  It's a Schilling technique and pretty damn brilliant.   I'll end up with a straight accurate crank with hardened bearing surfaces.

Where can one see and read how to do it?
I have his book but it is not very informative how to actually machine parts.

Thank You for the link that made me not the least wiser.
I still do not understand how You get undivided connecting rods on the crankpins.
I want to make a side-by-side two stroke crankshaft with undivided lower conrods.

Thats easy, you have to put the conrods on the Pins before you press the parts together(or whatever conection method you Chose).


On my Bugatti build i have split conrod but the needle bearing are mountet before Pressing the parts together.

Hi Dave,

Been there, seen it, done it, felt the pain

The Mazda four rotor engine was very fast, reliable and incredibly loud, At trackside, the banshee howl far exceeded the threshold of pain. You could follow that howl all the way round the 13 mile, three and a half mnuit lap.

Mazda won the race outright in 1995, the first and only win by a non reciprocating engine. It was also undoubtably the loudest engine ever to have participated there. With the speed and noise came an appetite for fuel. The Mazda's and the Kudzu derivative, needed to pit stop to refuel more frequently than their competitors and gradually lost ground.

Give me a 917 anyday.

It's the roar.....the two cars play a different tune, but it's still sweet music!

I have the BRM V16 as the ringtone on my phone as the sweetest music, the Honda RA271 runs it a close second though :-)
