I put these together a few months ago and thought some one else might benefit from the idea. Supplies needed: scrap pieces of 3/4" wood and two female trap adapters (used under a kitchen or bathroom sink). The plastic-nut end of the adapter is 1.25" and works perfectly because it is built to be tightened and loosened by hand and because the Mutoh scroller (or media holder rod) is 1.25". The other end of the adapter is 1.5". Any good hardware store will have these and cost about $2.50 each. The outside piece of wood should be around 5" in diameter. The inside piece of wood (which goes inside the core) should be exactly 3" in diameter. I used a belt sander and tapered this inside piece a little toward the inside, because some cores are a bit less than 3" in diameter. I used a circle cutter and a floor drill press to cut the wood into circles. You can also do this with a router, but you would have to make a template out of some thinner wood first. For a few bucks, most any cabinet shop can make them for you. I put everything together with Shoe Goo adhesive. Before you comment on the aesthetics, I know these are not pretty. I did say scrap wood. They work like a lucky charm. Not that I'm cheap or anything, but I just couldn't see paying $200 plus for a pair of plastic flanges from Mutoh.
