AMAZING ATLAS GEAR CUTTING FIXTURE Lathe pt 1 835 housing tubalcain 

These are the videos we novices love the most, a great learning experience, also have been watching your training videos on how to run a Bridgeport mill and South Bend lathe. Love them, and thanks for taking the time to make them.

Very nice Mr Pete. I have drilled deep holes in a lathe project. Removing the chips required moving the tail stock. I placed a spring clothespin on the bit to aid me when pushing the drill back into the work. This saved me from jamming the drill into the bottom of the unfinished hole.

Thank you for taking the time to patiently go through and explain all the documentation at the beginning. It really helped me understand the work you were about to undertake.

May never make one but always pickup ideas….. Thanks for all you share🎉

I enjoyed this video and I am looking forward to the rest of this series. It’s amazing how many options were available for such a relatively inexpensive machine. Can’t wait to see how the dividing end all works out.

That looks like a fun project. I'm going to have to print out a set of those plans. Thank you very much Sir.

Going to be another great series to watch. Thank you as always for the content!

I'm the guy that made one a couple years ago. I believe I sent you a few pictures and both sets of plans back then. It was a fun project. Since then I purchased a mill! Looking forward to watching your build. I'm sure you will add some nice touches.

Nice project. Your archived catalogs hold a wealth of knowledge.

Lyle - Good video and very interesting. Will be watching all the segments to see how it all goes together. Thank you for continuing to gives us this edutainment, it is much appreciated.

Very educational Mr.Pete as usual.Love your self efacing sense of humor.You are a humble man of great talent . Thank's always fun to watch you in action

Another awesome project from RU-vid's favorite edutainer. Can't wait to see it cutting gears.

Thanks Mr Pete for another great video. Can’t wait to see the project when it is finished.

Thanks for another great series. Although I’ll never make this project it’s always interesting to see how it’s done. I have several inventions and unique modifications in my shop that could be shared with viewers through your channel if they’re interested. One is a ball bearing bench mounted fixture to very accurately balance grinding wheels. It uses an external balancing ring with small weights to perfectly balance surface and bench grinding wheels for vibration free operation.

Is it me or are all the good projects from the old catalogs....

Great video. You are a fun teacher with a healthy sense of humor.

Mr Pete, great video. I have a 1939 Atlas Craftsman 12”x24” lathe. It’s currently broken down into its major subassemblies awaiting me to start a complete refurb. I bought your video series a while back. Thanks for that wonderful resource. I very much appreciate all of your videos and the time you put into sharing with us. Being in my late 60’s, I’m right there with you during your rants. Must be a generational thing or just plain correct thinking. I very much enjoy them too. Hope you had a great Christmas and New Year. Looking forward to the rest of this series and some day soon making this gear cutting fixture. Best Regards, John from Chesapeake,VA

This is going to be a great series thanks Mr Pete

Lookin forward to the complete series... Don

And again another great video Mr.pete thanks for sharing. I'm gone to try to make this project I hope I get a A+ plus on it have a great day.

Thanks for the interesting video Mr. Pete. I always get a little smarter as I watch your productions.

What a project, the way a creative man can make if he had not have the right machine

Thank you for coming out with this series. I intend to make one of these for my Atlas 12” lathe.

Thank You Lyle.... Where else could I ever find this information ??? You ALONE cover all this soon to be lost in time information!!! Your efforts are appreciated by the few folks left that care for hands on machining... TM

This is a great project and I predict that several will be made. Thanks for the video keep on keeping on.

This video is instructive and fun. Can't wait for the next installment. Thanks Mr. Pete

I've been using my Diamond Tool Holder for 15+ years and I love it. It makes great cuts, but the reason I like it so much is that I'm cheap. I'm still using the same little nub of HHS I started with. Sharpening is a couple passes on a bench sander.

Thanks for the video. You have some of the best machining video on the web. Thanks again Mr. Pete

Great video.Waiting for part 2.Thank you.

Been waiting for a good long project - pay prayers have been ansered . It's great to see you back in the saddle again !! Thank you

I own a '48 12" QC Atlas that I have cobbled together from various pieces, and I'm always excited to watch every Atlas and Atlas-adjacent tutorial you release. As someone with only space and money for the lathe, for now, I appreciate everything that helps facilitate basic milling machine work on the lathe. I eventually got my hands on an appropriate milling attachment for my lathe, but I'm always considering ways to mount milling work directly to the cross slide or compound, for rigidity. Thank you, by the way - I really appreciate the work you do, consistently adding entries to your considerable library of The Lost Art Of Metal Shop. Sometimes, your work is some of the best and/or the only information on certain topics available anywhere on the internet... So again, thanks for sharing what you know. There may not be a huge number of viewers, but we definitely value the archive of Mr Pete shop knowledge. Cheers!

I really enjoy this kind of content and know it must be a challenge to keep coming up with projects of this type. Keep up the good work.

This is a great topic and I have no doubt that like myself, others will throughly enjoy it!

Using this attachment you can 3d print a plastic gear and use that to index a metal gear blank.

Oooo... Intriguing new project, yay! The prints are quite readable on a 42" tv 😁 TTBOMU, the copyright applies to the drawing, not the part. Recipes aren't copyrightable (although the surrounding text is), and i believe (IANAL) that the same principle applies here. The hole came out tight because it was on size. Without 0.0005"-0.0010” of clearance, it won't turn freely. This is why most of my reamers are over/under reamers.

Great video lyle!

Great project!

Thanks mr Pete, love the video. Made very big mistake. Sold all my equipment, lathe mill,drills etc because I moved and I'm 71 years old. Thought I was to old. Now I am starting over. I'll let the kids worry about selling everything at my demise.

Terrific as usual.

All ears and Eyes here Mr. Pete.

Great video Mr Pete! I am looking forward to the rest of videos for this project!

To Infinity and beyond! (Monitor screen at beginning) lol. Also I love seeing genuine technical drawings hand drawn - t-square and set squares compasses and protractor and a fussy eye for detail! Thank you for sharing and happy new year, Mr. Pete!

I’m excited to see another multi-step multi-video project, thanks again! I hope you got my email regarding the wrenches.

I eagerly await the next. Too many questions so I'll watch. : - )

That wartime catalogue is an absolutely amazing find Mr. Pete!!! Just looking at the presentation and style of the pictures is deeply atmospheric! It takes us directly back to those dark times. I wonder how many items for the war effort were ordered from it?

This type of stuff is very interesting thankyou.

Very excited about this project

Can't wait for the rest.

There are tons of cheap, Chinese milling attachments available for on eBay. It would be a great project! I would modify it so it doesn't require an identical gear, which may be either unavailable or too damaged to be useable. Instead, it would use a round disc with holes for the teeth positions drilled around its perimeter. A pin of the same diameter plunges into each hole or indexing.

Thank you Mr Pete for another great video! I never get tired of your projects. I love them Will make this one can use it on my mill also

I dig it!

I built one! Needed a new 20 tooth gear for my Atlas 12", Downloaded the Atlas plans for free somewhere on the internet. Poured some aluminum blanks, turned them to the right dimension and got some gear cutters off Amazon. Made my own arbor for the cutters too. Fun project especially making the plunger. Can't wait to see the rest of this series!

Nice !

Happy New Year Mr Pete noted the special cameo appearance of the machinist mallet you caste some years back eagerly awaiting part two

Great project, I like this, thank you :)

I have not seen a lead hammer since I was a Westinghouse apprentice 50 years ago. I plan to build this tool and use it in my Enco mill. I need to make a lot of gears to rebuild a 14 1/2 inch South Bend 2 handle gear box that destroyed a bearing, which then tore up most of the gears. In stead of buying those expensive gear cutters I use a fly cutter that I made that holds a 3/8 hss bit at 90* hand profiled for the teeth. ( I still hand sharpen my drill bits too, lol ).

Thanks again

Amazing. That ten page drawing set had a two view orthographic projection plus an isometric view for each part, but the last page of the whole assembly looked to be a trimetric projection. Speaking as a former technical illustrator myself, that is awesome. Of course, nowadays you just rotate the damn thing with your mouse in Fusion 360. Not nearly as elegant as hand drawing it in pencil and then inking it on Mylar, in my opinion. Thanks Mr. Pete.

Hello Lyle, I made a similar item to this, out of my head, about 9 years ago. I use change gears from a Rexman lathe I have, to work out the teeth numbers i require.

Awesome

Thank you for showcasing this project. I have this gear cutting attachment, made exact to the Atlas blueprint. It's a great accessory to the milling attachment. Looking forward to seeing your version, as I know it will be excellent. Happy New Year !

You could have used round bar. With a flat on for orientation although it would not matter if it was fully round as the vertical slide vice would easily grip it. Would be easier to make for those without a milling machine. Thanks from Australia.

I don't have a dividing head for my mill so I may make a version of this for my mill. I can 3d print "master" gears to be cut in steel.

nice!!!

I’m happily confused Mr. Pete

Cool

Another great video Mr. Pete. I'll be following this series with great interest. I believe that indexing attachment, with some modification, would work on the Atlas MF or MFC horizontal milling machine.

At about 9:04 of the video you show the pictures of the different versions of the shaft showing different sizes of thread at the ends of the shaft. I believe that the smaller diameters (such as 5/16" thread) would be for making smaller diameter gears such as might be found on a 6" Atlas lathe for change gears. If a 16 tooth gear with a DP of 24 was being made this would require a gear blank with an O.D. of .750" if I did the math correctly. The cutter would be cutting to a depth of .090" to create the teeth profile so the diameter of the gear at the valley of the teeth would be .570" (.750" - .180") after it was cut - a 3/8" hex nut would be too large to use to hold the gear blank on without the risk of the six 9/16" hex flats engaging with the cutter teeth to some extent. A 5/16" hex nut that is 1/2" across the flats might sneak past the cutter without the cutter touching it. This is possibly why the shaft is shown with different diameters of thread - just my opinion.

Thanks for a very informative video,maybe I can adapt this to fit on my 20" Boye' & Emmes, thanks for all you do for the cause🤗🤗😎

Great project! I'd make one for myself, but I already have three mills. Still, it might be useful as a generic indexer.

Happy

16:25 oh no Mr Bill ................. I mean Mr Pete

Old and incompetent and full of Swedish humor great work Mr Pete.

Unless someone gives me a mill and the space to put it... I will definitely be making this, though maybe for use with a specialized fly cutter & single point HSS cutters... after I make the milling attachment, and after I make readable dials, after I fix my tailstock... but it is on the list!

Chucking reamer may have been resharpened which would slightly undersize it. I see you are using the spill proof paint cups for your cutting oil, I use them also but I place a decent size magnet in with the oil and it holds the oil container down where I want it to stay and I don't worry about it vibrating off and falling.

My posts keep disappearing. Websit eis up, please reach out to me for plans if you need them before I get them posted later.

16:26 You are so funny 🙂

Informative and entertaining as ever. FYI : at 22:17 the first drill kicks upwards as if it hits below the centre of the starter hole, then at 23:23 the larger drill does the same, but to a lesser degree. Any upward kick of the reamer as it engages at 24:12 is minimal, but after re-watching all 3 at half-speed playback I think it might just have done so. Perhaps a tiny chip in the tailstock quill or sleeve ?

I think if a few dimensions are changed copyright is hard to enforce

I began making one of those years ago then bought the gear and haven't completed the fixture! I don't know where I got the inspiration but I don't have a blue print or plans for it.

Is it possible you ran the first reamer on aluminum still hot from boring? Maybe it shrank when it cooled, enough that you had to ream it again.

Lovely! Ron W4BIN

Mr Pete I wonder if this project could be modified to be held in an Aloris tool post holder

You should remember, as I do, and since you are not that much older, that there was a “fair use” clause to the copy write law as it applied to education and educators. It basically said that as long as the material was used for educational purposes there was no infringement. I do not believe that Mr. Struck could have been prosecuted or warned to cease and desist from using the Atlas drawing since his product was designed for educators for use in instruction. The more likely scenario is as you alluded to: It just did not sell.

Couldnt an index plate be used in place of the gear?

hapy

is there a repository of similar project blueprints to browse for ideas?

@16:30 Did Mr Pete just imitate Mr Hankey?

Lyle, myheap is working on my phone today, so it might be a local problem.

Why is it that you can't run a reamer backward? Because it dulls the reamer, I heard that many times, but why does it dull the reamer?

I am disappointed that you are not making the knob in the drawings. How on earth do you knurl at 45° ?

"Old and incontinent." ? SAYS WHO! ...Tell them to go XXXXXXXXXXXXXXXXXXXXXX rusty wire brush XXXXXXXXXXXXXXXXXXXXTRAFFICXXXXXXXXXXXXXXXBUS BUMPER!.... Or not... Either way Thanks Mr.P! ..and don't forget to eat yer 🥦!..... and 🥞... and🍟🍔🍕🍝🌮... and especially🍩🧁!

Interesting how many of us have discovered no-spill paint cups for cutting oil. I got some a year ago, and I just noticed that Blondihacks uses them too. A product deigned for children, but useful to FOGs like you and me.
