Four more cam boxes on the way.


The pile of parts keeps growing.

The next stage was to make the end plates that carry the front cam bearing.


All four made a light push fit in the cam box



Next reduce the cam box to its finished height, the dimension from the base to cam centreline must be spot on because this affects the cam belt tension.


Three more to do and all the fussy work with the cam followers.

Slowly slowly Brian.

 

[BRIAN]

To bring the cam boxes to size I have changed the tooling to a fly cutter fitted with an indexable
tool from the lathe ,It's doing a great job, speeded up things no end and the finish is good.

Four cam boxes to size awaiting the next operation.

Nice. I like the finish left by the fly cutter. Did you make the holder for your lathe insert?

 

[BRIAN]

Hi Bill . The holder is from an " economy " set I purchased about 8 years ago It's seen more work than I care to think about, still trying to wear out the original tips.

Todays work was to cut the holes for the cam followers .


The next job will be the access holes in the side of the cam box, cylinders No's 1 5 4 have the holes on the right and No's 2 3 on the left looking from the front of the engine.
