Wow! that sounds like a lot of work. I would have to get stainless steel mesh, a thermometer, figure out how to keep my oven open and then have 12 hours to watch drying potatoes!
I was checking ebay and there are some cheap Roncoe dehydrators on there..might just order one for less than $20 and give it a go.
Thanks for the info though...I will probably end up doing it because I am too impatient to wait for a shipment from an ebay seller.
Let me know how it goes with the smoker...
