i asked what if any listeroid your running and how much.
This is a good question and I want to expound on it. I love engines, have since I was a kid.
I have never in my life had the opportunity to really _work_ a classic type stationary flywheel engine. There are a number of reasons for this, not one of them related to lack of desire. That has not stopped me from purchasing, working on them, running them (not under real load, or in a real working application)... You see these type engines at shows, guys have them skid mounted and set up on trailers to make them transportable.... But that is not a working engine, it's a show engine.
Now... Finally... For the first time in my life I have real reasons to work a classic design flywheel engine. Reasons important enough to justify the time, expense, and effort in doing the job right... The first time.
I looked at my inventory of engines, and I sold them for cash. They were show engines, not large enough to generate sufficent power, and parts, parts, parts... You should not take a collector engine and put it to work as a prime power source if you cannot make or obtain replacement parts at a reasonable cost.
I researched... I like the Lister design, I have seen orginals running. I like the Witte design, I have seen them running... Other brands of flywheel oilfield engines interest me a great deal, I almost bought a Witte configured as a genset... But from a cost and parts availablity standpoint, the Lister clones from India are hands down winners for a real working engine of this class and type.
Next up, after the decison to purchase was made... The engineering requirements to properly _work_ the engine on-site were researched. Now there are two schools of thought about this (as if you don't know having read down this far)... But the people who advocate and employ flexible mounting strategies for these type stationary engines are not supported historically, they are not supported in the factory engineering specs (these are people who buy things and throw away the operators manual apparently), they are not supported by modern engineering guidelines where stationary reciprocating equipment mounts are specified.
The right way to do this job is exceedling clear. I will have a concrete truck come on site and pour my equipment blocks after I have excavated out to specs and placed in the rebar, isolation padding, and formed everything up. It's that simple, even if it is a lot of work and it does mean an additional expense. This is a permanent installation, and I am going to work my engine _hard_
There is nothing at all new, or controversial, about stationary engine technology... It has been done, and done, and done for years and years and years. You can pick up any good engineering manual or search on-line to get exact equipment block specifications: block size, depth in the ground, footprint dimensions, material specs; everything is out there in print from accurate, well researched, and historically proven engineers.
Then... You have the other school.
