Today I picked up a lister VA on one hour drive, it's even running. I am thinking of passing it on only am wondering if I take it apart and give it a full treatment ore just to leave it as found. It's running but needs some cosmetics to make it look nice.

Lister, Petter, Blackstone diesel engines / new member start o matic chp
October 07, 2015, 03:53:24 AM
Goodday folks,
I have noticed that running big engines is not so populair anymore. Maybe i can start it up a little.
I am busy with making my own chp for about three years now. I bought from ebay england a start o matic 6-1 from a scrap dealer. I live in the middle city center of an old town in a very old house (300 years) and I have the engine indoors.
Very fast threw the developments, my bigest problems were exhaust noise and fibrations and just general noise. I bought a second hand freezing cell covered the walls with rockfon ceeling pannels and you can not tell if the engine is running. The exhaust I made a labyrinth exhaust box with the same rockwhool pannels and there is only smoke from the exhaust. No sound at all.
I am left with one huge problem, vibrations.
I have a 5/12 meter man cave on ground floor and a few years ago I got a new concrete foor with floor heating, due to it beeing an old house I could not dig deep enough to poor in the concrete I wanted so I am stuck with 10/12cm concrete. and you can feel the engine running. And in the living room you can hear the cutlery vibrating along (one floor up).
I have been experimenting a lot with rubber tyles, engine mounts. Extra weight . Its sort of excaptible but far from perfect.
I sort of made a decision to penetrate my new concrete floor with four concrete studs and put a serious heavy base on top but I am afraid that the thick clay underneath my house will transport the fibrations non the less.
It has been like that all the time, one step forward two steps back. But with this heavy engine and parts every idea takes a few days to try.
I have been threw all the balancing I could find on internet, beeing it an original lister with the extreme heavy flywheels is there any inprovement to gain you think. I think tommorow I will give it a testrun with normal 6-1 flywheels to see if it improves.
Now the engine is on a start o matic base and that is mounted on a very stiff steel base about two meters long 1 meter wide. Each corner of the base is resting on approx 20cm2 rubber playground tyle. This gave the best result i could get. Engine sorts of floats above the "rigid"concrete. At full load after one hour its almost acceptable but when you get two floors up in the bathroom your toothbrush is slightly rathling in the glass.
I could seriously need some good advice.
Kind regards
Bernhard
