To attach a pinion gear or a gear to a shaft or axle in model building, you can use a technique called press-fitting.

Another method is to use set screws, which are small screws that can be tightened against the shaft to hold the gear in place. Additionally, you can use adhesive such as epoxy or super glue to bond the gear to the shaft or axle. Make sure to align the gear properly before attaching it to ensure smooth operation in your model. **
