Here's one I have been wanting to do for awhile. Bought a dust deputy and the instructions states to drill a couple of holes in the vacuum and bolt the dust deputy and the vacuum together with a chintzy foam block sandwiched between them. Didn't really think much of that idea. There were two vacuum attachment points that were unused. I turned, yes even this was a lathe project, two cylinders and then drilled 1.375 holes in them, that fit snugly over the attachment points. Cut the platform from plywood attached the cylinders added a swivel wheel. Works great no more tippy dust deputy and didn't have to alter the vac.
