Modifying lathe half nut mechanism

[@nrml76]

That is one ridiculously over-engineered rotary tensioner. I absolutely love it! What a fantastic project👏

[@hammerland4028]

Thank you

[@vandalsgarage]

Amazing, as always. I'm gobsmacked by what the creator of this channel does with the most basic of home shop machine tools. It's proof that you don't need a Monarch lathe or full sized Bridgeport or Deckel milling machine to make quality parts. I've been a fan and a subscriber ever since I saw the first series of mini lathe upgrades. Proper job, mate.

[@eddietowers5595]

Awesome as always. I have to give you extra points for using additive Machining parts for a subtractive machining projects. Because you made the part, that make the parts, to make parts. Two thumbs up. This thing is going to be as precise as a Swiss watch. Great job.

[@BeachsideHank]

Beautiful work, mechanism is now on the "clean" and serviceable side, good fusion between 3D and traditional fabrication, well done good sir!

[@hammerland4028]

Thank you

[@KR-Roland]

Very clever design ... and I think that a few people aren't realizing that the mechanism is always trying to close just that last bit by itself, no matter at what point you close the handle ... without this design, the operator has to 'feel' when the nut will close all the way, keeping pressure on the handle, and only then will a ball go into a detent recess ... what a beautiful job ...

[@Reman1975]

Sometime, "OVERengineered" is just the right amount of engineering to throw at a problem. 😁 Beautiful work there mate. Personally, I'd have found it hard not to solve the problem by making a simple ball detent with a similar diameter to your finished unit, but then again, my solution wouldn't have been beautiful enough to warrant a display window to show off all the prettiness within. 😏 It's always satisfying to see someone implement a technically interesting mechanism. I'm almost getting the feeling that you might be a design engineer for your day job, but by night you retreat to your home workshop and make the intricate things you'd love to do at work, if it wasn't for management constantly saying "You've got to keep the parts count as low as possible". 😣

That is a beautiful mechanism! Almost a piece of art! I like it very much. Someday I have to address this on my machine as well. Thanks for sharing, really relaxing to watch your videos!

[@hammerland4028]

Thank you! Great to hear from you

[@diso41]

What can we say ????? perfect engineering performed by a top master. Congrats!

[@jasonh3109]

Absolutely beautiful. A work of art. Thanks for sharing.

[@pgiamel]

Fantastico, studiavo da diverso tempo il sistema per risolvere lo stesso problema, Grande idea !!!👍👍👍

[@keithbaker8212]

That is a very unique idea and awesome workmanship

[@lohikarhu734]

very pretty cinematography, as well!

[@mrvector257]

These minilathe upgrade videos are great

[@CoolIdeasDIY-qv1nz]

Great work colleague!

[@philhermetic]

impressive! Extremely good work!! Phil

[@hammerland4028]

Thank you! Dima)

[@kris79802]

perfect workmanship

[@1crazypj]

Very nice project, impressive design. Did you remove apron and check if lathe had any adjustment screws? I did mine probably 18 years ago, can't remember exactly how I fixed the excessive clearance on half-nuts but I do remember they were adjustable.

[@michedmck]

Excellent work!

[@josemoura8691]

Parabéns! É um jovem que pelas mãos parece ter em torno de 20 anos. Parabéns pela criatividade. O futuro te aguarda.

[@stuartcox4739]

That is a piece of art right there 👌

[@lohikarhu734]

i like the idea of scribing the middle with the tool tip, as you know, by the center 'pip', if any, that the tool is exactly on the midline.

[@renetr6771]

U can easily check, if your tooltip is on the middle, when u turn your spindle around 180° and draw another line. I do so also on my cnc lathes.

[@немытаяжопае]

Уважаемые, резец уже выставляется по центру детали.

[@georgecurtis6463]

I just cleaned things up, marked the position of the shaft where the ball sits, put a new dimple there and now it holds the half jaws securely. No looseness, no popping out.

[@rickpalechuk4411]

👏👏👏👏👏 Big golf clap! Just love your channel Cheers

[@hammerland4028]

Thank you

[@larrykent196]

That is one clever lever. Cheers!

[@timmontano8792]

It looks like you could have just as easily 3D printed every component except for the bearings and the springs. What type of filament did you use to print the housing?

[@drd1924]

Nice mechanism!

[@WayneCook306]

Nice Job. 👍👍👍👍👍👍👍

[@hammerland4028]

Thank you

It's like watching a jeweler...😂 beyond my skill set but very entertaining!🐬

[@0ADVISOR0]

Awesome! And 3D Printing ftw!

[@hammerland4028]

Thank you

[@Pushyhog]

been here couple years or more,even l learn stuff, using modified mini lathe.

[@EitriBrokkr]

What an obsurd amount of work for a detent

[@tonyleathem]

I don't suppose you have the measurements and gcode files for this do you

[@josseman]

Amazing! Do you have drawings?

[@hammerland4028]

Unfortunately I don't have drawings, only Stl of a plastic part

[@coenduc]

Damn good skils .

[@mighi68]

Super Qualität des Videos - wow

[@thomasmica2856]

Отличная работа!

[@peoplepower1272]

Can't really see this solved anything. You can see the halfnut still won't engage every time without jogging the carriage handle. Same old problem...

[@carlmcferran9371]

D mo not see what this’d mod is supposed to be doing ?

[@VanFlausch]

Brilliant!

[@ПетрИванов-ы6е]

Nice project. I doubt the plastic body will live long.

[@hammerland4028]

3D printing time is only 25 minutes)

[@Mishelovka]

Но ведь там уже есть примитивный "узел" регулировки, зачем этот сложный механизм? Если только для контента...)))

[@britenrhodehouse8692]

Cool!

[@ВладимирИшков-г6б]

Элегантно!

[@НиколайКрымский-б1л]

- почему так сложно? - потому что я так могу

[@hammerland4028]

Так и есть, проще придумать не смог

[@steveforbes8287]

Absolutely brilliant!

[@АлександрФедоров-г8н]

Немного усложнил но прикольная задумка

[@sky173]

That's awesome, but I have a real hard time seeing 3D printed plastic parts on a machine lathe. Regardless, great job.

[@joell439]

👍👍😎👍👍

[@waliza001]

why make something simple when overcomplicated and overengineered also works fine :)

[@williammorris1763]

Needs more drawing board before commitment. Nice mechanism though, quite fancy.

[@hammerland4028]

Thank you

[@peterpan7903]

Couldn't you just readjust the existing mechanism? Perhaps the detent of the lever was not optimally adjusted or the spring was too weak.

[@shawnmrfixitlee6478]

that is so cool. I need one .. I would pay you $100.00 if you make me one ! I am serious..

[@Pushyhog]

id pay 300$ for one.

[@hammerland4028]

That's almost the price of a lathe))

[@mk6595]

Nice. But I have to deduct points for using a 3D printer.

[@hammerland4028]

Thank you

What a waste of engineering

[@quinto3969]

No rigidity. Plastics have no place there. 3D printed or not.
