What was next?? Oh yeah. The concrete fill for the base. There were some guys talking about damping and vibration even back in 2005. Some were using epoxy and various grades of gravel. I like it. Mass = stability right?
Problem for me is I could not afford the massive amounts of epoxy. Its not inexpensive. I looked for some other fillers that were less expensive. I went with concrete. At the time there were only a few suppliers of Ultra-high-performance concrete (UHPC). It was a new item then. And still is for construction.
But in 2005 there was a product that was close. HardBlok. An engine block filler for racers. It has some great thermal and mechanical properties so I used it. And it was with in my budget. Pics??
Prepping the base for the fill. Some solvent cleaning IS a must. Remove all the oils. I like acetone.
Then I taped off all the sections where I did not want the concrete to go.
More blocking with a simple cardboard box.
Some grease for release of the box.
Form in place and the concrete poured.
Form pulled..
Some spray paint to use up one of too many cans I have.
Fast forward. The concrete is still there. Havent use the Mill yet but the concrete is still attached. JR
