Many thanks for your input on this project. I really like the way you set up yours mounted under the table, but i will have to settle to have mine on top of the table.
Would you think a 1/2" threaded rod would work better than 3/8"'s. Because since I want to make the travel length for the crane 24" to 30" long since the GarGraves track in 36" long. I know on the motor end the rod will be supported well, but on the far end what can I use to support the rod so it will turn freely. I was thinking using a piece of wood to support the rod and putting a short piece of nylon sleeve over the rod with a nylon nut on the end. Then use a "U" shape clamp to hold it in place.
I would also think that I would have to use two (2) nuts attached to the base of the crane platform to move the crane so it will prevent it from shifting on the rails. I would have to use a piece of metal brace and drill a hole for the rod to pass through and use a very strong glue to attach the nut.
If I have overlooked anything please point it out.
