I modded an older Kato/Atlas Century chassis so I wouldn't have to pry the weights off, clean them, than glue the weights back down every time I have to have it apart for maitenence. I wasn't really looking foward for drilling metal through with a pin vise, and using my full-sized drill would be bulky. I had an idea to make a home-made mini-drill though.
Home-made mini drill: I Took a spare athearn motor, took off one of the flywheels and attached my double ended pin vise to the bare shaft. then I stuck my drill bits in the other end. Not nearly as fast as a drill, but better than pin vise my a mile. I used an older DC powerpack for control. It was kind of tricky to use whole holding the pieces in place, but it worked and I had good control of the speed.
In other news I turned 21 on Friday. It kind of stunk since all of the things I planned to do got cancled by something or other. Haven't had any beer yet.
