So I have been sharpening now for a year and a half professionally using a work sharp, edge pro, and cotton buffing wheel attached to a dryer motor. My work sharp seized and thought this would be a great time to step up my game as it is just too slow to make money to support myself and family. What I would like to do is go door to door and be able to sharpen out of the back of my van. I was looking at some Dc to AC converters to be able to run anything I may need. (if any one has had any that worked great please say.) Now money is tight so I'm wondering is it feasible to do this with a harbor freight 1x32 and a harbor freight 3/4 hp 8 in bench grinder (mods necessarily? I know the platform is shit but what else?) , some array of belts and some paper and leather wheels. would you need any thing else door to door?
