Finished the Fuel Taps. Lots of different set-ups and operations required. Did much of the work while still part of the parent brass rod. Cross drilling 3/8"(9.55mm)-
I wanted the tap levers opposed to eachother for access (in the off position), so had to be careful when it came to drilling through with the tapered plugs fitted-
.
The Tap's cam limit plates had to be soldered together, then to a stub of brass for machining to shape using a rotary table-
When as much work as possible was done, I cut them away from the parent bar and 'Silver Soldered' the pipe connection rods to the Tap bodies.
All the fiitings are for 3/16" (4.75mm) copper pipe. The tap tapers are 'pulled in' using the correct 'Thackery' coil spring washers and provides just the right amount of resistance-
A light polish and just need proper 1/16" Split (cotter) Pins to finish off. Maybe blend the joints. Happy with this first time job for me.
