large enough not to plug?

Nope, not delivered with a flange.
My approach is to make a custom flange from the jar lid itself, sealed to the cyclone with a thread of silicone.
The opening diameter is 40 mm.

Needed some fresh coffee so I roasted four batches at 150 grams each and the beans still moved well with the stock fan. Two just after first crack and two up to second crack. The bags mess up the light a bit.
