Wearever 72000 Pumper question
Ah, the pumper. I have a couple. I like the upper part that is easily held on to while roasting. I modified mine with a fan-always-on switch and a second heat switch. I removed thermostat, and kept the thermo fuse in. One day I blew the thermo fuse and removed it. But I'm thinking of wiring in a resettable thermo fuse.

Others have posted instructions for wiring. Make sure you use appliance wire if you're wiring inside the heater unit. Also, don't use solder. It will melt and throw lead into your beans (I learned this the hard way). Learn how to use clips to make your connections. Not difficult, and quicker, and neater.

I use a soup can chimney with dial thermo punched in. To control the air flow, I attached a piece of card board to the end of my stiring stick. Works great.

One thing: I'm learning to control the air better. Before, I tipped the roaster to the side a bit to let air flow out. But now I think this dries out the beans too much, or oxidizes them too mcuh. Now, the roaster is nearly vertical, creating a fluid motion in the beans that I stir with the stirring stick. It reminds me of a roasting chamber now.

Good luck,
