Default Glider Maintenance - Fuselage Rotisserie

After years of wandering around northern NJ temporarily occupying the workshops and garages of club members who were kind (or stupid) enough to loan out space, Aero Club Albatross (ACA) finally has a shop of our own at Blairstown airport. As the Refinisher in Chief, I'm building out the infrastructure bit by bit to make sure we are well equipped for future projects. I'm looking for good examples of fuselage fixtures, especially ones that allow for the whole fuselage to be rotated at least 90 degrees either way from vertical.

So, does anyone have examples of a fuselage rotisserie with some photos you can share? We already have a cradle/sling as well as solid stands. We also have used a hoist from the ceiling in the past. Each of these presents some challenges when painting, so we're looking to start fresh. Any pics, sketches, or ideas would be appreciated. We have world class fabricators and machinists in our club, so we can go top tier - no 2x4s and bungee cords. You can email me at erik dot h dot mann @ gmail dot com

Default Glider Maintenance - Fuselage Rotisserie

Contact Paul Gaines at alphazulucomposites dot com. At an SSA convention years ago, I saw a "glider roller" he built, and there is a photo showing one at his shop in Kingman, AZ. Not enough detail to build one, but at least a start.

Someone showed some photos of an "octo roller" made from 2 sheets of plywood that picked up front lift pins and rear pins using arms. 8 sided allowed easy rolling to desired position.
I don't remember where I was it. Maybe in the VSA group.
None of these is easy to spray around. For that I hang and tilt 15 degrees or so with a gallon can hung on an arm off lift pins.

Somewhere there is a video of a Belgian repair shop rebuilding a broken
Arcus
They have a rig with 2 steel rings and longerons that pick up on the wing

mounts and Cardinal points.they set it to a second new arcus in it and set
the
points ,then locked it up and fitted the 2 half s of a Brocken arcus to the

same points and re build the bit in the middle
Awesome video if you can find it just build a copy

Default Glider Maintenance - Fuselage Rotisserie

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.
