I think some people haven't really read the original post well. The problem is not having difficulty pressing the pinion on, it's that the pinion id is the same size as the od of the motor shaft. There is no interference fit. I can easily slide the pinons on and off with my fingers.

Today I acquired a bottle of Loctite 609. I carefully cross drilled and tapped the pinions. I then ground a flat on the motor shaft. Finally I applied the 609 to the shaft and pinions and assembled the two together. We'll load test in a few days when the shooter is finished. I am confident we will be pleased with the results.
