Use a spring ( about 4mm dia ) to go over the wire sections that spin

This may work but I think one of the issues with a sifter is this. As the curved rods rotate toward the screen, the clearance between the rods and the structure decrease to the point where the beans get hung up in between and bind. I had that occur when I experimented with it years ago and seemed to be a tough one to get around. Maybe raising the rotating element up a bit and installing the springs would allow a less rigid wiping action and prevent binding?

What kind of collars are you using for agitator ?
Are they part of the original sifter, or a DIY job ?
I would drill a hole in the collar, thread it and use an imbus screw to secure the collar to the axle.
As are this pieces:

I think KK was suggesting to get springs large enough to slip over the metal arms of the agitator. I did this with my early turbo roaster and it helped. I got them from McMaster-Carr and I think they were stainless.

The photo below was from 2011 when I built my first roaster. I used stainless steel welding rod with stainless steel springs over it. The added springs kept the beans from getting stuck under the paddles.

The suggestion would be to wrap the half circle arms of the agitator, I roughly sketched over the areas recommended to wrap with a spring. The springs allow for some forgiveness between the mesh and the agitation arms.

Looks like there's a lip there at the rim which catches beans?

If that is the case, can it be hammered flat all the way around?

135g of natural yirgacheffe in.
Dry stage seemed quite uneven, and I could tell the roast was taking too long. Dry end around 7 min.
No cracks for quite some time. I put the Poppery II lid on top of the sifter to retain heat. Still no cracks at about 16:30, so I dumped the beans into the popper.
1C began shortly thereafter, and was quite short. About 1:20.
Drop not long after 1C end (we're talking upwards of 19min at this point).
116g out, 14% loss.

I wish the old Sweet maria's thread was still accessible. Wonder why it was removed. I've heard poppers were used with flour sifters, though. I'm sure it would be useful to hear what they did.

This weekend I attempted to use a poppery 1 heat/fan unit as the heat source on my KKTO style setup.

Any chance to see a picture of this setup, you made me curious

Judging strictly by numbers, 600 grams shouldn't be too much for 1200W of a typical popper... a full size TO do this job with 1300 W... but different heat transfer, indeed...

I believe the poppery 1 is 1500w so I figured it would have no problem supplying enough heat. I have torn the lid apart already to either modify it to fit a heat gun or allow the poppery 1 unit to sit lower in the lid, closer to the bean mass. I'll try to paint a picture of how it was setup though, stainless steel cut to fit over the kkto pots. One hole with a hinged lid for bean loading and viewing and another hole big enough for the poppery 1 with the plastic portion of the popcorn chamber removed, just the bottom fan section and metal mixing/heating element section bolted to the lid blowing in.

Interesting... but there is still the popper noise, much more than the almost complete silence of a TO lid, so I wonder what is the catch, other than trying something different, for the love of tinkering
