Just a tip: adding one or two extra keyframes at the start and end of your turntable animation (exactly one frame from your start and end keyframes) can keep the turn rate consistent and alleviate the odd acceleration and deceleration at the start and end of your animation. Some programs allow you to edit this accel/decel as a curve or in params- but the keyframe method works for pretty much everything i've encountered.

Nice model though :3
