Dave and Dave - both cool posts!  David V, does the concrete distort when it dries?

[FJ and G]

Hi Jim, The concrete doesn't appear to distort, but that's irrelevant. It is only displacing RTV that would have been wasted. Think of it as the outer mold. The RTV will be the inner mold.

Here it is poured. This evening I’ll strike the mold (it takes 5 days to cure completely, but I’ll chance it as it’s been about 2.5 days). I’ll then proceed with the rest of the project and describe it here.

I struck the mold, turned it over, applied vasolene to the concrete for release. See the 2 registration marks left by the 2 clay lumps. The upper half of the pour fills these in and will be keys to align the mother mold of concrete.

The 3 clay pieces sticking up will be used to de-air and pour RTV into the mold once the mold cures. I’ll likely do this on Friday.

The mold didn’t quite fit exactly back in the box so I lined the edges with clay. Incidentally, the non-drying clay used for the registration marks felt strangely dry. Apparently, the concrete succeeded in sucking the moisture out from it.

I’ll post success for failure results.

The other molds are coming along. Here’s half of the 2-part chassis mold weighted with BBs. I’ll pour the resin this evening for it.
