Abstract
Abstract A demountable fishing rod is formed as a single tapering tube with a thick walled central portion, the tube is cut in two at the large end of the thick walled central portion to form a butt portion and a tip portion, the thick walled central portion is sized to receive a cylindrical sleeve which is glued over the sized portion to extend rearwardly beyond the tip portion, the tapering small end of the butt portion is sized and coated with a mold release agent, the sleeve has a molding material inserted therein, and the tapered end of the butt is held in the sleeve while the molding material hardens to provide a demountable joint.

Claim 1
Independent Claim
144 words
The method of fabricating a demountable rod comprising the steps of: a. forming a tapered fiberglass tube having a thickened central portion with an outwardly thickened wall; b. cutting the tube in two at the large end of the thickened portion forming a tapered butt portion and a tip portion having the thickened portion at its large end; c. providing a cylindrical sleeve; d. sizing the large end of the thickened portion to receive the sleeve thereover; e. fixing the sleeve on the sized end of the thickened portion with the sleeve projecting rearwardly therefrom; f. coating the small end of the butt portion with a release agent; g. placing a molding material in the sleeve; and h. inserting the small end of the butt portion in the projecting end of the sleeve and allowing the molding material to harden forming a demountable joint.
