Re: atlas 10" quick change tool post
The major advantage to the Van Norman style QCTP? is that it can be made on the lathe. No milling machine? or even milling attachment required. Useful, yes, but not required. ;) The Aloris style is quite complicated, and requires a well-equipped shop & a skilled metalworker. I'm closer to that now than I was in 2015... :) Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first.

Re: Unbranded 10in. Steady rest
开云体育It also appears curious that the 1941 catalog photo shows a steady rest with no cast in casting numbers??? ?Perhaps the early versions did not have the casting numbers ?Ray On Oct 22, 2024, at 5:19?AM, mondosmetals <jwrey@...> wrote:

Re: atlas 10" quick change tool post
How about making a milling attachment for your own lathe? Or making/buying a milling machine... OK. Yes, my addiction is showing! Hi! My name is Bill, and I'm a toolohaulic! Bill in OKC? William R.

Re: atlas 10" quick change tool post
True that, but you can make one of them, yourself, too. Probably easier to make a Van Norman style QCTP. Check out one (or all) of the Mini-lathe groups. The QTCPs for the 7x?? Mini-lathes are a bit small for the Atlas 10" lathes, but can be scaled up fairly easily. Or just blocked up to center height.? Bill in OKC? William R. Meyers, MSgt, USAF(Ret.)

thanks for the replies

@ Bill unfortunately the original lantern style post got lost years ago i assume and being in the uk trying to source one on ebay etc is expensive by the time postage is factored in.

@ Ion thanks i will see if i can source one of those over here

12 commercial quick change gear box
Will a 12 inch commercial quick change gear box? fit a non commercial 12 craftsman lathe.? I think the commercial ways are 1/8 inch thicker than my regular lathe ways. My did not come with any change gears and I am thinking of a quick change? for the convenience factor. |
Re: Acessories for sale
开云体育Of course. We all scrounge for parts for these old lathes. Nobody minds getting an early crack at an item, before ebay. As long as you don't spam the list, you're good.

Just checking, i have accessories left over from selling my lathe. My question is can i list them here for sale instead of Ebay? I saw the for sale forum and the last thing listed was in 2018. I just don’t want to ?cause problems.?

Non factory 10in. Steady rest
I have a 10in. Steady that i have had for 30years and when i decided to sell it i discovered it didn’t have casting numbers on it. Has anyone seen these before. The casting is clean and looks factory and nothing like a chinese casting and fits the bed like a glove. Anybody else have info on this steady?

Re: atlas 10" quick change tool post
开云体育??? All of the 4 ways like in yer pic? that I have seen & used have? ball detentes in the bottom so the tool post moves in increments & is it's square on one side if ya use the detentes?? , ya may flip yers over & see if it's missing the ball & spring or if it even had one . It should be square for the other 3 sides . If ya have a 123 block , squaring up the tool post is a breeze . I just put it between the tool post & chuck & run the carriage up with the tool pose slightly loose , it will square itself & then ya tighten the tool post . My QCTP is a wedge type & I got it at either CDCO tools or CME tools , good quality & the price was good . With ya being over the pond I'm guessing that freight will be a matter . I have bought from Chronos in the past , I know they have them . animal On 10/21/24 4:41 AM,

A machinist would not be able to buy the steel for the AXA tool holders, for the price of buying them ready made. You would also need to buy the set screws, the long screw, and the two height stop knobs. And the commercial ones are also heat treated (well,
some of them, anyway).?
Go to eBay and buy your tool bit holders for 10-12 bucks a pop and rejoyce.?
