A plank? Really?

What with working from 8 til 4:30 with no lunch break and having not slept well the night before, I was exhausted after work. Thus, today's significant achievement was solely to visit Lowe's to spend $38 on yet another plastic plank.

Arriving home, I measured the soon to be shower base at 36 inches or rather, slightly under. I cut two 36 inch planks and one 24 from my 8 foot plank.

Tomorrow I shall trim the 9 inch wide planks to 7.5 then make the ends match and trim the ends so that the tub fits well into the mount.

Looking around Lowe's, I didn't get any inspiration for alternatives. The sole thought would have been treated 7 ply the same as I used for my toilet lid. That would have required copious quantities of brackets to secure it. The plastic planks solution can simply be glued to the PVC floor. I might screw the end pieces together but they'll be glued too.

I didn't buy more than just the plastic plank because that'll take me a lot of tomorrow and when that's done, there's the closet chain to erect and the breaker box to install. There's more than enough to keep me in mischief until the end of next weekend!

Thinking about power, I thought I'd come up with the final solution to the electricity problem. I remembered a gizmo that could be fed butane, hydrogen, propane or methanol to produce electricity. It had no moving parts. Hunting for it I kept finding references to products about to be released, products that had generated large sums of crowdfunding in the past and some very expensive cellphone chargers. I found nothing that could produce even 200watts.

Reading further, there was a Forbes article about the total failure of fuel cells to take off. It seems the gizmo is called a fuel cell. Reading yet further it transpired that they're relatively simple devices that could be built with very few tools and components. The problem is that platinum wire is needed in large quantities. That's why they have never taken off - nobody will pay the price when cheaper albeit Heath Robinson affairs are available in the form of generators.

Power generation keeps returning to wind, solar or generator. Solar is just horribly expensive. Wind is cheaper but pretty awkward as the generator needs to be mounted then unmounted for travel. Generators seem to work out as the most economical option.

Plastic planks and other thoughts.


Now the shower base is not sitting in the drivers seat, its possible to see the seat! There's stuff left to move before I can drive it though.

Speaking of driving, a letter arrived from my insurance company reminding me my bus insurance is due in September. The problem is that it was sent to my old address. I have no idea how many times I will have to tell Progressive that I've changed address. I have told their head office, adjusted it on their online system, told their local agent and yet they persistently get it wrong. Perhaps I'll change insurance companies?

Meanwhile, I cut up my remaining plastic plank to use for two of the four sides of my shower base. I need to make the base solid enough to hold the shower pan in place. The idea is to use plastic planks and simply glue them together and glue them to the floor.

As the plank is not wide enough at 7 inches, I had to cut it into 7.5 inch sections to glue together to make a 7.5 inch wide section. I thought after that since I need more plastic plank to complete the mount, it might be better to buy a treated wood plank. If it rots then I can replace it but that might be a long way in the future. PVC planking is most definitely not cheap! Wood, on the other hand, is far less expensive!

I glued almost 3 feet of plastic plank together. At 7 inches wide, that's about 28 inches. I have reservations about the strength of the glue. Indeed, I'm giving serious consideration to simply using wood planking, painting it and hoping for the best. The plastic wasn't wasted as it was all offcut anyway.

I might pick up wood plank tomorrow, together with some 30A cable, 15A cable and some conduit. It's time to get the electrics completed so I can get my bus registered as a motorhome. The original idea had been to have 50A cable but it seems hard to obtain. I can always change cables later!

Interestingly, Eric in Canada has found that there are a lot of homes now being registered with no electricity. http://lesguis.com/wp/?p=4927 That's interesting and makes me wonder how much of an issue my incomplete plumbing and electrical system will be in terms of reregistration.

Behold - the shower base!

Certainly it is a 24x46 concrete mixing tub from the farm supply store but it's new purpose is as my $18 shower base.

It's small enough that I could wedge it against the wall and have a ton of space. That might lead to mold however so that's not what's going to happen. It is going to go roughly where shown, held in place by a mount made from PVC planking.

After installing the bathroom floor, I had enough PVC plank left over to make two of the four edges from the plank. Sadly, I'll have to pony up for more but it'll be worth it! The corners will need special care but this is what the corner looks like without special attention. Eventually the corners will be squared to perfection.


Meanwhile, in the hunt for a 12v fridge, it transpired that the 12v heater/cooler fridges are built out of standard coolers with a single Peltier element. The Peltier element is very interesting as it transfers heat from one side to the other when power is out across it. The maximum cooling is 20C or 35F below ambient. That, however is a great playground for experimentation with water cooling systems etc.

Coolers are pretty cheap - I picked one up for $15 new a week or two back. Peltier elements are about $5 on eBay. CPU heatsinks and CPU fans are also pretty cheap. With a little care, a 12v fridge can be built for under $30.

Peltier coolers don't keep things very cold but they should be fine for prolonging the lives of fruit and bread. There was an article I read about one fellow who built an air conditioner using a Peltier element. Apparently it worked well enough. Again, given a water jacket cooler, lower temperatures might be achievable.

Given the horrible efficiency of solar panels I'm giving thought to building a vertical wind turbine. I'm nowhere near ready for it yet but I know exactly how to build it.
