Thats a good possibility too, as the mill is working. They also has a bastard buttress thread based taperlock work alike that I might be able to use. Properly snugged up to 1/8 turn from broke, I would not need any keyways either. I'll dig into that case later tonight too. IIRC I looked but no 9mm hubs in that style so I backed out. But they also need more free shaft length that I have too from the pix. The 10mm hub for the upper one has about 11.5mm of available shaft, but that hub needs 15 or more IIRC. The lower, flanged pulleys problem is its a 9mm shaft. To use one of those assemblies I'd first have to make a 1/2mm thick spacer tube. Or, I have more tool steel shafting, and that shaft nose could grow to 12mm without an huge amount of trouble once I make this work temporarily. I did get it to track decent today, but its still too high, so I'll put a foam weather strip in to hold it up for clearance, need about 1/8". Redrilling the screw holes isn't a problem. But I didn't get quite that far before I ran out of me today as I was thinking and running a hand backhoe too, trying to fill in the gas line ditch in the back yard that leads to the standby generator. Should have done more of it yesterday when this stuff we mistakenly call dirt was a bit softer. By tomorrow it will be as hard as granite. Yellow clay, grows weeds & nut rock real well but nothing edible. :( Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
