Mike Wooldridge Medium hard single layer leather tip suitable for snooker. Hard leather is pressed and the fibres are compressed accordingly. For the production of a pool cue tip, [vegetable-tanned leather]] is used.
The tip is glued to the cue and the overhang is turned on a lathe, rounded in the front and sanded with the finest abrasive paper so that the tip ends flush with the ferrule. Finally, the leather is treated with a sealing on the outer edges. When playing pool, billiards or snooker, the tip is repetitively chalked to avoid slipping on the ball.
Any leather can be used though I prefer oak tanned cowhide. The LD is warmed to about F. Just prior to the molding operation, the Moca is melted and heated to F. The leather flour is mixed in and the resulting mixture is poured into a compression mold having the shape of the tip desired, the mold being preheated to about F.
The mixture is allowed to set in the open mold for about two to four minutes and the mold is then closed and placed in a heated press for about 30 minutes at F. The molded cue tip is then removed from the mold nad cured in an oven for about 18 hours at to F.
Prior to use it is desirable to slightly toughen the rounded head por tion of the cue tip as by rubbing with a fine emery paper.
Rubber, Vibrathane series can be used with equal results as a replacement for LD-l This can be accomplished by filling the shank portiton of the mold with the pure resin and then filling the head portion of the mold with the aforedescribed mixture of the resin and leather flour.
The polyurethane-leather composition is at least equal in performance, and is superior in durability and other characteristics, to the best leathers including elephant hide and cowhide. While it is exceptionally excellent as a cue tip, it will be understood that it will have other utilities particularly in applications where the frictional characterstics or other qualites of the best grades of leather are desired, for example tips for womens shoe heels. Cue sticks provided with one tips made in accordance with the invention have been tested by a cross-section of billiard players including experts and have been found superior to the most expensive cue tips heretofore used.
This is, of course, the ultimate test as regards the frictional and other characteristics which are important in accomplishing the desired impact and English on a billiard ball when it is hit.
The durability of the cue tips of this invention exceeds that of the best leather cue tips for one reason because they do not tend to flatten or otherwise become distorted from use.
Also, they are tough, have no tendency to split or tear and are not damaged by moisture. When replacement is necessary due to wear after a long period of use, it is simple and inexpensive without need for adhesive bonding and setting.
Other synthetic elastomeric organic resins can be used in place of polyurethane to form the mixture for the cue tip, but not with equal results.
It will be understood that while the invention has been described in detail with reference to a preferred embodiment thereof, various changes and modifications may be made all within the full and intended scope of the claims which follow.
Referring to Figures 1 and 2, the end portion of cue stick 1 is cut to provide an inner dowel 2 of less diameter than the end of stick 1, and an outer dowel 3 which is concentric with, and of less diameter than,. USA en. ESA1 en.
