JMortensen Posted September 18, 2004 Share Posted September 18, 2004 I bought a couple of 280 hubs from Juan @ JSK when I bought his brake kit. Just got into them and after cleaning off the grease I can only say holy crap are they rusty. I realize that I can get a couple more hubs cheap if need be, but I've already got these here, hence the idea. Is it possible to turn the wheel mounting flange on a hub like a rotor? I'm trying to think back to my wrenching days and I'm thinking that a standard brake lathe might not do it. I started to just sand the surface and there are some pretty big pits. I'm sure once the rust was gone it would probably only take .010 or so to get them perfectly clean and straight again. So what do you all think? Dumb idea? Not worth it?

Zhadman Posted September 19, 2004 Share Posted September 19, 2004 Might be kinda tough to put in the jaws. Maybe there's a machinist on here who could pipe in. I'm sure it could be done. There are centerbores on both ends of the stub axle for fixturing. It's not like you're gonna be cutting a bearing land (correct terminology?) and have to keep a close eye on TIR.

aziza z Posted October 7, 2008 Share Posted October 7, 2008 Yea I know this thread is old but did you end up machining them? Im in the same spot right now and also want to check the hubs for straightness. If you did how much should they be machined? .010? Quote Link to comment Share on other sites More sharing options...
aziza z Posted October 7, 2008 Share Posted October 7, 2008 Found the answer. Heres the thread. http://forums.hybridz.org/showthread.php?t=109578&highlight=lathe+hub Quote Link to comment Share on other sites More sharing options...
LLave Posted October 8, 2008 Share Posted October 8, 2008 How about just media blasting it. Or maybe a bath in muriatic acid? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted October 8, 2008 Author Share Posted October 8, 2008 On my hubs they looked like they had sat in a junkyard for years. They were really heavily pitted. I just ended up buying new ones from zbarn.com. I still have the junky ones, but cleaning them isn't going to cut it. They'd probably need .020" taken off to make them flat again.

aziza z Posted October 8, 2008 Share Posted October 8, 2008 Im not really worried about the rust to much. Im just doing it to check straightness of the hub. Planning on getting it nickel plated after machining. That should get rid of the rust during the process. Quote Link to comment Share on other sites More sharing options...
LLave Posted October 9, 2008 Share Posted October 9, 2008 Ahh I see. It is not so much a rust issue but an issue of the flat surface being true. I don't see anything wrong with truing them up on a lathe. But then again I am not an engineer and I draw pictures for a living. Quote Link to comment Share on other sites More sharing options...
