RE: Turbo Plugs How To
Andy Thanks for This!! Here`s just an observation..see the pic ..Maybe the Rpms of the lathe,opposed to the Drill press,For useing the Center drill,is an issue?Possibley ,the amount of cutting edges, on the Simple phillips bit, is keeping the Taper ,to the hole ,more Square.If you have a dial indicator,Check your drill press Spindle, is not wobbling.It really makes no sense ,if the Center drill is the correct cutting angle,You should end up, with a leak free seat..I know the cheapest ,easiest method, is with the Screw Tip.Sure is a strange thing though.Could there have been, tooling marks, in the glow plugs` taper ,causing a leak?The thing is ,why would the Center Drill work in the lathe ,but ,not the Drill press??Very odd.
