Bob, I can't help but feel this question is directed at me, so here goes. I believe that Dale recently gave you an airplane with a carbon tube slider, so you should have something to look at. Since I built the airplane originally, I may be able to fill in the blanks. Check out the crappy sketches. The tube is slotted using an extruded aluminum channel as a guide. The slider itself is based on a 1/32 brass plate soldered into a slotted brass tube. The plywood cheeks protect the lines from dragging across the edge of the thin brass. The release pin hole is drilled on assembly to assure proper alignment. I haven't tried a magnetic slider lock, but I think it would work. It would be clean and totally passive with no moving parts other than the slider itself.
Your slider will be sticking out the front rather than the back, so the actual installation details will be up to you to figure out. On the MO-1, the carbon tube is glued into a 1/2" basswood block which is captured between the spars.
Due to the wing sweep, you may be able to keep the release cable mechanism totally inside the wing. If the high speed position is 1" ahead of the leading edge, you could build the slider with a 1" long "tail" so the release cable would be inside the wing. As long as the low speed position is more than 1" ahead of the TE, the tail end of the slider would not stick out the back of the wing. That's probably as clear as mud, but the short version is that you could probably keep the slider release all internal, and it would reset whenever you put the hook up.
If this doesn't give you enough to go on, feel free to ask more questions. BTW, the new Fury plans look great, and 350 sq. in. should be about right. Don't be afraid to sneak the wing a bit farther forward for CG if necessary.
