Atlas Lathe Dial upgrade Pt2
Okay, So Im 99% done.
here are the dials installed along with the crossfeed index plate.
FWiW I have a few drawings for the compound back plate. DWG and my G code file.
Also Somewhere I have the drawings for the dials themselves.
I wanted to just order the dial setup from Jan over at TallGrassTools. he has some great tools
It would have saved me tons of time. But since I had already altered my dials with the thrust bearings.
I had to re think my strategy. And since my modification was not really reversible. I persevered with my current setup.
I did have some challenges with the 4th axis. I managed to get it setup as a true A axis and along with my g code I tried CNCWrapper. while it claimed to convert the code. I spent hours trying to get it just right. finally I threw in the towel and decide to trick the 4th axis as a Y axis.
Going back to my first G code. I calibrated the 4th axis in Mach3 did a few test passes.
it was accurate to .001 every test. I cut 3 dials. (1 as a spare) I could not have been more pleased.
I will admit I feel a bit of failure not getting the axis to perform as a true “A/ 4th axis”.
But the show must go on.
Ill add possibly some brass thumb screws as lock instead of reaching for the allen wrench. But Ill have to scavenge up a piece for that.
If you have a Atlas lathe? this upgrade is a must imho.
are these still for sale i cant seem to find them on ebay anymore
Dennis,
Currently no. I have on my list of things to do… Build another 100 sets. 1.5″ Im not sure If I’ll do the 2″ ones. If you care to I can let you know when they will be done . As Ill built them first then list on eBay. this way you can get em as soon as they are done. -Sam
