In my shop, we have two rollover rings:
* An octagon made from two plies of hardware-store 2x4s, where the plies overlap at the joints. I also made a roller stand for it, but we mostly just set one of the eight edges down on the floor.
* An infinigon (my daughter's term) we made out of a 48" diameter welded steel hoop salvaged from an abandoned kid-sized trampoline. We use it with the roller stand I originally made for the octagon.
In both cases the hoop attaches to the forward lift pin fitting, which by definition can carry several times the non-lifting weight in pretty much any direction. There is also a strut that attaches the hoop to one of the two aft lift pins to prevent the hoop from rotating around the axis of the forward lift pin fittings.
For the aft fuselage we generally just rest the tailboom on a padded sawhorse just forward of the vertical fin. We also have a sawhorse with two rubber wheels for this duty as well. For a finished glider, we girth the tailboom with masking tape where the roller runs so it doesn't scuff the paint.
There are photos in the HP-24 facebook page albums, probably back around October 2015 when we were painting 24-03.
Thanks, Bob K.

The nice thing about the octo version is that it takes up very little space when it is not being used. If you are in a big shop and move stuff around a lot, a roller stand is a nice addition. Most of us find that space is the most valuable resource in the shop and storing big stuff you don't use very often is not a good use of that space.
I use a simple stand with a curved upper face that nests the fuselage. The curved upper face is 2 pieces of 2 inch pink foam mounted vertically in a box on the top of the stand. If I need a special contour is is cheap to make from the foam and the foam does not scratch stuff. It allows me to rotate about 120 degrees either side of vertical which allows access to almost everything I need to do. I can position without help. With that and an electric hoist I can do everything I need to do without needing help.
P3 is familiar with my cheap ass solution.
FWIW
