Is that one of our ( quarry engineering ). Blown Ulster crankcasses as well.

Hi Tony, I think it pre-dates the Quarry Engineering crankcases. It is a new casting but I bought it partially machined in about 2005 along with a new casting 10 stud block, 25 stud head and No5 Cozette - been trying to put it together ever since but keep getting sidetracked with other projects. When do Quarry start making their version?
You are not on your own,I knew of a couple of other similar engines,one took 9 years ,the other 13 years to get running.

Fascinating stuff, Tony! Thank you for explaining.
RE: fantastic but not cheap - Tony Betts - 07-01-2019
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

Hi richard,
I'll say NO.
But I did think perhaps I should until I use it

JonE,
Your next Ulster rep is already on ebay.
Currently £2,700
All you need is a body.
Tony.
RE: fantastic but not cheap - JonE - 09-01-2019
certainly not going to be my next Ulster rep, but I take your point!

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
RE: fantastic but not cheap - Bob Culver - 31-01-2019
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.
RE: fantastic but not cheap - Alan - 31-01-2019
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.
