tight on space... my workshop is a 11.5' by 20' carriage house, with 4 or 5 motorcycles in there at any given time, sometimes a Model A project, misc. little projects, etc...
... given that tight space, i gotta make things compact and multi purpose.
belt sander / bandsaw combination:
it's just a pipe welded to an old rim... super stable, free and easily movable.
welded a mounting plate for the belt sander that came from a garage sale ($5)
another mounting plate for the tote-saw that came from a garage sale ($6)
big ass 1/2 hp motor that came from a garage sale ($10)
put a switch in a j-box (leftover free stuff)
$21 later i've got a damn serious sander and a bandsaw that's awesome for small/detail work (and no off-the-shelf blades are made for it so i've gotta buy in bulk and cut/weld them)
and not a tool, not really home made... but found some cool shelf brackets and a 2x4, mounted a top box up on the wall out of the way:
