- Ep 29 (Cone Clutch FAILURE !!!!!!! Modification) Make a Micro / Mini / Small / Watchmakers Lathe
#modelengineering #howtomake #machines
Here showing Modifying the Clutch after failure
This lathe was briefly started many many years ago by an unknown Engineer, passed through a few pairs of hands since with nothing else done to it, until i got hold of it, so i will continue with the small amount of work already done, to finish the lathe in to a Imperial Micro / Mini / Watchmakers Lathe with screw cutting capabilities & back geared, everything has got to be made from Scratch including the Back Gears, Clutch, Change wheels, Leadscrew, Tailsock, Spindle, Pulley's, Screwcutting Mechanism, Dials etc etc just to name a few. The casting is very elegant and well made item, with a good foundation to start from.
There were numerous manufactures of these small lathe in Great Britain many moon's ago, to many to name here, so do a search and take a look at the huge seclection of makers and differing shapes, sizes and capabilities.

Impressive stuff. I like the 'I'll just make another out of aluminium' -that'd be a three month project for me! Cheers Kev. Looking forward to the next part 👍 🇬🇧
cheers Matt
yes i wasn't over the moon about making another but sometimes you have to just bite the bullet, it works great so got a spare one now for when i make another lathe🤣🤣🤣🤣🤣🤣👍👍👍👍👍👍👍
thanks for feedback

Gday Kev, you can’t ask for much more than that mate, that was a clever modification. Cheers
cheers Matty.
works great now, very pleased
thankyou👍👍👍😉

Excellent fix on the clutch Kev. I'm very much enjoying following this build. 👍
Thanks 👍Olly
Soon be time for a cast iron stand and a naming ceremony just a few more episodes
cheers
Kev
Hi KEV
There's no doubt that this modification is effective. Good work
Have a nice Sunday

Many thanks Olivier
yes much better, would pull a car now!!🤣🤣🤣👍👍👍👍👍
have a nice day

That cork has done the job Kev. Great idea for the clutch. 👌👍👍🚂🚂
Thanks 👍Mike
Hit lucky the first time.
many thanks
see you next time

Pure wizardry as always. Thanks for sharing Kevin.
Glad you enjoyed it Matt
Not sure about wizardry, but i will take the compliment, thanks very much Matt
see you next time👍👍👍👍👍👍

When you first started talking about it I was thinking maybe leather but the cork worked really well. Lovely job Kev 👍👍👍 Cheers, Alan.
Thanks 👍 Alan
great minds think alike😉👍
If i had room for a stronger spring i would'nt have needed to do this, but it works great now, soon be making chips after a few more episodes and a naming Ceremony😉👍👍👍

Great fix/modification and easy maintenance no or very little ware n tare on your surfaces.
cheers John
if at first you don't succeed try try & try again
Spot on now
many thanks👍👍👍👍

Great job Kev. IMHO, the aluminium cone looks better that the bronze one, but then I always have been a fan of contrast...
cheers mr & mrs t
yes contrast!!! can't beat it !!!, saves me a job !!!😄👍👍

Kev
Good one. That seems to work just fine.
Thanks 👍 Michel
2nd time lucky, sometimes you have to fail to succeed !
appreciate the feedback👍
Kev
Nice result there. Great work!
Thanks 👍 Stuart
luvely jubley!!! problem solved
P.S. Got your sticker thanks very much will a do a shout out soon
have a nice day👍👍
Kev
The other thought I had. Was a clutch of a chainsaw. Which works centrifugal as the power increases the weights move through springs to take up the drive. But it’s how to adapt it to work. Just an idea. Good video enjoyed it.
Great point! A👍
Maybe next time 😉😄👍👍👍
This one is working great now, so my moto is if not broke don't fix it, but i will keep your suggestion in mind for a future lathe
Many thanks👍👍👍👍
Kev
@@MrFactotum Centrifugal clutches require a certain minimum RPM to engage so I don't think it would work too well in this application
Well you made a brilliant job of the clutch there Kev.
Well Done

An interesting fix Kev. I guess if the cork wears it will be easy to replace. About two years ago I fitted a s/hand clutch to my
Myford. The moving part is bronze, and closes again the cast pulley wheel. There's also a strong spring inside the counter shaft. Fun to fit, but I wouldn't do it again! Cheers Nobby
thanks Nobby,
yes i modelled on a myford clutch but couldn't find a way to fit a strong spring due to space restrictions, otherwise it would have worked okay, you live and learn!!! but it works great now.
appreciate the feedback, i've still got to catch up on your latest video.
Regards
Kev
Great fix! I believe in days gone cast iron was after used for cone clutches though I wouldn't know if it would be better than bronze. I guess it primarily depends upon the length of the cone with respect to diameter and spring pressure.
Hi Nigel
Yes you've got it, a stronger spring would have done the trick Nigel, but no room,
i initially thought with the micro forces involved it would have been enough friction, but you live and learn. I will know now for the next one😄
see you next time👍👍👍👍

Kev
Looks like a safety feature Kev 🤣 I wonder if it’s the angle that was the problem? Myford use a similar idea for the clutch with metal to metal contact with brass or bronze. I’ve never taken mine apart though. Great solution works really well 😀
Thanks Julia
i modelled it on the Myford but with being a small lathe the spring wasn't strong enough and no room to get a stronger one in, but it works great now
cheers👍👍
Kev
Hi Kev. That was a well thought out solution which definitely worked out very well for you. Brilliant result. 👏👏👍😀
@@andrewdolinskiatcarpathian Thanks very much Andrew, works great now. See you next time, Kev
VERY interesting video Kev. I never gave the fact that you used bronze for the clutch much thought, but I can see now why it was a bad idea. Bronze is naturally slippery. The only cone clutches I've had any experience with were either vintage car (cork faced cone with cast iron receiver) and cylinder type lawn mower (cone and taper receiver mating surfaces both bare cast iron). I would be inclined to leave the aluminium cone in place as it will have much better heat transfer/dissipation than bronze and should preserve the cork longer. Looks OK as well. Cheers Rob
cheers Rob
Yes it works great.
I used bronze because if you ever get bronze bearing grab tight on a shaft you can't move it for love nor money, it would have actually worked if i could have got a stronger spring on, but with everthing being so small and tight for space i couldn't manage it.
Anyway it works great now no slippage with a 600 mm long piece of stout timber levering on the chuck, Solid as a rock👍👍👍👍👍👍👍😉😉
many thanks for your thoughts, appreciated
regards
Kev
What a corker of a job Kev!
cheers Tom
wouldn have been more of a corker if i'd have bought 6 bottles of wine to get the cork🤣🤣🤣🍷🍷🍷🍷🍷🍷😉👍👍
take care
Kev
I don't wanna sound rude but bronze on bronze makes for a terrible clutch as bronze is a bearing material and quite a good one a that so choosing it for a clutch seems quite stupid to me
Clutches are usually cast iron and some friction material as the coefficient of friction for cast iron is relatively high when paired with something softer like cork or clutch padding or break pad material which the best I know of is sintered cast iron I believe (like the ones in tractor clutches)
or if you would really want a bronze clutch without any friction material you can always make the angle shallower tho that might result in a clutch that can bind if the angle is too shallow
hiya Cj
It's okay i have a thick skin, so thanks very much for your interest.
Bronze is a brilliant bearing material if lubricated, if dry though it sticks like s---- to a shovel. It would have worked with a stronger spring to pull the tapers together, but being a micro lathe i had no room for stronger spring, but all good now and it works great.
Many Thanks for watching and feedback much appreciated.👍👍👍😉
cheers
Kev
@@MrFactotum Really? I never seen it do that although it's true I never put 2 pieces of bronze together under pressure. I assumed it would be bad cuz of it's bearing properties. I forgot I wanted to suggest just making the disk from aluminium as it's soft and doesn't have the best bearing properties unless very well lubricated or with anodized
Anyways thanks for sharing your knowledge.
@@Cjarka_ cheers Cj👍👍👍👍
it's good to share off different peoples ideas, were all learning on that never ending learning curve all just at different points on the arc.

A good result Kev. Very Myford like . Nice. Did you receive the little chuck yet.
Steve.
Thanks Steve
No not received as yet, is it Royal Mail or Evri,
No rush though, sometimes things come next day, sometimes takes a week
Thanks again Steve i will let you know when it arrives👍👍👍
cheers
Kev
@@MrFactotum Hi Kev . Sent with Royal mail. Posted last Sunday evening.
@@Steviegtr52 ok Steve thanks i'll let you know when arrives👍👍👍👍
@@Steviegtr52 p.s. also a bank holiday Steve👍👍
@@MrFactotum Ah yes of course. I just hope it is of some use to you.

We're you a fitter and turner or did you learn your skills as a model engineer as Poms are famous for ?
Use to read model engineer books back in the 60 d and 70 th . Was always fascinated.

i was a machinist / fitter / toolroom / drawing office and supervisor till the place was shut down by Maggie Thatcher and her cronnies, you get the drift.🤔😄👍
