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.
