powdercoating frames..

Do it - the black frame looks cool.

when I was dropping off the ZX6 frame, the guy looked at me, tilted his head in a slight sarcastic sort of way, and said 'black coat then..?'. Apparently every other frame that comes in is being done in black.. I didn't do the ZX6 frame black, cos it wouldn't have suited the rest of the bike (green and white, with some pink/purple I think), just would have looked odd. So it got a shade of silver (one of 34 shades)

whats wrong with paint??? my painter duz heaps of bikes, and the joy of paint is if its a external surface scratch then it can be easily fixed

And at what point are you effectively altering the heat treatment of your frame? Depending on what it is made from.
Some allys work harden, some (I imagine jap frames) require a heat treatment process.

Theoretically if you get it hot enough then you need to retreat it or it will be weaker. Maybe someone with a better grasp of metallurgy would correct of confirm this?

I dunno on that, but I know what you mean.

These guys are the biz when it comes to stuff like this, been doing it for years and a few of them ride themselves. Mainly they are industrial (I think, well, get that gist), so they know their stuff when it comes to metals and their properties

So you are saying the painters know their stuff when it comes to metallurgy?

Well they can tell you how high the temp gets. . .

not resistant to petrol wat the f**K

oh that sucks then can you get powdercoating done that is petrol resistant?

whats the difference in hpc coating anybody know?

ive got a place thats quoted me $120 to do my chopper frame

have to give him a ring and ask about the petrol side of things

I tell you guys what, if theres one thing Ive learnt from being in the trade, its that if a customer already has one thing usually he'll want the exact opposite to help him 'customise' his ride.It seems to be basic human nature. How many times have I made solo seats cause they dont want to take the mrs or a dual seat cause they do, a big tank cause the one hes got doesnt hold enough petrol, or a small tank cause the one hes got is too bulky, a half fairing cause it shows the motor better, a full fairing cause it works better or no fairing at all cause hes building yet another streetfighter,a short windscreen cause the one hes got buffets his head a taller windscreen cause the one hes got doesnt protect him enough. Its the same with finishing details, a round headlite cause its retro, projecter beams cause theyre in fashion this year,a silver frame cause his one is black, a black frame cause the current fashion is for silver. Ive seen it first hand time & time again.After a while, it all becomes almost predictable

Which is a good thing as it makes my job a lot easier in the long run

If you are getting any coating done bear in mind that unless you specify low-temp powder, you are looking at 200deg C for a minimum of 9 minutes, usually about 12 when you take the safety factor we all allow for to make sure there has been a full cure. Occasionally, usually in alum. you get the metal reverting to pre-formed shape. I haven't heard of it happening on something like a frame though.

you don't happen to do powdercoating for a job do you rasty ???

Aluminium Alloys come in Seven different compositions, some are heat treatable, some are not. The temperature needed for Precipitation hardening is in the region of 500-570 degree Celsius. As the frame is heated to approximately 100 degrees material properties stay largely unchanged.

But I've only done this, cos it's a new frame that was completely stripped and it's being rebuilt from the frame out. Else I don't know if I would have bothered. But, I just did a photoshop job on the 636, and I must say, it's a bit tempting..

Is it really worth stripping a bike completely to pieces just to coat the frame?

oh, I'll post photos of the frame as soon as I get home too, for those curious amongst us

Although I liked the before pic first. However, your bike, your choice. Nice bike either way buggy.

Am i the only person who notised that it is the same photo? just different coloured frame?

**bugjuice** · 9th December 2005, 19:49

i noticed that you can't spell..

ü bein serious?

So not good for Jappers at BEARS MC clubs then
