No, I'm not really in need of a drum sander, yet, but I just saw this and kind of when "Hmmm"
When I see a new way of doings the same old job, I take a long look at it, often, the reason why nearly every large surface sander, like the wide belt one you have is very similar, because through years of use, trial and error, the best design or the best use of the basic principles get worked out, and become somewhat set in place.
When something new pops along, I like to take a look, as sometimes it is someone thinking in a new direction that can change the way we do stuff.
I'm sure the two man handsaw lumber jacks all thought the idea of a chainsaw was just plain pie in the sky nuts, and I'll bet the first chainsaws were fairly lame
If you know what I mean.
Some of the things the guy says in the demo make sense, at first look anyways.
I was just interested in this different way.
