Airsoft M72 LAW rocket launcher

Step 4: Preparing the fiberglass

Most people work with fiberglass matt for small projects because it is very cheap. However, I find using fiberglass cloth is much easier as we are working with a small diameter curve and cloth is more flexible. Cloth also gives a smoother finish.

Buy Cloth tape 10-12 inches wide by 2 yards long. Cut up the cloth to wrap the tube with 2-3 layers.

I had a choice between polyester resin and epoxy resin. I went with general purpose epoxy as it has no odor and does not shrink as it cures.

It is fiberglasss cloth tape used to make the outer tube.

Yup, i found it easier and cheaper to by really wide fg tape than it was to buy a yard of fg cloth. Less cutting and shaping involved and I don't end up with too much material that I dont need. Why buy a square yard of fb cloth when all I really need is a piece 2 ft x 1 ft. Plus fg tape has better edges.

I too have found the tape to be cheaper.

skip the fiberglass and build my other launcher. Or use carbon fiber.
