I’m not officially starting a build yet but as I’m wanting to try out a new vacuum bagging technique on another project, I decided to try the new idea out on a main foil. I have based the dimensions of the foil on those proposed in the "Optimum wing " thread. I have uploaded a full set of .STL’s and also the Fusion 360 file to Thingiverse so that others can modify the model. My plan is to vacuum bag the PLA printed core with a few layers of CF. As I state in my Thingiverse text, this wing is completely untested
My vacuum bagging will be fairly conventional except that I will be using an 0.2mm silicone film mounted in a frame as the vacuum bag. I’m confident this will mean I can skip the peel ply and most of the synthetic wadding used in most vacuum bagging setups. The silicone should stretch and most importantly, not stick to the epoxy. The foil will be my guinea pig as it’s relatively small and simple in shape.
I will keep you updated on my progress in this thread.
BTW, I am located in NSW Australia for those of you who are curious.
