Trevithick Dredger Engine. Finishing the flat end plate.
Today I brazed the inspection hatch to the flat end plate. I did have some qualms about using the shape which I hade made, because it is quite round, whereas the example in The London Science Museum is more elliptical with one edge shaved off, and bolts which are irregularly placed around the perimeter. But it is done now. I admit that I was influenced by reactions from club members who were complimentary about the hatch which I had made, picking it out for special mention when I took it to yesterdays meeting. And if I do not like it later on, I can remove the surface and make another one, more wonky like the original.
Before brazing I made a firebox door and surround, and bolted it to the end plate.
The door is cut out, but yet to make the hinge, catch and latch.
And just to remind you what I initially made, according to the Cain/deWaal plans…
