Making suspension bushes
Anybody made their own suspension bushes?
Not the sleeves for them on the end of the wishbone, but the top hat bushing.
If so, what material did you make them from?
Nylon, PTFE, Oilon, Tufnol??
It will be for the haynes roadster design.
I know it is possible to get them from 3ge, but I would like to make as much of the stuff as possible myself, to this end I have ordered a small
lathe
I can get hold of polyurethane from polybush, but it's damn pricey.
Cheers
Sean

We machined our bushes for the wishbones from some material bought from RS. I'm not sure what exactly it is, I'll have to ask the person
who decided upon it and bought it and let you know.
With regard to poly bush material, I wouldn't bother trying to make your own, its a real a*re of a job. We spent ages trying to do it, spent
most of the time making the tooling and ended up throwing most of it in the bin. If you have a live axle/dedion that needs them for the trailing arms
I'd be inclined to by some pre-formed ones!

Some people have claimed success with machining poly bush material when freezing it first, at room temp it doesn't machine very well at all.
Normally polybushes are cast, which can be done at home if you can make the moulds - Alan B has done this.

I have been told this as well. It works for a lot of plastics, and depends on the hardness (shore rating). The harder materials can usually be
machined at room temp, anything softer than about 80 shore (roughly) needs freezing first.
I'll have a trawl through RS
Thanks

I could not for the life of me get the poly material to machine. Even when frozen for a weak.
