Title: another powder coating question
Post by sbaugz on 02/04/11 at 04:18:44

So, I am getting ready to send some parts to have them powder coated. I have a question about the clutch cover. How should I have the powder coaters handle the part of the clutch cover underneath the oil filter cover? Does that whole area underneath the oil filter cover need to be masked off, or should I have them powder coat right up to the part where just the oil filter drops in? Seems like it might be difficult to mask off the exact area around where the oil filter cover bolts on.

OK, you have the surfaces you see when everything is assembled, right? And then there are the surfaces you don't see when everything is assembled. I'd have him mask things so that the color wraps about an eighth inch or so into the areas you don't see. You want to accomplish two things. The first is to keep the coating off the circular mating surface where the O ring creates a seal. The other is to not end the coating right at the edges/corners -- except on the edges where the cover mates to the crankcase, of course.

Oh, and keep the coating out of the oil filter cavity, of course.

The guys I have do my stuff know how to do bike parts. Always do only what you can see when fully assembled like was said before. All machined surfaces will be masked off, other wise you won't get your seal.

Rereading what I posted above, I saw that it might not have been clear that the 1/8" thing was just about the area of the clutch cover under the oil filter cover.

So I got a bunch of quotes on powder coating the clutch cover, oil filter cover, generator cover, and front fender. Prices include stripping the parts, prepping and masking them, and coating in black. Prices range from $110 to over $200.
I wonder why the large range in prices? Seems like I should just go with cheapest? I can't imagine there is that much variation in quality of work between professional powder coating companies?

That is WAY too high holy crap. I got a TON of stuff done and it wasn't that much. Two spoked rims were only 100 and those are a HUGE PITA to blast and stuff. My side covers and uppers and a bunch of other stuff was like 50.

I've used two different local guys. One is really inexpensive and has a huge color selection. Black? Which of a couple dozen blacks do you want? But he's about 25 miles away with a lot of traffic. I've also needed him to redo a couple of pieces.

The other guy is three miles away but his prices are about two to three times more. He doesn't have the color selection, and his hours are weird, but he does excellent work. Never had a problem.

The first guy makes most of his money from industrial and architectural work -- huge pieces where little flaws can go unnoticed. Motorcycle sized pieces are a different matter. You notice small things. The expensive guy makes most of his money coating car, truck, motorcycle and boat parts. Customers in those markets are used to paying more. Both charge what the market will bear. They just serve different markets.

Hmm, not sure how you got such a good deal, but $50 seems kinda low to me based on the 6 quotes I got. Seems like it would be way more work than $50 to sandblast, prep, plug holes, mask off and powder coat 4 covers and a front fender. I was thinking the $110 quote sounded pretty decent.

They only charge 50 per rim for any rim, unless you want to get really fancy and start adding layers. I live in Nebraska though, stuff is much cheaper in this area. Plus I send them a lot of business from my friends and let a lot of other shops know about using them. They do everything from car frames to bike parts and really anything you'd ever want to coat.
