DRESSING THE WHEEL. okay, so i just received my Blackstone X02 yesterday (can't hide my excitement).... im horrible at manual tasks in general but so far everything seems pretty straightforward. im just wondering something concerning the process of "dressing the wheel". from what i understand, this is the process of shaping the grinding wheel using the spinner. i.e., while the grinding wheel is in full rotating motion, you slowly move the little spinner towards it so that they touch each other which results in the spinner giving its shape to the wheel. in the video on the X02 on their site, it seems like you have to let the spinner touch the grinding wheel for a about 3 or 4 seconds (which creates some dirt coming out of the little exaust) then you move the spinner back and you're ready to sharpen the skates. is there anything else to know about dressing the wheel? is it always that easy? how exactly does it have to be done? and am i in the right ball park when i say 3 or 4 seconds? also, it might seem a bit stupid but im wondering, do I need to dress the wheel every pair of skate? or every single skate? or do I have to do it only rarely, like when im starting to use a brand new wheel or a new type of spinner? thanks in advance, i have yet to try this FBV thing on real ice, but i can't wait!
