The object at the time was to be able to maintain without having to rely on someone else who might clean the mirror of the old aluminium reflective layer and in the process damage the surface. As such it was not important to me how long the process would take and the trick was to invest as little as possible: all up I spend less than 10% of buying through normal channels all the parts. Most of the costs were for buying a new glass dome, seals, oils and a variac for controlling the filament.
The mirror was made from zerodur which came from Zeiss in Jena. Darn hard stuff.
