Another fantastic video and source for any Colchester owner! Thanks for posting. I will be doing this to my Mk2 very shortly! Wrote the above before getting to the schematic drawing in the video! Which is a superb piece of engineering by the way, but your explanation is even more so… thanks again!

“Dogs” They almost look the same as what is in an impact gun. Like an impact driver shaft/anvil and dog type setup . Fascinating to see how the nitty gritty parts on a lathe actually work. Cheers for this . 🙏🏻

Thank you. Congratulations, nice lathe!

Great video on the clutch, lathes with a clutch are really nice. The clutch here looks well-built and has easy access.

Yes, a clutch saves stopping and starting the motor. Good observation - I agree this clutch is well designed and made.

@@Workshopfriend I can use higher hp lathe on a house circuit using a lathe with a clutch. We have "smart" meters that measure inrush loads like starting electric motors and you pay extra for that, the clutch greatly reduces that.

IC. I didn't know that about smart meters!

Beautiful work. I have an old Colchester Chipmaster that is running the Matrix clutch and I wasn't sure how to adjust it so this was just what I needed. I bought my machine from a machine tool seller in Sweden after the previous owner passed away. He owned a prototyping shop and this was his personal machine at home that he had custom built by Colchester. It has all the metal plates written in Swedish and is a metric machine. Colchester made some lovely machines but all of them seem to leak oil no matter how much you try to keep them sealed.

Glad to hear this was helpful for you. Interesting to hear how your machine was custom built. Yes I agree; the screw cutting/feed gearbox on my machine seems to leak even though I installed a new gasket!

@@Workshopfriend My machine is a bit of an oddball as it has the newer variator and mounting plate design, yet the clutch level is the old style without the safety feature. It has a manufacturing number that put's the year of manufacture at 1964, however I think this was for the bed and not for the whole machine. I was lucky as I purchased it with a full set of change wheels and later managed to buy a Pratt-Burnered collet chuck and collet set, and fixed and travelling steadies. I wanted a Triumph 2000 but my workshop is too small for it. This is a video of my workshop - just to help you appreciate how enormous your is in comparison : ) kzread.info/dash/bejne/qGSB0rNtpaiaqrQ.html&t

Had much the same problem with the Matrix clutch on my Triumph. Lost count of the times I took it apart and cleaned everything as you did. On close inspection I noticed the lands on the inside of the drum were worn so I bronze welded them and turned them on the other lathe and re-shaped the sides with a carbide burr. This improved things considerably but I still find adjustment is a very fine line, one spline is enough between solid drive and release also going the other way another spline results in no drive at all. I got to a point where I was reasonably happy with it so will leave well alone until I can find out more info on them. I made up a spindle brake as the flywheel effect with the 12’’ 4 jaw is quite considerable. Found your video interesting thank you for sharing.

Interesting Steve. Good that you are able to do bronze welding. I have to venture in that direction. I found that my clutch will work over a range of adjusting nut settings (several splines' worth, I would say). I wonder if the taper on the lands is too steep - just going on the way the mechanism works? If I had the parts here I would measure the cone dimensions for you.

What a lovely design. You don’t find many things this well thought out these days.

That was a great explanation. Do you know if it's possible to purchase the 3 rollers anywhere?

@Workshopfriend

Sorry, I don't. When I dismantled the lathe for transportation to my place I noticed that one was missing. I later found the outer race (with rollers) trapped underneath in the stand. I had to knock up a new spindle. It was unhardened but has been fine so far. I wonder if similar size rollers could be purchased and retrofitted with longer spindles the way I did?

Hi , could you explain the pros and cons of a clutch vs motor stop/start, also did you have rust problems in Pakistan when you have cleaned the mechanism with solvent

@Workshopfriend

The starting current to an induction motor and load on switches can be high. Starting the motor once and using a clutch used to be a better solution before electronic control. Also starting and stopping can be quicker with a clutch (and brake if fitted). All this may be irrelevant if you have a VFD to control the motor, but still I prefer to use the clutch. I didn't use solvent on the splines or any other parts if the mechanism- just the plates. The discs are a stainless material.

suprized they didn't have wavy springs between plates to seperate them ,but too many parts less cost

Yes, perhaps you are right. On the other hand it seems this clutch has already survived 58yrs of on and off use!
