[roc-chat] Adhesive - Temperature - Rocket Needed

I'm asked a lot about what adhesives to use for attaching fins.  Most people want to use a high temperature adhesive due to heat transfer from the motor.  This can lead to other problems since most higher temp adhesives have lower toughness and peel strength. When I ask how hot do they think it will get, no one is quite sure.

 

I want to run an experiment, I have some temperature indicating stickers, we use these at work and they are pretty accurate.  I plan to bring some up with me to the lake bed that will show temperatures at 100,150,200,250 degree F.  I'm looking for someone with a bigger project where I can put one of the stickers on the motor case, and one on the body next to a fin to see what the real temperatures are.  The motor case and the body tube should 'bracket the problem'.

 

I have enough stickers to do 3-4 rockets.

 

Anyone volunteer their rocket for the test?

 

Predictions?
