Two shops that I've worked in use a sling hung from the ceiling. The sling is 2 inch webbing that forms basket under the fuselage. The low tech shop uses a manual block and tackle. The higher tech uses an electric hoist with remote control. The glider is raised up on the sling then lowered down on a sawhorse. The fuselage can be turned to any angle depending on how the tail is supported. For instance, to work on the bottom, you just roll the fuselage onto the cockpit rails and stick a thick foam pad under the top of the vertical stab. For either side, support the vertical stab on a sawhorse.

In fact, I'll be doing exactly this in the coming weekend. In our case, I'll have 4 club members lift the fuselage onto the front sawhorse. Unfortunately, they don't travel well, and we have to feed them.
