Silver Bullet

Silver Bullet

This had the same high-tech wheels as BitMobile, along with highly polished axles (done in drill press). I found the best graphite to be Hob-E-Lube. It’s graphite with Molybdenum, and available at most hobby stores (but is always sold out during pinewood derby season so plan ahead). I found it faster than the white teflon variety but this is endlessly debatable amongst derby-car enthusiasts. Another trick to add to polished axles is to put a small pipe cleaner in a drill motor, coat it plentifully with Hob-E-Lube and run it through the wheel bearing at slow speed for awhile to polish and coat in inside well. Don’t go fast as heat will melt and warp the hole. All these cars have a drilled 3/8″ hole through the body for added weight. I pick up the cylindrical weights from the hobby shop – much better than using toxic lead – and they fit perfectly in the 3/8″ holes.
