Anyone need some powder coating done?

I don't know exactly whay happened...I guess the rock chips negatively impacted the fatigue life of the frame due to the increase in surface roughness near the structural welds.  Parts of the trellis frame just fell off completely near the head tube.  I almost crashed but it didn't happen until I went over the little curb pulling into my driveway.

Again...   and ...

The problem is that you didn't have any speed holes drilled into your frame ahead of time. That would have increased not only the structural integrity in the frame, but also would have helped you go faster. I've also read accounts where rocks end up not hitting the sensitive welds, but instead, they actually go through the speed holes thus avoiding any problems!

Speed holes?

Hmmm ... you know ... I did get hit in the helmet with a small rock on the I-17 on the way back last Saturday.

Maybe some speed holes in my helmet would help ... but then isn't my skull at risk? Maybe some speed holes there too then?

I thought you already had speed holes in your head?

racers use nitrogen. helium would be lighter. maybe fiber locknuts instead of steel? i got it...
start your bike at home and leave the battery there!  D hee hee G.

Now this is the kind of thread that makes sense.
My hands are burning from rust prevention acid trying to clean out the rust (on the vfr fuel tank) when now I hear that I should just let the rust work its way through and their you have it, A lightened bike....natures speed holes

Muffler bearings... what about the muffler bearings?

...and cross-drilled brake hoses?

My father was one of the first pioneers to bring powder coating to the US.  The EPA regulations were written off of his shop and his process control.  It was originally developed by Nazi Germany during WWII as a steel tank coating process.  Some of the first gun/transformer systems were the size of a VW bus.  Now they are down to an 8oz handgun (use certain polymer plumbing to generate the required KV of static electricity). 

I will say this from looking at most powdercoat work... no shop in this valley does it correctly.  When done correctly it is the strongest coating you can have.  If not done properly it is one of the worst.  If you do not have proper adhesion you can have pockets form under the surface, which will draw moisture and cause corrosion.  Also, they do not properly cure the material.  To do so the surface temperature has to reach a certain point, which is specific for the powder you are using.  I can go on about this all day but bottom line is... just use a rattle can of rustoleum.  You will get just as good adhesion and durability as powdercoat jobs in this valley; and save some money in the process.  Plus, if you happen to scratch the part (which proper powdercoat should not scratch off... one of our quality checks involced a coin scraping as hard as you could press against the surface with no marring) it is not a big deal... just respray it.

And yes, Ducati does not use powdercoat on any parts.  Nor does any of its suppliers (wheels, suspension, etc.).

Sorry man but I have to call BS. I am sure your father is a great guy and all, but I doubt he is a Nazi defector and introduced powdercoating to the US. Also, you shouldn't run around knocking all the powdercoat shops in a city of 4 million people just because your non-expert opinion thinks the few that you have seen don't "look" correct. I seriously doubt you can tell whether proper adhesion has taken place by a quick visual inspection.

Also, sandblasting sure enough adds surface roughness and surface roughness can effect fatigue strength. That said, the frames on our bikes are quite strong and really don't suffer that much from the load cycling they are subject to. I have known many motorcyclists that have tons of miles on various bikes and I have never heard of a frame cracking from fatigue. There were stories about first gen. Hyabusas that had this problem but that was due to faulty welds. In the end, these bikes will put up with more than you think.

How about powdered-sugar coating?  mmmmmmmmmmmmmmm

Ok... call BS all you want.  We DID test samples from several shops.  And I have tested several sets of race wheels that have had surface finish failure.  Do you have a paint MIL gauge?  Do you know the proper testing procedures?  Taken a coin to any items you have had coated?  Have you inspected the work from these shops?

How dare you insult me in a way of making reference to a Nazi defector.  I was making reference to the timeframe and the techonlogy base.  It is known in several arenas that the germans were ahead of us in technology during WWII.  I am not saying that he was THE guy to do so but when he started using powdercoat in this country there were only 2 colors available and they were from Switzerland.  He had a local chemical company in KC analyze and duplicate the material and helped with the development of other colors and the wrinkle texture process. 

You might want to ask more questions before running your mouth in that manner.

Powdered toast?  mmmmmmmm

...and what about that movie "Powder"?  Didn't that pale kid wear a coat?  and a hat?  ...and then there was all that lightning and stuff.

Why would I know some ASTM, ASME, etc. testing procedure for something that I don't work on. And having tested a few samples doesn't qualify you to be able to verbally bash every shop in town. And by the way, I said I doubt that he was a Nazi defector. Nothing to get your skivvies all in a tangle over. Additionally, I will continue to "run my mouth" in whatever manner I see fit.

I might have a couple small parts that I want to get coated black (probably matte or semi-gloss finish).  Usually the shop I use charges a minimum, so if you combine a batch of parts it can be really inexspensive.  Like under $10 for each of us if you have a couple small parts.

Post up...let's talk...  

The new 1100 will need A LOT of black powdercoating (amongst other changes).  I'll have to post up a similar thread when that day comes.  SOON!!  I know Tom Hull uses a guy for powdercoating.  Who are you using Deitrich?

The WHAT WHAT!?!  Sweet!  Have to see it soon.  What did you do with the 'ol 620?  

I use Arizona Powder Coat.  Because they're cheap.  I let the fear of adhesion, corrosion, and cracking frames fly in the wind.
