L3 build - Fin Lamination


Lets reinforce some fins! I got to thinking about what was really necessary for an M3 flight and I decided that 2 layers would work fine, just to save on weight and carbon. After all, I'm doing 3 layers of T2T anyway. It'll be fine. I used a foodsaver for the vacuum bagging. This is my first time with a foodsaver, and I've got to admit I'm pretty happy with it. It's about as simple as it gets. 

Here's the process:

Fin was prepped with a pass of 120 grit and acetone.
Here are the fins, the +-45 layers, the Peel Ply and the 90 layers
Here we go! 
Foodsavers make really easy work of vacuum bagging small stuff. They don't pull the strongest vacuum, but for 2 layers it shouldn't really matter all that much. 
Fin Removed from Bagging

Here are 3/4 fins I did. I wonder where that 4th one went...

They turned out alright. Onto attachment!
