They're something he turned up for a job but didn't need, so not too sure what exact flavour they are.
It's not for a modern thing, it's for my GNthing

[Imagineering]

Is there any reason why I should not run bronze as the wheel spacers on my bike?
It looks pretty

Someone mentioned electro-galvanic corrosion. Not a problem with Bronze, don't use Brass though. Many pieces of Equipment have Aluminium Cast around Bronze then reamed to suit.

One of the Posters above has a good point regarding Sintered Bronze Bushes not having good Compressive Strength. Solid Bronze however, has a greater compressive strength than Aluminium Alloy.

Cheers. I'll look in to turning some up. Got to have sexy cheap parts

I'm sure you lot will have machinery using these or have had in the past. I have just bought an old lathe and am in the process of cleaning, lubing and all that stuff. I've cleaned up the drip oilers but the leather washers on those have seen better days and need to be replaced. I'm not too old that I can say I've never seen a leather washer before so don't know whether there is anything particularly magic about its use or rather it was what was available and affordable in a bygone era

My question - Can I replace with Fibre (or rubber I suppose) and should I ?

i can't visualise them in my head.


pipe cleaners.

you mean, oilers for the headstock bearings yes?

Yep, oilers for the headstock bearings like in the picture


The washers sit in the brass top and bottom caps to seal the plastic tube

[speights_bud]

Well so long as it holds the oil in side I don't see any problems

you have a set of hole punches yes?

just add a couple of "lace holes" to your bondage gear...


ps. that looks clean as hell. what are you cleaning??

pics or it didn't happen.

[Akzle]

sorry. pipe cleaners work in the cup-types, not so sure if they would in there...

Gaskets in the sight glasses? You can make them out of heavy gasket paper or cork. Or leather. Nitrile would be OK, but sometimes it slithers out from under the sealing faces. The trick is to not over-tighten them

The most reliable trick I've found is to make sure the faces are machined nice and flat and just use a thin smear of Loctite 518 or similar.

What's the lathe?

Not the sight glass (ie where you see the drip) but the resevoir above. Ill assume your advice applies anyway. Re what lathe it is. Not sure yet, i think its a colchester but it hasnt been confirmed. The previous owner didnt know and theres no naming or serial numbers visible.

One of these days ill get some photos up on the 'show us your lathe' thread and maybe the kb experts will be able to shed some light

Cheers

Yeh the leather ones are failing to do that unfortunately

peruse lathes.co.uk

the most cohesive list i've yet.

get the tape measure out, i bet mines bigger'n' yours!

I'll give you two modern options to replace the leather.
Sealing washers which are a steel washer with nitrile bonded on. Seal Imports carry a range and probably other places too.
Or make up replacements from urethane. I made up a set for a vintage Triumph rocker box which had pissed oil for ever. Top end is dry but of course the bottom end is still incontinent.
