Re: Johnson A-80 flywheel puller bolt size?

[Mumbles]

On the early motors, Johnson used 14-24 machine screws to hold the rope sheaves on. With a major diameter of 0.242", they are slightly smaller than 1/4" and larger than a #12 machine screw. Since this size was pretty much obsolete before most of us were born, you won’t find them at your corner hardware store today. Taps and dyes of this size are available from specialty tool suppliers but if you don’t want to spend the coin, it might be time to gear up the old lathe to make the screws and and cut the thread.
