Run your Drill Press in Reverse

In making my pieces for Harmony VAWT I needed to find a quick and efficient way to run my cheap 110v drill press with a capacitor start motor, in reverse! I have a LOT of parts to tap and needed accurate rigid tapping. This is using a Centaur tapping unit. They cost about 150 dollars on e-bay and work well but you need a REVERSING drill press or milling machine to use them properly. Just a simple 110v wall switch switch in series with 1 of the legs on the start capacitor and a bit of technique. POOF super clean easy solution to my problem. I am NOT responsible for you blowing up your motor because you don't understand electronics or electromagnetic principals!    • Full History of Harmony Turbines
