If you are about to use aluminum tube as wing joiners and need the female tube to install in the wing panel this may help to make life easier and save you a little money.
Get a roll of "GLAD GO BETWEENS" from your super market. It is the very thin plastic sheet you put between layers of meat when you deep freeze meat.
Roll two layers[no more] around the tube tightly and secure with masking tape either end making sure that you have about 3-4 ins longer either end of intended length of tube. Using 6oz f/glass cloth strips wetted out with resin wrap around the GO BETWEEN. About 3-4 layers should be enough. When resin is cured you can then cut of the masking tape and pull out the aluminum tube and there it is. A nice snug fitting tube
I have used this method on all my models.
