My first 2 attempts were the Jet stand handles: 12” long solid steel rods that were somewhat rusty. They came out with only blackness on them. My 3rd attempt was something larger: the rusted infeed roller. After 24hours of cooking, only the end tips were free of rust, but the chipper looking waves in the middle section of the roller itself looked as if nothing changed with the rust. I did notice when firing up the battery charger, only the ends had bubbles streaming off, but nowhere in the middle section. This is one big solid piece about 2” thick. I did use 12 gauge copper wire to hold this part suspended in 10 gallons with 10 tablespoons of washing soda.
This weekend, I’ll be switching everything to steel to suspend the part and fine tuning my copper wire around the outside connecting the 4×24” rebar i sticks I used. Might swap the 24” rebar to the 12” rebar I used on the smaller 3 gallon container I used for the Jet handles.
