Topic: Powdercoating Hubs on CB400F

and more.

Hey Chris,
I think they look pretty good. Most of the un PC'ed area's will be hidden so you wont notice the funky mask job. You might notice the outside of the hub where the sprocket goes, but since the sprocket will be in place it will break up the continuity and take your eye away from it. I wouldn't worry about it.

As for the PC over spray in the threads I would say to run a tap through to clean up the threads, but really who has a tap that big?
Use a pick or a dental scale tool (My hygienist saves all the used ones in her office for me, they work great!) and just do the best you can to clean up the threads. Doesn't look like there's a lot of over spray so it shouldn't be too difficult to do.

Some powdercoat is soluble in lacquer thinner. You could very carefully use the corner of a rag to wipe on some thinner and clean off the excess coating if it's necessary.

That's a sloppy, lazy job. Getting that powder out of those threads is going to be a pain, and it needs to come out of those dampers too or the sprocket carrier is going to wedge in there super hard, if you can even get it in.

Rear wheel spacer bears on that brake panel, good luck getting that flat and it's going to wear and scuff when you torque the axle.

F-

I agree NobleHops. This was my first powdercoating experience and I'm not too happy with a few things. The over-spray on the threads is real annoying. I'm gonna take them to a shop and have the threads re-tapped and just have them install the bearings while I'm there. Hopefully they have a tap that large.

So after the bearings are installed I'm sending the hubs out to Buchanan's Spoke to have the Sun Aluminum Black Anodized Rims (both rims 2.15x18) along with stainless steel spokes that will be laced and trued by Buchanan's Spoke.

Just curious why you want the wider rim on the front?
The bike will handle better with the 1.85 (WM2) rim and thinner tire on the front.
Not knocking your choice, it might be the look you are after, just curious.

I have the anodized black Sun rims laced up with Buchanan spokes and love them. My hubs are also powder coated black. Your set up will almost be identical to mine except I went with the WM2 /WM3 rim size.

Kevin,

Don't be too hard on yourself PC is not as easy as it looks.  If you got over spray inside the brake hub that really sucks as it will take forever and a year to sand off.  The key I found to a perfect finish is to have the surface be super smooth to begin with.

For example I thought PC signals would be easy, but the old crappy chrome behaves in a very unpredictable way.  Don't give up on PC, just be sure to do a better job of taping.

Hey Kevin!

Yeah, I contemplated the rim size for a while but finally decided on the larger front tire/rim because I'm not a big-time, knee scraping in the turns kinda guy. I live in downtown Columbus, Ohio and really just ride my bikes to cruise around. I'm favoring form over function. : )

[cgarbe]

So took the hubs to the shop and the tears went on without a problem...except they had to take the bearing spacer off the bearing.

The front hub however was a problem. Couldn't get the retainer onto the hub so it was recommended I have it machined to remove the PC as well as the boogered thread.

Sigh

Question: Has anyone powder coated the rim, hub and spokes all together?

[cgarbe]

I feel like that would lead to a lot of cracking of the powder coating around the spokes.

People have done it with decent results, but rim can not be trued afterwards.  It is a "one time thing"
