"Could someone point me to a dimensioned drawing of a turntable that includes the tower? I've searched my archives, and though I know I have seen a drawing somewhere, I can't seem to find it. What I'm looking for are the dimensions for the tower as I wish to scratch build one."
Should be on the Internet, here and there.
A friend of mine has a Bowser turntable; never could "get it to work", as he said, though the specific maladies I don't know.
This seems to me a hole in our O-scale product mix - a moderately-priced, long enough for big articulateds, reliable, basic turntable. The high-end items are beautiful, but not everyone wants or can buy a $1500 turntable. The Atlas is good, I understand, but it's only 24" (my Lionel SP 2-8-8-4 AC-9 is 32" or so in wheelbase) and is goofy-looking - the "pit" moves!
If Atlas would offer both a 24" and a 36" (or so) version with a better visual (fine-scale not required), reliable, for under $500 - I'm there. I'd even replace my 32" scratch-built one (it works, looks good, but it's...not suave).
