What a day!

Two entries - would you even believe it? Yes - today has been exceedingly eventful. What with no electricity in the morning followed by intermittant electricity, I am much more inclined toward gas as well as my 120v plugin.

After breakfast/lunch/whatevertheheckitwas, I left to go to work. Arriving, I found the normal rooms locked up and the lights out. Then I found the boss. Apparently he'd tried to let me know that work had been cancelled for today but his letting me know had been to ring my phone and leave no message. That wasn't particularly helpful but anyway as nothing could be achieved at work, I turned around and headed back home, stopping off at the barbers on my way. It had been a couple of months since my last haircut!

Arriving home, after checking out the microwave I set to, working on welding the final patch over the hillbilly cable compartment disaster area. It took a while to trim the steel to shape and I deliberately undercut it this time in order to avoid the warping problems I had last time. 

Welding with 6011E 1/16th rods used a lot of rods and I had major problems - as before with burn through. In the end and because I ran out of 1/16th rods I turned to 3/32 rods. What a difference - these were and this is extremely counter-intuitive much easier to weld with. I began to fill the gaps where I'd undercut the steel but before I had quite finished, the daylight escaped on me. Had I had another couple of hours of daylight, I'm sure I would have finished the task.

Using the 1/16th rods I never had a problem with the welder shutting down to cool down. With the 3/32, rods I'd manage about two rods before the welder would overheat and need to cool. It has a 20% duty cycle. If I'd spent more on the welder I would not have the problem. On the other hand, I am happy that I didn't pay for more than I need.

By the time I had to stop due to darkness, I'd welded about 75% of the edges. I applied some black bumper spray since my Rustoleum anti-rust spray and my Rustoleum self-etching primer sprays didn't want to work and since I didn't want to use a paintbrush. 

As can be seen, I haven't finished welding the bottom left now the lower left side. My welds aren't pretty but they do work. I'll be glad when this operation is completed!

As mentioned before, I looked at the microwave. I pulled it out and wire-brushed the rusty parts inside. The more rust I removed, the more I found. The paint just peeled up and revealed yet more rust. It really wasn't very impressive for a microwave that I purchased in November of 2011 and used until May of 2014 then stored in a dry location! I don't think 30 months is a good life for a microwave!

Anyway, I kept working on the rust with steel brush and scraped the paint away with a plastic paint scraper. After a while I noticed that the rust wasn't surface rust. It was rusted through in places. How on earth is this possible? There was so much rust that repairing the microwave just seems pointless. Certainly I can deal with rust. Looking at the holes in the bottom of the roller recess, it just seems to me that the microwave is beyond repair.

Sadly, I took the microwave out of the bus. I'll have to replace it with something else. So, for the moment it's sitting on the ground awaiting disposal or recycling.

I had hoped at least to get the electrical inlet hole made but still, I have made progress. Indeed maybe I might have made faster progress had I used 3/32 rods from the start. I didn't know that at the time for I am but a self-taught amateur welder.

The new monstrosity emerges

Just when you thought it was safe to let the women and children out on their own, my monstrosity emerged from the capable hands of my Harbor Freight 70A welder. Starting was much delayed due to my looking for a way to hold the pieces in place. I considered riveting but couldn't find my rivets. Then I tried to bolt the pieces together but the 1/8th drill bits all seemed pretty blunt. In the end I retrieved a tiny G-clamp from something I'd put together several years ago that utilised a G-clamp. That did the trick! It held the pieces together while I welded them.

There were setbacks along the route such as letting the welding rod linger too long and burn a hole in the steel I was welding. That delayed things as I had to make concentric circles, waving the welding rod around the hole like Harry Potter's wand while I built up the steel surrounding the hole until the hole was filled.
It's not quite rectangular but I'm not bothered - the simple act of riveting it underneath the bus will pull it straight. Once it's riveted into place I might weld it as well. I'm not sure about that yet though.

I have't painted where I welded yet as I need to put sides on the compartment and the simple act of welding burns the paint off. Watching the paint in flames was quite entertaining! The original plan was for solid sides on the compartment. The power socket could go underneath the compartment. That would simplify things considerably. The cable needn't go through any complicated routes.
Looking around, I found some steel mesh. It looks ideal to use as sides. That would have the advantage of allowing air to evaporate any water that seeped in through the compartment door. The whole point of the compartment is twofold - firstly to top squirrels from eating the electrical cables and secondly to provide somewhere to mount the electrical inlet. It would be nice to keep spiders out but they get in anyway.

Checking the bodywork steel, it seems to be the same thickness as the vast majority of the lightweight sheet steel that I already have. It should not thus be a problem to fill the cavity left in the bodywork by the hillbillies. Certainly moving the welding rod as swiftly as Harry Potter's wand means I should be able to weld thin steel. My welding has definitely come a long way since I attempted to weld two steel conduits together and burned right through them.

Tomorrow's plan is to continue with construction of the compartment and possibly to demolish the old wooden compartment as well as removing the aluminum compartment door. Like as not, there'll be some hidden nastiness there that'll need to be dealt with. I might even need to move the bus closer to the power supply in order to do more welding.

I can kinda sorta see why people sniff at the cheap Harbor Freight welder. It is pretty slow to weld with. On the other hand, I'm not in any particular rush. If I can get the breaker box compartment completed by the time I return to work on Tuesday then I shall be elated.
