Hi! Looking for a legacy inlet temp sensor on 13 yr old Gene Cafe. It seems they've changed it and now you need new mother board and new sensor. Any ideas where I can find compatibile old one? Mark

peveleth, It is better if you start a post in the forum with your question. These shouts go away in time.

Hi Ralph,

This will be one fine looking roaster when you're done. We're all looking forward to some photos with some browned beans spilling out of the chute!

Thanks for sharing your progress. Great build. I'm happy to have found this thread. I have been toying with the idea of making a drum roaster.

What is the dimension of the gap between the rotating drum and the face plate on your machine?

It's really hard to measure it. So here's how the gap is set:

The main shaft that the drum is fastened-to can be adjusted back and forth. What ultimately holds it in place are set-screws in the bearings on the front and back of the machine. In my case, I turn the drum motor on, and with all the set-screws loose, I use a rawhide mallet to move the shaft forward a tiny bit at-a-time until it scrapes against the front plate. At that point I move it back until it stops scraping and tighten the front bearing set-screws. I leave the set-screws loose on the rear ent. That allows for thermal expansion to move things around without affecting much with regard to the drum gap. Does that help?

Ralph,

That helps out a lot. It is much appreciated. I just didn't know if there was a measured distance that you found worked well for your roaster.
