Still playing catchup on my posts, I was pretty thrilled with progress when I got things installed with more afternoon to kill on Thursday so I decided then that I was going to go after that head bolt as well.
I figured I'd do it by drilling the heads off the other head bolts I have and then welding them onto the stuck bolt in the engine. I've got enough "nub" sticking up to do so and the heat applied should be localized enough that I can heat the bolt a bit without hurting the aluminum so I toss a bolt in the vice and got about this far:
Before I started wondering if there wasn't a smarter/easier way to be doing things... It turns out there was. The idea now is to find three nuts in my coffee can that will fit over the shank of the bolt with minimal effort, and weld those to the nub instead of wasting a bunch of time drilling things that don't need drilling.
These were my candidates:
Pictured above are the two pieces I'll use as test units, and one nut to weld on to the nub itself for the real run.
Welding the nut was both easier and harder than I thought. It's easier in the sense that it wants to melt together when I tell it to, it's harder because I need the weld to go deeper than the nut is wide (if that makes sense). I'm almost certain that I'm not penetrating anywhere near as deep as I need to be, but I go forward with the real-deal welding on the truck anways.
Now, I've learned my lesson about cheater bars and breaking stuff, so I'm going to use a freshly purchased pneumatic impact gun to zap this thing off. Out comes the air compressor, and out of the box comes my new air gun.
This has GOT to work, because it ALWAYS works. The hammer smacking action of this beast doing what it does is going to break up that carbon that's coked on that bolt and I'll have it out in no time.
The gun has 4 settings, and I decide to set it at its second lowest. Once the compressor gets up to 110psi, I pull the trigger for all it's worth and BRDRBRDRBRDRBRDRBRDRBRDR goes the gun, but the bolt doesnt move...
The compressor's dropped a few PSI so I let it catch back up and up the setting on the gun by one notch.
BRDRBRDRBRDRBRDRBRDRBRDR goes the gun, and the nut doesn't move.
Ok, maximum setting, 110psi, here goes:
BRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDR (inhales deeply) BRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDRBRDR!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Goes the gun, but nothing moves... at all.
I'm thinking quick at this point. I cant afford a more powerful gun, and I'd never use the darn thing even if I did buy one. But tire shops always seem to have beefy lug slinging units on hand, maybe I can visit one of them.
I have a liter of plum squeezings still in my cabinet from last year, so I pour about a quarter liter in a bottle and toss everything in my car and high-tail it to the nearest tire shop in town:
When I get to the shop the door is unexpectedly locked. I'm right in the middle of shifting things from one hand to the other while stepping back to look for a sign that might say when business might be back when the door unexpectedly opens. Of course, the bottle of plum squeezins picked that exact moment for the stopper to pop out so a little alcohol spilled on my hands while I'm simultaneously trying to greet the employee, stop spilling alcohol, get the stopper back in the bottle, and explain what I'm here for and what I need. I think I could best describe my behavior as an doc Brown, with a bit of Rick (from rick and morty) mixed in.
But, it turns out that the employee had a good sense of humor so I left with a real-deal beefy ass "Ingersoll Rand" unit of tire shop variety and without my quarter-liter of alcohol.
No messing around this time. I crank the Rand unit up to its maximum setting, pump the compressor up to 120 psi, aaaaaaaaaannnnnnnd.
(come on, you know where this is heading)
Drat and double drat.
Told ya that penetration sucked. I'll work on that more later.
First, I return the borrowed tool and show them the broken bolt. We all have a good laugh, and they say that when I get a new head welded back on to come by and I can borrow the driver again.
Time to regroup and formulate a new plan.
