7/28/04 Rotisserie Construction Page 1 Page 2 Page 3 Page 4 Page 5 Page 6 Page 7 Page 8 Page 9 FINAL Update I ran into a problem when I went to build the rotating assembly, specifically the pin that fits inside the sleeve. That's why I haven't done an update for a while. When I bought the round tubing, the pin fit inside the sleeve easily. I believe the heat of welding must have distorted the sleeve to the point where the pin would not fit inside. I spent four days trying various ways of enlarging the sleeve, ranging from a cylinder hone to a sandpaper wheel to a diamond-tipped die grinder bit I borrowed from work. No dice. I couldn't believe how much the sleeve had changed size! Ultimately, I took the pins to work and had the guys in the machine shop take 0.030" off of each pin on the lathe. Result: perfect fit with a great surface for retaining lubricant grease.
I also used the sandpaper roll I purchased yesterday to smooth out the inner surfaces of the rotator sleeve to help it rotate properly. It left a really nice, smooth surface.
Then I drilled a hole on each side of the sleeve, one in front and one in the rear to supply grease to the rotating assembly. I tapped the hole to accept a grease zerk (1/4-28 threads, by the way). Overkill? Perhaps. But that's the way I do it. I did make one addition to the blueprint of the rotisserie, and that is a pair of triangular gussets that hold the rotating sleeve to the height-adjustment sleeve. I thought about how the round tubing was welded to the square tubing of the height-adjustment sleeve, and figured that some additional support would be a good idea, especially since I'd made the pin thinner by turning it on the lathe. Stronger is better in this case.
