Adding Larger Diameter Threads to a Tiny Shaft
I needed to shorten a small shock a bit for use on a Radio Control car. I needed to add 4-40 threads to the end of a 1/16 plain shaft on the shock in order to install the plastic shock end. We mounted a 5/8 inch long 4-40 set screw, which has an Allen head hole already, in a drill chuck installed to the headstock. We used a Cobalt 1/16 drill bit driven by hand to drill 3/16 into the Allen screw using the Allen hole as a pilot hole. This went very well. I then cut the Allen screw ΒΌ inch long and installed it on the shock shaft end with red LocTite. The project came out well and should withstand the rigors of racing this car.
