A friend of mine gave me his cherry bomb to see if I could rescue it from the deathbed.
It had upwards of 300 games and 500 probably would not be out of the question. It had lost alot of reaction, hit light, and never carried anything. It was basically a xxxl.
I have restored several balls, including an old Norm Duke Hammer that went from a 10 pin ball to one of the biggest hooking balls I own in a matter of hours. I have also restored my cherry bomb using the following methods.
First think I did was put his ball in the oven, at 140 degrees (the lowest my oven will set too). After about 30 seconds the ball was soaked in lane oil. I continued this for several rounds, each time taking out an inordinate amount of oil. This took several hours, removing the ball every five minutes. The coverstock never got warm to the touch and core was still cool.
I put the ball in the dishwasher(heated dry off) and went to bed. The next day after work, I was curious if I there was still any oil left in the ball, so I set it back in the oven, and it bled for the next 2 hours. I would stick my finger into the thumb hole to feel the core temperature, and it never got hot, or really warm. Finally the ball only bled on the track side, then the track area, then it was clean. I'm sure there was a small amount of oil left in the ball, but I refused to leave the ball in the oven long enough for it to get the core even warm. After all it wasn't my ball, and I'm not into taking chances.
Then the ball was dry sanded with 400 grit to remove the track, wet sanded with 400 grit, wet sanded with 800 grit, and finally 1000 grit. Then I hand polished the ball with turtle wax compound and followed it with 3m's scrath remover polish. Both a pure polishes and completely silicon free. I polished the ball to a high high luster.
After about 6 hours of work, his ball is still not reacting the way it did when it was new. I heard he has a couple of boards back. If the coverstock has been bled and refinished, I don't understand why the ball would not get its reaction back?
My cherry bomb now hooks like a beast and acts brand new. Same with the Norm Duke hammer I re did, which also had close to 600 games when I took it over.
Any suggestions or ideas?
