The delta frames would work great for powder coating too. Everything is metal so you could clip a ground to it.

The delta frames would work great for powder coating! Everything is metal so you could clip a ground to it.

Question is how would you load it into an oven?

The racks Dad has have casters on them, so it's easy to roll in and out of the booth and oven. He's been using them for well over 10 years now, and they do the job just fine for him.

That said, I'm always down to try something new, especially when I don't have a set way to do it in the first place! I'm eager to expirement with paint and painting techniques!

 

[The Renaissance Man]

I searched and found where I had first thought of the paint frames 5 years ago. If you are interested in making some, there is some info in post #184 HERE.

I had a bit of a setback with the primer.

The backside of the chainguard was the only surface that I didn't media blast. It was nice smooth metal and I didn't think it needed anything. Apparently, I didn't clean it thoroughly enough to remove the WD40 that I put on it a couple of weeks ago and some of the paint didn't bond.


So I made another trip back to the blasting cabinet. Oh well, lesson learned!

Seems like there’s always something but it must be extra nerve racking with it being somebody else’s bike.

Just like the underside of fenders, it's easy to not pay enough attention to the back side of chainguards.

I really don't think about it being for someone else. I work on customer bikes just like I would for myself (i.e. too many hours lol). The only difference is when I have to discuss things that I would otherwise decide on my own.

I did clean it with a degreaser but I guess I underestimated the power of WD40.

 

[The Renaissance Man]

Back in Black. (primer)

It took much longer to clean the gun than to repaint it. lol I'm ready for some sanding this weekend!

 

[kingfish254]

 

[The Renaissance Man]

WD-40 is the gift that keeps on giving.

While sanding the rack a couple of spots flaked off. I stopped and used compressed air to confirm that more areas were also popping loose. This time it was on the top and bottom sides. I just stopped and will take everything back down to bare metal again as soon as I can make the trip back to the blasting cabinet.



The good news is that the frame and fork are fine since they were not in on the WD-40 party.

 

[kingfish254]

Sorry to see that. Hate it when paint and prep don't play well together and bad surprises like this happen.

 

[The Renaissance Man]

I really should have known better.

I've used WD-40 other times in the past after OA baths to prevent flash rust, so I just did it out of habit. I wasn't thinking about the fact that those times I intended on keeping the original finish. This time was completely different because I knew that I would be painting soon. And of course, applying a layer of oil on raw metal prior to painting is not very smart even if I thought that I could clean it back off later.

Considering that I'm always very careful not to even touch raw metal with my bare hands for fear of leaving oil from my skin, it borders on insanity to willingly spray WD-40 from end to end! Total brain fart, but one that I won't soon forget!

What you may wish to consider is an issue I used to see when doing corrosion mitigation on Florida bridges. Contractors would sometimes collect and reuse their blasting media to save $$. However when blasting off the deeply penetrated chlorides from the surface, the salt contaminated media would be redeposited to the blasting hopper and resprayed onto the surface they were trying to clean, thereby recontaminating the part: the same with oils, etc. I am not saying that is your case because there are many factors that influence this, its just something to consider.....

 

[The Renaissance Man]

Salt contamination is not really a concern in our area. However, your point is still valid. I have seen traces of grease get into the media and cause problems.

I try to clean parts as much as possible before introducing them to the blasting cabinet. I actually cleaned the WD off of these parts with a degreaser but apparently, I failed to do a thorough enough job. The frame and fork were never contaminated with WD and they are both showing no signs of bad adhesion so I'm certain what caused the issues.

It can be fixed, but it's frustrating to get knocked back by a self-inflicted wound. Ultimately it is a first-world problem so it's not a big deal.

 

[The Renaissance Man]

Back in black blank.

I stopped by the Cobra fiberglass shop to drop off my molds for more convertible tanks and used their blasting cabinet there. I hope to shoot more primer on it tomorrow afternoon.

 

[The Renaissance Man]

Try, try again.

 

[kingfish254]

That guard has such cool lines to it. Reminds me a little of the Columbia ones they repopped years ago, but evern cooler.

 

[The Renaissance Man]

Back on tRack!

Got the rack sanded yesterday afternoon without any paint adhesion issues this time.

 

[The Renaissance Man]

Looks like a great day for painting outside today!

 

[The Renaissance Man]

I have all the parts sanded, cleaned, and strung up in the Delta Frames ready for paint.

After everything was ready to go, I went outside to set up the cones in a shaded area but quickly decided that it was still way too hot to paint. I've got my eye on Saturday for the next chance.
