Thank you so much for these videos. As a kid I watched my dad set up his Atlas and even though I became a design engineer (electrical) I never dabbled in the fine art of metal work. Now, I am crashing your videos trying to get dangerous enough to make some basic parts on that Atlas machine which I have now appropriated - ha. This vid goes a long way to not getting psyched out by the lathe.
Thanks for the tips, Lyle! Feel free to repeat yourself, it drills that stuff into my head a little better that way 😁. Wasn't sure if it was possible to do metric threads with the change gears I have, now I know it is. However, I'll have to find the conversion for a much earlier model 10" Atlas (model 10-D) but at least my search won't be in vain. Thanks again, Mr.Pete! 👍😁👍
I have the almost exact Hanson metric Tap and die set! I also have a 10 inch Atlas lathe too, now I just have to get as knowledgeable on its use. . . . Reading, learning, and practice make perfect, or so I am told.
Super useful. U.K. Still find unc & unf, Whitworth, British Standard Fine, British Association (most electronics) & lots of industry specific e.g. British Standard Gas, British Standard brass & others. Still find fractions better than powers of 10, less chance of being wrong by x10!
Mr. Pete, since you have extra sets of change gears (and a Bridgeport that you can make gears on...), how about making a couple of replacement/duplicate banjos that can have the “Most Popular” gear trains, pre-loaded and ready to swap out?
As you said metric is very easy to understand and its more easy to understand what you are trying to tell. I was looking for a video that show how set up the gears and levers and here is the right video.thank you for the videos. Its really help me
Was just thinking: a good piece of paper to use for spacing the gears would be a bit of currency, such as a foreign bill you can't use, left over from a trip. Currency tends to be pretty tough, so it'd last a good while, but it's also made to not be too stiff.
Hey Mr. Pete, 12:12, you put 56 on front at position D as directed, but when I watch her running at 15:38, it looks like the 56 gear doesn't engage with any gears. Apparently in this configuration it's just there to hold the 52 in place?
Thanks for the video. Concerning cleanliness, have you tried wearing vinyl gloves? They have good tactile properties, they keep dirt and grease and grime away from your hands making personal cleanup much easier.
I'm not sure why some Atlas lathes are so noisy...I have a 10d model that was made in 1936 and it barely makes a sound when running. The only real difference I see is the feed reverse lever on mine is at the headstock end of the lead screw instead of inside with the change gears, but mine also uses plain bearings instead of timken rollers...maybe that is the difference in the noise level. Great video as usual. Thanks Mr. Pete.
+dale pratt I just gave up a babbit-style 10-inch lathe to make room for a timken-style 12-inch which I'm assembling. The old lathe wasn't noisy at all but I expect my new one will be. Time will tell.
+Rick Rose Good luck on the lathe build, Rick. I've also heard (or maybe I read somewhere) that the plain bearing lathes give a slightly better surface finish than roller bearing heads. I do love the old lathe.
I have a boley & Leinman lathe, but no manual or thread cutting chart... Is there a way of calculating what gears to use for the pitch I will cut ? Thanks
MRPETE. i'm looking for a book or manual for a Craftsman 109-21270 mini lathe,would you know and please help to where i could purchase one that would have all the questions that i desperately need answered. Thank you Luigi DeLucia
Might you be referring to my Atlas video lathe course? That is listed for sale on my monthly promotions. Most recently, April special shop video courses tubalcain. Search for that CZcams video
Very nice and clear video. Your tap chart is interesting. In any system, the tap equatiion is TD = OD -P where TD is tap diameter, OD is nominal dimension of screw, and P is the pitch. In metric this is easy. M6x1.0, drill 5mm. I do it in my head. It works in Imperial, of course. So 1/4-20, pitch is .050, OD is .250, drill. .200". But now you have to convert that to either Morse number or fractional. It is the use of fractions that makes Imperial so cumbersome. Well, no, there are feet too. I grew up in Metric and find Imperial absurd. I have no intention of ever buying an Imperial machine. It is interesting that Atlas got around the use of a 127 tooth gear. That is the standard metric-to imperial transposition gear. It's all in the ratios, so I think they were pretty clever.
Switching off the machine isn't really good enough to ensure safety when working on the machine. The power supply should be disconnected as well. It's easy enough to bump the "on" switch when you're working on it.
Hello, great videos sir, I'm talking about Brazil. I have a lathe that I inherited from my grandfather, an atlas th42 lathe, would you have a PDF manual of that lathe? Or would you know how many gears it has? I will be forever grateful.
+Thomas Coughran - Actually the vast majority of the scientific side of the space race was in metric. But, at that time, many more countries were imperial (only 3 are left today!) so NASA converted their announcements into something the masses would readily understand.
I was amused that your hardware store had three or four pitches for M12 nuts. Here in Europe you have pretty much no chance to find anything other than the preferred pitch for any diameter in a hardware store. If you need a different (fine) thread you have to go to a specialist (industrial) supplier or make it yourself!
I too grew up on the Imperial system and am more comfortable with it but, as you say, the metric system is superior and easier to understand. I give several examples to people to help convert them (not that it works). Our money is metric (base 10)! Wouldn't it be horrible to make change if the dollar was divided into 64ths? Quick, which is bigger, 3/8" or 25/64"? How about the larger of 9.5mm and 9.9mm? Easy! Lastly, try dividing in half 7-1/2" versus the half of 205mm?
+Rick Rose - You are correct, hadn't thought of that. 1000's of an inch is the standard. Of course there are still non-metric 12 inches in a foot, etc, etc. I am not quite sure that the word "metric" literally means any base 10 system or just the one system created in 1799 during the French revolution.
+Rick Rose that is not metric as it is not based on using the meter as the base unit of measurement. measurement in .001's of an inch is still imperial.
Hi, Mr Pete. I believe that you made a statement in the beginning part of the video that you can NOT cut metric threads on an Atlas-Craftsman lathe equipped with a quick change gearbox. That is NOT true. Atlas published a “Quick Change Attachment Handbook” for 10” lathes (works for 12” lathes also). The book is 72 pages and has charts for change gear setups to obtain odd threads and feeds from 1.25 threads per inch (.8000” feed) to 1000 threads per inch = .001” feed. So you set up the change gears per the table and then put the two change box levers in the positions as shown in the table. There is also a one page table showing the gear setups and lever positions for metric threads from 0.25mm to 7mm pitch. I have a electronic pdf file of this handbook copyright 1947. If you need it or would like a copy let me know and I will email it to you. Thanks for making these great videos.
Folks like you, who take the time to make these videos to help clueless folks like me, are living saints in my book. Much obliged, Sir.
What a blessing you are sir. If only I could have had you as a shop teacher, but as you might have guessed we had good ones too.
+mrbakerskatz We do have Mr Pete as a shop teacher; right here, right now. :)

+Springwood Cottage Thats a lot of threads. I worked with the tiny BA threads when I was 16 building a stuart engine
Can you do this with the quick change box installed on the lathe or does it have to be in this configuration?
Mr. Pete, since you have extra sets of change gears (and a Bridgeport that you can make gears on...), how about making a couple of replacement/duplicate banjos that can have the “Most Popular” gear trains, pre-loaded and ready to swap out?
That is a job for a young man

Hello, could you tell me how many gears did the atlas th42 originally have?

question nite on atlas were do find this

Do you know of a video like this for Gear set up on a south bend 9c 10jr?
Sorry, do not
Thank you Tubalcain,,, interesting as per usual... Take care.... :o) O,,,
I have a boley & Leinman lathe, but no manual or thread cutting chart... Is there a way of calculating what gears to use for the pitch I will cut ? Thanks
I would say it’s baguess & bgosh till you find the right combination
Ok Pete, thanks ! I was concerned that might be the only way forward ! I guess test each gear on a bit of scrap and see what pitch it gives yes ??
thanks Pete

I do not know how many gears. Go to vintage machinery.org. See if they have the manual you require. I do not have one
Thank you very much, I'm a fan of your CZcams channel.
I downloaded a PDF of the Atlas "Lathe Operations Manual" from Vintage Machinery dot org some time ago.
The Imperial system got us to the moon and back!

+cemx86 MOstly agree with you. But, the divide by half argument falls down if you pick different numbers. Like 10" vs. 197 mm.
+cemx86 Of course machinists have always used a metric system. The basis was the inch, but it was divided into factors of 10.
