Thanks IAN,
Gerry, dave passed away 6 years ago. So I would guess he started doing them 20 years ago.
The pump could be from either dave flake or PAUL bonewell. I only had one batch from dave, because paul was to busy.

Hi Tony,
Do you Have a Display Case to go with the Hadley Crank and Rods,?
It has to have a Mirrored back.!!!!!
Has anybody set up an Engineering Art Galley Yet.
The oil pump does look like the Quarry Engineering one to me.
Cheers Richard

I had news today that my 1:5 inch Phoenix pressure feed crankshaft is cracked, near the back is this normal.
So my problem is were do I get a new replacement crankshaft. I am in NZ

What is history? Has it been subject to extreme rpm? Has it been dropped on end, cracking the nitride layer? Perhaps before delivery.
Has it been reground, removing the nitride layer?
I presume the nitriding is the main reason for Phoenix reliability but the process is not majic. Stresses go up with the square of revs and 10% stress increase has a huge effect on fatigue life.
It is odd that cranks fail at th rear where bridge bending is supposedly least. I guess the flywheel acts as a rigid anchor. Torque is reckoned not very significant.

I’ve known a few to break. Usually after a hard life or an unsuitable regrind i.e.not enough radius in the corners. I don’t think torque is particularly significant either Bob, but I blame a lot on dynamic imbalance of the flywheel.
