Band sander

Band sander.

-------
-initially made for 75x533 but different band diameter will fit too. (larger width: NO)

-needs 608 bearings,
-and some M8 screws, one has to be bolt head, at least one that is rougly 80mm long
-a metallic plate should be fixed between the 2 rollers.
-half-roller are screwed together with M4 screws & nuts (roughly 15mm long)

--------
it's not perfect, but the band stay centered once the setup is made.
the torque of the drill machine is enough (I used to resole my climbing shoes)
