Spring pin for the win. In house thicknessing returns which beats a 45 minute walk each way to the hobby collective down the road. Pray it lasts until I can upgrade…
Thanks for the tips!

Salutations. The spring pin that holds the gear to the elevating shaft of my drum sander has snapped, allowing the shaft to spin freely in the gear rendering it useless. I have managed to remove the remnants of the old pin from both shaft and gear and have a clear pathway to knock in a new spring pin and resurrect my drum sander. My question is, is there some specific benefit from having a hollow spring pin vs a solid core rod such as say the back end of a drill bit? Is there some machinist wisdom I should know about? I’ve found suitable spring pins online and can buy them, but they come in bags of 100 which is 99 more than I need. Any downside to just using a drill bit or some other type of hardened steel rod? |

The roll pin is slightly larger in dia than the hole. So when it is tapped in the compression of the roll holds it in place. It is a very effective fastener for the purpose. Any hardware store or big box builders supply would have a selection. I'd replace it in kind. |

Stick with roll pin unless you plan on penning the solid pin. Otherwise it may work itself out due to the vibration of the machine. And even then I would stick with a roll pin… |
