Ooooh! Tissue - Glue Putty!

With all the shortages and hoarding of toilet paper, I was reminded about this old Model Rocket construction technique -

This instruction step comes from the old Estes Ranger, K-06.

Tissue/Glue Putty did work well to seal the open areas around the motor mount tubes. I remember using a few squares of toilet paper instead of "facial tissue" for this step.
TIP: While the instruction step says to use "small wads" of tissue, you'll make a smoother mix by tearing the tissue into many tiny pieces.

On my Ranger clone build in 2012, I used a plywood centering ring at the top of the three tube cluster mount.

I still glued on some thick mat board triangles and a little bit of the tissue/glue putty in the center to seal off the top. (I agree - a bit of overkill here!)




Thinking about building a 3 engine cluster Ranger?
The Semroc Ranger kit (now OOP) sold for over $30!
I went cheap - buy a Baby Bertha! The kit BT-60 body tube is 7 1/2" long. Cut that down to 7" (put that on top) and you would only have to add a 11" length of BT-60 for the lower tube.Add two BT-20 tubes for a three engine cluster, make a coupler from a split tube and you are good to go!I
