So I have an beautiful OOP Estes Vagabond (the Mid Power one from the early 2010s), but had some crushed body tubes when I opened it.
Instead of trying to build it as a mid-power flier, I decided she needs to be a minimum diameter 38mm machbuster... I hit up ole Soller Composites for a CF/FG weave sock and wrapped the body tube
... but in a moment of genius, I thought to 3D print out an internal liner/stiffener that would provide some friction for the RDS Id like to use and keep the BT in full roundness for the glassing operation.
Pulled out my brand new flashforge 5m 3d printer and made myself the part as described. Stuffed it up the backside and liberally applied some JBweld to hold it in place.
So, after about 3 weeks of having this amazing machine, I learn that there are different filaments... and they have different mechanical properties including the temperature ranges where they fail... and THEN I remembered that rocket motors get hot... like VERY HOT... like TOO HOT TO TOUCH after lying in a field for 20 minutes while you hike to collect it hot.
Now I am VERY concerned about regular ole PLA being used as essentially a motor-mount tube on a 38mm "I" motor.
This leaves me in dire need of feedback dear forums... Is my project totally screwed? If its ok on the heat.. GREAT! If its NOT ok on the heat.. is there ANYTHING anyone can imagine I can do about getting it OUT of my body tube?
