Hi Dene A friend of mine has done in the region of 500Hrs on a type IV 2.0 Ltin a Teenie Two, he had a forced landing two years ago, plane was a right off, the prop flange bent but crank still fine, he has nearly completed his replacement Teenie Two,his prop flange was made according to drawings in the manual mentioned,however the material was EN19 condition T, it very close to 4130.
If memory serves me correct a cars clutch exerts a force of about 1700lbs thrust on the thrust bearing, a prop pulls in the region of 200lbs thrust on the thrust bearing.
