I like to experiment and try new things with everything I do. Today's experiment just happens to be extending one of my tennis racquets. A question some tennis experts might ask is: Why would you want to extend your racquet? You will lose maneuverability and quickness. One of my hypotheses is that keeping swing-weight to a minimum while adding weight to the handle can help maintain racquet control. Many extended racquets in the past, because of the weight of material composition, have had very high swing-weight. Many extended racquets in the past have been far to head heavy and light weight, which would add to a less stable feel. Yesterday, a friend of mine let me use one of his least favorite racquets (Wilson K Fierce FX 105) to start my experiment. For fun I attached an aluminum pole to the end of it adding 5 inches in length and 2 ounces in weight. This was a perfect racquet to start my experiment with because it had a swingweight of 295 and only weighed 10.3 ounces. Beginning weight was 10.3 ounces and 6 inches of aluminum pipe (2 ounces) = 12.3 ounces and ended up 14pts headlight (I think swingweight/ and low end weight are more important factors). Beginning length was 27.25 and end length was 32 inches. I knew that control would be an issue because the racquet handle was now round instead of hexagonal. I wanted to try service speed. One of our university police officers clocked my serves with my Prince 03 racket all in MPH (108, 113, 116, 99, 111). After 20 practice serves with the Wilson K frankenracquet I was clocked at (130, 118, 133, 122, 112). Surprisingly I was able to get 3 of the 5 serves in! I realized that, over time, a person using an extended racquet would slow down arm speed to compensate to add control and would eventually serve about the same speed. I've heard many racquet professionals say that the length would not add speed. I believe that hypothesis to be incorrect.

The next part of my experiment is to actually modify an old racquet I have laying around Hyperhammer 3.6 with rollers. When I first tried this racquet it was out of control and I just plain hated the lightweight, headheavy, and oversized head (115). In order for me to modify it to my liking I added 1.5 ounces of lead to the handle (end weight, 11.6 oz 8pt hl) and used a tight hybrid string set up (Cyperflash 58lbs mains, Forten Nylon 60lbs Crosses). I really tried my best to be unbiased, but I was blown away by the performance of the racquet. Certainly it took several minutes to adapt to the added power, but after I did it felt great. So now I am in the final process of added modifications to my new Frankenracquet. I will be adding an 1 1/4 inches to the Hammer 3.6.

I will drill holes in the bondo to bring the racquet to the desired weight.
