Mr Pete, Weather your video’s last for ½ an hour or three hour’s, I love them. I will just make a cup of tea or two, maybe three cup’s. I find it hard waiting for your next video to come out. More Please. Peter. No that's my name Mr Pete, Peter.
I remember watching my grandpa cut gears on a very old, open frame, flat belt drive lathe. That was about 50 years ago. It ran on a line shaft along with most of the other machines in his shop. Those are great memories and I do appreciate you reviving those great old memories of working with him as a boy. He taught me so much!
Lyle - Excellent conclusion to this series, a mini course in gear making. A really good informative series. Great way to start this Sunday morning - 1st cup of coffee, beautiful sunrise and one of your videos.
Very much enjoyed this series. You talk about the depth of cut which is obviously essential yet it transfers to other shop projects as well. THAT was something I was missing desperately and didn't realize it. You help spur other thoughts for shop work directly and indirectly. Thank you!
Brilliant! My dear old Atlas 10F could use a few new gears and although I do have a new and bigger lathe, a couple of small vertical mills and a small rotary table, the idea of it making them itself just really appeals to me. Thanks Mr. Pete. You never fail to provide us home shop guys, and girls, with relevant and very useful content. Regarding your comment about the dials on the milling attachment being made for 12 year old boys; It would be great if the 12 year old boys of today had the patience and attention span to do this type of stuff. I think that few do.
It may surprise you to hear this, but I am making this attachment; not for my lathe but to use on my tiny hobby milling machine, which is just too small to fit a real dividing head on. Thanks for the great video as always!
Atlas made a similar version of this for the milling machine. It had a headstock that used the gear like this setup and it had a tailstock with a center. They also made a version for the shaper but that is quite uncommon.
Mr. Pete you are the Ultimate shop teacher ! Thanks for disproving the "spin" of the detractors who insist that our old Atlas 12 inchers are worthless. Visual and empirical proof RULES !
Hi Mr. Pete. While I know most people will not make this attachment if they have other means of producing a gear I think the series was of great value to the lathe only shop and to the beginning home hobbyist. . I found it educational, enlightening and entertaining. I for for one am very pleased you made the series. Thank you so much for doing so. Joe
“Louder than a combine” I laughed out loud at that one. Great video and very impressive outcome. Enjoyed this series a great deal. I was wondering if you have plans to go to the Midwest Tool Collectors swap meet in March at McCormicks Creek park in Spencer Indiana. If you are I’d differently would’ve be going also to get a chance to meet you. Thanks for this series it is great.
I am looking forward to making one of these for my 6" Atlas. The result is beautiful. The setup looks very easy to do and might be quicker than setting things up in a mill. MJ
I am glad that it worked so well. I enjoyed the whole series of videos from making the attachment to making the gears. So thank you for showing us and sharing your skills!
Lyle Enjoyed the series , informative and entertaining. Thank you for all the time and effort you put into this series and we'll as your other production . Cutting it on the Craftsman is a plus. I have always liked the shape of the 12 inch head and tail stock.
Absolutely love it . I know the long process to get there and it is so satisfying to see the end product!! Thanks for all you do !!! Your teachings will last until God ends time here on earth . God Bless. I will watch this 8 video journey several times even after I use you methods !!
Mr Pete I have enjoyed watching about all your videos .I have learned so much from, them. we are about the same age. I wish had you as my teacher you are so good at teaching
That was very interesting. Thanks for showing how useful a good lathe can be. Basically you are still a teacher with an even larger classroom and a lot more students. Please do the follow up on the shafts and gears.
Mr. Pete, thanks for this series. I don’t have a dividing head in my shop (yet), but this gives me some great ideas for modifying your indexing device to fit my Sheldon lathes and my Burke horizontal mill. Now all I need is to learn how to cut worm drives and I’ll be cooking on coal!
That shows the unlimited possibilities of imagination. Of course their is a limited range of gear sizes that can be cut with that attachment which could be why it was not a popular product. .Still it is a low cost way to get the gears it will cut. For someone who does not have a better type of machine it is well worth making in my humble opinion. Of course MrPete showed me better ways to make gears years ago. And that is something I will always be grateful for. Thanks for the video keep on keeping on.
Thee most explanatory video yet that I have seen that you make! My skill is nowhere near to attempt this procedure but I praise you for making the video!
I hope there's a follow up with a test run of the reverse tumbler. Maybe stick the old parts on for a before/after demo. But I'm sure this series has been finalized and in the can for a few weeks. At any rate, this whole process was edutaining. 🙂
I’ve been waiting for this series for so long. I actually purchased the milling attachment years ago for this exact procedure, making the nearly unobtainable change gears for my South Bend 405. In the interim I ended up buying them one by one, at great expense, and am now only missing a few. I’m not sure if I will ever make this project, but watching the trouble you went through to do it, successfully, was interesting and eye opening. Thank you for doing this. Entertaining and educational!
As a builder of the gear cutting attachment, I very much enjoyed the video. I never did try it and since bought a mill. I was very impressed at the quality of the finished gear. This was in my opinion one of your best actual machining videos of late. Thanks for taking the time to make the tool and actually cutting gears with it.
Thank you Mr Pete I wondered how you would control the gear pitch diameter from your earlier video when you were making the indexing attachment. I had it pictured in my mind as fitting in a square indexing tool post on the compound rest.. The mystery is solved. Always enjoy your channel.
First video I have seen where the operator actually cut a gear on a lathe.. Thank you for not running back and forth to your mill to do different functions. When you only have a lathe, it is nice to see how gears are made completely on a lathe... Thank you!
Fascinating series. If this were to be the only time you used it the setup would be a worthwhile project just to have the gear you needed. Since for most of us once we have a tool, or fixture we find other things possible that we didn't realize until the opportunity presented itself. Before I had a lathe at home I cobbled things from hardware store comoonents. Not sure if I will make one of these My milling attachment is homemade from angle iron so rigidity is iffy at best. Still if I were to attempt it I will have the ability to make gears at least as accurate as the old junkers that i am currently using. 😁 I like your setup with the part passing under the cutter for several reasons. Some you mentioned and the extra rigidity in the setup. As the milling vise is raised all the lash in the setup is increased along with the leverage of the cutting forces. In my 1946 SB the bed is so worn I have to turn anything I want straight for over an inch on the tailstock end of the lathe. As far from the chuck as possible. I also have to lock down the cross slide so it doesn't rattle while facing. Most of my work is farmer level fixes so I get along with it. Paul Pushee was my Tool Maker at UTC up until he retired in 1985. He was old school and taught me a lot. He said that on the old SB 13 that was the tool room lathe he used he had learned when to lean on the machine to get a true diameter shaft. After 30+ years I can lean on my SB and turn pretty close to straight. 😁😎
I watched the whole process from the making of the fixture to cutting the gears. I really enjoyed that series. I suppose if a fella only had the atlas lathe with the milling attachment and didn’t have a milling machine then it would definitely get you there. A little more messin around but effective. Great stuff Mr Pete.
Thanks Mr.Pete!! As always, You never cease to fully captivate!! Incidentally, I absolutely Love your Atlas Lathe, and all of the attachments!! I sure would Love to find one in that excellent shape!! So long for now!!!
IMPRESSIVE! I must admit I discounted this approach to gear cutting as I was certain the setup would be as rigid as a 10 ft. tree limb. Those cuts couldn't even be heard! As they say, "Don't knock it 'til you try it." This setup will definitely be easier on the back for a wide range of gear applications. Yet another trick you've given me for my bag! Again, excellent work, Mr. Pete, in bringing back the days of old and demonstrating just how feasible those methods really were.
When you first talked about this project i was thinking that could work okay. but it worked a lot better then i thought.. to bad they never made them in production. it would be fun hunting them down and making a gear or two.
You could cut on the underside if you rotate vice 180 degrees. Thanks for all your lessons I've been a machinist for 57 years and can't remember ever cutting a gear.
Thank you so much for making this series of videos and displaying your machinist / teaching talents. Back in the late 1990's I made a home made gear cutting jig to use in my milling attachment on my little 6 inch Craftsman lathe (using the picture in the lathe manual - not much on the internet back then for drawings or plans) so I would have the ability to make change gears and other gears for it. The change gears used on the 6 inch lathe are 24 DP with a 14.5° pressure angle. With the limited travel ability of the milling attachment for the 6 inch lathe to use the gear cutting jig I made it is necessary to rotate the vise 180° so the two screws extend out the bottom and the jig is mounted at the top of the vise and even by doing this it is necessary to cut the blank with the cutter entering the blank at the bottom. While visibility is a little limited you can hear the sound of the cutter to get an idea of how the blank is cutting and also view the cutter if desired using an inspection mirror. With the setup I have I have cut gears with 16 teeth up to 64 teeth which covers the range I need to cut all the change gears. Originally back in the late 1990's I purchased plans to create a quick change gear box for the 6 inch lathe and made the 4 compound gears (16/32 teeth) as well as turned the blanks for the speed changing gears but then lost interest in the project. Looking at the set up on your 12 inch lathe the smaller gears can be cut as you show but to do a larger tooth gear (64 tooth as an example) you might also have to rotate the vise 180° and cut the blank from the bottom - not sure. Since you have a milling machine this would be the easier way to go but thought I would mention it in case someone watched the video and like me only had a lathe and the milling attachment. Since I am now retired I have again taken up interest in the lathe and I hope to create four gear sets similar in design to the six "Gearsettes" that Clausing Service Center offered for sale for the 6 inch Craftsman (and Atlas 618) lathes years ago to make threading and carriage feed set ups easier and faster - not sure if you are familiar with them. Basically they offer consistency as once the desired thread or carriage feed is selected the operator just has to select the correct gear set and the appropriate lead screw gear to create the correct gear train. The gear set engages with the 16/32 tooth drive gear on the lathe (which is determined by each gear set) and the change gear that goes on the lead screw is always mounted at the front with the space behind it. The original gear sets came with a metal disc that was stamped to indicate what thread or carriage feed each covered and the lead screw gear required for a certain thread or carriage feed. The gear sets I hope to make will probably not have the stamped metal disc but I can print out a chart and laminate it to keep on hand by the lathe. The gear sets also result in only having to set the spacing correctly between the gear set drive gear and the lead screw gear and then the gear set driven gear and the 16/32 tooth drive gear on the lathe so the gear teeth mesh properly. Not sure if similar gear sets were ever offered for the 10 and 12 inch lathes or not but if someone had a 10 or 12 inch lathe without a quick change gear box and were cutting a bunch of different threads making a couple of gear sets for the larger lathe might be an option for easier set up of the gear trains.

An absolute pinnacle performance!!!
Job well done.👈
The Tennessee Mole Man 👍👍👍
I got eight moles last summer
@@mrpete222 I've lost count... it's been a bumper crop here lately!!!
Good morning Mr. Pete! That gear cutting went perfectly. your setup is very Rigid
Thank You Mr. Pete. I enjoy watch your videos and I chuckle at your sense of humor. Thank You Again. Your the best shop teacher.
Very much enjoyed this series.

Nice gear. You must be happy it worked so well.🔧⚙🔩
I appreciate your time Mr. Pete.
Thanks
Mr. Pete, I said it before but I will say it again, “You keep doing You”. You are a breath of fresh air for me and so many others.
👍👍👍👍👍😄😄🙏🙏😄

Great series - I should say 'so far' as I am looking forward to seeing you finish the shafts and other gear.
Very interesting and informative as usual mr Pete 👍
Direct indexing for the win! This series gives me a new appreciation for what I can do with my lathe. Thanks, Mr Pete!
Glad to help
Another reason why seat taking it all in, hopefully some of talent will be transferred to me, Thanks 🎉
👍👍
This made me want to make stuff to cut gears even though I don't need to. Thanks for the info. It was very interesting.
Thanks to Mr Pete, I just learned how to do something I will never do! But how better to spend an early Sunday morning. Cheers! Well done.
Wow, that did a good job, so much prep time making the fixture and cutting the gears. Thank You for the video..
Yes, I put weeks into this project, lol
Thanks Mr Pete I love this technical content. You will always remind me of my shop teacher Mr Nordoft
😀😀😀
“Louder than a combine” I laughed out loud at that one. Great video and very impressive outcome. Enjoyed this series a great deal.

I have no plans at this time, but I heard Keith mention it
Thanks for sharing 👍
This video is awesome. Everything turned out well. Thanks for doing what you do. Wish I had you for my shop teacher.
Thanks so much!
I am looking forward to making one of these for my 6" Atlas. The result is beautiful. The setup looks very easy to do and might be quicker than setting things up in a mill.

👍👍
That worked beautifully. As one of our old boys used to say, "it looks like it grew like that!"
Thank you Mr Pete. That was a good watch.
I am glad that it worked so well.
I enjoyed the whole series of videos from making the attachment to making the gears. So thank you for showing us and sharing your skills!
Thanks again!
Excellent conclusion to your gear cutting jig/fixture project! 👍🏻😊

Beautiful gear -thanks for sharing your skills with us.
Thank you kindly!
Absolutely love it . I know the long process to get there and it is so satisfying to see the end product!! Thanks for all you do !!! Your teachings will last until God ends time here on earth . God Bless. I will watch this 8 video journey several times even after I use you methods !!
Thanks so much!
That all worked out perfect. A great option. Very nice support of the oil cup. 👍👍👍👍👍
Mr Pete I have enjoyed watching about all your videos .I have learned so much from, them. we are about the same age. I wish had you as my teacher you are so good at teaching
Wow, thanks
Well done Lyle. We all love to see the tools you fabricated in action after they're done.
Thanks
This was a great mini series
Neat! I need to try this on my Atlas horizontal mill.
Great video pete, keep'um coming.
That was very interesting. Thanks for showing how useful a good lathe can be. Basically you are still a teacher with an even larger classroom and a lot more students. Please do the follow up on the shafts and gears.
Yes, I would say that came out perfect!! Nice job Mr.Pete. Looking forward to the next project!
I will add this to another one of my favorite how-to videos. This rookie machinest is learning a lot from you.
Thank you!
Great to hear!
Mr. Pete, thanks for this series. I don’t have a dividing head in my shop (yet), but this gives me some great ideas for modifying your indexing device to fit my Sheldon lathes and my Burke horizontal mill. Now all I need is to learn how to cut worm drives and I’ll be cooking on coal!

Well done Mr Pete. Thanks for showing us how it is done.
This series turned out great! Thank you for teaching us this!
👍
Great job! A good looking gear and done on a lathe. That old gear didn't look nearly as bad to me until you compared it with the new one.
Thanks 👍
That turned out awesome. Would love to see a follow up of the completed gear set.
I’ve been waiting for this more than the Super Bowl tonight. Excellent series as always
👍👍
That gear turned out a lot better than I was expecting and really re-enforced for me how versatile a Lathe can be if you have the right tooling.
That shows the unlimited possibilities of imagination. Of course their is a limited range of gear sizes that can be cut with that attachment which could be why it was not a popular product. .Still it is a low cost way to get the gears it will cut. For someone who does not have a better type of machine it is well worth making in my humble opinion. Of course MrPete showed me better ways to make gears years ago.

Great video. Excellent explanation of work. Great setup. Thank you for sharing.
Thee most explanatory video yet that I have seen that you make!
My skill is nowhere near to attempt this procedure but I praise you for making the video!
thank you very much
Thanks for another great video.
I hope there's a follow up with a test run of the reverse tumbler. Maybe stick the old parts on for a before/after demo. But I'm sure this series has been finalized and in the can for a few weeks. At any rate, this whole process was edutaining. 🙂

I always enjoy Mr. Pete's videos. They always lift my spirits, and are filled with small tips. The screw driver hole was genius.
Thanks
Thank you Mr Pete I wondered how you would control the gear pitch diameter from your earlier video when you were making the indexing attachment. I had it pictured in my mind as fitting in a square indexing tool post on the compound rest.. The mystery is solved. Always enjoy your channel.
Great series! Very educational and interesting! Thanks for doing these!
Appreciate the time you invest in these projects, the end product looks "factory fresh" .

Thanks for this, these hands on videos really give me confidence to have a go myself.
Great video series. Even a non-machinist like me finds it very interesting and informative. Thanks for all of your efforts.
Wow that worked out perfectly 😁👍👍 great conclusion to the project well done Mrpete 👍👍♥️
Excellent little attachment thanks for the video
Great series,thanks for all you do for the community🤗😎🤗😎
Thanks for watching!
Great video.
What fun project this has been.
Well done and thank you.
That worked like a charm! I really enjoyed de series Mr. Pete! Thanks for sharing your knowledge!
Those gears came out nicely!!!
Fascinating series.
If this were to be the only time you used it the setup would be a worthwhile project just to have the gear you needed. Since for most of us once we have a tool, or fixture we find other things possible that we didn't realize until the opportunity presented itself.
Before I had a lathe at home I cobbled things from hardware store comoonents.
Not sure if I will make one of these My milling attachment is homemade from angle iron so rigidity is iffy at best. Still if I were to attempt it I will have the ability to make gears at least as accurate as the old junkers that i am currently using. 😁

In my 1946 SB the bed is so worn I have to turn anything I want straight for over an inch on the tailstock end of the lathe. As far from the chuck as possible.
I also have to lock down the cross slide so it doesn't rattle while facing.
Most of my work is farmer level fixes so I get along with it.
Paul Pushee was my Tool Maker at UTC up until he retired in 1985. He was old school and taught me a lot.

Hi Mr Pete good video make pt 3 That contraption works sweet . Good job . JM
Best video I've seen on making gears, Thank You.
Wow, thanks!
Great work.. love watching your machining videos! Thank you Mr. Pete for sharing with us!
👍👍
Great going Mr. Pete. You never cease to amaze!
😀
Thanks Mr.Pete!! As always, You never cease to fully captivate!! Incidentally, I absolutely Love your Atlas Lathe, and all of the attachments!! I sure would Love to find one in that excellent shape!! So long for now!!!
Watch craigslist for an atlas
