Bio-diesel Fuel / Re: Favorite source for methanol + potassium hydroxide
« on: February 18, 2022, 07:37:34 PM »
So I found a source for methanol, the cost would be $5 a gallon. But I have a half baked idea for an alternative. E-85 is readily available in my area and costs about $2.75 a gallon. Has anyone tried making biodiesel using ethanol instead of methanol? And would the 15% gas (petrol) in the e-85 make it better or worse?! My thought would be better because biodiesel has a higher flash point than regular diesel, so a little gas (petrol) would help lower it closer to regular diesel. Or I’ll blow myself up, not sure.

Hello, I have a DI 12/2 I’m kicking around making bio diesel for. A family member runs a restaurant and can get me all the veg oil I want. I’m just trying to find the best sources for methanol and sodium and or potassium hydroxide. Who would have that stuff at a good bulk price?

Listeroid Engines / Auto shut down, less than $100.
« on: February 15, 2022, 01:36:41 PM »
After looking at what Murphy brand auto shutdown components cost, I came up with an idea for an auto shutdown system that cost less than $100 to build. I’ve ordered the parts, just need to assemble when it gets here! It works like this:
My system uses a 48v battery bank and dc charging from my 12/2. The way the auto shutdown will work starts with a low voltage cutoff co trip board from eBay. This component is wired to the battery bank and can be set to close a relay at a certain voltage. For example of the volts are below 54v the relay is open (no current) if it is above 54v it closes (allowing up to 10amps to pass through it from the battery bank). The next component is a step down regular, it turns the 48vdc to 12vdc. Then there is a 3 way switch which has off, and the two on positions send current to a 12v 2” actuator in either polarity so you can move it forward or back. This is hooked to the fuel rack. The last component would be a kill switch for the system that cuts the voltage to the actuator when it is fully retracted. When you want to reset the system simply turn the kill switch back on and use the 3 way switch to extend the actuator back out (then be sure to leave the 3 way switch on in the retract position again). This should work and the components cost less than $100!

Listeroid Engines / Re: Filling pitted spots

Thanks guys, I’m not too picky but there is some pitting on the smooth outer surface of my flywheels and I want to fill those.

Hello, what is the standard procedure for filling pitting in the castings? After removing the paint and sandblasting my flywheels there is some pretty good pitting in some spots I would like to fill. Do you braze iron into them? JB Weld? Epoxy?

Listeroid Engines / Re: Muffler Through Wall Question
« on: February 11, 2022, 11:53:34 PM »
I likely going to have my 12/2 I beam frame bolted to the concrete floor in my shop and run exhaust through the wall as well. Does anyone have tips for insulating the pipe so there is little to no heat transfer as well as keeping weather out? I've installed wood stove pipes before, you use a steel box that keeps everything away from the hot bits and the pipe was triple insulated as well.

Listeroid Engines / Re: Import of Listeroids - Food for thought
« on: January 27, 2022, 05:25:32 AM »
IMO the best way to import these is not to import engines but parts. The question is when does an engine go from parts to an engine legally. Based on my conversations with cbp that is a very grey line.

If you want more technical information I’m sure he would offer it. He has responded to some of my questions.
Looks like he’s been running it that way (my first comment) for a while:

So the nominal voltage of each cell in the prime pack is 3.7 volts, so 13 of them would put me at a 48.1 nominal voltage. I’ve also seen some guys run them without bms, they just put low amp fuses on each string and keep an eye on them.
