CZCAR Posted November 20, 2003 Share Posted November 20, 2003 ok heres the deal i have a hole workshop full of goodies sitting on the property, my pas engineering business, one brainwave i have last night is this, on the lathe i sumtimes use polyurethane chunks, big round cylinders of it to create wheels and bushings, if i got the right compound would it be worth making my own bushings , for say suspension and sway bars, etc? or since the suspension plays a major part, is it not worth the risk? id really like to try it, since im in NZ parts and shipping are very pricey(in my opinion) if you think itd be to dangerous , please let me no, and why thanks Cameron Quote Link to comment Share on other sites More sharing options...
BillZ260 Posted November 20, 2003 Share Posted November 20, 2003 I would imagine that if you could match the compound and you had dim'ed dwg's you could make your own. Not sure where to obtain the compoud they use though. You know anyone with a set you could compare too? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 20, 2003 Share Posted November 20, 2003 My old boss had a side business making Delrin bushings for 944 swaybars, because the power steering leaks right onto the rubber bushings and destroys them, especially passenger side. He and a machinist made an aluminum mold and injected the Delrin. It was a low pressure deal, not a high pressure mold. The problem they had was determining the correct hardness of Delrin to use. I would think that you would have the same issue. They figured it out through trial and error on the boss's car. You might have to do the same.

CZCAR Posted November 21, 2003 Author Share Posted November 21, 2003 cool thanks, yeah i think ill just go trial and error , obviously do a little bit of measuring, unless of course anyone has for some peculair reason the measurements for 280zx bushings, umm so if i get the right compound noone thinks ill have to much trouble, with breakage, since im doin it on the lathe.

Pop N Wood Posted November 21, 2003 Share Posted November 21, 2003 You can get raw material at McMaster Carr. They even list tensile strength and things like that http://www.mcmaster.com/ Quite a few people have machined bushings because sometimes the ones you get with the kits don't quite fit. If you search through the old archives, there are a couple of places that sell complete kits for Z's significantly cheaper than MSA or VB. Might be more cost effective since you will have to pay shipping to NZ for the McMaster-Carr stuff anyway. Quote Link to comment Share on other sites More sharing options...
