I've managed to throw out a few superfluous items --- excluding the furnace --- in my basement room where my layout is installed. So, I now have an additional approx. 5' X 3' area into which I would like to fit a turntable and roundhouse, plus perhaps sidings to park stuff I am tired of looking at on a shelf. I am looking for basic turntable mechanism material and roundhouse plans with which I could scratchbuild.
Would any of you experts out there have suggestions ?
I know there are wonderful ready to use S turntables on the market, but I would like to keep the cost as low as possible and enjoy building myself.
