I have 2-styles of pinions in my inventory. Press-fit and solder. I can already solder a pinion on a motor shaft so fast, very little heat runs into the motor. But I prefer not to solder pinions on short motor shafts like flat-6's, etc.

It may be possible to invent an extention to add to my pinion press to get past the axle supports.

Thank you kindly for the input. Please keep it coming. No one has a monopoly on good ideas.
