Pinewood Derby BSA Speed Wheels and Speed axles

WHEELS BSA pinewood derby wheels are well designed, but unfortunately the wheels vary considerably from mold to mold. Most of the wheels are not perfectly round and the tread surface is not even. Our Speed Wheels are official BSA wheels which are sorted by mold number, and then precision machined to tight tolerances with a HAAS CNC (computerized) lathe using proprietary fixtures and tooling. The precision of this machining cannot be duplicated on hobby lathes. To provide you with an awesome set of wheels, we perform the following operations: The wheels are sorted by mold number, and any defective wheels are discarded. The wheel tread is lightly lathed to achieve a perfectly round wheel, and a flat tread surface. AXLES Say "Goodbye" to burrs and crimp marks! These BSA Pinewood Derby Speed Axles are precision-made to replicate the official BSA nail, but without the burrs and crimp marks.
