Would y'all mind posting pictures of your rigs? I'll be needing to build one here soon. Need some ideas
Not sure this will do you much good as my setup is pretty unique due to the hardware I salvaged. I did find a couple photos that may show what I did.
First photo was when I was painting the Skylark. It shows the Camera Tripod I was using with an insert of the mount I made. The heart of the mount is a fitting off a studio flash the is normally used to mount the flash to a stand. It is a cast chunk of aluminum with a 1/2 inch hole and thumb screw to tighten it on the stand. I made a plate out of 1/8 inch aluminum that bolts to the flash mount then bolts to the motor mounts in the airplane. I had a bunch of the flash mounts from modifying flashes for my ride photo systems.
2nd and 3rd photos were when I painted 3 FJ-4-15's all at the same time. I made mounts for all 3 using the Flash mounts and somewhere along the way I switched over from the tripod to the A frame shown. Joe Gilbert gave me the A frame, believe it was a jig he used when he was building his home built full scale. Worked great as a paint stand.
I also have mounts bolted to one of my benches, one vertical and one horizontal. I can leave the flash mount in the airplane and move it to the bench to mask, sand or install control surfaces and position it any way that makes whatever I'm doing easiest. 4th photo shows my Latency mounted on the bench when I was covering the fuselage with carbon.
