Knowledge is power the more long winded the better explanationsI started out with an old bar-b-Q grill that we stopped or just didn't use anymore and an aluminum heat press plate. but I could not get the controls to work the heat plate so I changed to a whirlpool range controls oven chamber and existing heating element. all the parts for it were reused on the side and inside the grill. as far as the conveyor rotisserie motor I got a ace hardware 1 1/4 pcv cut at 25 inches (4 sections) caps drilled in the center and plastic washers used in the center to allow them to roll.
Attached the rotisserie to a 2x4 drilled a hole through it for the shaft that came in two sections. ( how to get it to hold and torque to turn the pcv about drove me nuts.) it also came with attachable skewers.
I heated up the skewers and drove them through the side of the pvc then cut a hole in the side of placed it inside slid the rod through the skewer tighted it down and it turned.
I added a really thick black foam to the drive will that not only covered the hole but added great gip to the aluminum screed that I used for the belt.
I got ahead of myself.
Regular metal screen from home depot. was 36 inches cut it to 24 and used gorilla tape down both sides. no real info on how much of the adhesive to use so I just put enough to hold it together.
Did not add adjusters the screen goes slow enough not to off track and the extra pad that's on both the drive and end roller allow for pretty good torque.
The bottom of the grill is still there but I added ceramic tile to line it with.
the wiring and controls all came from the range however I did have to add an oven connection and a dryer connection to an 10 amp extension cord. all three bought at lowes. the oven works as far as heating up and coming on the belt runs from start to finish through the oven close to 5 min. although I have not gotten the materials to test to see if it will cure. that's pretty much it. sorry for being long winded its basically the diy conveyors that everyone else has made with a stoved and backyard grill.
