Educate me on rotary tumbling with steel pins please

pro how did you find a motor where the shaft fit perfectly in the wheel? Or did you do something else?

It looks like the wheel is just turned by fiction from the shaft....doesn't look like they are attached.

I have a timer on mine but could easily do without it.

OK then where do I find a motor with a totally circular shaft? Or do I not need one?

I am looking at this motor

But the shaft isn't round, does that matter for the friction against the wheel?

I wouldn't think that flat spot would make a difference, most motors will come with a sleeve to bush the shaft to 5/8 but I don't think it's going to matter.

Also, I just use a media separator from Frankford Arsenal. I tumble, rinse the surface soap and water in the canister, pour about half(on a full load) of the brass and pins into the media separator and give it a slow spin. This gets out the pins then I rinse the FA separator again to clean the rest of the soap off the brass, spin one more time to get off water and go through a towel or two with a final dry overnight. Oh and I use a simple magnet to pick up whatever pins spill out during the spin process.

here's the link to the thread I posted a year or so ago about my foray into stainless tumbling on the cheap...

OK almost done. Two last dumb questions. 1. When doing the rollerblade method do you guys have something mounted to the end of the shaft for better traction against the wheel, if so what? 2. What size steel media are you using? And where did you order it from online?

the motor shafts are all gonna have a flat spot. I move the motor in till the flat is contacting semi firm and the rest is firm. keep in mind that the motor is going to turn continuous so it doesn't matter if it has a flat spot the motor is driving the shaft not vice versa. what ever pins you find will work. rollerblade wheels are semi soft rubbery so they handle the contact variance.

I got a good friend whos got a industrial elec motor rebuild shop. he hooked me up. I can ask him if hes got any more he'd sell if ya want
