Sorry in advance for all the newbie questions that I'm likely gonna send today. Had lots of shop time yesterday which got me thinking about some stuff. How much time do you spend hand sanding? I spent about an hour per blade yesterday and after 3 blades I had enough. I'm just using the hardware store gator paper from 3M (I think). It seems to take forever to get all the grinder marks out with 80 grit before I go on to finer. I was only going to a satin 320 finish. I am sure that a better grinder with finer belts would help a lot. I went to 180 on my 4x36 which is all I have to work with but is there something I can do to speed this up? Any advice would be appreciated.
