I am in the process of making my own drying motor set up for use on drying. I am also trying to keep this to an inexpensive project since I will only be using it occasionally (I have thought about purchasing the components, but would rather have the satisfaction of building my own). My problem is with the chuck. I am planning on using a BBQ rotisserie motor I have and using a PVC end cap as the chuck housing. I am having a hard time figuring out how to attach the PVC to the 5/16" square stock that is needed in couple with the motor. I am probably making this more difficult than it is, but I cannot see the simple method. Should I maybe use something else instead of PVC? I looked through the galleries, and see the ideas, but can't tell from the pictures the details I think I am needing. Any help would be appreciated.

bob I have done numerous ones in this method, and I just drill a hole the same size in the pvc cap, and press the pvc cap on the shaft and use rod bond and have yet ot have one let loose. good luck

one of my first Dryers was a BBQ motor carved a wood dowel to fit the hole used a couple nuts and Epoxy to hold PVC cap

I drilled a hole in the pvc then rod bonded a plastic sheetrock / wall anchor big enough to insert the motor shaft in the hole. That gave me a longer "arbor" to fit over the shaft. Probably not needed but I then drilled a hole through the shaft and wall anchor and put a cotter pin in. That way it is easy to remove the chuck if you ever need to replace the motor.....

Drill out and tap the shaft for a sheet metal screw. Buy a 2" diameter PVC cap with a flat surface (not domed). Drill a hole through the center of the cap, and screw in place (with a flat washer if needed). I get the 2" flat PVC caps at Sears Hardware. Can't find them at Home Depot or Lowe's. Theirs are all domed. Good luck.

I drilled a 3/8 hole in the center of the PVC cap. Now, take a 3/8 bolt (about 2" long)and drop a "toothed" washer down the shaft. Now drop the bold and washer into the cap hole from the inside going out. Now add another toothed washer and a nut and tighten everything together. The toothed washers bite into the PVC. Now you need to get the 3/8 bolt into the square shaft of the BBQ motor. Take a flat file and file the end of the bolt square till it fits (forcefully) into the square shaft.
I have a couple made this way and they have worked for 25 years.

I want to thank everyone for helping me on this one. I was able to make the chuck using the PVC cap and using a piece of 5/16 key stock that I had one of our mechanics here at work press into the cap after drilling of course. I havne;t tried it yetm but it looks sturdy enough to spin a rod. I think I will add a bit of epoxy to it just to make sure.

Hey use a piece of fome from a rod. cut it on both sides 3/4 of the way down to that u have like a duck bill.
then u take the end u didnt cut and tighten it down on your motor. Now all u need is a rode strap. Put the rod in the duck bill u just made and tighten down with the rod strap
works so well would recomend it greatly
