Re-building+the+16+inch+TRO+pitch+lap

Medium pitch supplied from Jon Owen was used

The pith squares were 10mm thick. This was done using 10mm strip wood fixed to a flat surface.

Grease proof papaer was used to prevent the pitch sticking. Parchment papaer (used in cooking) would probably have been better and would not have fallen appart as easy as the grease proof paper.

The pitch lap was already had a convex curve to match the mirror. A thin layer of pitch was bruched onto this as a base to melt the squares into.
