Thanks for the addition to the group. Seriously considering building a drum roaster along the lines of oldgrumpus's. Love the design and craftsmanship.

Part 11 - Sight glass
Alchemist
11. View of the beans: Set of pyrex watch glasses between a pair of jumbo washers. Held in place by magnets in the face of the roaster. Washers are ferrous. Magnets facilitate easy removal and cleaning as needed.

Quick drawing of the assembly and how it fits together.

I picked up a pair of jumbo washers as speced put above. They are without any holes so I test drilled one this weekend. As washers are supposedly meant to resist wear, I was a little fearful of how difficult they might be to drill.

Worries were unfounded. Freehand drilling with a good carbide tip and they drilled out just fine. This is a good to go sign.
