Aggressive ! I need to keep those delicate fingers of the G man away from this wheel.I have been using a Eastwind 60 grit sanding wheel since I discovered they offered them and loved it because it made things quicker which means less time on the wheels and less stress on my worn out hands. This wheel is not made to replace hard wheels but it allows you to fudge a bit and it is beyond quick.The Eastwind 60 is well broken in and spins beads pretty well but Eastwinds are a smother wheel than nova wheels in any case.This nova is a knuckle deformer, very sharp and when working next to it you can be bleeding from inadvertent contact and not even know it.I have been using this shop a year now and having experienced a winter in it I feel comfortable in moving my most used machine , the Titan , into it.The walls are just dead air space as the walls on the inside are sheathed with plywood and there is no insulation other than the dead air space.A very small heater maintained the temps inside at just below 50F even when it was ten outside for a few days in a row last winter.At zero who knows.I like cold so 50 is fine for me if I use hot water in the drip through system. Nova hubs are now 1/4 inch wider which screwed up my drip system. I am moving more plants in for the winter as I am confident in the building and have an automatic propane generator for when our power goes out which it does quite often on this wind tortured sand dune. Spinning beads on a new sanding wheels is a waste of time but I had to try it. You can see in one picture that I am holding the bead on an axle parallel to the wheel face and it is bouncing. I have holders that hold the bead on both sides to stabilize it when really working but this wheel is far too rough and bouncy for that to work. When it is broken in perfectly for spinning beads it will never be used for anything else and a new 60 will be put on a machine in the other shop for general shaping.Have fun cutting.
