The first stage was to weld a couple of hefty steel I-beams to the ceiling of our workshop, in order to make as rigid and massive a support as possible. This photo sequence shows this procedure. (We do accept that this support, although enormously strong, may not be absolutely rigid and massive, to the standard which Allais has specified for an isotropic support based upon his experience. It is not perfect, but it was the best that could be done at the time without constructing a purpose-built building or bunker, as described elsewhere upon this website. Yes, that is the next order of business!
