For those that have been reading this forum for a time you might remember a posting i did regarding a 1914 Peugeot racing car that we were doing and the problems i was having with the valve seats and combustion chambers.
The work involved lots of trips to the welder and lots of cutting to remove piles of weld in the hope of saving the block of a very significant car.
Well after lots of time and work the owner decided on a backup plan.
Now we are still going to finish the original block, but since this car is intended to be driven on tours and some vintage events a unit with higher confidence that could be used without fear of another failure was deemed a good idea.
The original block was sent to England where a company that does lots of F1 work was commissioned to do new patterns in order to make a new block.
Last week a box arrived and inside was my latest job.................
Fun part here is there are no drawings just the old and rather abused block.
Have to locate and machine all features on this thing and let the foundry know if it is good enough...they will make an additional 2 for spares if this casting proofs.
Not crazy about making lots of iron dust, stuff gets everywhere....but i do like the challenge...got to make it right the first time so everything fits and works as it should. Lots of hanging dimensions...such as locating the valve guied bores....angled and positioned so the bores form a line that converges with the opposite side at a point in space.
Stay tuned for more.........................
Cheers Ross
