Superflex look like the type of company who may be interested in making some PU bushes for the steering arms, seeing as the OE G40 version is obselete now.

PeteG40

they do - but i emailed them and never got a response.

Same for PU engine mounts or rear axle bushes.

Money talks, so i think we'd need to get a group buy with confirmed numbers before Superflex might start looking into tooling, moulds etc.

well I did say that we have a number of people willing to test a batch and a significant of interest in the engine mounts at least.

depends on the hardness of the poly really..

You can machine polyurethane no problem, its like cheese. Whatever grade it is it certainly wont be too hard to machine. The most annoying thing is that it dosent break up as swarf and it all wraps around your tool. Surface speed want to be around 120 m/min and you want a very sharp tool.

Thats what i`m on with Tommo.

We recently got hold of a Harrison T300 Lathe wich is a godsend to my
Myford super severn.

I hadn`t done any Real Lathe work since school and got the Myford about a year
and a Half ago.

Learn`t alot with it and feel comfident enough to have a go having made Pulleys,
Some lovely steering bosses, Threaded parts, allsorts really.

The Harrison is a Really good Lathe and is a lot easier to set up than the Myford.
Did screwcutting on it last week with success, though i practiced on alloy 1st.

Got to know a man at an engineering firm in one of the units near to Taylor bends
where i sometimes work and he is at his Colechester Lathe day in day out and
really knows his stuff.

Chatted to him about it and he gave me a run down on machining Rubber, Nylon,
Poly and the likes.

We have the gear so may as well have a go.
Does anybody know what they use to make the moulds as i wondered if it was
possible to machine those as well.
