Trevithick Dredger Engine- Supports
These are the boiler supports for th Trevithick Dredger Engine, which need a little more finishing.
As you can see my CNC mill is working nicely. The slow feed rate is because the brass is just super glued to the mounting base and I did not want to risk it coming adrift.
And I have also been working on the 6″ vertical boiler. The brazing with silver solder is almost finished. I have been redoing some of the joins, and can now get the pressure up to 200psi. There are 101 soldered joins in the construction (so far), so I am not too upset that a few of them were not perfect and required a redo. SWMBO was wondering about the bills from the industrial gas supplier. I have used several fills of oxygen. Totally abandoned acetylene and using propane now. It delivers more heat (at a slightly lower temperature), and much less costly.
