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

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 :shock:


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 ?
