wow... so i found my old time zone in the back of the shop that i gave to my friend and he gave it back to me... i had it all plugged up except for the thumb.. so i decided to just tweak it a bit and have the p[in above my ring finger... kick the cg about two inches left (i am a righty) ... and have the mass bias about an inch and a half away from my thumb on the negative side.... and wow... the ball rolls better and hits harder then before when it was drilled before... i mean ive heard stories abouit doing this to other balls from other companies and it workin sometimes but its not reccomended... and now i think im gonna do it to one of my imulses to get a true reading off of it... because it rolls pretty strong down the lane with great rotation... so my impulse is next and if it works well on that... definetly getting annother classic to do it to as well...

The Time zone has a pretty strong mass bias and drilling tweaks that move the mass bias affect it's flip A LOT!

A friend of mine is a no backend bowler and with his mass bias down under thumb on his Time Zone he had more backend than I do and usually it is 2 to 1 me with me having way more than I want! My Time Zone with mass bias on VAL was VERY archy!

REgards,

how do you determine the mass bias on the time zone....(or any balls for that matter)??

thanks bob

mass bias that are strong are marked with a logo of some kind. or a small pin where it was held when the coverstock was poured.

You can find the mass bias on any ball with a core by drawing a line from the pin through the CG. After 6 1/4" you will find the MB area - not exactly, but this is where it is located. Asymmetric balls like the TZ generally have a MB marking. Brunswick uses a small round pin, Storm has the RAD marking on the X-Factor balls, Ebonite had a PSA marker on their balls. But the placement is pretty much the same - even on balls with a symmetric core. The factory marking is just more exact.

By the way: I have a TPC Player with a similar drilling like your TZ: very versatile, PSA at 135Â° from PAP. Strong on medium to oily conditions, great control. A drilling everyone should have in the bag.

There is no point locating the Mass Bias on a ball without a measurable Mass Bias to begin with.

(It is actually 6 3/4, though)

Yes, BN, you are right. The only point in locating the MB on a symmetric ball will be on a pin-out ball (the more, the better), because the mass shift inside of the ball might be strong enough to have significant influence on ball recation upon drilling. Pin-ins do not really matter.

I thought that my putting the MB in a negative position would cause one to flare over the fingers/thumb. Would think that would cause the ball to "jump" down the lane and really hook at all. Might have to try it on a ball as a tester to see if I can get the backend and hit.

What I can tell from my TPC Player is, that the track of th ball spreads differently from a ball with MB of 90Â° or less from PAP. My 15 lbs. Player is a high flare ball (RG diff. 0.068!), and the oil track has 2 intersections - one just next the thumb hole, the other on the opposite side. Normally, you should have the track pattern spreading like a spiral, on high flare balls with larger spaces between the single rotation tracks on the downside of the ball and with less space near the holes.

I have a high track (about 1" from thumb hole), but my tracks do not cross the holes - not more than any other ball I have. The 135Â° drill lets the ball tilt on a different axis than with a less than 90Â° MB placement, I do not think that it affects flare potential. My TPC Player hooks a lot, and it is very controllable on medium to heavy oil.

The tpc player is not a good assymetric to compare to. The mass bias is so weak that even ebonite says you will not notice a difference in moving it around (seriously, I've talked to some of the guys at ebonite).

And pin outs DO NOT make the mass bias stronger! It seems logical, but has been proven false over and over again. Pin outs/cg's in symmetric bowling balls mean nothing except for the sole purpose of keeping a ball legal.
