What's people's thoughts on DIY Bushes then?

Not sure I'd try to do my own for suspension but for the cost of the polyurethane bottles is it worth having some on the shelf for non structural stuff like exhaust hangers as in the thread etc?

Just saw it and thought I'd ask :?

I have done it before but used some stuff by prc desoto. would be interesting to see if it's any good as judging by the article in complete kit car this month the stuff you don't bake is shit and powerflex use a different pu that is cured in an oven.

Sounds definitely like non structural use only then, unless someone's willing to be a guinea pig? :lol:

We are currently working at the Camberley rubber company and if you could see the proper process used for making bushes you would know that the air dry stuff has to be below par. I am there again next week so will take some sneaky snaps of the machines that make the proper stuff.

Here you go then chaps, this is how proper rubber/silicone products are made.

This is one of the machines that injects the rubber into the mold, the raw material is pulled into the gubbins on the top left hand side of the machine where it is heated to melting point and then forced into the tooling by those massive rams.

Image

The tooling plates are machined from solid billets of steel , some of the trick ones are in excess of £250,000.

Image

This place has about 20 of these machines which sometimes run 24 hours a day seven days a week.

One of the products prior to trimming.
