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.
