There may be others wanting a box (or boxes) of the same size ?

Well I feel like a prize nana..!
The Sidcup machine shop was a step back in time to around 1863-alright, 1963, lovely vintage British made equipment and a small workforce who looked.. well, ..very experienced shall we say. One chap bolted up my platter to a faceplate and centred the spindle hole with a wheel gauge- tolerance was about 2-3 thou. He then measured the inside rim and tolerance was exactly the same... So my ding wasn't! Embarrassed to say the least. No charge so I left them some beer money....
Ahem false alarm, guys.
Spindle bush looks grotty- I could wire wool/polish it I suppose. Otherwise more isopropyl on the rim. Maybe I'll just keep it as a spare.
BTW I'd highly recommend the machine shop for any turning work- looks like they made the platter in the first place!
Cheers
Thomas

Well how bizarre, why is it "wowing" then?

Where exactly is this machine shop again?

Warren Engineering, Sidcup. They actually have a website.

i wonder then if the idler is slipping on the inside of the platter then? isopropyl the inside edge? i wouldnt have thought it was the idler or the bearing if it stops when the platter is changed

How is the rubber on the idler? I was having speed problems until I bought a new one off someone on ebay from Asia somewhere I forget where exactly but its a good copy and works well.

Slightly un-related, but a guy (in australia i think) made a lovely solid copper platter for his 301!

Expensive way to solve your issue though LOL.

Bluddy hell

Apparently it's been "bare" for a year, instead of painting it, could be lacquered to keep it shiny copper colour like

Well I still don't know...
Got a bit savage with some wire wool and isopropyl on the inner rim and spindle- my imagination or is it a wee bit better?
I see my other platter gets nicely 'stuck' to the bearing spindle as its a bit oiley in the platter bush- might put some oil on the iffy one as its dry at the mo'

Yes I would have thought of roughing the surface a bit to get a bit more friction.

Can you still get rubber solution these days? Maybe a smear around the idler tyre, make it more grippy

Are you sure it's not the rubber on the idle wheel this sounds just like the problem I was having and no amount of cleaning and buffing made much if any difference, it made a massive difference when I got a new idle wheel.

If it was a "dodgy" idler wheel one would think it would affect both platters ?
