Big Girtha Build Part 19, Odds and Ends
Normally a baffle like this would be used to couple two body tubes together. I had to install this one from the top.
The fit was tight so I didn't feel good about putting glue into the tube first then having it "freeze" in the wrong spot.
It was dry slid into the tube using the end of my straightedge.
Figuring space for the parachute and nose cone shoulder I felt it needed to be 8 1//2" from the top.
Fillets were applied using a long dowel with rounded ends.
The shock cord anchor was made up "Centuri" style using a piece of scrap body tube.
This mount fits the inside curvature of the body tube better than a tri-fold mount could.
This style of mount won't work in body tubes smaller than a BT-55 size.
It might block the parachute ejection.
From the front end you can see the shock cord mount set down 2" from the top.
Below that is the installed and filleted baffle.
The picture makes the baffle look like it is five feet down the tube!
I've got a little paint to clean up on the inside of the body tube.
