I'm looking for spacers, about 1/2 inch diameter, circular. 1/8th inch
thick with a central hole to clear a 6BA bolt, so roughly 1/10th inch.

Material to be smooth and reasonably friction free, so not rubber, but
plastic, nylon, brass, ali or something similar.

Any bright ideas? something commercially available? I've searched eBay
using countless terms, but the hole is usually too big, and I don't want
to sleeve. There must be something out there designed for something I
haven't thought of.

Well yes and no.

There are a lot of model wheels and pulleys that sort of fit the bill
but nothing without modification

OTOH this is not a hard thing to make.

From 1/8" plastic sheet.

Basically drill holesin some rough squares, bolr them together in a
stack, mount in drill chuck, mount drilling vice, spin and sand till
circular.

A lathe makes it even easier: 1" round bar in chuck, drill and then part
off 1/8" sections..

I made something similar for use on a pin hinge. Hole cutter of the rrequired diameter and a drill bit for he centre. I had some scrap polycarbonate sheeting which I used.

It depends how close a fit you want on the 6BA bolt. M3 is slightly
larger, so M3 x 12mm mudguard washers might have the right diameters,
but you would need a stack of four to get the thickness.

Thanks for all the suggestions. I was trying to avoid making something,
mainly because I'd bollox it. Having said that, they don't actually
need to be circular, and I have some scrap 1/8th perspex which may
suffice, cut into 1/2 inch squares.

Colin's suggestion is perfect. I knew someone would suggest something I
hadn't thought about. M3 12mm mudguard washers, 1mm thick is great,
because I can experiment with thickness using 2, 3 or possibly 4 at a
time. I have ordered a pack of 10 at £1.38 including postage.

Cheers!

Check Ebay for PCB spacers. Although they may be more tube than washer
shaped. You can't just use a few suitable washers to give the spacing you
require?

I know you said not rubber, but they are not rubber - tap washers?

Pick your sheet material and drill some 20mm holes with a hole cutter.

Obviously since we do not know the actual use I am tempted to that the
mechanical stability of anything turning on a 6BA bolt is not going to be
very good at all, hence the lack of washers of the needed type.
I was thinking about some engineering company who punches holes out of
ally, the bits punched out with some work and a hole drilled might fit the
bill if several were used together.

You say no sleeves, but in my experience, some kind of large chunky boss
shaped lump of brass for the centre and less robust washers around that
might be easier to source.

Yes, I agree, and the amount of 'stuff' available, following that model,
is staggering. However, to me it is worthwhile. Local ironmonger does
not have anything suitable, and an exploratory trip to B&Q et al is a
ninety mile round trip.

There are bugger all overheads with a operation like that,
particularly if they do enough volume so the mail operation
shows up every day to take away what needs to be shipped.

Somebody must be working awfully hard to make a living.

Not very hard at all IMO.

What was even more bizarre was a chinese operation that
was flogging some very decent plated nail clippers for just
1c, including postage, from china, presumably to get his
feedback up. When it turned up the jaws didn’t close
properly. I told the seller that and expected to have him
ignore me completely. But no, he apologised profusely
and sent me another which works fine.

Needed to space off some 40mm waste pipe on a tapering gap and the 15mm was
handy ;-)
