(...) Okay, I will start. I'm in need of examples of GOOD/GREAT and functional turntables. We'll worry about a roundhouse later. I've knitted together hundreds (400+) 8x8 plates and placed them on 4 large baseplates. So I have the ultimate (...) (17 years ago, 17-Jan-08, to lugnet.trains, FTX)

(...) I don't have any pics off-hand, but the best designs I've seen use a circle of 9volt track for the base of the turntable, and a 9volt motor set under the spinning track. Come to think of it, the power functions motor and plastic track would be (...) (17 years ago, 17-Jan-08, to lugnet.trains, FTX)

(...) Likewise, if you can get a hold of 4 curved monorail tracks, I've seen that used as the basis for a turntable also. The smooth top of the tracks makes a good running surface for any sort of motor-driven wheel. -Jordan (17 years ago, 17-Jan-08, to lugnet.trains, FTX)

(...) I don't have any pictures, since I had to dismantle it when I moved, but I had pretty good luck using a technic turntable, driven by a worm gear. The span consisted of four pieces of straight track, built up with some plates and tiles to make (...) (17 years ago, 17-Jan-08, to lugnet.trains, FTX)

(...) Using train track would make a huge turntable. The monorail is a more practical size (but would cost more) As a matter of interest how big do turntables get in the US? Are/were there ones long enough turn a Big Boy? Tim (...) (17 years ago, 18-Jan-08, to lugnet.trains, FTX)

(...) I have no shortage of monorail track, so I'd like to use the monorail for the circle. It lends itself for a nice 20" (4 straights) diameter circle. Figuring out how to build the "bridge" (what's the technical term, trainheads?) isn't an issue. (...) (17 years ago, 18-Jan-08, to lugnet.trains, FTX)

(...) The Pennsylvania RR engine terminal in (URL) Crestline OH.> had a 110 ft. turntable. This was just big enough to turn most of the Pennsy's largest steamers (probably with some overhang). The PRR had an even larger 125 ft. turntable installed (...) (17 years ago, 18-Jan-08, to lugnet.trains, FTX)

(...) Nah. "Huge" is such a relative term;-) (...) UP had a few turntables that could turn Big Boys; otherwise they would just use wyes. Not sure about modern one, though. JOHN (17 years ago, 23-Jan-08, to lugnet.trains, FTX)
