Tomorrow I start silver brazing the 6″ vertical boiler.
But today I started machining the bronze end plate of the Trevithick Dredger Engine.
First I prepared a 100x25x200mm sacrificial aluminium block to hold the expensive bronze disks which will become the end plate and flange of the Trevithick boiler.
Earlier I had called on GSMEE president Brendan, who happens to possess a CNC laser cutter. I had discussed the possibility of CNC cutting some gaskets for the steam pump which will be made for the 6″ vertical boiler. “No Problem”, said Brendan.
