I need a way to use 1/8" dia. straight shank cutters in a Gorton pantograph engraver with a taper socket spindle. A ready made collet is very expensive to buy new, so I was considering trying to make one from drill rod. The problem is that oddball Gorton spindle taper. Is there any simple, accurate way to set up to turn this without all the trial and error? Is it even reasonable to attempt to do this without some sort of precision grinding equipment? I'm not sure what the spindle speeds are since the data plate with the information is missing and they couldn't help at Gorton, other than to tell me the machine (a 3-F) has not been made since the 1950's, but it takes almost a full minute for it to come up to full speed and so I'm guessing it could be somewhere around 15,000 rpm or more. Any advice appreciated. Mike
