… two wheelbarrows up and running today.
I started off with the yellow wheelbarrow. That involved removing the old wheel, cutting down the axle of the wheel that I bought on Saturday so that the axle was the correct width, sleeving it internally with a length of copper tube, pumping a pile of grease up the inside, cutting down some threaded rod to the correct length to make a spindle, putting washers on the inside of the mounting brackets to keep in the grease on the spindle, and then passing the threaded rod through and bolting it onto the wheelbarrow through the holes in the mounting brackets.
All that then remained was to pump up the tyre with the portable compressor, and that was one wheelbarrow finished.
Then I turned my attention to the old B&Q wheelbarrow. The inner tube kept on going flat with that, and having dragged it through the wet concrete when we were concreting the parking, concrete worked its way inside the flat tyre and it’s ruined the tyre and tube.
And so I dismantled the wheel, took the tyre and tube off and filed them under CS, and then went in search of the wheel that I bought about 3 years ago. It took about an hour to find it, and when I measured it up for the wheelbarrow, I found much to my surprise that I’d already cut it down to size before.
So why hadn’t I fitted it?
Anyway, that needed sleeving on the inside and once more an off-cut of copper tubing came to the rescue. The spindle was made of threaded rod (I’d made this some time previously) and having packed the sleeving with grease, I then went to assemble it.
And then I found out why I hadn’t fitted it previously.
The fact is that the profile of the wheel and tyre is too high, so that there’s not enough clearance between the chassis and the bucket of the barrow. And so I’ll have to order a new tyre and tube, and I needn’t have bought the wheel that I did on Saturday.
Still, you live and learn.
I was on my travels during the night. I had enrolled on a computer repairing course with Terry, and we had started to learn a few basics. On one particular section, Terry remarked that he had once actually thrown away a computer that had suffered from the problem that we were resolving, because he thought that it was irrepairable. At the end of the day we all went outside and I went for a wander along the road between the cornfields and ended up at the border with the USA. Here I met up with pf all people, Zero (who accompanies me quite regularly on my nocturnal rambles) and we walked around chatting for a while. We then needed to go back into town but she said that she was tired and asked if we could take the bus. There was a bus – a school bus – waiting and so we climbed aboard but the conductor told us that this bus was going over across to the USA and so we needed to alight and wait for another.
After breakfast I carried on with my studies and I seem to be doing okay according to a test that I took this morning.
But here’s a thing. For about half an hour or so, we had about 21 amps of electricity going into the dump load. And while that’s not particularly exciting, the fact is that the cables were stone-cold as far as I could tell, and the temperature had risen by just over 5°C. Usually, for about 20 litres of water, a rise in temperature of 1°C in the water needs about 8 amps of current, and so it looks as if I’m getting twice as much current going into the water compared to previously. That’s how much must have been dissipated in heat down the cables.
Of course, it’s early days yet and I need much more current than this to prove the point, but at least it’s progress of some sort that there was no energy loss to heat down the cables.
I’ve tidied up a pile more downstairs and the table is looking clearer and clearer. I’m finding tons of stuff that I’d “lost”. But tomorrow is a Bank Holiday and that means a day off. When I start work on Thursday, now that I have a wheelbarrow I can start to move the stuff from out of the way at the front of the house and if the weather is good, I can cut up a pile more wood and move it much more easily.
