I figured this was the most appropriate forum to ask this. Has anyone dealt with getting parts type III anodized? I would be getting my two BBU aluminum hubs hard anodized, I am looking for a place that will do small batches since it is only two parts.
Anyone have any recommendations? Do you have any info to impart and/or specifications? I know the part grows slightly from the anodize, but I am not sure if I need to specify depth of coating or anything like that. Scott at BBU said any growth shouldn't pose an issue with the races fitting back in or the studs being pressed in afterwards.
This is a situation where I don't know what I don't know.
Any pertinent input is appreciated

 

I've had many parts hard anodized clear. It gives a nice dark grey finish. I've never had the anodizing cause a problem with the fitment of any part after anodizing. I think the thickness is something like .001" and I wouldn't think twice about anodizing a hub. Go for it!

The thickness is negligible and often in the tenths. Any shop should be able to toss your parts in with any other batch they are running at that time. I would call around and see who is willing to throw a part onto another job. Just be clear to them on the material you have. I am pretty sure the hubs are 6061 but you will want to check so you don't risk contaminating their tanks.

 

I actually contacted Tobin at Kore3 and he gave me a link to a website for services such as this, to place in NJ that do anodizing.

I might just buy what I need to do the process myself. Caswell plating sells a setup for this. I think I might try my hand at it. I can buy some 6061 and test the process before I put my parts in to see how it works out. I have more stuff I want to do now, plus if it works I can do Type 2 and do parts for other people to pay for my setup.

 

If you have a good high current low voltage power supply this is not something that is challenging to do. You need some battery acid, some lye a decent bit of distilled water and some electrodes. I never got the dye to take well (didn't read the instructions on the rit I used) but I got some Caswell dye and I'm going to give it another shot soon. It's not that it didn't anodize (a multimeter on the surface showed infinite resistance indicating aluminum oxide vs aluminum.) rather a dye issue.

 

Type III anodize does not accept dye very well. What you were doing is type II anodize.
