Bio-diesel Fuel / Expain to me why you bother to make bio diesel
« on: August 18, 2017, 11:07:38 AM »
I'm just curious but why go through all the effort to take veggie oil and convert it to bio diesel? Why not just take veggie oil and add a small amount of gasoline so the specific gravity is that of diesel? What am I missing?

Generators / Glyptal vs. Generic?
« on: August 07, 2017, 01:23:52 PM »
Getting ready to tear my ST gen head apart. Any recommendations as to using a generic "Red Insulating Varnish" as opposed to the real deal-Glyptal?

Hey Guys, I have a Perkins 402D engine that drives a 7.7kw ST head. It is mounted on a 2x2 steel frame. I've gone through 2 iterations of different mounts and neither has reduced the vibration. At first I tried something like this:

As I tightened the belt for the 2 pulleys these things just made a 90 bend! It was then that I realized I forgotten about shear so I then went to the Karmen Rubber page and calculated the correct (or so I thought) isolation pad. These did nothing

I know this is not rocket science so if anyone can help I'd greatly appreciate it. I'll post some pics later... after I figure out how.


Everything else / Oil tank advice needed
« on: November 04, 2012, 12:23:32 PM »
Hey guys, I'm s..l..o..w..l..y getting my diesel back up system together. Currently I have a multi fuel furnace that will burn oil or wood so I have a 275 gallon oil tank in my basement. I just bought another and have it mounted outside. My plan is to have 3 tanks. This will give me a large supply of fuel at any given time plus I get a discount when I order more than 300 gallons of oil at a time. My 2 extra tanks will be outside, uncovered. I am somewhat concerned about getting water condensation in them and I know IPs do not like water. Do I have to worry about condensation in my tanks that I will use in my diesel or am I just being anal? I have a Diesel Craft Centrifuge but so not see that was a practical solution.

Hey guys, A few years ago I bought a Listeroid 6/1 and a Redstone from John F. (Woodnstuff). I welded some frames for them and packed them away in my garage. My plan at the time was to store them for 10 years, retire, then build my retirement home in southern Virginia and use these 2 as back up power etc for an off grid house. I also bought a few extra heads for the 6/1 as well as the "complete" spare parts package from Central Maine Diesel. Well... Now I'm seriously thinking of buying 2 of the 20 hp Laidong engines from John F and selling the 2 previously mentioned engines. I like the idea of having 2 of the same engines, side by side as my power source ( commonality of parts etc).

What do you all think? Are they worth selling? If so.. how much would be reasonable? I have no intention of making a profit, just selling them for fair market value or a little less.

Any thoughts/comments appreciated.

Waste Motor Oil / How to adjust pH of WMO?

Can someone tell me the best way to adjust the pH of my WMO. I have a batch that I plan to centrifuge soon. Thanks, Randy B

Generators / Help me pick a replacement bearing for my ST Head
« on: December 15, 2009, 05:12:22 PM »
Hey guys, I'm going to be buying some replacement bearings to keep as spares for the various ST heads I have. What do you all like or dislike? As far as RS- (rubber) or ZZ- (metal) I'm leaning towards the metal sealed bearing as oppossed to the rubber sealed bearing. Any pros or cons?

Also.. Anyone like a particular manufacturer? I'm not sure if that matters since all bearings are probably made in China

Thanks, Randy B

Generators / Who Glyptal's their generator head?
« on: December 08, 2009, 08:10:20 PM »

Other Slow Speed Diesels / How to mount the Cat Diesel?
« on: September 03, 2009, 05:35:26 PM »
Anyone given much thought as to how they are going to mount their Cat diesel?. I'm thinking of making a base out of 2x2 box metal to fit the engine, generator, battery etc. I just haven't decided on how to mount the engine to mitigate vibration. Any thoughts?.....  Randy B

Other Slow Speed Diesels / Cat/Perkins Manual
« on: August 26, 2009, 03:01:17 PM »
OK, This is not a service manual, but at least its a start. Its the Rigmaster website with info on their APU system. It includes info on our little engine... just scroll thru!...  Randy B

Other Slow Speed Diesels / The little CAT diesel
« on: August 24, 2009, 11:33:38 PM »
Hey guys, I have one of the little Cat diesels from the SurplusCenter. I was planning to put a stub out with a 6 inch shaft on mine and attach a pulley from George at Utterpower ( and run it at about 2500 RPM). I know there was talk about the engine being able to take a slight load on the bearing but does anyone see a problem with one of the Uttepower pulleys?.. they are pretty darned heavy. I 'm concerned it might be too much weight hanging off the shaft!...Randy B

Listeroid Engines / Anyone add a glow plug to their 6/1 ?
« on: August 21, 2009, 09:23:07 PM »
Anyone add a glow plug to their 6/1? I'm curious because Central Maine Diesel sells one and I figure that when I get old (like 110) it would/should make start up a breeze, but I'd like a little input before I buy one.  Randy B
