Batter Up Build Part 5 Locking Rings
I cut a 1/4" length of ST-7. This was glued over the back end of the extended BT-20.
This locked the tube onto the handle of the bat.
An engine block was pushed into place with an engine casing.
The engine will extend 1/4" out the back, beyond the ring just glued in place. There is no engine lock clip, a single external wrap of masking tape will hold the engine in place.
Another ST-7 ring was glued over the 1/8" of BT-20 sticking out the top end of the bat. This locked the internal tube in place at the top.
While the Estes kit ejected just the ball at apogee, I used a streamer tied to a length of Kevlar.
