    So a couple of months ago I ordered the Skybolt fuselage tubing kit from Spruce. They've been telling me some of it was on back order every couple of weeks. Today I got a call asking how I would like it cut.

    Does anybody have preprepared list I could use?

    I'd just have it shipped in raw form (20' lengths or whatever) -- you'll need to have steel cutting capability if you're going to build the fuselage, and you're going to be far more careful with your cuts than they will. It would truly suck to get the tubes in and realize they misread your instructions or set the intern to the job, and cut some of them 1/4" too short or something. If you get the tubes pre-cut you also don't get any of the offcuts lying around, which can be useful material in and of itself.

    Get the longest lengths you can. ACS throws it in a box, burrs on the ends of tubes, doesn't pack it or tape the tubing together and sends it to you with little or no packing.


    If it arrives without scratches and gouges, go buy a lottery ticket. My experiences were mostly shipped from Georgia. California was a little better, but not much.


    Good Luck

    Have you looked in the Skybolt newsletters yet? I’m sure it’s listed in there somewhere.

    I agree with getting full lengths. If you can, start by making the longest tubes first, then when you screw one end up, it just becomes the next shorter tube, minimal waste that way.

    Thanks everyone, After talking to them again they said they knew what to do. I eventually received two boxes. One 20 feet long, and one 24 feet long. It was shipped to my work, and I used our box truck to bring it home.

    On another note, splicing the longerons, the forward tube is 7/8 x .035 and the rear tube is 3/4 x .035. there seems to be a lot of gap between the two sizes. Is this what everyone has used?

    I have the impression that the joint between those two has a long fishmouth (like 3-4x the diameter of the tube it's cut into), and may be tapered down by judicious use of a hammer, press, or similar tool, possibly involving some heat. This is based on observations I've made of completed fuselages, not any work I've done myself, so take it with a sizable lump of salt. ;)

    Hundreds of Skybolts flying with that splice. I would avoid straying from a proven design.

    I went with the plans. Tacking one side then working the larger tube down w heat.
