I needed to clearance the nose cone for the gliders, and I installed the 3/16" dia. screw eye for the Kevlar shock chord.

SSA: Weight Check
I weighed the components, thus far, and made a 2.3 ounce adjustment in the Open Rocket simulation.

SSA: Glider Retention: Nose Cone
These are the dowels that engage into the glider nose cones. The dowels are 1/4" dia. and the aero bits are made from basswood.

SSA: Ramjet Closures and Lower Glider Retainers
I turned a couple of discs on the lathe to cover the end openings of the ramjet tubes.
I bored a 1" dia. hole in the one disc to allow stowage of an altimeter. The lower glider retainers glued to the bottom of the BT/C-300 & lower centering ring.

SSA: Motor Mount Centering Rings... and a Display Stand
I used a 1-1/4" dia. Forstner bit and a 2" hole saw to cut a couple centering rings. Then chucked them in the lathe and cut the o.d. down to slip fit into the C-60 stuffer tube.
The motor retainer hook is made from a piece of stainless, salvaged from a discarded wiper blade. I also made a display stand for the rocket.

Thanks. Plastic straw is the Kevlar conduit... then inserted the motor mount into the C-60 stuffer tube and started the gluing process.
