Ah yes, sanding – the most romantic part of boat building. Initially I tried to conquer surfaces using sheet orbital sander… One may get the results faster using a bit elbow grease… Then I found nice discounted Makita eccentric orbital sander, without bells and whistles, just button for on/off. Works like a charm, for the record.
Im pretty tightwad concerning buying various fancy tools one may or may not need, but I tell you that, its pretty nice to hold in hand such a tool that minimizes the possibility to mess up and nullify whole work you previously have achieved 😉
