Construction is complete except for the motor retainer. There are two items of note.
I decided to make a cord protector from a scrap of car air bag material. I covered about 5 inches of the Kevlar leader with a couple of wraps, swabbed on some 5-minute epoxy, and compressed it while the glue set. We'll see how it holds up
I often talk about how saving spare parts, scraps, and even random junk pays off. And, it did again. I drilled the holes for the rail buttons using a drill guide (a new product under development by Dog House Rocketry - more on this when it is formally announced). The holes are just above each of the two lower centering rings. I stacked two buttons to give the clearance for the larger payload section but found they were too wobbly. I poked around and saw a piece of 1/2" thick basswood sticking out of one of the bins on my workbench. It already had two holes drilled in it, so I must had previously thought about using it as a standoff. The big coincidence is that the two hole lined up perfectly with the holes that I had drilled in the body tube. Amazing!
