TitleAxle Drilling Advanced Tip
CategoryBuilding the Vehicle
Commentto improve axle alignment avoid drilling into the wood grains which can deflect the tiny bit. Begin with an uncut block. Widen and deepen the existing slots to about 1/4" square with a saw. Fill them with JB Weld epoxy, sand smooth. Using drill press, high rpm and #44 bit(0.086" dia) drill axle holes. Be careful to layout the hole centers with precision, prick the center to start the bit. Maintain the original wheel base spacing. Once holes are drilled you can recut the slot using a bandsaw very carefully. The epoxy will drill a much straighter and consistant hole than natural wood.
