Yeah I read about this as well. It was on "the other forum" about a year ago. I read the article and really looked into making one. I never have though due to time and a lack of need at this point.
My idea however was to place this home-made drum sander on the other side of my planer that way when you ran your board through the planer for its final pass, you could use the feeder of the planer to drive the board through the sander at a consistant rate.
I might even put heavy springs on the machine to hold the danding drum down along the top of the board, but I am not convinced that would work so well.
Just some thoughts, though I am not stu!!
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
