Coupe Rear Tie Rod bushes

Would you like any cash up front? I know tooling/prototyping is a bit expensive. I remember the first set of samco's which required a fair bit to cover tooling.

I'm planning to make some nylon bushes up myself when i can get access to a lathe to test the design etc then see how it works before committing to manufacturing.... i'm not making anything out of this so its a big risk putting my own cash into a new unproven product, or expecting people to pay upfront for something unproven also

we got any sort of time frame for this one yet mate??

nope! it'll cost £600 to get a batch of 20 sets made so i'm not in any rush to stump it up lol
as i said above, want to make sure the idea works for a start

[anton]

if it helps at all i would be happy to pay for mine up front with some extra for your R&D if you like, i know £600 is a big blow to one persons bank lol

Right, i've knocked together a basic roughly scale drawing of the rod and and possible bush design on MS Publisher
comments / ideas / abuse welcome

hopefully this is enough for these mfrs to let me know a pallpark cost and possible order numbers etc


I'm going abroad for 2 week tomorrow so will hopefully pick this up on my return and move things forward.

cheers
Alex


EDIT: Can anyone confirm if this bush would potenmtially work for the Type85 or URQ?

any updates on these bushes?

Kev (Bambridge) is working on a prototype as we speak

Will be posting them back to you today, done 3 variations for you to have a look at Alex?

[Error404]

cool - sounds good Kev, i'll look out for them

I need to remember to send you that front tie rod to look at

[Holla]

any idea when they are going to be finished and what the final price will be? would be nice to change these bushes as well, when I'm changing the rest

My apologies, these have taken me far to long to get done!

Alex(error404) will hopefully be testing them soon, and i wil let him know the cost of a set.

Best Regards

Finally got a chance to get in the garage after smashing my ankle up and being a bit immobile

Kev had sent me a couple set of Acetal / Delrin bushes to test following the design a couple of pages back, and including some grooves in the bore of the tophats to reduce the contact area and to retain lubricant. I've test fitted them today. The fitment into the rod end is very good, and an easy install. Kev has used acetal I think becasue of the cost of casting polyurethane and difficulty machining it (is that right Kev?). These Acetal bushes appear very similar in hardness to the black Powerfex used in their wishbone bushes, which is 95 shore A IIRC

I did a back to back compared against stock rubber bushes - I can say that these Acetal bushes will be a BIG improvement. Fitted up to the subframe, I could get about 35mm of flex out of the stock bush measured at the end of the tie rod and being forced forwards and backwards by hand. With the acetal bushes fitted this was reduced to about 5mm of flex

I won't have a chance to road test these for a few weeks yet unfortunately, but at this stage as i have said to Kev, I don't think there is any further work needed and they appear to be perfect for purpose.

Thanks Kev

Alex seems very happy with the bushes, so i have worked out a price for the group buy. If theres still interest for 20plus sets i could supply them @ £25-00 a set + postage.
