Welp, after practicing I had pretty high hopes that this post would simply read "Second verse, same as the first!" and POOF! there'd be a picture of the second repair. All done and primered up.
But if I did that, you'd miss all this:
I mean looking at that picture now, it all looks so pleasant! Sure there are a few grinder marks... sure you can see a rather porous weld... but that's not too bad, is it? How DID that little bit of imperfection end with the fit of rage that lead me to repeated fender punches and the photo posted above?
Well, I'm glad you asked.
So we start our day much where we left off. The machine was set up and I was running low enough on gas that I said I'd kill the bottle by practicing my welds until I felt confident enough to go back at the panel:
And practice I did!
Except I wasn't really supposed to be in the garage today....
See, I don't know what it is about this week but man have I been in a bad mood. Maybe it's lack of project time or something, but either way I went to bed just absolutely fuming about absolutely nothing to the point I had a pretty good headache going by the time I put my book down and went to sleep. I woke up this morning in not much better shape.
Today was supposed to be the warmest day this week. We were supposed to have weather near 12-degrees (C, no idea what that is F), but when I woke up it was cold to the BONE! So after I dropped the kids of at school I decided that instead of heading to the house to prune back my last two pear trees, a mental health day was in order and I would spend the morning napping until I couldn't nap anymore (about 1-hour... it was a lame nap and the dogs woke me up...). Irritated at my lack of ability to nap, I figured a bit of project time would do me good. Out to the garage I went, and before long I was laying beads on the practice piece.
Things didn't start so well..
That's front side, followed by back side
I mean it's just two tacks so far, and I've seen fewer pores in pumice stone! I've seen shallower caves!!!!
I play with the settings (up the gas, really) and try again:
And try again
and play with the settings
and try again
and play with the settings
and try again...
Finally, I get a decent weld down (look back at the last picture. Kinda in the middle, it's the lowest one).
What I ended up deciding was that I needed better shielding gas coverage. SO what I did was clamp a piece of aluminum to the back of the panel and use that, not so much as a heat sink, but as a way to keep the gas near the backside of the panel while I welded on the top. It was working pretty well
Ok, so I got one good blob out of about 20 so I decide another practice pass is in order
Front side and back side (you're looking at the lowest weld when it comes to the front side. The other weld is old...)
Again, not perfect and I STILL cant seem to weld in a straight line, but no pores and not excessively blobby so I'm happy.
Back to the panel
These little magnets I bought aren't really doing a good job of holding what I need to be held:
So I ditch them in favor of clamps, and a I get to tacking things into place so I can do my passes. Welder settings haven't been touched and I figure I don't need to clamp in the aluminum piece just yet as I'll be going over everything with my final pass:
First four tacks went juuuuuuuust fine, but that fifth one there? That BIG BLOBBY one? Yeah. For some reason when my torch hit THAT SPOT the metal just DISSOLVED!!!!
I was able to get it filled back in by building up the edges with my filler rod, but that rage headache was starting to come back as a result...
"No big deal, move on" I tell myself.
I clamp the aluminum to the back side and change my bottle. This one is just about empty anyways:
So how did things go?
berkeleying terrible...
It goes like this:
1) start at the top left
2) Completely dissolve metal with torch...
3) turn amps down on the foot pedal
4) weld until you get too close to your clamp.
5) Let that side cool and work on the other side, where that big blob is...
6) hit blob with torch and get showered by sparks.
The whole time I'm doing this, I'm going back and forth between my fender and my practice piece... On the practice piece I can weld just fine, on the panel it just all goes to E36 M3!
The worst thing is, I somehow manage to burn through that big blob when I tried to pick the weld back up. NO IDEA how I did that, but POOF! Right through I went!
I almost didn't take that picture. You can see that I started with the grinder before it was taken, but you guys need to see my mistakes. Too often in this internet world do people pick up tools for the first time and instantly do amazing work. That's not me, and that's definitely not this build...
So here we are: I've ground things back, I'm touching things up, and AGAIN!!!!! Right there at that damn "big blob location" the welds just turn to E36 M3!
I've had it at this point. With the filler rod still in my gloved hand I start punching the fender repeatedly. E36 M3's falling off, my ground clamp drops to the ground, and I'm yelling loud enough that I'm sure my elderly neighbors can hear me...
So what happened?
Well, I tried all the usual things along the way. Grind things to bare metal, file of any shards/etc, clean with acetone...
It turned out that this switch was the culprit:
I must have bumped my machine somewhere during the course of the day (bottle change, maybe?) and my foot pedal switch got turned to "Panel control". This means that no matter what foot position I was in, I was giving the panel "full beans" and the machine was set at twice the amps that I wanted. It certainly explains the dissolving metal...
Now the right thing to do would have been to go back to my practice piece, and re-figure out what the crap I was doing but I had had enough of doing that for one day. I stubbornly soldiered on and quickly found out that I was going to have to re-learn (or un-learn?) what I was doing with this panel all over again (I don't think I can adequately convey how long it takes my brain to adjust. My whole reason for practicing is to get in a "groove" and then transfer that "groove" to the panel. With everything going cattywampus, my brain was all over the place and I was completely unprepared for how the weld would behave when I tipped in that pedal for the first time...)
anyhoo, when the smoke cleared and I stopped seeing red, things looked something like this:
Somewhere in there was one good section where I was actually happy with what I was doing and that reminded me:
I've been surfing once. It was in Aberdeen, WA back in 1999 or 2000. I was on a big foam rental surfboard and all my buddies had their own gear (they were good, too).
I spent the whole day falling down and watching everyone else make it look easy. I was relatively convinced I would never be able to figure out this surfing thing...
But somewhere in that cold miserable day, I actually stood up and caught a wave. I have no idea how long I rode it for, but there are very very few moments where I felt as good as I did just then.
So I just spent the whole day today falling flat on my face with this welder, and the damn machine definitely wasn't gentle about it. But somewhere in that last photo was at least 5-good seconds where I caught JUST the right groove and felt pretty damn good about it, and that's something.
And with that, we end the day with things looking like this:
That's the first two repair sections welded up. Sure they're not perfect, and sure that spot I'm pointing to with the filler rod needs to be touched up again, but man.... that is not a bad start for an idiot that has no idea what he's doing
Good times.
