Watching your various tool grinder videos , it makes me realize that they are from a bygone era ,same as nice manual machines. When I started installing CNC machines in the mid 80's (lathes and mills) almost everything was done with carbide inserts. Large bed tool grinders, if they existed at all ,sat nearly forgotten in a back room or corner of the shop. You are obviously enjoying your vacation , thanks for taking the time for another video😁

Very true. I mostly use insert tooling on the lathe and mill, so the Clarkson is only for making special tools and for solving awkward problems. It is a fun machine though.

Hi Andy. Anton has a proper surface grinder, so he already has that base covered. Those nodding head T&C grinders, are not really optimal for precise fine down feed, as you want on a surface grinder, but will do it at a pinch.

Very nice bit of machinery. I picked up a couple of design ideas watching this: the locking screw gear (raising mechanism) is perfect for a wing compass I am making and I will be adding a centre screw to my shop made hydraulic press ( I can see that being a big time saver). That press is also a really nice bit of workshop equipment.

What a lovely piece of kit. Seeing that stand, I seem to recall seeing one in the wild (the model and toolroom) at a place I once worked here in Blighty. Not having graduations or detents is not such an inposition as the craftsmen that worked them could probably set them up blindfold and by touch alone. We get so used to modern conveniences... Your mate has a nice looking shop there too. Thank him, and thanks to you for the insights and trip down memory lane.

If there are only three connections it is almost certainly in star already. Brook gryphon motors were supplied like this although this looks like a repair or rewind from the terminal lugs. Leicester was a centre for knitting textiles, and they also built masses of textile machinery and had a large machine industry. My ww2 Covmac lathe was rebuilt in the fifties by IL Berrige, a Leicester company whose main output was industrial knitting machines. The Covmac was actually built by P&C Garnett in Cleckheaton as war work, they also were precision engineers who manufactured textile machinery! There is very little history on the Covmac company itself. Phil

I guess the main issue it that these are 230V windings, and 3ph is 400V here. Going to a VFD is quite attractive, as it means he can supply it off 230V single phase, so it will be more flexible as to where in the shop it sits.

@@RotarySMP uk 3 phase is 240v per phase and around 415v between phases so it should be ok to run as is, but the vfd would provide speed control.

Ok so I watched the video again(Duh) and all becomes clear! The motor rating plate says 440volts, which has been sharpied out and the 240v delta connected written on the motor case which explains the non standard terminals on the cables. It should be possible to reconnect the motor in star so that it will run on 400v. In star there are two windings between each phase, in delta only one winding between each phase. So you could say that all three phase 400v motors have 230v windings and will run on 400/440 v in star and 230/240v when connected in delta. Using a vfd will work of course , just a bit more expensive, but less fiddly than reconfiguring the motor connections! I will now write a hundred times “ I must concentrate on what I am Watching”

One of my best memories of my youth was when I was a fireman in the Navy. As the engineering crew we get two less days of liberty than the rest of the crew, as it takes a day to shut down the plant, cool down the machinery and get it on shore power, and we have to come back a day early and start things back up one day prior to leaving. Lighting off the boilers, and getting everything back up to temperatures and pressures takes about a day, if you do it correctly, by the book. So if there are 4 days in port, engineering gets two days of liberty, and the rest of the crew usually gets 4 days. In the late 1980's, we made a visit to Portsmouth, England, and my first day in was refueling the ship. As a 19yr young buck, I was responsible for maintaining about 1 million gallons of DFM and I remember sitting with the boat crews monitoring the refueling with them. They offered me tea, and it was the first time I had milk in my tea.
