List Etiquette (Was RE: HSS Indexable Inserts (Was RE: [atlas-craftsman IO] Atlas Craftsman 3950 back gear question
¿ªÔÆÌåÓý? ? ? ? ? ? ? I realize that it saves time to just hit the Reply button instead of typing in an address and I know that I sometimes forget to do it myself until about half a second after I hit SEND.?

I realize that the subject of Subjects has nothing to do with either HSS Inserts or 3950¡¯s but left them for the purpose of this post as examples of how to politely change subjects. ? On this list, there are two reasons for doing this.? (1) Don¡¯t do it and you are guilty of thread hijacking.? (2) For the relatively few people who read the mail online instead of downloading it to read, finding something later is difficult as the latter part of the thread will have nothing to do with the thread subject. ?

Re: Faceplate & Dogs
¿ªÔÆÌåÓýJody , ? If I am reading you correctly this is actually two separate issues . . . . ? ? For driving a workpiece between centres the lathe dog is fine and a 6¡± faceplate is a convenient way to engage it . . . just a tip if the dog engages in a slot in the faceplate just wire it with a bit of baling wire or pack it with a shim to stop it rattling while you are turning which might otherwise spoil your finish . . . ? Carvel ? From: [email protected] [mailto:[email protected]] On Behalf Of Jody ? I'm needing tooling for turning between centers and sparked a couple of questions.? My lathe is 12x24 101.07403 |

I'm needing tooling for turning between centers and sparked a couple of questions.? My lathe is 12x24 101.07403 1)? Should I pay a little more and get the 8" faceplate instead of 6" 2) Do you guys like other methods other than using the typical lathe dogs or is the drive pin threaded in the faceplate a better setup?? what do you guys prefer? Thanks, Jody |

¿ªÔÆÌåÓýI go to the N.A.M.E.S. show here in Michigan. They are always there and offer discounts. I agree their holders are expensive, but they are nice, but the inserts are reasonable.

Kind of expensive IMO, but if you are looking for high speed steel rather than carbide, and are put off by freehand grinding your tool bits, this may be worth considering. ? Contact Arthur R Warner Co. ?Latrobe, Pa ?723 539 9229. ?This contact info is rather dated, and if no longer valid, their website is listed ?as . Hope this is helpful. ? |

Re: Atlas Craftsman 3950 back gear question

It came with a decent amount of options and a lot of 1/4" tooling blanks. Some looked like they had been ground to test certain shapes. I will look through them again and see if there are any I can use immediately.
I will eventually be grinding my own as I have read that the HSS tooling works better on this size lathe, as you have stated. As a complete novice I am saving the tool grinding for stage two of my journey into the world of lathes, hence my choice of the carbide tools. The QC will take 3/8" tooling but the seller recommended 1/4" carbide tooling for light work -- which is what I will be doing to begin with. As to the email...I get the posts in bulk and don't have the option of hovering over the sender. If you can email me at the above email, assuming you can see it, I would appreciate it. Thanks again, Dan |

Atlas Craftsman 3950 back gear question
#10d-260
Dan How well equiped is your lathe?? The Atlas lathe manual isn't specific to your lathe but has a lot of good info in it. Depending your experience and what you expect to do with your lathe you might find that HSS steel cutters will work better in your lathe.? The down-side is you'll need to learn to grind them.? The plus side is the're?a lot cheaper. The add for your QC looks like it takes 1/4 or 5/16 tooling, but does'nt say so.? My experience is that unless you buy expensive carbide inserts, they are not very sharp.? Also carbide has to be run a LOT faster to give any sort of decent finish, even when sharp.?? If you hold your cursor over my "FROM" name it should give you my e-mail.?? Have a good evening Jack |

Re: Atlas Craftsman 3950 back gear question

Jack,
I do have a copy of the Operating Manual and I also picked up The Atlas Lathe Manual for background. I am waiting for some CRC Extreme Duty Open Gear and Chain Lube that someone on one of the other sites recommended for the gears. I am going to give that a try. I just ordered a tool post off of Ebay () that seems to be very similar, only cheaper, and I will be putting that on. Also got some inexpensive indexable carbide tooling to get started with. Hopefully that will be here by the weekend. Trying to keep my costs down as I get started -- not so easy I am finding out! Would love a "mentor" on this little machine and appreciate the offer of help...which I am sure I will need! How do I get your email? He moved there to take a senior copywriting manager job with Scentsy. Didn't work out and he is looking for something in the same vein. Dan |

Atlas Craftsman 3950 back gear question
#10d-260
Dan Do you have Operating Instructions for the 3950?? If yes, they show setting the clearance for the back-gear.? That and putting a little heavy open gear grease on the gears really quiets them down.? If you don't have the manual it might be available on this site or over on the "Hobby Machinist" site. They have a pretty active grp there under "Atlas-Craftsman" type machines.? And "Robert Downs" the admin here, is also over there and is a great resource.? I put a "Little machine shop" OXA size #3112 QC tool post on my 3950 and it works great. What kind of work was your friend after?? The area is going crazy for most stuff. E-mail if I can be of further help. Jack |

Jack...
Meridian, really! A really good friend of mine just moved there for a job...and then lost it. I would trade places with you in a heartbeat! I am loving it already and I haven't turned a thing yet. Got it running today and ran through all the options. Works great, though noisy with the back gear engaged, and everything seems pretty tight. Now for some tooling and some experimenting. Thanks again, Dan |

Re: Atlas Craftsman 3950 back gear question
#10d-260
Thanks so much Jack!
A friend came over and we were able to prize it off after removing the spring clip. Seems someone, in their infinite wisdom, got frustrated and forced it in and burred the key way on the coupling, essential freezing it in position. Scarred up the shaft a bit as well. We got it off, got everything honed and polished up and now it works great! I really appreciate the help!! I am in Fullerton, CA. (BTW Clausing won't ship parts to me because of that :( ) Dan |

Dan One last thing I forgot to answer.? The coupling moves strictly IN-OUT , does not turn, but must be lined up with with the "mystery spot". Jack |

Atlas Craftsman 3950 back gear question
#10d-260
dnotti Also, on the back of the 4 step pulley there is a gear that is attached to the pulley on some sort of shaft, not?labeled on the parts dia, but shown, that I can see. From your pictures I believe it is in the locked position so it just needs to be freed up, and that is the position where you would mark the coupling and?the pulley.? If I remember right I put a piece of pvc pipe and a hose clamp on the coupling so I could get a grip on it. Your right--Don't force it... Good luck Where are you located? Jack |

dnotti The u-tube is correct, starting at about 9:40.? It will not move till that "one" spot is lined up.? Will your 4 step pulley not free wheel? Yes the spindle part #34 on my part list has a key part 32 on the right hand end that i believe engages the coupling.? Also. on the backside of the 4 step pulley there is oiler.? You might get some oil in there and/or some wd40 in the front around the coupler.? It has? been over 15 years since I had mine apart, just remember the same frustration your having.?? Jack |
