Cheaper Bushes???
I was just loking at the powerflex web site at top-hat bushes. £13.95 each!!
Are there any cheaper options?
Someone once mentioned bushes for only 30p each on this forum. What are these? Where to get.
Would anyone recommend buying rods of bush material and machining? What is the best material to use? Where would I get such material?

there are a few folks on here and one company i know of (MNR ltd) that would knock you up some custom bushes for beer tokens.
Or if you have the facilities yourself then you can buy Acetal for very stiff competition type bushes or there are other materials IIRC nylatron???
for a more compliant material, these are readily available on Ebay or maybe cheaper at a local plastics supplier.
Both of these materials could be turned by the home machinist if you have the right equipment.
Juat remember you need the steel / stainless steel crush tubes too!.

If I remeber right, I payed about 140 sterline with delivery, for a full set for my Avon. Try to contact Matthew at Powerflex. I had an exellent
service!

Just go to one of the kit companies!
I got mine from MK a few years ago.
I bought steel inners, the bushes and steel outers to weld to wishbones all as a matching set. Means no worries about fitment/compatibility of
sizes.
HTH,
James

Whatever you do, don't buy acetal - that's a hard, brittle, crystalline plastic, widely used in injection moulding to make SOLID things.
It cracks and splinters and is not the material to use for bushes!
Some acrylic formulations may be useful (poss typo?).
I'd use nylatron or something similar.

Yes to Nylatron, but only on the fronts and the panhard rod (if a live axle). I have a bar of the stuff if you want enough for a couple of bushes. You
need something more compliant (PU or Rubber) for the trailing links as they need to twist to a small degree.
And Marcus is spot-on regarding Acetal, it shatters quite spectacularly.

Au contraire! Although I wouldn't use it on a locost, acetal is a very good bearing material. We have used it on several rally cars in the past
which were absolutely pummelled on forest stages and they were fine. In fact we bent wishbones easier than cracking the acetal!
It's certainly not the best material to use but it is cheap and wears well (i.e. slowly! )
Other options are harder shore polyurethanes that can be machined, or make a steel die and cast your own polybushes.

Trying to cast bushes sound like fun! do you have any info on sourcing the raw 'poly' and things like release agents etc.
Is the 'poly' just plain polyeurethane? Or is it something else?

no experience but I know somebody that has, will try and find his number.
No idea on release agents either, but I doubt you need them as long as the die is polished well enough.
poly is poyurethane, but there are different compounds of it with different hardnesses.

Hi the bushes that the manufacturers suply are the same ones as the 30p ones. For an independent car IE 64 bush halfes @ 30p = £19.20 .Just then got
to make the inner crush tubes preferably from stainless.

EEk!!!
I'm surprised at that, although I could see it working if machined from solid. Would give a completely solid setup - similar in feel to
rosejoints - ie zero compliance!

Matt @ Procomp has been noble (and conformed with forum rules I guess) and failed to mention that they supply some bushes that from what I've
read/heard are a significant improvement on a locost.
If I wasn't buying what I am (i.e. a car with rod-ends) I'd be talking to Procomp.

Ah yes but the bushes we use will not fit any of the wishbones or brackets used by the other manufacturers and also have to go into a purpose made
housing.

Oh yes, certainly not compliant, but free turning with no stiction!!

My nephew works with plastics, he makes false teeth. I don't think the bushes would look good in gummy pink or various shades of white though. A
friend had some delrin which was pre-lubricated which I think he was turning to make swing arm bushes for his bike.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I am using UHMW for mine. I am turning this down on my lathe. We have been using this for several years for road racing and have not had any
problems. If you don' want to purchase UHMW. Cutting boards from the local butcher shop or a processing plant is made of the same material.
The problem is it might not be thick enough for the application. If it wears out, it is cheap enough to turn down new ones!

If you want the very best, go to SuperPro, somewhere in Somerset??
Good Aus product and the very best money can buy. A full set with SS bushes is about £70.
They supply replacements for the Triumph Herald/Spitfire bushes as mentioned in 'The Book'.
And then there's the Good ol' QH Y419's......
Cheers,
Syd.

Sorry for popping this back to the top but...
I'd like to make my own bushes not for cost but for the challenge. Therefore can someone suggest a supplier for buying rods suitable for the
task?
I've googled "Nylatron" (as it was mentioned earlier in this thread) but there seems to be a few variants and I'd like to try
to source something fit for purpose.
Wisbech Engineering supply 60 shore urethane bushes so I'm guessing this is the hardness I should be looking for?
Which Nylatron would be the equivalant? Is Nylatron even the same material as the urethane (polyurethane?) that others supply?
