If you have Overland locos you have encountered the pesky plastic driveshafts slipping on the motor and tower shafts. I wanted to make them bulletproof.
The fix is pretty straightforward but is pretty time consuming. Doing this fix on a center tower diesel means making 6 of them! I have been doing this fix for many years now but a more powerful lathe purchase this past spring made it easier. I can drill much larger holes with one pass. Previous incarnations was soldering 0-80 nuts to a thin brass tube. I could not put much pressure on the screws before it failed. I now start with 5/16 solid round brass stock and drill to a snug fit on the original plastic Overland parts and tap 2) 0-80 holes directly opposite of each other. As you can see the remaining material is pretty thick. You can really crank the screws with a lot of pressure on the shafts. I have at times cut flat spots on the motor & tower shafts.

The solution has not hit me yet. I know if all parts were brass it would be noisy.
