I'm pretty sure this doesn't break da rules, but I suppose if the thread is gone and my account banned tomorrow I'll know why .
The turntable in question will be 8-10' diameter, will have a total weight (including scenery) of about 600lbs, and should be capable of a 180° turn in about five seconds. According to my calculations, I need 2.68HP, so ultimately a 3HP motor to accommodate drive losses. Does that sound about right based on others experiences?
If you're interested in the nitty gritty (read: nerdy) details, the turntable and supported scenery have a total mass moment of inertia of 4671 slug-ft² and the motor should be able to accelerate all of it to 6rpm in 2.5s.
For the final drive I'm leaning toward roller chain wrapped around the circumference of the table.
