Trevithic Dredger Engine – New End Plate

by John


This was my first effort at making a boiler end plate.  It was OK, but a lot of my hammer blows left dents which looked pretty ordinary.


I tried to improve the appearance by polishing, but that just accentuated the dents.

The boiler inspector passed it, but I coud see that he was not too impressed.  And neither was I, so I made another one.  This time I made male and female wooden forms, annealed the copper disk and pressed the domed shape.  Then re-annealed and hammered out the flanges.


It was worth the extra effort No?

I will keep the reject part.  Might be useful for something, and will remind me to be more careful.
