If I were designing a pressed crank to be built at home I would have press fit dowel pins for exact alignment,....to be removed after the assembly is pressed together. It would have full bearings on soft shafts and needle bearing rollers on hardened shafting for the rod...... This is extra operations in the production environment so it is not done that way. They do not even have alignment marks because those are extra operations. Every extra operation costs more money.

. But, if you're using most of the Parts that have been already machined and hardened.
that works too. if you have the parts or can get them.
