Today, in addition to working on the crosstubes, I made this tool for my vise out of some scrap angle iron so I can smoothly "smoosh" the end of tubing destined to be in the tail feathers. There are a few places in the tail where the sizes are quite a bit different and need to be resized to fit. I got the idea from a DVD I bought about 4130 fuselage construction from Jump Run Enterprises. I really recommend the DVD
