With the aid of a spring winder, the springs were made.
I turned up the spring retainers plus a few spares.
Then it was on to the rocker shaft mounting pillars. First job was to turn up the pillars.
Then to make a start on the cross pieces. Holes first!
A couple of plugs in the end to give me a filing datum and then I radiused the edge with the file. Right or wrong, at least they will all be the same!
Cut them off and face to length.
The tricky bit was to silver solder them together with the tops pointing the right way so that they do up tight in the right position. I scribed the top of each pillar before fluxing and assembling. Then I rotated the top according to the line and soldered them up. They seem to be OK.
Clean up and onto the next.
The rocker shafts seemed like a good place to continue so, as they are only grooved bits of silver steel, I have just done them. The datum was taken from each groove from the last in order to keep the tool close to the chuck. This does give me tolerance stacking but I don't think it will be an issue that I can't get around with the rockers.
It is beginning to look quite pretty. Timing gears next.
