For tailboom I took a countour copier from hardware store and made replica of underside of boom at the support location. I then test fitted cardboard template from that. I used the cardboard to draw a cutout on multiple squares of plywood. Ended up with about a 3 inch thick “U” of plywood that I then throughbolted some 2x4 legs. I lined the “U” with some foam rubber doormat. I made the whole set up short enough that I could put a hydraulic jack underneath it. Made two of these, one for each boom. Jacked them up with the plane.there was some running around from jack to jack. Did have to put some blocks underneath due to not enough reach of the jacks, so be ready for that.
The plane will try to tilt backwards as you raise the underwing jacks. I use the bogert jack adapters on the spar jackpoint screw hole at the wing. And yes there is jack point ball on belly behind nosegear.
