while doing a frame up on my 63 i bought a rotissiry after finishing under body and removing it , i am piece painting car. I tried to figure out how to paint door's and then install them without handling too much and avoid chance of scratching them . got the idea to mount each one to each end of roto. using angle iron bolted to door , used existing hole's on door's and using house door hinge's and drill hole's as needed . My roto has hydraulic jack's on each end, and can go up or down and tilt horizontally, i can prop door for vertical alignment by propping between upright of roto and inner door. the 2 by 4 's are to prop up the door's to lay flat when painting by lifting door up and installing the t board's i don't have to remove door's from roto till door is bolted to car. I also drilled 2 0ne eighth inch hole's in each upper and lower hinge's before removing door's from car when i first removed them, that will take a lot of guess work out of bolting door's simply by installing bit's into hole's and tighten bolt's. Maybe somebody has done this already, but i thought i would share my idea.
