There is a documented story of an automotive engineer showing up at a state fair booth where a guy was demonstrating an oil additive. they had a motor set up where two pieces of metal rubbed together and you could see the reduced friction when their product was added. The Engineer asked the guy running the booth if he would try 'his stuff', .... new pieces of metal were installed and this mystery concoction was added. To the amazement of the Booth Operator, he couldn't apply enough pressure to the disk to slow it down! The performance of this mystery stuff was off the chart, and clearly better than the stuff he was selling.
Here's my freshly poured floor, I added a step to my shop back door with the overage.
This mount system is a bit of an experiment. I've based it on how old logging operations used to set
their engines in a bed of clay. My Foundation Block is sitting in about 6 inches of clay.
I planned it so that once my floor was in, my crankshaft is at a comfortable height.
Prior to the pour, I had placed 1/2 inch plywood around the block, after the concrete cured,
I removed it leaving a 1/2 gap between the floor slab and the block.
Will post an update of how well this isolates the vibrations.
Long story short, I spent two weeks researching, cleaning off and aligning timing marks (three of them) and removing access panels and accessories. I would fix this sucker. After all, how hard could it be? Then as I was waiting for the courage to remove what I was sure was the offending pump a man rang my doorbell and asked if I had an Oliver for sale. He needed one. I told him the situation as best I could. He made an offer on the stipulation I put it back together in running condition so he could load it, which I accepted and which I did.
