????yes I think that it needs a bigger building, mine is only 20ft long. It takes up a lot of my room. |

Re: Collets questions
By the way. The guy I got it off of said it was a special order for his atlas lathe to turn tapered pool cues and longer items to short for his other lathes. I was actually contemplating cutting it down at one time but changed y mind. Sense I've never heard of a 8ft atlas before I thought that would be silly to cut on it. So one of these days if I get the funds I'll find a small bed for it. Or find a smaller bedded lathe and sell this one to save space. However I did make a drive shaft for a hay Bailer and a axle for small tractor o it all ready so that's a plus.?

Re: Collets questions
I would just use a mill bit to cut key ways in bar stock and wasn't planning on spending a lot of money on it but. If someone has a better cheaper way. I'm all ears? I'm think I would only cut no bigger than a 3/16key way ever and usually 1/8 keyway around twice a year so I really don't need a bunch of collets but if I could get a set for 100.00 I just thought that's a good price but. I didn't realize I had to get other stuff to actually use the I thought a collar to hold it in was it. But that's my bad for not checking it out first. Just got excited and jumped the gun a little. Thanks guys for all your help and if someone has all the stuff I need to cut a 1/8th keyway in a 3/4 bar stock then that would be great. Just let me know. Just wanna try to stay as safe as I can when I do stuff I'm not supposed to. As for my lathe it's coming along great once I get the I beam under it this week I'll post some more pics. Thanks guy for all the info

Re: Collets questions
The 10 inch Atlas and 12 inch Craftsman lathes used the 3at collet. There is an adapter that fits into the 3 morse taper headstock spindle for the collet. The spindle thread protector is there to remove the sleeve. A hollow tube w/handwheel was used to tighten the collet. This is what I use in my lathe! A 3c collet could be used with the supplied adapter. Southbend 9 and light 10 inch lathes used this system. You can find ER collet chucks that can be adapted for your needs. Thinking that a small six jaw chuck could be effective too, Steven. |

Re: Collets questions
Saw that too. Started drooling. ;) I'm wondering if he either has an old South Bend, or maybe Atlas did some special lathes... All I've ever seen is the 54" and 42" bed lathes. I understand there are also 36" beds, but I've never seen one. And only a couple of the 42's besides mine, and one 54". So not a lot of experience...

Re: Collets questions
I've got a functional chuck that I "built" from one made for the 7x mini-lathes. Still needs a bit of tweaking, as I got it to within .001", but not better. I also have the MT3 to ER-32 collet holder that I first bought, also for that 7x ML. It works nicely, but you can't pass longer stock through it. I have to practice cutting metric threads on my Atlas before I'm sure I can make my own, but I've got a couple of ER-32 nuts, as well. ;) Since I bought that, I've filled in the set of collets that came with the MT3 shanked collet holder, and bought another for MT2. Also MT2 & MT3 collets, and ER-25, and a some ER-11... You could say it's getting out of hand, and I'd not really be able to argue with you about it. :) Collet holders can come in handy, but a good 4-jaw chuck will do most everything they can do, just slower. I've been collecting stuff for MT3/MT2 lathes since 2008... I've also picked up stuff either in sets or individually, as and when they came available AND I had some spare money. There are a lot of paths to having a well-equipped lathe, and if you're a good machinist already, you can make much of the stuff yourself. I wasn't nearly that good when I started collecting. I have done some things to help me though. I have a stub arbor that matches the spindle threads on my TH42, which makes it easier to make stuff for the lathe. I don't have to pull the chuck off the lathe to test fit something I make for the lathe spindle. I need to get my lathe set up properly again. Which means I need to seal an MDF benchtop I laminated, and get it drilled and sealed again, then get the lathe and stuff all put together. And I can only dream of an 8' bed... Bill in OKC William R.

Re: Collets questions
开云体育You can make a temporary collet to hold a mill in a 3 or 4 jaw chuck to get your job done. Use aluminum. Very simple process.On 1/9/2024 12:39 AM, Billself wrote:
Thank you. I need a ways to hold bits so I can cut a keyway in a shaft.i don't own a mill yet so I've had to do it in drill press. Does work the best and it's really slow also you can see bit slipping once in a while. So wanna try the lathe method? |

Re: Collets questions
One thing you could do, figure out which thread the spindle on your lathe is, should be 1-1/2"-8tpi, and get a backplate and ER-32 collet chuck for it.? I bought one similar to this:??but with the 100mm flange, and put it on a 4" 1-1/2"-8tpi backplate for my TH42. If you're not a cheap bastrich like me, you could also buy this setup:? ? And you should look on both ebay and Amazon.com, as well as Victor Tool, CBCO Tool, and Shars. Better quality will cost you more, but if you know your way around your lathe, you can make as good or better yourself.? If you have the 10" or 12" Atlas or Craftsman lathe, they should be MT3 with the 1-1/2"-8tpi spindle thread, if it's a 6" I believe they're MT2 & 1"-8 (or maybe 1"-10) spindles.?
