BUILDING THE SIMPLEX PETROL ENGINE
Part 5 by Phil Procter
Next the rockers.
I started with a couple of discs.
Ball ended slot drill was used to make the pocket for the pushrod bucket.
Picking up the centre line with a laser centre finder.
A bit more shaping by milling out the undersides.
Almost there, just a bit more fine tuning with the file before fitting the ends.
Ball turning tool set up for making the pushrod buckets, I used silver steel for those. (drill rod).
A bit closer in.
After silver soldering all the bits together.
A trial assembly.
All the other bits finished and assembled on the head.
