The covmac LIVES! Got it finished Friday afternoon. As an added bonus, everything works, ran through all the feeds and speeds, and it's all good. Did a meticulous clean of the three jaw backplate thread, oiled up the nose thread, and fitted it. Interuptions notwithstanding, on Monday I will be finding a suitable pump from my collection, for the coolant system, and looking at making the missing hinge block for the plinth door, and then it will be truly finished, and fully usable. I will combine the pump search with a tidy up and general sort out of my "stores" which contains quite a large quantity of stuff which will be bound for the scrapyard, which gives me a chance to go poaching for materials! Hope this link works!

Well done Phil.

I don't like to be critical, but was there an element of variable speed running in the higher speed you demonstrated?

Next test of course is to make some swarf.

Best wishes Woody

yes Brian, very keenly observed! it was a bit variable in the higher (lol) speeds, and I had noticed that the lathe was harder to turn manually than I would have expected, when turning the input pulley, so I need to check the clutch, and check the freeness of the headstock. I took the cap off the headstock to observe the oil splash, and got a rather closer view of the oil splashing than I would have prefered! After I had cleaned it off the wall and me, I drew the conclusion that the oil was somewhat sticky, and may be part polymerised, so a good warm up and oil change is on the cards. I think from checking lathes site that the headstock is all bushes apart from a ball thrust bearing, and it gives me an excuse (as if I really needed one) to take the top off the headstock and have a look. I found all manner of spare parts in the bottom of the Colchester headstock and once I am happy with the Covmac, I will be stripping the colchester headstock (which I think is noisier than even a Colchester headstock should be, and has had the  bearing adjustment nuts "messed with") with a view to changing some bearings, including the main spindle bearings, which I was lucky enough to get an immaculate set of for reasonable money, and if I need any bushes or spacers making for extracting the bearings, I can make them on the Covmac. Onward and upward!
