Atlas Refurb and Tooling

NOS is nice to have and sometimes original tooling is of better quality than what is coming from china.

If you want to add to your supply of holders you can look at Enco as well as others. It is almost impossible to get this to come up using Enco's search function.

Wholesale Tool has them for about half what Enco wants, one link is for carbide tool bits (zero back rake)

and the other link is for use with HSS / colbolt bits holder with positive rake (I thought it was negative rake, but they say positive in the ad.???)

I hope this helps,

Mike, thanks for the info. Here is a follow up question. The width of the slot in the tool post where the tool holder goes is .400 wide, does this mean that I would order the .375 or 3/8" wide tool holder and have a little wiggle room or would I stick a couple of feeler guage shims along side to tool holder. Does this play cause any problems?
 
You'll want 3/8" x 3/4" shank toolholders. 7/8" tall should fit, but 1" tall may be pushing it.
And, no, you don't shim the sides.

That Right-hand toolholder in the eBay ad is what works for facing cuts.
You'll need the other Left-hand toolholder for radius turning.
Those toolholders in the Wholesale Tools link sure look promising.
As far as bit size, 3/16" has been a little more difficult (for me anyway) to find versus the more common 1/4"...

Jamie,

I have 3 lantern (Rocker type) tool holders, the smallest has a width opening for the tool holder of 11/16". So it takes the next larger tool holder with the 3/8" tool bits. To use your current tool post you need the smallest tool holder. Wholesale tool also sells the tool posts ($29-$39) but I'd go with the smaller post and holders for your 6" Atlas.
No, you do not shim the sides of the holder to post and you won't have any problems with the little "wiggle" room.
When set, you'd be surprised at how rigid a setup you will get. The tool holder/bit isn't going anywhere. Just set your tool bit to Center Line of the work (not above center line or you can dig in and have bad results).

What size tool post do you have on the big lathe? Do you have the half moon rocker piece that goes between the dished out washer and tool holder? They tend to get lost.

So it took me all this time to figure out that a right hand tool is used to turn from right to left, but you would put this in a left hand holder. How counter intuitive is that?! Oh well the RH holder will get me started and once the Christmas spending for the kids passes. I will buy a LH and a straight.

I had a few minutes in the shop last night I removed the back gear from the headstock, and took apart the tailstock and the compound. I took plenty of pictures to keep tack of the little bits. Only thing left to do is the carriage and apron. Then I will degrease everything, strip if necessary, paint and reassemble. I have 2 weeks left of this semester at school. Then during the break between semesters. I hope to get the lathe up and running. Wish me luck. I will post more pics tomorrow.

Found this on lathes.co.uk looks like the motor pulley that i am trying to replace has diameters if 3-3/16" and 1-11/16". This should get me what I need to make a replacement. Now to find some suitable stock.

Boy, I swear, some of us just can't move as fast as we used to (or remember). Finally got out there to get pics for you.

My lathe is configured as an underdrive. Difficult to get to the motor pulley.

To get the motor pulley measurement, I cut an old tape measure and leaned it against the motor output shaft. Assuming minimal camera parallax, you should be able to derive the pulley dimensions (hopefully).

Thanks for the measurements that looks like about what I found. I think machining this out if 2011 should work nicely.
