Abstract: An extendable golf club having threadably intercoupled upper and lower shaft sections. The golf club can be extended by threadably coupling one or more spacers between the upper and lower shaft sections and tightening a set screw into engagement with a spacer.

Abstract: A golf club which includes interconnected segments which can be added to extend the length thus providing an inexpensive alternative to buying new golf clubs. The segments are securely connected to achieve a rigid and sturdy golf club which can grow longer as a child grows taller. The segments preferably have a threaded male/female connection with epoxy applied to the threads followed by the added security of a roll pin inserted into the connection.

Abstract: An improved vacuum exposure frame for use in making exposed aluminum printing or lithographic plates permits the use of unworked glass, preferably tempered glass, rather than polycarbonate plexiglass (which is easily scratched) of the prior art replacement of the transparent image-exposure-window material. The frame is routed on the lower aperture-facing portion of the exposure window, preferably by a 90.degree. routing having a horizontal face and a vertical face surrounding and defining the aperture underside. A preferred embodiment has a reverse depression preferably routed out of the horizontal face and a sealant-adhesive is inserted into the reverse depression and along the vertical face so as to secure the unworked glass to the frame. Separate ID windows with long lasting polycarbonate inserts are also in the frame where the main image exposure window aperture is shaped to contain preferably only the book pages to be exposed onto the aluminum plate.
