A good while later I'm back. A day of boredome has presented itself so why not come here to sooth my noggin. Thanks bud. This works !

[@dennismasi9736]

Joe - you are the Michaelangelo of machinery. Awesome attention to detail, as always!

[@joepie221]

Thanks 👍

[@Gamerock82]

Joe, that is one of the prettiest parts I've yet seen you make / alter from plan. The real door / hinges was another. This is so much nicer than the "out-of-scale" screws would have been. Good choice and beautifully executed.

[@joepie221]

Thanks. I have a plan for the spindle too. I think you guys will really enjoy that one.

[@billgilbride7972]

U Joints are cool. Tiny ones are even cooler. Really appreciate the cutting order on the parts. Thanks Joe.

[@joepie221]

No problem 👍

[@lkw6640]

It’s really odd but, out of all the things I’ve seen you make, that’s one of the coolest Joe. It ranks up there with the power cross feed on the model lathe. At least I think it was you that did that. Pins definitely look better.

[@joepie221]

Thanks. this model is really full of interesting little details. I'm thinking it's one of the top 2 most difficult they offer.

[@jacqueso8424]

Another great video with shopgems for miniature work. Sensible, yet logical as well. Much appreciation for this and the multitude of other videos that you brought out for us. I dont know about the other viewers, but i am bound to certainly make use of these techniques for miniature work. Thanks again these satisfying to watch machining videos

[@howder1951]

Really neat part and some well practised technique, and it came out beautifully. Well done , thanks Joe!

[@brucelott3583]

If you want a good laugh, walk into a driveshaft shop and tell them you want it balanced

[@joepie221]

Priceless.

[@TomokosEnterprize]

Good day my southren friend. Good to see you this smoky day up here. Wild fires are thick in the valley.This wee drive shaft is just amazing. I can see the reason you weren't wanting to do this. Now that it is all together It is agreat lesson in small. Rounds and square featyres all working together and dead on accurate. Sure is a pretty thing in motion. On a different topic a good friend was breaking small taps so I made him your two small tap drivers for his birthday. He has always been heavy handed sort. About a week ago I stopped by and there they were, both had whole taps in them and he sends all his best to you. He hasn't broken a small tap since I gave them to him. Thanks a bunch Joe. Proof is in the puding eh. Take care my friend.

[@joepie221]

You're a good man Dean.

[@TomokosEnterprize]

@@joepie221 It takes one to know one old friend/teaching is a thing we are born with and you fella are one good teacher eh. Have a great weekend eh.

[@dondotson4604]

this is awesome! I hope to be able to do such things before I die.

[@jozefa1234]

Just amazing Joe. remember making an double joint for a model speedboat with 10 cc engine, all steel with steel bearing balls 4 mm and grooved couplings and a bar with small dimples at the ends for the bals to sit. only a lathe to do it and a small grinder. I would have benefit your videos at the time, 40+ years ago. keep up the very nice projects I love them

[@joepie221]

Thanks. I'm enjoying this one.

[@LeonardRoberts]

That looks like most all the shafts that drive the implements off of my tractor - less all the grease, dirt, grass. 😎

[@joepie221]

My first thought was.....HMM, should I make mini tractor??

[@swig46]

Two thumbs up for your design upgrade! 👍👍

[@cyclingbutterbean]

Breakfast with Joe and his magic tricks. No better way to start a Saturday morning. Thanks Joe.

[@joepie221]

My pleasure.

[@jamesdavis8021]

That is one of those jobs that make you smile.

[@joepie221]

When you are done and can exhale...yes. :)

[@mitchstephen5491]

Or make you cry

[@ShadonHKW]

Always enjoy your fixturing / workholding.

[@joepie221]

Thanks Stan. Good to see a comment from you.

[@stewanish]

Hi Joe thanks for the sharing as I will be making one for my mini mill that cuts metals.

[@ChrisB257]

I like this - a lot - nice set-ups and technique Joe with such tiny parts.

[@RalfyCustoms]

Way to go Joe, always a pleasure spending time in your shop, plenty of petrol heads passing by too by the sounds of it, thanks for sharing and best wishes to you and yours buddy

[@joepie221]

Its gray noise for me. I enjoy the launch junkies letting it rip.

[@RalfyCustoms]

​@joepie221 me too Joe 😂

[@warrior4christ777]

26:44 r u kidding me!😂 I'd have trouble making that full size. Great job A U

[@joepie221]

Thanks. This was fun.

[@chiparooo]

Beautiful micro machining! Excellent videography and close ups too. Thanks for sharing!

[@joepie221]

Thanks, Getting those shots is a real challenge some time. The camera position makes it very difficult to see and machine the part.

[@billchiasson2019]

Truly amazing work!! It's an absolute joy seeing you work your magic! Thanks Joe!

[@GenauMann]

Awesome work Joe🤙🏻

[@Ujeb08]

Very nice job Joe! Cool part/assembly . those pins are a big improvement over the original design.

[@joepie221]

Thanks, I think so too!

[@TheEvertw]

A work of art! Definitely better than the original design, but not for the faint of heart...

[@roadshowautosports]

Another aspect of machining that you bring to the masses is the shear necessity of fabrication of special dedicated tools for exquisite parts one may encounter, and that’s something you don’t get in school, JUST HERE WITH UNCLE PETE! Thank you!

[@joepie221]

Special tools and holding devices are an absolute must to get past some shop challenges. The creativity is up to you, just consider cutter access and stability. It doesn't have to be pretty ( but it helps :)

[@a.bakker64]

Love it. Huge improvement over the drawing. 👌🏻

[@joepie221]

The big screw heads just didn't look right.

[@samrodian919]

A truly beautiful piece of machining Joe, and as you say it looks far better and more accurate than those massive in comparison screws indicated in the drawing. Nice one sir!

[@joepie221]

Thanks, I agree.

[@rctrucktalk1149]

yet again another hit, great eye for detail and demonstrating a different alternate approach, good call, great result looks awesome. Awesome to see you back on this project.

[@joepie221]

Thanks, good to be back.

[@peteengard9966]

Very well done. Looks fantastic. I couldn't count how many U joints I have done in my nearly 60 year career as a big truck and mining equipment mechanic. The smaller the joint it seems to get harder. Little steering shaft and PTO shaft yokes would have the set screw 90 degrees from the yokes. If you get a tight joint, just bump the yokes where you put the 45 with a hammer and they'll loosen up nicely. Works every time. Keep up the amazing job.

[@glencrandall7051]

Outstanding! The precision is mind boggling.🙂🙂

[@joepie221]

Thanks. This little machine should be very interesting when its done. Lots of upgrades so far. ( not done yet )

[@TheZombieSaints]

Wow! Amazing little part! The pins were the right decision for sure. Well done. I'm subbing to see this little machine you're making.

[@joepie221]

Thanks. While you wait.. kzbin.info/www/bejne/j6jIiKZpftGjlc0

[@roberthiggins1142]

The changes that you made mak it look so much better than the as designed drawings, that is some awesome intricute miniature parts.

[@joepie221]

Thank you very much! I'm enjoying the build.

[@dr.zarkhov9753]

Beautiful piece of work Joe. Pinning it was the way to go 👌👏

[@joepie221]

Thanks 👍 I think I made the right choice.

[@ianlangley987]

Very well done Joe. I am a qualified machinist and I can only imagine the work involved. Excellent. Cheers Ian

[@joepie221]

Thanks Ian 👍. One feature at a time.

[@bscoffeeandwelding7236]

That is beautiful Joe this is why we are here ❤

[@sdrc92126]

I had no idea that it was you when I clicked the thumbnail. Good job

[@Dagonius.]

Great job! I was sweating too on that last pass. Looks much better with the pins.

[@joepie221]

Now I just have to remember which ones are the full length ones.

[@StraightThread]

Mesmerizing. 😵‍💫 Pinning it instead of screws is definitely a more elegant solution. It's very satisfying to watch your experience manifest itself in that part.

[@joepie221]

Thanks. I enjoyed the challenge.

[@richb419]

Hi Joe. I did the u-joints like the plan. I think they look good, but I'm with on the screws. mostly what I didn't like is soldering square tube into the newly machined brass. I changed the screws on all the kits I have done by PM. I did think of pressing pins into the holes. this mill is one of the toughest kits I have ever built. everything is done except for the disengagement arm. the crap they give you for the belting leaves something to be desired. Rich

[@howardosborne8647]

It would also work well with the cross pins loctited/retainer compounded into the outer ears of the yokes

[@joepie221]

Hi Rich. I went on amazon and bout black rubber bands. They look great and give you a lot of leeway for the pulley spacing. Maybe I should post links in the video description??

[@vandalsgarage]

Hope you had a good break, Joe. I'm glad your back, I miss these machining tutorials.

[@bradwallace5344]

Wow, impressive precision of a miniature joint. Fun to watch and inspiring.

[@michaeldurling793]

Joe, you never cease to amaze. Knowledge and wisdom combine to equal skill in execution.

[@joepie221]

Thank you.

[@paulsharpe3794]

Hi there I'm so impressed with your work I've subscribed. I can't wait for the next video

[@joepie221]

Thanks for subbing! I appreciate it.

[@markchodroff250]

Joe , that’s amazing, your the best ! Love all your videos

[@MartsGarage]

Fantastic job, Joe. I honestly don't know how you do it. The UJs came out really well.

[@joepie221]

Thank you. It reignited my desire to finish this model.

[@rufustoad1]

WOW I will never be this good but you sure are a goal to strive for!

[@joepie221]

Thats quite a compliment, Thank you. But never say never. I've had a LOT of practice.

[@johndevries8759]

Nice redesign and follow through. You live up to your own standards.

[@joepie221]

Thanks, I try

[@terryhooper7249]

This brings back my work in scientific scale manufacturing using 20BA screws a taping drill of .0142 diameter

[@samrodian919]

My brother used to thread grind those taps when he worked at LAL ( Lehman, Archer and Lane ) here in England. If I remember correctly they went down to 24 BA, which when I was young with good eyesight you could barely see the threads.

[@nutgone100]

Wow! I thought my work was small! I rebuild vintage magnetos & I balk at 8BA threads 😳(in fact that’s about the smallest I carry & only use very rarely, most of my work stops at 5 or 6BA).

[@andreventer3837]

Thank you Sir one more thing for me to do. Its a pity that I did not have you 50 years ago as a teacher.

[@TheDistur]

Amazing work. Those are some tiny u joints!

[@joepie221]

Yes they are!

[@williesnyder2899]

I have for decades now wanted to have a tiny HammerLok chain connector, working model!! Miniature hardware has its own fascination!

[@joepie221]

It does.

[@aubreymarsh2309]

I thoroughly enjoy learning from you and appreciate your skills!

[@rickrichards8811]

Okay, my mind is officially blown !! Great Job as always Sir !!

[@joepie221]

Thank you.

[@patrickfrantz2466]

Good morning Joe!

[@joepie221]

Good Morning !

[@magiclarry7688]

That is some amazing precision.

[@joepie221]

Thanks, I was hoping it would work out.

[@lagunafishing]

Double eye loupe standard Joe! Amazing work. 👍

[@mattomon1045]

great joints Mr Pie and I agree the pins look better !

[@grahammorgan9635]

Outstanding result Joe, great thinking and technique,

[@joepie221]

Thanks.

[@larrywiggins9946]

Great job Joe

[@joepie221]

Thank you.

[@Radiotexas]

Awesome, neighbor! Just awesome!

[@joepie221]

Glad you like it.

[@jdsstegman]

Man! Every time! The technique is amazing.

[@joepie221]

Glad you like it!

[@davidmyhre2720]

Hey Joy, That is crazy good stuff. Thank You for what you do.

[@aaronskoy957]

Adorable u-joint

[@abbassaigara3433]

Joe, you are simply the best. Thank you for the videos. Can you please show how you made the square hole?

[@joepie221]

The receiver feature was commercially available square brass tubing. Pressed into a round hole.

[@stumccabe]

Very satisfying - thank you Joe! PS your decision to use pins instead of screws was exactly what I would have done. A scale model with out of scale parts ruins the whole effect.

[@joepie221]

100% agree.

[@neilmaster785]

Great Job!!

[@StuartsShed]

Breathtaking. 👍

[@joepie221]

Many thanks!

[@andrewnormansell1518]

Superb!

[@metalshopwithtroy5755]

Very good job Joe, I found this video to be very informative. Thank you😊

[@joepie221]

Thanks Troy.

[@pa4tim]

So cool how you made a tool to make those round "things" for that cross coupling. I had no clue what it did until I saw it in action. Real magic.

[@joepie221]

it took a few tweaks to get the correct cutting diameter, but now I have it.

[@mog5858]

thanks for sharing. keep up the good work.

[@jimrandall9927]

Second time watching this video. Such great work

[@russelldold4827]

A thing of beauty!

[@joepie221]

is a joy forever....

[@haraldlonn898]

Just love to see what you do and how you do it.Thanks.

[@CreaseysWorkshop]

That’s just too cool. You make it look too easy!

[@joepie221]

Greetings John. This was more fun than I expected. This is turning out to be quite a model. Thanks for checking in.

[@billthompson3677]

absolutely amazing, as a machinist, i feel your pain , nice job Joe

[@joepie221]

Each piece was handled exactly like the first. Lots of tool changes. I'm glad I didn't have to make a dozen.

[@ls2005019227]

Awesome work! Thanks Joe!

[@paulsotheron710]

Phenomenal micro engineering Joe. 👍

[@joepie221]

[@dennisclapp7527]

Thanks Joe

[@mikestevens8046]

Wow WTG Joe. Good to see you back Mike

[@joepie221]

Thanks Mike.

[@mikepetersen2927]

Beautiful work! Very butt-clenching. Some of these model subassemblies are works of art all by themselves -- this one is right up there with that 4-jaw chuck you did for the lathe. Keep 'em coming, and thanks for sharing!

[@joepie221]

Thank you very much! I figure if I have to look at these forever after I'm done, I should give it 110% effort to get to the finish line.

[@Classicmodeler]

Joe, terrific video. I enjoy them so much. I am just starting out in machining as an added skill to my main hobby - model cars. Now armed with a Sherline micro lathe, 3 tools and a basic instruction book, how do I select the correct cutting tools, modify them like you do and expand the somewhat limited things I can do with a right, left and a modest boring bar? Want to make another instructional video for us noobs?

[@Kargoneth]

Guten Morgen, Joe!

[@joepie221]

Greetings from Austin Texas USA !!

[@joepie221]

Thanks, Many of the remaining pieces are tricky. Just about a dozen left.

[@mce1919A4]

Nicely done. Thank you.

[@joepie221]

Thanks for watching!

[@scottfarnham2717]
