A friend of mine built a gun out of douglas fir and glassed it .From what he told me the fiber glass was to stiff and did not give any when the gun expanded and contracted so it delaminated.If your thinking of using oil for your gun you will have to go with teak wood and use teak/tung oil.I'm not really sure about the properties of oak for spearguns but there are different types of oak.I had some red oak and thought about using it but the open grain made me change my mind.Happy building
