Jones sockets - much used by the military and best avoided in my view - not the most reliable. They come in several sizes but I hate it when they are used for power.
Several military radios used them and they were a constant source of problems.
Lovely little machine.
Use MS connectors?
i looked at those but they are a bit spendy to replace 3 pairs. If I can find some good used ones I'll do it. In the meantime I'm going to buy a new Jones plug and re-fit those for now.
I got the machine together and ground my first part - just a random bit of stainless offcut. Seems to work very nicely and I got a good even finish..

Is this expensive?

When I got access to a surface grinder as a apprentice nothing was safe from tonsing up with a flashover, my 1930’s Colchester had the shiniest cross slide everFirst real job with the grinder - grind the grinder!
Here's the chuck it came with.

A bit battered and dented from too many tap-adjustments obviously with a steel hammer or something so I decided to clean it up. I stripped it down and gave it a good clean, stoned the mounting face to get rid of any burrs and then put it on my surface grinder and ground the front face flat. Only took a thou or two off.
After that I put it back on the cylindrical grinder but backwards with the fresh-ground face against the workhead spindle. This left a tiny runoff gap for grinding. I gave it a couple of passes and most of it cleaned right up, but a few dips remained.

I dressed the wheel and gave it a few more passes of half a thou each until the whole outside diameter was cleaned up nicely.

Once I was happy with the finish I put it back on the surface grinder to get rid of the clamping marks and put a better finish on the face.

Then I fudged a bit of a setup to re-do the chamfer, stripped the whole lot down and gave it a good clean again and assembled it with lubricated internals.
Looks a lot better now.
