To put the rotisserie system together I used:
- a rotisserie kit, in my case from Lowe's, because they were convenient to where I live and was inexpensive:http://goo.gl/WsGbO
- an angle iron perforated; http://goo.gl/PP5Kn
I cut two pieces from it; one was 2/3 of the total length and the other one 1/3. I took the 2/3 of the length piece, cut it half way and bent it to create a square L shape angle.
I took the other piece and cut it at one end so it is a round shape so the end of the spike could rest on it. I then bolted the other end to have it shout out from the L shape.
I took half a brick and attached it to the metal structure with metal wire.
See first photo, piece at the end of rotisserie.
I am currently traveling and will put more pictures when I return next week.
The motor of the rotisserie is just screwed to a piece of wood and raised with a brick or two outside of the oven.
The nice thing with the FGM oven is that the people on the door allow to have the rotisserie turning with the door almost closed to keep the heat in.
Let me know if you need more details or have more questions.
