Hi fly,

I've had a bit of problems with that hub. The set screw is Loc-Tie and had to use reverse drill bit to get it out. Then, I had to snug it just so you can slide it up to the top of the flat spot. Then (and I shouldn't have), used Loc-Tite again, thinking it would not loosen up. Well it did and now I need to destroy the hub to get it off. Luckily, I have 2 or 3 on hand. I know this is an old thread but I'm trying to get to the bottom of these issues so MAYBE Exceed will get it together alittle more and put out a little better machine.
