A Gas Burner for the Trevithick Dredger Engine
Last post I asked if anyone could guess what the redgum pieces were going to be used for.
Today I turned up another piece of the puzzle, which might be helpful..
And look where it fits..with a 1mm gap.
Just to bend a piece of annealed brass in the press. Hmm.. I wonder where this will fit..
Ah… now I see…
Silver soldered. Ceramic burner needs to be cut. Diamond saw? Maybe I will try the bandsaw..
Well, that is surprising. I expected that the ceramic material would laugh at the bandsaw blade. But no problem at all. Like a hot knife through butter.
After sawing the burner roughly to size, the edges were given the curved contour with a belt sander. Again, easy as. It is sitting in position, but needs the edges sealed with some heat resistant goo. Any suggestions?
The gas burner will be easy to remove if I ever run the Trevithick engine on coal. I am still fiddling with gas jets, hoses and connections.
