Pin Distances...?!
« on: March 13, 2006, 03:07:37 PM »
I'm looking at getting another ball for medium - dry lane conditions... and I just got my Lane 1 Tsunami drilled! However, I'm looking into a Cobalt Bomb and saw a few for sale with different pin distances... can anyone tell me if theres a huge difference say between a 1-2" and 3-4" pin? My tsunami has a 4" I believe.

Thanks!

Someone PLEASE correct me if I am wrong.

A ball with a 1-2" pin compared to a 3-4" would tend to get into its roll earlier then a ball with a 3-4" pin. 3-4" pin balls are great for that big backend skid/flip reaction. (Asymetric balls will react differently as their Mass Bias are all slightly different from each other, my response is for Symetric balls)

i have a cobalt that is drilled 4 x4..goes long but moves on the backend..needs some dry boards..my ball speed needs backing off, and when i play with a softer hand, the ball comes back hard...if you ball speed is high like mine, 18 mph, you can play a more down and in shot...hope this helps j

As I understand it smaller pin to cg distances limit the drilling options as there are fewer ways to lay out the ball while still keeping it legal (I.E.  It's pretty tough to put the pin anywhere above the fingers cuz then the cg is just an inch or less from your fingers)

As a result most short pin-cg distance have to be drilled with the pin somewhere under the fingers and the cg fairly close to mid-grip.  People with shorter spans can get away with shorter distances, and a good driller can make some adjustment but you can expect some weightholes or insanely deeply drilled fingers and or thumbs.

Yeah. You know, I had a guy in Jackson county. He had a little drum circle in his backyard. It turned into a drum circle four miles in diameter. You get a few hippies playing drums and next thing you know, you got yourself a colony.

Generally, pin-ins will react a tad smoother than pin-outs. Additionally, pin_daddy is correct since pin distance limits drilling options when the ball is to be legal. Therefore, pin-ins are mostly used for pin under ring layouts, for layouts that roll earlier. Pin-outs have a higher mass bias due to the core/CG shift. The impact might not be big, but I think pin distance choice is an important thing when you layout a ball and chose the specimen to punch up. You can emphasize the ball's and drillings characteristics with the pin distance choice, but that's IMHO all about it, plus the legal aspect.
