I am really green at metal fabrication and I built this without plans, just took my time and patience, looking at pictures of units online. 50% working on it, 50% thinking about it.
I used half the kit parts.
Now I think a kit is worthless if you can get metal from a yard and have some time. There are enough pictures of rotisseries online, you can build one by looking at pictures.
If you can set up a head rotator with a pipe that fits inside another pipe nicely and smoothly with minimal clearance, then square it to the horizontal arm and vertical slide, you are set.
The key is keeping all things square and parallel as possible so when it rotates, it has no binding or pressure.
