LOL...Mart, you're absolutely correct! Smaller diameter more load to equate the same torque. I thought about the string thickness and the reduced diameter of the groove area of the spline but didn't think the difference would amount to much. Thanks for the correction...I went the wrong way with the calc...may have been the couple beers and/or the distractions here. Next time I'll think before I type. My pinion now has a firm but free feeling to it and the bearing pack has been mated forever. It's certainly tighter than it was and I have no doubt that it would spin with 30 pounds on it. Now I need to figure out how to recover from the embarrassment of a reversed numerator and denominator in my calc.
