I found a plug cutter just a mile or two from my house. It was in a tool supply store, but others have said they would have to order it. I've made at least 1000 plugs with it and never have had it sharpened. The air cooler (vortex tube) keeps it cool. I blow the cold air onto the cutter and use a vacuum cleaner wand on the other side of the cutter to draw the cold air over the bit and also suck up the chips. I can cut plugs continuously and still put my hand on the cutter. I use standard supply house pin blocks and since it's too much work to pull the plugs out of the block, I set my drill press so that it cuts only within 1/16 or so of the bottom. Now you can use a table saw or planer to cut off that 1/16 inch and they will all fall out. I've made a pin block drilling machine and I drill out the block a little over 3/8. Can't put a 3/8 plug in a 3/8 hole you know. I've found a metric drill that is just right. Now I drill the plug with a 1/4 inch drill and use 2/0 pins. I'll make it a point to bring pictures of these things to Reno, so if you'll grab me I'll have them in my briefcase. Regarding speed controllers, I don't know of any resistive controllers. Of course they wouldn't work. The reason tools will overheat is that if they have lowered voltage and are loaded heavily, not only will they draw excessive current but will lack cooling since the internal fan is now running slower as well. Speed controllers don't work very well at lower speeds. The reason variable speed drills work pretty well is that it uses servo control. Your finger is part of the servo. Your eyes, ears, and brain are the speed measuring devices. Hence, a closed loop servo.
