Mini Lathe Reverse Gear Noise Problem Fix - Part 1 

Thank you very much!

Thanks mate, hoping to re-machine the tumbler gear detent shaft in the next few days which will hopefully sort it for good.

I should have mentioned, in part 2 I machined a new bush for the tumbler gear lever pivot, this reduced the reverse gear noise quite a bit. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-j4vh6xuiS0s.html

The camera angle made it look worse than it was, there was no danger.

Thanks for the feedback, will see what I can do for the future videos.

@@radboogie so I went on to watch your next few videos on this project and the way you are attenuating the machine sound and adding music is perfect. Thank you for sharing your project. 🙂

@@courier11sec thanks, we're evolving as we go 👍

Thanks for sharing your ideas Tim. I was really happy with the final fix at the end of part 4, and happy that some of the steel on aluminium bearing surfaces are now protected by brass bushes. But there are definitely quicker and easier ways to achieve a workable end result.

I made it from a digital Tyre Tread Depth Gauge. I cut it down a bit, made a brass slider to go under the scale which I could spring load, and 3D printed a housing for it. Here's a link to a similar one on eBay - ebay.us/36ZOND

@@radboogie you have video of making it

I don't have a video on making the "Tyre Gauge DRO" but will do one when I have time. Can upload the drawings and 3D files to the RadBoogie website if you would like to make one yourself.

Thank you. The mini lathe I have is the same as the Clarke CL300M, Amadeal of London do a tailstock for mini lathes that is compatible with the Clarke CL300M so you could look at that. I bought a Clarke CL300M fixed steady and that fitted my lathe perfectly. Amadeal say the centre height is 90mm, I just measured my lathe and the centre height is correct at 90mm. I would recommend asking them for some dimensions of the dovetail to make sure it will fit, to be sure. www.amadeal.co.uk/cgi-bin/sh000001.pl?WD=tailstock&PN=Mini%2dLathe%2dTailstock%2dwith%2dTailstock%2dLever%2dLock%2dAMA_SP_CJ18_138RB%2ehtml#SID=14

Yes, I usually put the lathe in neutral when not power feeding to quieten it down. In part 4 I drill an extra hole in the gearbox for the detent which makes it easier to put the thing in neutral and bypass the gearbox. I'm going to work on quieting the lathe down in future videos, will make an interesting project. Thanks.

Thanks Reaper. I tried what you suggested but it didn't fix the problem for me. Hopefully that can help someone else who has the problem - cheers for sharing.

It sounds worse on the video, mostly it's electrical whine from the motor drive circuits. I filter out the whine on later videos to be easier on your ear.

Much appreciated, i enjoyed the videos, with the sound off. 😂😂

True. You buy a Chinese mini lathe and use it to repair your Chinese mini lathe.

@@radboogie Yeah, it's a hobby in itself😆
