Re: FOAM-- [CAD_CAM_EDM_DRO] Measurements to compare machines

I am a little hesitant to post this but as a service by daytime job company can supply Type 1 or Type 2 Polyurethane Grout with an agregate. This is marketed as HPRG (High Performance Rail Grout) and typically we will sell in bulk quanities, i.e. 5000 cu/ft. We do have it available in bucket mix kits which is about .6 cu/ft. The material in this type package is in the $300 to $350 per cu/ft (about 7.5 gal.) range. The kit contains the resin, hardner and agregate.

Hardness of the Type 1 is about 85 Durometer and the Type 2 is 55 Durometer. We use the material to anchor, electrically insulate and deaden vibration in embedded street car track. The material is very dead and very solid. I can supply photos if it helps.

Not trying to make a sales pitch but want to make you aware of the options.

Hi Mike and all:
      You can buy a gallon of epoxy that will mix with the stone to fill your
you tubes with from a company in Penn. if I remember correctly. Not
cheap so use a good mix of stone with small gaps!!

                                                                           Bill Thoms
