sr2 Posted December 5, 2015 Share Posted December 5, 2015 I'm trying to buy some urethane or nolathane stock so I can turn up my own mounts and bushes. Does anyone have any idea where I can buy some? 1 Quote Link to comment Share on other sites More sharing options...
bathcollector Posted December 5, 2015 Share Posted December 5, 2015 Autolign supply it in various sizes. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted December 5, 2015 Share Posted December 5, 2015 Sr2 if you haven't machined it before then maybe buy a small amount to play with before committing too much $$. I have found it to be a total bastard and would not bother again..although I didn't try for too long. Quote Link to comment Share on other sites More sharing options...
Mr Vapour Posted December 5, 2015 Share Posted December 5, 2015 Have you thought about buying it in liquid form and pouring your own.  Not uncommon thing. I have fou.d a supplier in onehunga but can't remember the name. 1 Quote Link to comment Share on other sites More sharing options...
AllTorque Posted December 5, 2015 Share Posted December 5, 2015 Someone told me once to freeze it before cutting it. 2 Quote Link to comment Share on other sites More sharing options...
Nominal Posted December 5, 2015 Share Posted December 5, 2015 Last time I had to resize some it was more effective to use a grinder on it. Quote Link to comment Share on other sites More sharing options...
yetchh Posted December 5, 2015 Share Posted December 5, 2015 ↑ this, much easier  than anything else I tried including a lathe.. Quote Link to comment Share on other sites More sharing options...
SOHC Posted December 5, 2015 Share Posted December 5, 2015 if you can get a mountshop catalog they have all the measurements and photos of mounts and bushes, its very handy. Quote Link to comment Share on other sites More sharing options...
thegreatestben Posted December 5, 2015 Share Posted December 5, 2015 Nolathane supply stock but finding someone who carries it seems tough. They do have a guide to machining it and as others have mentioned they recommend freezing it first. I wonder if immersing it in dry ice would be the next step?

kpr Posted December 5, 2015 Share Posted December 5, 2015 machines ok if you spin it fast and make right shape tool from tool steel.   2 Quote Link to comment Share on other sites More sharing options...
sheepers Posted December 5, 2015 Share Posted December 5, 2015 mulford plastics sell it. but without question is is way more expensive to buy it an machine it than it is to just buy nolothane products.  oh, and if you need something that isn't available racelign in mount wellington can take a cast of an old bush (or any mold really)  and make you a urethane replacement .  turning it is difficult and dangerous if you don't know what your doing. 2 Quote Link to comment Share on other sites More sharing options...
sr2 Posted December 5, 2015 Author Share Posted December 5, 2015 Thanks for all the info guys, think I'll source some urethane stock and have a little play. I still occasionally still use tool steel on my lathe (showing my age again!) and suspect a similar shaped tip to what I've used on nylon would be a good starting point. Will let you know the results.  Re: 11; I'm not anticipating it being a "difficult and dangerous" exercise. (If you want difficult and dangerous try cutting a twin start thread on a piece of 316 stainless!). Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted December 5, 2015 Share Posted December 5, 2015 Has anyone tried grinding the material? I reckon a grinder held in the toolpost with course grinding wheel may be interesting. Quote Link to comment Share on other sites More sharing options...
Ghostchips Posted December 5, 2015 Share Posted December 5, 2015 i have ground nolathane, made red dust and when it got hot i think it made red stringy stuff. It was a bush i got from the wreckers so it might not have been nolathane, pretty sure it was though.

nvmyvl Posted December 6, 2015 Share Posted December 6, 2015 I work for LEP Engineering Plastics. We were formally known as Mulford Plastics. If you want some, let me know and i will cut you a deal. And we can make bushes etc from moulds. Cheers Blair Quote Link to comment Share on other sites More sharing options...
Bangbug Posted December 6, 2015 Share Posted December 6, 2015 I have some. How much you need 1 Quote Link to comment Share on other sites More sharing options...
Steelies Posted December 6, 2015 Share Posted December 6, 2015 yeah be careful turning it, if your experience with turning nylon saw work pieces flying across the room then expect no less from the urethane Quote Link to comment Share on other sites More sharing options...
nvmyvl Posted December 6, 2015 Share Posted December 6, 2015 Only need a sharp piece of tool steel and a flat end drill to machine urethane. Ive been machining it most werks, for the last few years. Never had it fly out of the chuck either. 1 Quote Link to comment Share on other sites More sharing options...
Guypie Posted December 6, 2015 Share Posted December 6, 2015 I turned a bushing down to size once, used one of those yellow grater kinda things in the end as it just pushed out of the way of the tool. Quote Link to comment Share on other sites More sharing options...
