+xMy opinions:
-You really should have made the mounting section separately. This would have been one of the easiest projects you can think of.
-to get the cloth in wrinkle free (assuming one fibre direction is along the length of the part) start with the middle line, and then work your way outward in parallel lines, in soft strokes starting form the centre in both directions. You can either use 0° or 90° as your starting line.
You used spray adhesive during the bagging? To seal the bag? That's what the gum tape is for. to protect the bag from edges and screwheads most people use breather cloth. Ec has a video about an airbox, where they bag a 3 part mould. That's basically how it should be done.

The mounting section is not my biggest problem in the moment.
And: the mounting section is already part of the mold.
I fill it with a mixture of chopped carbon fibre strands and resin.
That works well so far.
I also have no problems with wrinkles because I can make the visible layer with some side-cuts and overlay in a not visible section of the part.
So I don't have to cut my weave in 45° degree angle (what would end in a lot of waste).
I did not use the spray to seal the bag.
I sealed the cutted edges of the bag with the gum tape.
After the bag was still leaking I tried to fix the problem with pray on the outside of the bag.
To use breather cloth for the protection of the bag is a very good idea. Thank you for that.
I know the airbox-video from ec. They use prepreg in it.
During the next days i am going to clean the mould and make another try with protected edges and screwheads and perhaps a well sealed bag.
I will post it here...
