Well, I revisited this Pedal pictured above & now I'm Happy with the modified Knobs.
I was going for the Silvertone 1484 style knob
I Drilled and Tapped a new thread above existing thread & put my Stainless 1/4'' shaft with Knob in my drill.
I cracked one so this one pictured is how they started out.
Cut it 12mm from the top of knob while spinning with my Hacksaw.
Put the now New Knob on the 1/4'' shaft in the drill & smoothed the Knob with some 1200 grit wet & dry.
Yes it's my own Eyelet Board Design in reference to the Picture posted above.
