Re: Tumbler speeds
Oh, yes, this is a tank of a rotary tumbler. The base is either ? or 3/8 steel. It was bent to shape, not cut and welded. They must have used a big ass press to do that. The rollers are specially

Likewise! I've got a digital RPM gage, but it's a contact type. Also an old mechanical contact type that probably needs a bit of refurbishment. :) Lots of stuff around here like that, including

Re: Tumbler speeds
Sounds like? it was built to last . My first one , the one I built? I used? 2 3/4 rods with rubber hose I slid on in between 2 pillow blocks for each shaft mounted to a piece of thick? plywood?

For the 9 bucks it costs for a new laser tach, I'd say, just buy one and enjoy its accuracy. ________________________________ Sent: Tuesday, September 12, 2023 2:25 PM To: [email protected]

Re: Tumbler speeds
It has a single speed gearbox that I took off and put a belt with pulleys (that is all I had on hand). Last week I finally had the time (after 3 years) to clean out the gearbox and wash it off with

I have a pretty nice expensive hand tach , that's reflective or mechanical That only works on the mechanical side . I need to get inside it & see ifin I can find the problem . animal

Re: Tumbler speeds
Change belts on pulleys. Have not found a reason to do more. ________________________________ Sent: Tuesday, September 12, 2023 1:51 PM To: [email protected] <[email protected]>

Re: Atlas 10F motor step pulley, part 10-428
You can always try it, but I think that unless you can ensure the laser beam is reflected back within a few degrees of 0, you might not get any counts. The laser is bounced of the tape after each

Re: Tumbler speeds
I'm just curious , were ya planing on changing pulleys or a variable speed motor ? All of mine are just on/off , I never considered if I should be changing the speed of them . My first one the one I

Re: Atlas 10F motor step pulley, part 10-428
Please keep in mind that you will need to put a little reflecting tape on something that spins. that will reflect the laser beam back to the device to count RPMs. Try to put it on something that does

At that price I can't say no- thanks Andrei.

Re: Atlas 10F motor step pulley, part 10-428
Buy one of these photo tachometers. It will be more accurate than your calculations, as it measure actual RPM of the spindle.

Re: Atlas 10F motor step pulley, part 10-428
Motor companies make spacers to adapt half-inch shafts to 5/8" pulleys. You can make one, too! If you want to, anyway. They're usually bent/rolled from 1/16" steel sheet, but you can turn one out of

Re: Atlas 10F motor step pulley, part 10-428
Thanks Bill. My motor is a craftsman branded also with the 1/2 ID, but the prior owner replaced the step pulley with a single 2.5 OD pulley. I wanted to dust off the old math book and using the

Careful on the bore diameter. I believe my original is 1/2 ID to fit the 40s vintage motor.
