Saturday's work. The fittings either side of the regulator valve needed a bit of a clean up and deburring and to be drilled out to 7mm for good steam flow. The ball valve is 1/4" BSP but has a 7mm hole through it, I believe it's a 3/8" valve body.
The regulator drive spindle was made up from brass, milled to suit the flats on the ball valve and a brass sleeve silver soldered around it. Makes for the neatest fit without any slack.
A pair of blanking plugs for testing the superheaters were made up from the leftovers cut off the bulkhead fittings. Just had enough length, threads and cones were already done, and some 5/8" hex was machined to silver solder to these.
The regulator spindle cover and bush through the smokebox was the next to receive attention. The old Winson one was too rough to use and has no gland.
The hole in the smokebox was filed out and a new cover plate annealed and bent to suit. Next job is to make the bushes and gland.
Happy steaming in the heat! (Or should it be dieseling!?)
