Ok... here's my entry for "gerry-rigged":
I came across an offer for a free conveyor dryer. It started out life as an 11 foot long, 9000 watt dryer. The mercury contactor failed so the dryer was non-functional and the owner wanted it "gone".
I couldn't make an 11' dryer work.. so I literally cut a 3' slice out of the the dryer to shorten it to 8' long. I spliced the sheetmetal with flatstock and screws. The old base was useless, so I made a wooden rolling base to match the new length.
I reduced the number of heat panels from 3 to 2 (9000 watt to 6000 watt) and kept one of the two air bar fans in service.
My work-around for the failed mercury contactor was a $35 PID controller and 2 solid state relays ($20/ea).
The belt was in good condition, so I cut about 6' of length out and spliced the belt with teflon thread to make it work for the new (shorter) length.
I didn't put much effort it to finish ( a $4 can of black spraypaint). I probably had about 30 hours of time in the project... so you could make the case that my time would have better been spent printing (earning). Live and learn.
