Here is the finished rocket. The bumpy black body doesn't look this bad in the flesh although I do need to wipe off some finger prints/balsa dust. I ended up cutting a cardstock ring to seal the top of the six 24mm tubes that ring the central mount. I will likely fly this on a single motor and I wouldn't want the ejection charge escaping out the back. I just don't think I want to invest 7 motors in this rocket...for now. Plus I'd need to add more nose weight for a 'full load'.
