Started to repair the sub platter today.

First pic I'm setting up to centre the quill on the damaged thread. Milled the hole out 6mm and turned up a plug to fit. I've glued the plug in with permanent loctite. I figured the load is lateral so little to no force upwards on the thread.

Finished sub platter.

I was thinking of a resin bentonite plinth, I've heard good things, any body have one?

@warrjon

but the lathe is yours?

You could take the opportunity to brush the surface of the drum to remove the marks and scratches that time has given birth to and put the surface back to new.

Yes the lathe is mine.

I put the platter in the lathe today and polished the rim. I lightly sanded the platter top with 240 but didn't polish it.

lucky to own one and know how to use it.

Unfortunately, I always have to rely on external artisans who never have the time and desire to do private people some simple work, even pleading on their knees.

Maybe there's one of these near you, and maybe they have a lathe and/or mill.

Thanks for the info but I don't think that in Italy there are volunteer organizations that do what I need.

Some progress. I made 2 holes............. I figured it would be easier to mould the holes for the SP10 and tonearm instead of having to machine holes into the resin. I made a cardboard cover for the bottom of the SP10. This allows a little wiggle room to move the TT around to square it up. I have ordered 20kg of ISO resin which has not arrived yet so I made this with regular resin.

I decided to paint the SP10 black as I have some chassis black left over. I have an old caravan I used for storage which I used as a spray booth. Primer was sprayed with a rattle can and top coat I used the gun. As careful as I was with cleanliness I still got a bit of dust in the top coat.

I have the motor back together after cleaning the bearing and replacing the thrust pad and ball. The ball had a small amount of wear, but what was interesting was the ring around the ball where it seated in the bearing, you could feel the ring with a fingernail.

Nice job, but you could also paint it all over the frame so you didn't waste time covering some parts.
