Ah, OK. I need to get the cover off and measure it; I was going by visual memory of a 10-year old event, which apparently distorts things a bit. > If the diameter of the shaft is 8 mm, then the thread is most likely 1.25 > mm. (8x1.25) So at that diameter, the standard pitch is 1.25 then? How big of a shaft before the normal thread pitch goes to 1.5mm, do you know? > I made a tool from a thing they use for tightening steel cables, I am sure > you know it. Ah, a "turnbuckle" they call it here. They sell cheap aluminum ones here, and it's at least possible that they're imported and metric thread. Thanks for the thought. Thanks, Dave Hinz
