I've covered building the spools in another Instructable, so here I will focus on the rack that I designed for tabletop use.
-2 10"x24"x1/2" boards (I used some scrap plywood lying around; I can't help but think that this would've looked better in oak)
-1 10"x22"x1/2" board (to act as a shelf)
-1 2"x22"x1/2" piece of lumber (I used pine; this is a horizontal strut for stability)
-1 1"x28" wooden dowel (we had an old broom handle laying around that cleaned up nicely)
-Bandsaw (if you have a thin enough blade, you might be able to get away with using a handheld scroll saw)
-Belt Sander (you could certainly hand sand these, if you have no life and eternal patience)
-90 degree angle clamps (these are a lifesaver. I used the makerspace's, but I now plan on getting my own)
-Powerdrill, drill bits, screws.
-Compass (the circle-drawing kind, not the superstitious "magnetic" ones)
-A 1 1/4" hole-saw (not essential...it just made things a little easier)
