I don't have a lot to say about the machine right now.? Need some time to get it set up and running and I'll take a closer look at it and share my comments later.? ? ?

I must say from the pictures that machine looks to be in great shape not the usual abused , neglected and seriously rusted we have come to expect.? Is that original paint???? where is the oil stains???

Hi, ? Just got a new to me Atlas MFB mill.? ?Its serial number is 007449 and I would be thrilled to learn its date or approximateb date of manufacture. ? ? ? Thanks for any insights. ? -Rick

I agree with Andrei: get an inexpensive laser tach and eliminate the guesswork. I’ve been doing this for so long that I usually just “eyeball” the speed and take a test cut. Between my habits with grinding bits and a rough guess on the
belt combination I can usually find something that works. Still, the laser tach is useful to have around the shop.

Sure would be nice to see things built to last in these days .
Now a days if ya have something last more than a year or 2? folks
are tellin ya it's time to replace it .

great. Or, simply get jars that are of different diameters.
The larger the jar diameter, the slower the tumbling speed.?

Re: Atlas 10F motor step pulley, part 10-428
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 myself!

The laser is bounced of the tape after each rotation and there is a sensor inside the tachometer that counts those "pulses". That is how you get your RPM count.?
You could try polishing a small area, then if it fails to work, just put the tape over it.?
