Yeah, the paint job really does pull it all together! The bus interior has otherwise been done (enough) for years. Now I'm playing with mechanical things a bit more. Stopping oil drips, tightening steering components, smoothing suspension and so on..

I also started dinking around with a battery charger rig for those cloudy months again:




The charger consists of a snowblower (obviously ), a handful of pulleys and belts I had kicking around and a 90vdc treadmill motor.

I tried a similar thing last year, but I made the mistake of using a 2hp 2-stroke motor that I extracted from a busted up 900w Chinesium grade generator. You've probably all seen the generator I'm talking about at your local cheapo tool stores. They are shipped across the ocean, rebranded and resold all over the place.


I found mine at the dump. The engine ran fine, but it was loud and hopped around all over the place. Not a great candidate. Had to scrap that direction.

The snowblower, on the other hand, is a great candidate! It's self-propelled and has a new 6.5hp engine! I can't say for sure, but it seems that using that 6.5hp engine for dual purpose may actually be better for it in the long run. As it is now, the engine only gets used a couple dozen times in the winter, then sits around for the rest of the year. Using it more frequently should keep the bearings happy, cycle the old fuel through and remove condensation from the oil.

Now, one option currently is to use the 8000w generator (which I typically use for welding) and a battery charger. This turns out to be quite expensive. The generator has a 420cc engine that is turning at 3600rpm. The 6.5hp 196cc engine, on the other hand, only needs to turn at 2000-2200rpm to pump out a 60a battery charge.

The treadmill motors are nice for power generation because they are higher voltage than an alternator and use permanent magnets instead of field windings. Usually the voltage is somewhere between 90-150vdc. At those voltages it can be charging 100ft away with minimal line loss. My MPPT charge controller can accept up to 100vdc. As long as I get the pulley ratio correct I can keep the motor/generator in the happy spot.

However, the little treadmill motor that I had salvaged some time back doesn't have a shaft-driven fan! How silly. It's not rated as heavy duty as some of the better treadmill motors. So I had to rig up an auxiliary fan to keep it cool. The other day that fan stopped working without me realizing it and the treadmill motor/generator was smoking Whoops! I'm on the prowl for a heavier duty motor.

Something like this would be nice:



I'll be keeping my eyes open!

I have been considering something similar using one of the Chinese Yanmar l100 clones, a PM 12si and the bracket found here: https://theepicenter.com/emergency-p...generator.html

How has your charge controller worked out in this application?

frig yeah.. a little diesel would be great. Do you know how those little Yanmar's do at low RPM?

The charge controller has been holding up just fine. It's a cheap Tracer 4210rn MPPT charge controller rated for 40 (or 45?) amps. However, it wants to pull up to 60a when the amperage is available for the bulk charging. It seems to do that fine. The giant heat sink only gets warm to the touch.

Wow! Cool bus! what a strange paint job I wish mine had that extra 1 or 2 feet that yours seems to.

So long in the making, but I finally slapped together the WVO/WMO centrifuge system prototype (click the image to see the video):

Well, well, well! I figured out the cause of the recent drop in power!




^ That is the harness for cylinder 5's glow plug and injector.








^ and here's the valve cover gasket.

I put an order in on Rockauto. Should get 2 new gaskets and harnesses by the end of the week!
