My Rehabbed No. 85 Here are the pics of my newly rehabbed drill nicely done by LONE PINE TOOLWORKS. Before thrust bearing. Before Someone used pliers on the chuck. Here she is all restored. The bolt (thrust bearing) at the top helps to guide the wheel. Here’s a closer look at the thrust bearing. And a look at how the thrust bearing guides the wheel. http://lonepinetoolworks.com/index.html
