Plug Dryer Problem

[Swimmer]

Maybe the Professor can help with this. The el cheapo dryer setup I bought has a shaft that is 5/16's square. It comes in three pieces and when it turns I have the ugly feeling it wants to come apart. Is there such a thing as 5/16"s square stock that can be bought. Or barring that, is there 5/16 round stock that the end can be squared to 5/16's, so it fits in the dryer motor. The shaft now turns inside of sleeves that have set-screws in them, which I tighten against the 5/16's square stock. I like the overall job I did, and this has popped up as a lose end and is bugging me. I am going to PALCO plastics to buy some clear plastic to make the door with now, which is the last thing I need.

there will always be issues that pop up... 5/16 square stock is available..... I've also used some in the form of key way stock on some of our big exhaust blowers....
My rotissary motor had a 5/16 sqare drive ... that fit over the drive motor... I through bolted the drive to the motor, I turned the opposite end round ( 1/4") and fitted it with a flex coupling.. this solved alignment problems..... from there it's all belt driven..

for me.. I have as much fun building jigs and tools to aid the job as i do building plugs...

I cut mine off Roughly 6 inches long And then Cut a 3/8-16 thread into it Then I converted it to threaded rod With Rod coupling and two nuts I then put bushings anywhere it passes through the plug drier housing.

Where can you buy 5/16th square stock, preferably aluminum, to keep the weight and the workload down on the drive-motor?

homies and Lowes carry some of that stuff. If not I can look at work to see if we got any or I can make something to size. When you come over to get tool bring what you are trying to fix as I can't really understand what you are trying to achieve.

5/16 round should fit the 5/16 square motor coupling as is. Maybe file a flt to accept the set screw.

good gravy $27 a foot for alum key stock. I brought home a 4 foot piece and was going to tell him 5 bucks. He already remedied the situation. Probably just leave it down the cellar till I need a 100 bucks
