I needed a way to drill a 3/8″ to 1/2″ diameter hole in 2″ thick rigid foam. Traditional drill bits wander too much and leave a terribly ragged hole. So do spade bits. A hole saw works great, but the smallest I could find was 3/4″. So… I tried a Grain Belt Models 36″ HO-scale culvert. I think the results speak for themselves!
Hi…I’m looking for a N scale DCC trolly “to & fro” system with 3 intermediate stops. What do I need to accomplish that?
