Machining a miniature Lathe - The Backgear Mechanism

[@esrAsnataS]

Never gets boring, I love watching skilful people.

[@joepie221]

Thanks.

[@garthbutton699]

I have learned from you so many detailed machining steps,tips and tricks,thank you once again for taking the time to produce these videos.

[@joepie221]

Glad to do it.

[@snappers_antique_firearms]

It would be really cool to do some thread cutting with this tiny lathe

[@johnsims5330]

Whitworth, or Apex? :D

[@joepie221]

There is no lead screw, just a drive shaft. I don't know if its possible.

[@BedsitBob]

@@joepie221 It might be possible, by reversing the lathe, after each pass. Or you could add a lead screw and threading dial. 😁

[@snappers_antique_firearms]

@@joepie221 I would love to see you add a lead screw. If you feel like that's something you want to do. I am guessing you could just use 60° screw because the force so low.

[@Andrew_Fernie]

@@johnsims5330 B.A. 👍

[@stevegreen2432]

Hi Joe, As a retired clockmaker, I would not put flats on that center shaft until after you have the mating gears made and fitted. That way you can use the etcentrics to adjust the depthing of each set of gears individually . If the center shaft is slightly out of line as a result it won't affect the operation . All looking good--thanks for the video

[@douglasharley2440]

yeah, he said he's gonna put this shaft flats in later.

[@joepie221]

When I can accurately judge the position of the handle, the screws will dictate where the flats go. If I rush into it, the handle may be in an undesirable position.

[@stevegreen2432]

@@joepie221Hi Joe, In the end, I doubt you will need any flats at all--there will be so little pressure on those parts the screws won't be that tight. This has to be the best series of Videos I have ever seen on machining mating vees---many thanks.

[@rexmyers991]

Well, I’m subscribed (long time) and as a very amateur machinist, I look forward to my ‘lesson’ each week. Thanks, Joe

[@joepie221]

Awesome, thank you!

[@MichaelLloyd]

It's hard to imagine just how small this stuff is until you see a finger next to it. Nicely done as always

[@joepie221]

Thank you.

[@neddo66]

Joe you NEVER cease to amaze me with level expertise in your work and the years of experience is truly outstanding keep them coming

[@joepie221]

Thank you very much.

[@TomokosEnterprize]

Once again you put the numbers to work ahead of time. No point in not doing that footwork ahead of time. Seeing the brass now is great. Poor man's gold eh, LOL. Lots of people don't like working with brass. Sharp, sharp tools and a gentle approach has always worked for me. I am thinking we need to give you a nick name. "Joe the executioner" as yer killing these parts my friend.

[@joepie221]

To add....I like HSS for brass. Carbide has just never given me the same finish. K68 grade carbide maybe, but I always reach for my HSS tooling for brass.

[@TomokosEnterprize]

@@joepie221 Absolutely and I always hone my high speed. It seems we just can't get carbide sharp enough. I suppose that is why steel is used for medical scapples.

[@miles32323]

I've been a subscriber for about 3 years now and i've learned so much from you. I don't run a lathe at work but i do enjoy all of your videos. Thank you Joe.

[@joepie221]

I appreciate that

[@cavemaneca]

Perfect fit as usual. Looking great, it'll be nice to see the spindle in there with the gears turning.

[@joepie221]

It will. I may modify it to suit my thoughts.

[@terrycannon570]

Excellent. Joe again I learned a good tip. "When machining small diameter's in the lathe start at the chuck and machine out" Little bits of information like this put you on the top shelf with the pros. Thanks a million for sharing with us. BTW I have been a subscriber for a few years and a Patron supporter this year.

[@russelldold4827]

No arguments with your admiration, just to add that Joe is that rare breed - a professional who is not afraid to share the special techniques gleaned from a lifetime of experience that shine through in his work. Thanks for sharing, Joe.

[@joepie221]

When trying to determine where an angle will run off a part, and still maintain a specific root diameter and length, starting at the chuck is the way to go. If everything is known, you should always work towards the weakest feature. That usually means working to the chuck.

[@terrycannon570]

@@joepie221 Now i am confused

[@dougbriggs6797]

Your quick tips for finding edges and centers are so much appreciated. Also, the aluminum in the bore while drilling is fantastic. I learn something in every video.

[@joepie221]

I didn't want to hit the backside of the hole and that wire trick works well.

[@TrojanHorse1959]

Awesome! Another step closer, great work Joe!

[@stevekibbie6198]

Another great installment! Looking forward to more!!

[@joepie221]

thanks. Me too.

[@DonDegidio]

Hi Joe, Another display of fine workmanship. Nothing better than watching a master craftsman at his trade. Won't be long now before see it making small chips. You and the family stay safe.

[@joepie221]

Thank you for your continued positive comments. You and yours stay safe as well.

[@richardsweet5853]

As always, a beautiful job Joe. That will be a true masterpiece when it is finished.

[@joepie221]

I've always admired miniature machinery. Thanks.

[@johnmcclain3887]

I came into "the machinist's world" as an engine mechanic, learning the machine work rebuilding engines. I've done it fifty years but have gotten good value in seeing techniques and processes that I never got in my one year of "machine shop". I love the use of the razor blade, been doing it by feel up till now. That looks very fine.

[@joepie221]

Thank you.

Phenomenal as always Joe. I bought one of these kits because I know I could follow all of it. U are extremely detailed in ur descriptions and the finished product is always spot on. Love ur vids man!!! Keep up the good work! I’m just a garage machinist but always inspired by ur work! I always learn watching u. Every freakin time!

[@joepie221]

Show and tell videos are fun, but I always try to give you something to take away. I'm glad you get it.

[@robertmont864]

Challenge I have spent a good bit of my time watching you make that little lathe, when you are done making it, you better make some chips with it. Thank for your excellent videos.

[@lennym1273]

I second that...

[@joepie221]

I will.

[@philiphoeffer7442]

Awesome work as always Sir. :)

[@brucematthews6417]

Some examples of hints given in the past and a few new ones. Your videos are always educational well over and above the actual project being machined. Lots of good hints here too. The use of some soft wire to feel the drill break through is a keeper just as one example. I like your idea of flats on the inner shaft. Not only to avoid the burrs but also if you "dull" or flatten the ends of the set screws and make the flats in one go so they are in the same plane or at least parallel then the offsets will automatically clock to the proper angles. And that means the back shaft stays parallel to the main shaft. And that's obviously a good thing.

[@joepie221]

The flats will help for sure.

[@TheTacktishion]

Once again.... I was holding my breath when you machined the handle on the end of that 3/32" shaft. I just KNEW it as going to climb that cutter.... You are a lucky man....! Good work!!!..

[@joepie221]

I was expecting to climb over as well. I normally cut the other way.

[@bigalremington]

Absolutely amazing.

[@johndevries8759]

I like the idea of the flats on the bent shaft to keep the two eccentrics in time with each other and allow disassembly without issues. Nice job Joe, you've got a lot of time in this little model and it shows. J

[@joepie221]

Thanks. I'm thinking about the bull pin at the moment. They used a set screw and I'm having a hard time going down that road. Space and installation sequence offer some challenges.

[@ikkentonda]

I’ll take the over on Joe re-making the cracked part before the series is finished! And that indicating tip with the eccentric bushing was brilliant - precisely why I never miss a video.

[@joepie221]

Thanks for tuning in and yes, I'll probably make a new shaft.

Thank you.

[@michaelclark9409]

"...Ream two bushings with one hone..." I like it.

[@joepie221]

That worked well. I should have also done both tapped holes in the same setup by just offsetting the X axis.

[@ferrumignis]

An oil hole in the back gear shaft would be a useful addition, no way to get any lubrication in otherwise.

[@joepie221]

I may add a few small holes or slots. Thats a solid suggestion.

[@danieldunham9978]

I can't imagine why people are not subscribed! As always awesome work can hardly wait for the next installment!

[@donstieben3939]

i would make the gears have a spoke center or holes so they look like a casting instead of just a blank sawed off from a piece of stock. thank you for all i have learned from you, its been a great help getting started in machining

[@joepie221]

Holes to make them look like sprockets would look good. I did consider it. I still may.

[@monadking2761]

I'm so amazed of what you do. I would screw it up so quickly. .001" press fir on brass .250 In diameter I would bend it right away. It takes good tooling to do it right and you have the patience to do it right too.

[@joepie221]

I think patience is a big part of a build like this.

Joe, if you don't at least set this up and turn some small bit of SOMETHING I swear I'll unsubscribe ! ......

[@1crazypj]

Putting flats on shaft is a good idea as it makes it simple to 'time' the eccentric and make sure gears are not tilted and shafts stay parallel. 30+ years ago Kawasaki used eccentric chain adjusters which seemed like a great idea but could be a PITA to set accurately. It made a difference on a 160+mph bike if wheel was tilted or out of line slightly (I guess 99% of riders didn't notice a couple of mm misalignment 13"~14" from axle though and rarely if ever checked out top speed)
