I need gaiters for my 1944 lorry rear axle swivel joints,

Does it have to look like the original ?

If not, what about something like a Unimog torque tube seal ? Plenty of images on the net.

Noticed that, is she OK or having a break, nice person whatever

Ok, plan F, I am thinking to machine a male and female mould out of Acetal / Delrin / Nylon / plastic so I can cast them in a two part "rubber" , I need 8 for my truck and a new best friend also needs some so a plaster mould may not last, wood is a possibility but it would need to be close grained, seasoned hard wood, and very messy to turn on my Colchester,

So has anyone got any "nylon" type material, thinking of round bar min 230mm dia and say 60-75mm deep, and a second piece say min 200mm dia and min 60mm deep, happy to pay (a modest amount) plus postage!

This is why they have to be split, and the flanges they fit over,

...it would need to be close grained, seasoned hard wood

I am not sure wood choice would need to be so restrictive. A stack of MDF might do, cover with a 3mm layer of epoxy or polyester resin, and turn to final profile. Plastic in that size is very expensive, probably very similar in cost to aluminium.

Wood is not messy to turn if you rig up a hoover nozzle near to the tool point.

Do you have a sketch of the profile? How are you to turn the curve on a metal lathe? It might be easier to rig up a tool rest and use some wood turning chisels.

One of the moulds would appear to need to be two piece as the gaiter has a bulge in it. You would have to assemble the outer two piece one over a solid inner one or assemble a collapsible inner one inside a solid outer.

A drawing of the profile would be most useful as then those who do metal casting could tell you what is the best option.

Aluminium would be cheaper than a quality plastic at those sizes

The moulds could easily be 3D printed, I've done a fair bit of this.

Generally the liquid rubbers are polyurethane, not particularly strong in tear resistance and vacuum degassing normally required.
