I didn't actually build this just hold a nose cone, well ya I guess, but it was just so I had something to stabilize the nose cone so I could drill a hole through the tip area and epoxy a wood dowel. I had some card stock laying around so I said hey why not. I'm going build one for my Jayhawk kit when it arrives for the same reason, to epoxy the wood dowels and mount the canard fins. Took about an hour. Pictured 4" Patriot nose cone.
