My first model :D Help/tips plz

Ok so i just got blender and am playing around and i want to remake the Turnstile from d1_transtation_01 because i always thought it looked crappy. And after animate it to work with the player to replace the old brush work in the map. So let me know how i should go about it and how to scale it to the player .mdl (its the easiest one i could come up with that i want to do and it only will use a few cylinders).

Thanks,
Alex

I suppose you could just use a citizen model as a reference, they are about as big

Also don’t animate the model, just have 2 separate models: the frame and the rotating part itself, since it’s physics based.
