Me with the
N&W Gang
The garage I was at for the last few days is a really special place. Conley Newsome is the owner, and his son David and daughter Anita help him run the business, along with CC and his brother-in-law Beak (Anita and CC are missing from the photo. Conley is an 8 time motorcycle hill-climbing champion (here he is in a Sports Illustrated article), and is tough as nails and strong as an ox – he broke apart some of the pipe fittings that I was having trouble with. Whenever I had a question about something or needed to borrow a tool, they were always there to help, and the coffee they brewed in the morning kept me going. I am hoping that their business might actually pick up because of the economic downturn, since people might start fixing their old vehicles instead of trading in for new ones.
I got to see a little bit of Columbus, including the COSI science center, thanks to my school friend, Sam. And there was a really nice yard sale nearby that I stopped at twice, where I bought a little hand held vacuum for the bus.
Well, do you want to see what working on the bus? Here is a little photo journal of the work I did this week at N&W, including hooking up the ‘slobber tube’ collecting pan, reinforcing the waste water tanks, and putting together the veggie valve assembly.
One of the reasons to go to a garage is that you can put the bus over a pit or up on a ramp, making it much easier to get underneath of the thing. This particular ramp actually tilts back when the bus gets on it – it is a peculiar feeling when the bus starts tilting back. Once the bus was up there we ran it for a while to try to see where the oil leak was (the engine is hanging off the ramp at the back of the bus). We thought that the leak was just coming from the slobber tubes, which are designed to drain oil out of the air box. As Sam put it, the bus ‘sweats oil’.
Slobber tubes and collector can
Well, what do with someone who slobbers too much???
No guesses? Well in this case the bus was definitely slobering too much, and since lots of people with these buses don’t like the idea of leaving a trail of noxious slime behind them, there are special kits that will collect the oil and also prevent it from going back into the air box which can be bad. I was able to remove one of the old tubes easily, however the other one was directly beneath a big metal compressed air tube, so for that one a just extended the existing tube. Then both tubes clamp onto the drain box. You could do this using a milk jug too, but it doesn’t look as good, though milk jugs are very cheap.
Of course, I will still need to drain the can whenever it is full, but I can recycle the oil properly instead of leaving it to runoff into our already too-polluted waters. You should see the gigantic catfish that Conley and his grandson caught in the pond right next to the garage! These guys know how to run a green garage.
Gray water support
Here is a very exciting picture of the new support I put in for the gray water waste tank. You can’t see the tank – what you see is the drain line for the tank, and the thin steel ribbon I added to keep it from sagging down. The bus has two 50 gallon waste water holding tanks, one for the two sink drains (gray water) and one for the toilet (black water). In the future, I would like to try to recycle the gray water so that it is used to flush the toilet, since that water doesn’t need to be clean for that purpose. Daniel had actually set up this kind of system at the Flowershop (Daniel appeared in some of the very early posts here). Can you imagine how much water we could save if every house had a system like that? And it is not all that difficult to setup.
Every night in Columbus there were beautiful sunsets and beautiful moon-rises. Here is a picture of the bus where I was parked most of the time, in front of the garage’s ‘wrecker’ tow-truck. Well, no towing for me this time! (Knock on wood.)
The bus’ paint job is supposed to represent the sun, the water and the sky – one reason I like this picture, because you can see the colors of the bus in the colors of the sky. Soon we will start putting murals of molecules, cells, and ecosystems on the blue parts of the bus. The idea is to eventually use the outside of the bus as a teaching aid.
Valve assembly
Valve (dis) assembly
The first two photos here are the valve assembly that I diagrammed in an earlier post. In the first picture you see how I’ve disassembled it, in the second you see it put together. The metal rods in the first picture get covered by the black blocky things in the second picture – the blocks are solenoid electromagnets that pull up on the valve stem that is inside the rod, opening the valve underneath. Depending on which of the valves are turned on, you either use vegetable oil or diesel, and you can also choose where the unburned, ‘return’ fuel from the engine goes. This allows you to put diesel in your veggie tank if you would like to dilute it before burning it. The fifth valve is ‘magic’ – but since this is a science bus I shouldn’t talk about magic, so I won’t.
Veggie system installed
Finally, I stuck the entire assembly into the engine compartment, in about the only free space there is, which happens to be a very inconvenient space for working! But after some fiddling, I got everything connected and the thing bolted onto the firewall (that’s the metal mesh in the background).
I’m not showing you pictures of the electrical system, which I also did a bunch of work on. But if you thought pictures of a bunch of valves stuck together were boring, imagine photos of a mess of dull colored wires. I’m just not a good enough photographer to make that look at all compelling… yet!
Spending the night near Cleveland, but I hope to make it to Ithaca by tomorrow night. I prefer not to drive at night if I don’t need to, and I’m not in a big rush right now, which is a nice change! So when it got dark, I found a place to park, lit a fire in the wood stove, baked an acorn squash, and enjoyed a beautiful fall night.
