very nice work.
looking at your crank pin drawing I would recommend adding a small chamfer around the edge of the pin that makes the initial contact with the hole in the wheel. this helps align the pin to the hole before starting the press fit. it also helps prevent shaving any material off as the pin is being pressed in. I have designed many pressed fitted parts in my over 40 years in engineering. an angle of 15 degrees as measured from the pin centerline seems to work good.
