Great site that I just found today. Got a '37 Craftsman 12" that does everything I need. I added a power window motor years a go. Your neighbor in Citrus County.
These are good and usable machines, and this is a great channel! Adapting another brand steady rest is important because often they are missing, too expensive for an original most of the time, I just did the same for an old lathe.
I have 6 atlas lathes I've restored too sell later as people finally realize vintage machines are best way to buy,, and just bought a 11 inch Logan been hopeing to get my hands on one
@@donsengine3158 sweet machine,, but bring help about 700 lbs,, mine has zero run-out and no way wear and not a nick and no end play in any funtion , but front of quick change gear box busted,,, not complaining for 300 bucks I'll sell one of my atlas's and buy a gear box,,
@@donsengine3158 no problem once I got it home with my Kubota tractor and seller had a 2 post lift set it right on my truck,,, you will love it,, took mine all apart it's like new condition inside,,, seller had 60 people message about it but moved me to front after seeing my lathes I've restored was his grandfather's and wanted it done right,,I'll never sell this one,, Im in love,,lol
Nice machine! I have two of them. Wouldn't give them a second glance when I worked as a machinist but you can do a lot with them if you have some patience.
Great video. I just finished restoring the same rusty Craftsman Commercial. You're so right that when the lead screw is engaged at higher RPM it sounds like a hundred dying cats. I'll be doing more research on motor replacement now..
Hey Mason. Love that hundred dead cats analogy. Any piece of equipment that sounds like its getting mangled when you fire it up drives me nuts. You may notice most of my stuff is set up for soft starts. The Craftsman lathe really came into its own with the DC motor. I contemplated using an AC motor with VFD, but I was a bit worried about the need for using a higher hp motor ie.. 2 hp so as to maintain sufficient power at lower rpms. The lathe wasn't really built for that and I didnt want to get it in over its head. The DC motor gives very nice cutting with plenty of power at all RPMs without having to worry about it coming onto a high hp. I could get away with it on the monarch as its built much heavier and can take more HP than you can throw at it. All in all, I'm really pleased with the craftsman and do a lot more with it than what I'm willing to show on video so as not to get lambasted. Thanks for watching Don
So is keeping the lathe level just a way to make sure the bed is not twisted, ie I would think a non twisted bed should cut properly even upside down or sideways.( other than the chips would fall differently)....as from the material perspective it doesnt know what way is down. Or am I missing something really basic that it being level fixes that a non twisted and non level bed would have a problem with (very possible I am missing something basic).
2:57 "There may have been a production shop out there that had one of these in the back." I've heard the Atlas lathe called "the lathe that won the war". So there's that.
When the Craftsman Atlas was sold it "was" an entry level lathe. However I would argue next to the plastic crap lathes of today an old Atlas would be more of a mid-level tool. You would need to spend $4,000.00 or more on a modern lathe to get the quality and dependability of an Atlas. Just my opinion and if I'm wrong, It won't be the first time.
No, you're probably pretty much on target there. You'll notice hat everything I own, that wasn't inherited or given t me, Is old U.S. Iron. You can guess which side of that argument I'm on. Don👍
Sure thing. Thanks for watching. If there's anything in particular you'd like to see, throw some ideas at me. Sometimes I get off on my own thought process and forget that sometimes I may have missed something. Happy New Year. Don
Thank you for all the information. I just bought this same lathe and when I went to pick it up there were only plastic chips. So, I don't think the original owner ever did any metal. Just the white plastic while learning.
That was lucky in itself.. good luck with it. Its funny, once you get one of these Atlas lathes, you never seem to want to let it go. I've had other what would be considered "Superior" lathes to this, but they're gone and its still here. Part of that may because of my history with it, but they really do underpromise and overperform. Something to think about. Good luck.. Don
@@DustinRogersinMO The slide lengths are 38" on the carriage and 11" on the cross slide. I think I had to cut the cross slide down to that size though. These magnetic scales can be cut to length. Don
Don , I've been watching your vids on this Atlas-C mods. Very fascinating! I just bought one of these lathes, though it's older than yours I think. I've got it running, but would like to look into all three of your addons for my machine. Could you list the actual names/brands/models of these items? As I too want to reduce the loud clanking. BTW, I saw your compound post mount mod too! That is sweet! Thanks Paddiman772
The wiper motors sure do have torque, For example on my drill press the table z-axis crank handle broke one day so instead of making a new one I put the wiper motor on there instead and it easily raised that table with a heavy drill press vice on it. To simplify things I just put a small garden tractor battery on the floor. (my good friend owns a very large auto salvage yard, so parts are free)
Great video, I have the same lathe. I think I will copy your DRO design, if that is ok. One down side you can't put a taper attachment on with the DRO in the way. Have to use the offset tailstock method to cut a taper instead.
Hope it works for you. I like that its not intrusive to any of the X-Y axis movements on the bed. Most tapers I need to do are pretty short so I take care of them on the compound. I don't own a taper attachment for his machine, but I have thought about setting one up without messing with the DRO scales. If I could find an inexpensive one for my Monarch (hear the laughter) Ide just assume put one on there as its a lot more rigid. Just one of those Get To projects. Thanks for watchin. Don
Your changers could be used to update many different types of lathe's to improve their performances. Atlas lathes are great, and after 40 years leave Chinese lathes for dead. Many a model engineer have used Atlas lathes in the construction of Gold Medal winning locomotives, steam driven beam engines and model engine building. In todays world it's all cnc were the skill is only in writing code, these old lathes in the hands of good machinist produce tolerances that any CNC can deliver.
Nice video Don, i have an Atlas 12 commercial lathe and i love the thing. Is it posable to send me a part number or tell me witch asian lathe i ought to look up in order to try and find a steady rest like yours?
Hi Tony. I wish I could help you on that. I just found my steady rest by accident. It was listed as a 12 inch swing steady rest. No indication for what lathe. I just decided to take a chance and went ahead and got it, then did the modification.
Hey Nice video . If someone is looking to install a new or use motor that is adjustable they could go with a 3 phase 1 hp motor and use a VFD and i think you could buy a VFD that can convert 120 v to 220 v 3ph but if not for sure 220v single to three phase . i did this on my delta band saw . well that's my 2 cents. JM
Yes, I did it on my delta band saw, my mill and my Monarch lathe. The DC motor is really nice on the Craftsman lathe as it has very smooth, has a very linear response and with lots of torque from bottom to max. If I was going for the AC/VFD Ide of probably used a 1.5 or 2 hp motor to try and achieve similar results. I don't show it on my videos so as not t catch flak, but the DC motor can really make the lathe eat some steel. 2C always welcome 👍 Don
Don, great video. I just found your videos, and subscribed. I plan on modifying my lathe just like your Electro Drive. I found wiper motors on eBay, but can you share a shortcut to the transformer and control unit? Thanks, Bob in Sarasota
Hey Bob, Sure. The items I purchased are long out of my archives, but these would be equivalent to them. Don Ebay - 12V 5A to 60A Adapter Transformer Power Supply AC-DC Ebay - DC 10-55V MAX 60A PWM Motor Speed Controller CW CCW Reversible 12V 24V 36V
Awesome Electro Drive!!! Do you remember what application that windshield motor was for? I would like to add that to mine but all I've been able to locate ( guys at Napa asking if my lathe is 4 or 2 wheel drive) is a motor for a UTV. They look a little small, not sure if they have the same rating only in a smaller package? Great video, lots of info and inspiration!!!
Actually its an atypical automotive 2 speed wiper motor. They're all pretty universal. You should just hit up breaker for on. A lot cheaper and you can fish around for what you like. The one used was off a Winnebago RV. Bu they ar epretty generic.
Hey Keith. I actually don't remember right off. I think the X was around 28 inches. It has to allow total carriage travel The Y was 13 or 14 and I had to chop it off to 11 if I recall. It was while back now. They still work great. Don
are you able to switch back to gear drive if you want to cut a thread? I may be doing some threading on my atlas/craftsman lathe and I want to make sure I don't loose that ability if I switch to a powered crossfeed.
Absolutely. I haven't seen this video in a while, but I do believe I showed my quick lock/unlock to engage the electric drive. When its out, I can run the lathe like the factory designed it.
one old gentleman told me that craftsman lathes had their spindle shafts built in England and ground so well that they virtually had no rainouts at all! I dont know which yrs had that done, maybe all? If so you will be better off with one. Many stuff branded by craftsman was outsourced to major and well established manufacturers that made high quality units/parts. so the fact is that many 30-50yr old craftsman equipment are high guilty underdogs.
Hi Ronit. Yes, Craftsmans were Atlas which according to my manual is a Clausing subsidiary. They certainly hit above their weight and you can get some nice work done on them for sure. I'm sure there must have been some cross pollenisation in those plants that allowed such a bargain basement price for its time, to come off with the level of performance that you get. Thanks for watching. Don
Getting the same lathe, could you give me the specs of your electric DC motor? Don’t have a friend who would give me a conveyor belt motor but perhaps I could look for something suitable? Thanks!
