Powder coating the frame

#1

Post by ianstaley »

I have a problem with the used frame I bought for my GL. My bike was originally a Dutch registered bike, I brought her back to the UK and in the process of rebuilding her. So I bought a good used frame with UK registration to make it easier to use in England. Now about 7 months ago I had her blasted so I could do some welding around the centre stand as we all know this is a major weak spot. So suitable cleaned and welded. I let it outside and yup she is rusty again. But I noticed before then that there was some pitting in the steel, so I need to get shot of that. So before I go get her re blasted I wan't some options on getting rid of the pits, other than brazing. I think to braze it would take a week and then another to sand it down.

Please bear in mind that I have two options, powder (preference) or paint. Any suggestions, I even thought about trying to lead swipe solder it but I am thinking that's a bit beyond my capabilities, even so they all had to start somewhere, maybe the same with me.

There are some sandable fillers that are designed to be used under PC. Two I can think of are called Thermobond 3 and Tiger Drylac EPO. One commercial PC shop here has used the Thermobond product with good results. Basically they are high temp body fillers with some conductive particles so the powder sticks during the spray process. I'm not sure how much work it would be on your frame, but it is an idea you can look into.

Thanks, I have heard of the Drylac, but it is quite involved how you apply it then heat treat it by all accounts, the other I haven't heard of, so will check that out. So again thanks.

Depending on your standards and the depth of the pitting, powder coating hides a multitude of sins.

Good point. The "crash bars" on my sidecar were seriously pitted and after a trip to the powder coat shop the pits are barely perceptible under the PC layers ("chrome" and clear coat).

Ian,
Powder can be laid down in a thicker layer than paint, so it can fill at least minor imperfections/pits. The issue I have with PC vs paint is, when (NOT if) you get rock chips in it, paint can simply be sprayed over and look good while PC is much more difficult. Sure, you can spritz some black paint over any chips in the PC, but it won't blend well. Granted, PC is pretty tough stuff and more resistant to chipping than paint, but I really believe that chips and scratches are inevitable. Unless you don't mind having war wounds, you need to consider how to maintain the finish...

Update yesterday I went to a company near where I live they are Blasters and Powder coaters. Just went to ask has he some examples of his work, so he showed me some wheels standard daily bread for these guy's, but they advertise as Bike frame specialists, he took me to the finished room where stuff is held to be collected. There was a Honda 750x4 frame that he had done in metallic red, it was only one word "perfect" he said it was even rustier than mine was when it came in. There were some marks but as he said sometimes it just isn't feasible to get out all the marks.

My frame was rusty but his statement little pitting, so he is going to first blast it he said he will use soda first, and if there is some left go to a slightly harder material, we will discuss it after the first blast, if it's okay he will re blast it and direct to powder, he will use a very fine and thin layer of primer, then the right colour on top, cost about £100 - £150.

I think that's fair.

Ian

PS I will post pictures of the result.

Are you going metalic or basic black???? My local P/Coaterer can do matt, semigloss and higloss in black and other "straight" colors.. Be sure the you can see an example of what you want, eg gloss black... In reality the P/C its not as "glossy" as clearcoated black 2pak paint but it has its own enduring advantages..

Actually I went back today as I forgot the centre stand, not sure if I will use it yet , but I also tool the fake tank insert that has been powder coated already, but I am going to get another as mine had some rust which has eaten into the plate work. The from and all the metal will be done in ivory. see the pic below for the colour. And the update is £90.00 for the whole job?????
I have added two pics, one is the ineer frame of the fake tank, and the other is one of the new clocks I will be using.

That is much cheaper than I get charged for PC work in Calagary. I would say less than half the cost I would pay, maybe even a third :-? . The shop I mainly use does very good work, so I keep going back to them. However, they have a new owner and I have not tried them since?? I do most of the small parts myself, I have a dual voltage EW gun and a mid sized toaster oven, works well for the stuff that fits in the oven. I like your colour choice, the bikes done at NGW with white, or cream, frames always look very good IMHO.

I was inspired by the CONDOR bike, I just love that bike, I don't want to make a copy but it just says it all to me. My choices of colour for the tank sides and battery cover and the other side will be done in Black Cherry or Cherry Black whichever you prefer. It will have a slight candy pearl to it too. and about 8 coats of clear top coat and I will do it myself. The engine, will up to now will be polished; but I am leaning towards a Cheery Black crank case with chromed covers. Cylinder head covers, clutch cover and so on.

It will have a single carb conversion, I have the carb and a VW manifold, I have had a special spacer made for it as the mounting holes do not coincide with each other. So today I have been inspired to do a bit more on the bike, the rear mudguard and the old rear rack have been taken off. I was hoping to recover the rear mudguard, but it is too far gone. I am having a problem getting the top of the shocks off, the nuts are off but they seem to be fused, I guess that's what happens when left to stand for 15 years. I don't deserve my bike but she will be great again. I will make some more pictures and post them.

all there is to see is my wreck on the bike lift, slowly taking more and more off. I am happy to post pics of the rust but I think we have all seen the rust before, UK rust is much the same as USA rust, brown in colour.... So feast your eyes on European Rust. isn't it sexy.... lolol
