A proper sized drill is a must when tapping holes. Machinist's manuals always have tap and drill charts and older versions of these books are easy to find cheaply. Also, be sure to use a lubricant and if it becomes difficult to turn, back the tap out to clear the chips before trying to go any further. Note: If tapping cast iron, no lubricant should be used. (JerryVan, if I'm wrong about cast iron, please correct me. You know way more about this than I, but that's what I was taught over 50 years ago.)

Right or wrong, I tapped lots of cast iron using a cutting oil when I was a machinist. Cast iron will dull your taps quicker than mild steel.

I have a harbor freight 7" "precision mini lathe" and I bet that it would be a super easy job to true the friction disk.

I have two portable machines, one a Japanese "Columbia" and the other a Japanese "Nova". Both had warped friction discs, in brass. I took them to a colleague who skimmed them in his lathe. It took about ten minutes, problem solved.

Out of curiosity, has anyone thought of/tried using an acrylic disk instead of a metal disk for this? Acrylic circles of all diameters, thicknesses, hole sizes, colors, etc., are widely available for peanuts.
