Sorry for the late reply guys, I’ve been working out of town on a business trip the past few days and haven’t had a chance to respond.
I assume some (like myself) didn't mention the rod before since you're creative enough to do just about anything with it, but as soon as it got mentioned here in this context I knew where you were going. I've never done it from start to finish myself but am familiar with the concept, and it sure beats the hell out of rolling the lips with a bat or just cutting them off and saying "Done". What you've done is smooth, sturdy, and easy to make "purrty". It can also act as a gutter to a slight degree by redirecting dirty water away from constantly dripping straight down onto your wheels, which would occur if the lips were merely removed. It's a cool trick that I've seen butchered more often than not but I'd expect nothing less than stellar from a man of your skill level. A lack of attention to detail is what kills this mod but you've got more of that than most.
Thanks for the compliment, I guess I’ve set the bar pretty high for myself. I’ll try not to disappoint.
I can’t take credit for this little mod, it’s something I recall seeing in an old Street Rodder magazine many years ago. It must’ve made a pretty big impression on me, as I’ve stored it away in the back of my mind all these years.
Rollling the edges or cutting them back wouldn’t have been the right choice, a rolled or hemmed edge is just a dirt and water trap waiting to happen. Can you say rust? And a cut edge isn’t friendly to tires, I can attest to this from my younger and more foolish days.
Plan to weld the 'inside' edge as well?
Negative. It’s completely unnecessary, would create more likelihood of warping and isn’t worth the effort. That’s why I said this:
I’ll treat the rust pits, then likely epoxy prime the backside before finally seam sealing the remaining inside edge of the round stock
Boy, a TIG welder sure would be nice about now- well-yesterday.
Fact. But I make do with what I have. This has been brought up and mentioned a couple times in the past, and it’s true. However I’ve established a system that works nearly as well, at least as far as managing the heat is concerned. The softer welds and more versatility would definitely be more advantageous though.
I’m at a point in my life where buying a TiG welder is very feasible, but now I have indecision paralysis. Do I buy a welder and then take the courses to learn how to properly use it, or do I take the courses first, then buy a welder based on what I’ve learned in the courses?
Real chicken or the egg conundrum.
With my luck, I’d fork out the big bucks for one, use it a couple times, finish the car, and then never need it again.
Lol
Ok. Now that I’m back from my trip, I got a couple good hours in The Skunkworks tonight and got the welds dressed down and hand filed.
It’s difficult to get decent pictures of it, but it turned out really well. The key to this is conservative use of the grinder to only take the tops off the welds, and then liberal use of the hand file to finish it off. 80 grit on the DA as a final step made it look like it was supposed to be that way:
Here’s what remains of the rust pitting after trimming off the majority of the lip flange:
Not terrible, but it needs to be addressed nonetheless. Enter the Rust Mort rust converter I picked up last weekend:
I like to apply this stuff with an old toothbrush, it allows me to work the product into the pits better than a regular paintbrush. This stuff needs to be handled with a certain amount of respect however, as it is essentially phosphoric acid. Disposable latex gloves and eye protection are a minimum requirement here.
You may notice that there isn’t much of a reaction here, that’s because the majority of the rust was sanded, fibre wheeled, and ground out beforehand. All that was left was literally just the deepest remaining pits. A successful reaction is when the pits turn black, signifying that the conversion is complete.
It’s difficult to see in this picture, but there are a couple really small pits in the very top right hand corner that I wanted to nip in the bud.
Once this stuff has dried, I need to neutralize it with a water rinse, and give it one more quick going over with the DA.
The next step for this flare on the bench is to smooth out some of the deeper grinder marks on the backside with some fibreglass filler and putty, then epoxy prime the backside. Once the epoxy step is done, I will seam seal the remaining round stock edge and at that point the flare will be ready to weld into the fender.
However, I’m not going to start breaking out all those related materials until the flare for the other side is done to the same point. So next I’ll repeat these same welding, grinding and filing steps on the driver’s side flare.
Looks like I know what I’ll be doing tomorrow!
