Both the heat diffuser and the lid are from Japanese dollar stores. They were originally designed as drop lids to use inside a cooking pot. (Holding down the food below the simmering liquid.) Finding the exact thing on amazon.com might be difficult. Amazon.co.jp: amzn.to/2VbW0zU
BEST OF LUCK! It's not that bad, but lots of minutia. Beater bar setup (hope this makes sense): Initial assembly outside of the sifter: 1. The beater shaft core is a piece of all thread. 2. Take a wire whisk and cut 2 wires off of that. (Cheap one will work okay, but you want spring steel for this part.) 3. Find the middle of the whisk wire and bend it 360 degrees around the beater shaft. Repeat for the other wire. 4. Put both wires on the beater shaft in the middle. Flange nuts only at this stage. Next you'll want each wire to form an "S" shape large enough to touch the bottom screen. You'll want nuts and flange nuts to secure these ends when final assembly happens. The basic shape should look like a 2D hourglass at this point. 5. Drill out the existing flour mixer holes and tightly fit steel spacers or bushings that will allow the beater shaft to pass through. These will keep the beater shaft from chewing on the flour sifter body. 6. Remove the wires from the beater shaft and the assembly/fitting fun begins! I used a series of flange nuts locked against a regular nut to keep things locked solidly in place, and this held up fine for about 2 years while using this roaster. Here's my assembly order: A. all thread on outside of the sifter, nut, long-splice nut for drill turning. B. spacer in side wall, nut, flange nut, end wires, flange nut, nut, open space to middle C. nut, flange nut, wires middle, flange nut, nut, open space to edge D. nut, flange nut, end wires, flange nut, nut, steel spacer in the side wall You have to assemble these things as you go along. I recommend to add the hardware in the order provided. Lock down the middle of the wires tight, leaving the edge hardware inner nuts loose. (You can tighten the outer edge nuts without problem.) 7. Once you get all the loose hardware in place you can then adjust the wire ends to match your sifter. I made my wires fit to the bottom screen solidly. Bend them in a "U" over the beater shaft. Once you have both wires on one end adjusted lock down the nuts, trim the wires if you care. Repeat for the other end. 8. A beater bar this tight will not work well in my opinion. You don't want the beater bar crushing beans and jamming against the beans and screen. Also it will cause alot of drag on the drill all at once when it hits the bottom. Loosen up the middle nuts. Twist the wire middle section about 90 degrees. This will give you a nice twisted hourglass design. Adjust the curve of the beater bar to be at least 1 bean away from the screen. This will let you use "beans to stir the beans." Lock down the nuts. Now it should turn fine. This will reduce the drag on your drill considerably. To test the stirring throw in some roasted coffee with a couple green coffee beans in and turn on the drill. Adjust the speed util you get a stirring action you like. Just watch for the greens and see how fast they move. It's alot of trial and error for assembly, but once you get it working it's pretty solid.
@@flactemnad legend! Thank you, I've had way too much trouble with the stock beater bars as they are to close to the side of the sifter. Thanks for the detailed info
Hi, collecting parts to create a sifter roaster and watching more videos for ideas. I like the idea of the foil-covered thermal blanket. So you have any details on what that insulation is and where to get it? Thanks - Frank
I used a "Carbonized Fiber Welding Blanket". Used for stove installations and welding protection. Should be able to find that on Amazon or welding supply shops.
Hey, thanks for the detailed video of your roaster. I'm following your thread over at homeroasters.org. Would love to see an actual roast video sometime.
Kind sir, where can I find that diffuser you use ? I cannot find it on Amazon ?

flacteMnaD thanks. ....I shall try my luck in some Asian stores ...
flacteMnaD I use claypot to roast coffee and want a good diffuser to spread the heat ...
Hey im looking to make a similar beater bar setup, can you please expand upon how you actually went about making that part of it?
BEST OF LUCK! It's not that bad, but lots of minutia.

Well done! -seedlings
Hey, thanks for the detailed video of your roaster. I'm following your thread over at homeroasters.org. Would love to see an actual roast video sometime.
Maybe next time I roast I'll remember to make a video. Need to include shots of the roasted beans too.
Great! And I love your use of the kitchen/cooking parts. My current roaster uses a flour sifter, milkshake jugs and a cocktail cup.
