hello,

could someone tell me in easy words how to measure the axis tilt?
is it right?

a big axis tilt makes the ball go longer? is the ball more like a helicopter style?

thanx a lot

0Âº axis tilt is a full roller, 90Âº the ball would be spinning. The only way i know of to measure the axis tilt is to look at your track, if you track close or on the fingers and middle you have a low axis tilt, and if you track far away, you have quite a bit.

Where the track is has no bearing on your tilt measurment.

Tilt is determined by the size of your track circumfrence. 0* (full roller) is a full 27" track, a 90* tilt (helicopter spinner) you can fit the track under a half-dollar.

You can either measure the circumfrence with a tape or by measuring the tracks "diameter" through the negative axis point. Measurements are of the initial release track only (tilt will change as the ball flares).

When done in this manner, a 1" change in "diameter" equals a change in tilt by 6.67*.

Balls thrown with more tilt will react later to surface conditions.

That's the best way and most scientific.

Another way is to put a piece of white tape on PAP.

Axis tilt can be estimated this way. If tape is level to lane and parallel then you have a tilt of near 0(yes will have the large diameter track referenced above).

If tape points towards ceiling you have maximum axis tilt and the small diameter track above.

I have been told that ideal for today's conditions is in the 17 degree area.
I unfortunately am stuck near 12 my ball wants to read quickly except I also have 65 degrees of axis rotation.

REgards,

PS by looking at where tape points in relation to you can also determine axis rotation. Back at ya = 90 degree. To the lane left of you for a righty = 0 degree axis rotation. Half at ya and half at lane to left = 45 degree axis rotation. Easy!
