I currently do not have a drum sander and using a ridgid 13" planer. When I make end grain cutting boards of different thicknesses of woods, I find sanding them flat to be a pain. My belt sander skills are either lacking or it's very difficult to flatten with a belt sander.
My dad suggested an straight line sander like below, they are used in the auto industry. They are 2" x 17" roughly and seems like it would flatten a board pretty good. Any thoughts on this?
It's a pain for me to head to the cabinet shop and wait several days for $40 to flatten a board. I hope so soon find a used drum sander or get my 16" old powermatic running and try planing end grain with it, carefully of course with sacrificial runners etc.
I have a couple hand planes too but need to perfect my skills in the that. The current board I made is about 1.5" thick but wavy in spots. I can put little rubber feet on it and no one would know but I'd rather avoid the feet and square the board up.
