I learned something new recently regarding kick back panels. These things deteriorate! My mechanic brought me under a pin spotter recently and showed me this. They are made of a plastic compound and frequently just stapled to the wood. The preferred method is screws which are a special type and it takes 52 of them for each panel.
Screws are preferred because the staples allow just enough movement to accelerate the deterioration where the screws don't. The main cause of the deterioration is the lane oil which gets on the pins and is transferred to the panels. The result is the panels bubble up. The pins hit those bubbles and it creates a cushion instead of a spring like surface making the pins seem rather dead. Other words, bad pin action and the lack of messengers.
The panels come in different grades and prices. Of course the best ones are the most expensive. They deteriorate at a much slower rate and have the best pin action. The price range is from 80 bucks each for the cheapy ones and 340 bucks for the good ones. Obviously you need two per lane. The screws are pricey as well. You can see it's not exactly cheap to have to replace them. The bigger the center the bigger the cost.
Another reason could be dead pins themselves. If they are older than a year and a half then chances are they are dead. Most centers have two sets of pins. One that is in use and another set that is resting in a humidor. After 9 months they should be swapped out to rest and the second set out into play. Once rested they are good to go for another 9 months.
After that they are only good enough as souvenirs or target practice at your local police department. So I thought this was interesting information to share. If you're bowling and notice rather flat and poor pin action, now you have two possible reasons you previously may not have considered.
