Need advice on a turntable for my son

Actually for a Floor layout Atlas is about the only one you can use.  The entire turntable is designed to sit on top of the platform so it could sit on top of a floor.  Most higher end tables have to be mounted from underneath (search for Millhouse Studios on the web)the platform to make it level with the track because a real turntable has a pit.  Don't think you want a hole in your floor haha.  Atlas has put the motor and gearing in the little shed on the one side.  Although its one of the cheapest and least realistic ones out there I have heard its pretty good as far as operation from some posts on here.  So probably would be you best choice for a floor layout.  Not sure about carpet as you have to keep the track level with the turntable track.  You may have to cut a piece of thin plywood or something so you can screw it down and screw down the ends of the tracks coming up to it.

RE: Atlas Turntable Operation, Good / Bad?

Rich, here is some information on the Atlas 6910 you might want to read. It was a previous post. There are a lot of posts about this subject for you to read.

For a floor layout  & tabletops an Atlas TT is fine. If money is a consideration, you can buy new or used for cheap money.  There are some nice hi rail layouts that use an Atlas turntable. I believe the Atlas is modeled after a turntable CA, I don't know the exact prototype.
