I am in the process of making quite a few end grain cutting boards. I recently acquired a drum sander and sanding out the grooves left by that is really annoying. Needless to say I am now in the market for a sander that will cut down some time on this process. I am thinking about the Rotex 150 or the ETS EC 150. I am thinking that the Rotex could be overkill for what I need but if it will save me a decent amount of time I will get it. Does anyone have any experience sanding end grain that can chime in?
