Interesting - thanks.

re #1 - were you referring to losing the hexes, or the wobble? it's mostly the latter I find surprising, really

re #3 - what drives me nuts is that I'm supposed to know about conical gears pretty well... my 8th scaler is usually looked at best-in-class in terms of freewheeling at my track, it will spin forever. Current shimming is 3+3 on both sides, and the backlash is "just right", less shimming to free it up will mean too much slop.

Will check #4 - then again I have no pins left once the build is done now

Thanks - feel free to comment anyone???
