the larger part of Centrals’ business these days, rather thanthe high-priced brass sales of times past. The newer 3-Railscale stuff has shined a lot of light on O <strong>Scale</strong>, especially withaffordability. We think there’s still a niche for Central.Best to you and yours!Lou Houlemarde, Central Lo<strong>com</strong>otive Works, PO Box401231, Hesperia CA 92340clw2000@earthlink.netA Different TurnI loved the article about constructing the turntable (OST#29). It’s filled with good ideas. The only thing I question is themethod of transferring power to the turntable. Here are twoalternatives which I think are easier to build and more reliable:(1) Cut short pieces of copper water pipe and glue themonto the wooden dowel (for insulation). Arrange wipers tocarry current to the turntable. For a third circuit for lights, justadd one or two more pieces of copper pipe.(2) Go to Radio Shack and get the following parts: #274-0893 Adapter, $5. This has a male stereo plug on one endand two female mono jacks on the other. #042-2548, Y-cable,$6. This has a female stereo jack on one end and two 15-inchcables with male mono plugs at the other. Plug the stereoplug into the stereo jack and the two mono plugs into the twomono jacks, forming a loop. Cut the two cables anywhere inthe loop. Voila!! You now have a rotating electrical union withthree conductors. This is sufficient to provide track power andlighting to the turntable, if you use a <strong>com</strong>mon bus or <strong>com</strong>monrail system.Neither of these methods provides for reversing the polaritywhen the turntable rotates, but I don’t consider that necessary.I prefer to use a separate reversing toggle switch for the turntable.I would use a momentary-contact switch with a springreturnto “off” or “open” to operate the turntable. I would alsouse a momentary switch for each stall track. I think this wouldbe easier to operate and far easier to build and wire. It’s foolproof;you can’t leave the wrong stall track “on”.Ed Miller, Broomfield, CO.uMar/Apr ’07 - O <strong>Scale</strong> <strong>Trains</strong> • 39
