Question about a spray booth ...

What are the dimensions of the booth? also what size lumber are you using for the internal frame work? Thank you for your time!

I cannot help with much but add that I was looking at one not long ago that was driven by a single motor with belt and pully to each level but cannot recall how the butt and joint end were held in place, you might be able to find an inexpensive live center for one end to make it work.

Booth

I spray my butt and shaft joined. On the butt end I tap them all for a threaded bumper or weight bolt, same threads either way. I just use a piece of 3/8-16 bolt into the threaded butt to turn/drive it with a variable speed motor. Not sure if that hits your question or not.

This is what I made for my booth. I have a delrin piece on the motor that has a .5" nub with a flatspot, then I made a series of delrin mandrels that are tapped for 3/8-10, 5/16-14 and 18, radial, etc. They have a threaded hole that a thumbscrew goes into to tighten on the flat spot. If doing a shaft, I thread in a small piece of threaded rod, if doing the butt, I remove the threaded rod and just screw the mandrel onto the Joint Pin. On the other end, I use a Taig mini live center that is spring loaded, that the point can be removed, and I made other delrin pieces to fit whatever I need on that end, like a concave tip holder, a large center for a end of the butt that has a hole, or a house cue type with just a center hole.
Hope this helps.

Maybe some of this will help.

There are two bearings for each center, centers are made from matching diameter bearing rod. Pulleys are made from delrin and press it on. Delrin stops and set screws to fix the drive side and created adjustable spring tension. Cheap gear motor, drive pulley larger to get the rpm where I wanted it. Belts are cheap O rings.

Very Nice Kelly.

Thanks.........

Very nice Kelly. What blower motor is that you are using? I have been working one one myself and have a furnace blower but it is direct drive and started having second thoughts. Looks like yours may be direct drive too.

Thanks. It is a Dayton blower motor I bought like new off eBay for a ridiculous price compared to what it lists for. Relatively high CFM for the application.

A dead center with enough spring pressure is all you need to drive it.
