The propellor flange is mounted on a taper on the end of the crankshaft. While the tool was set over for the crank, I took the opportunity to turn a bit of silver steel to use as the reamer for the flange.
I hardened the thing out and then just polished the edge with a whetstone.
The flange was just a turning job although getting the tapered hole in the back square to the front face was fun. In the end I machined the front first and then pushed it hard against the chuck while I step-drilled it, reamed it and cut the keyway.
It all worked well and I could push it onto the end of the crank. Now I can turn it and I must say that I am very pleased with the outcome. It it smooth and slightly tight with newness rather than binding. A good outcome.
Now, onto the pistons. I decided to do them in pairs, crown to crown.
After doing one end, I reversed the piece and held the new piston in the collet chuck while I turned the other end.
Here is a new purchase in the shape of a collet chuck with a base that can be held in the vice. This is my first use of it and I must say that it made life easy.
Two pairs of pistons ready to part off.
