Fracture (Our first splice)
Over the past couple of days we have had a small rest from the making of the launcher, and have focused on making a spliced pair to add to our fleet. This has given us an understanding of the manufacturing technique, and will also allow us to compare the 3.8l splice to its closest current rival Nexus I which is a 4l Robinson coupled pair, and have a full understanding of the advantages and dis-advantages between the two manufacturing methods.
We used Titebond polyurethane glue mixed with Polyfilla and Sikaflex 11FC, as is used by other hobbyists, the polyurethane glue and Polyfilla mixes can be found here (http://www.aircommandrockets.com/day46.htm#diag_visetest)
The sleeve was made from a shrunken 3l bottle.
FRACTURE I fully assembled it stands at 102 cm.
