c11 weight reduction

Hello all. I'm new to the list so sorry if this has been covered. I have an orange-tube c11 on an oak tripod my father-in-law made. The scope and tripod must weigh 150 pounds together and it's difficult just to move from the back to the front of my deck.
Question: Has anyone seriously looked into significantly reducing the weight of the tube and fork? I mean, drilling, cutting, filing, disassembly, etc. with the goal of maximum weight reduction. Anybody know a source for a carbon fiber tube of the proper dimension?
Thanks,

Hi Paul,

Late reply, but no one else jumped in. I had a C11 orange tube with the fork mount for a while, and the tube dismounts from the fork rather easily, but with an allen wrench required. There are 2 1/4x20 by 5/8" long socket head set screws in the "saddle plates" that connect the tube to the forks. If you point the tube upwards, and remove those 4 screws, the tube can be lifted straight up. The first time you do this, have help, when I got mine, the stops in the tube were not installed (you can't see them until you slide the tube forward) The stops are shorter socket head set screws which slide into channels on the inner side of the saddle plates aligning the holes for the mounting screws, and preventing the tube from sliding too far aft. Once you get the hang of this it is quite easy, and doesn't require butchering up the tube or mount. Heaviest pieces are in the 30 pound range whn broken down like that. The real caution is to not use screws longer than 5/8" to mount the tube to the saddles, as they will hit the mirror, so if you need extras, order a box of 50 from mcmaster.com. Good luck!
