Ball drilling gradient scale help
« on: October 31, 2011, 12:22:27 AM »
 I have a question concerning the angles. Should the secondary angle be larger or smaller to increase hook potential for heavier oil. I ask because l just had a ball drilled and my driller said it should be smaller but I am not seeing what I was hoping for from the ball.  The baill is drooled 50x30x4 1/2 but its not nearly as strong is I thought it would be.
  It's a mission x,and I tested it against a vg drilled 60x65x4 1/2 an.d the vga is a good five board stronger

Go to the MoRich website and find the Dual Angle Layout instructions.  The first part is how to lay a ball out, skip it and scroll down to the section near the end that tells how to apply dual angle layouts.  The information you need is all in there.  Then find the Gradient Line Balance Hole instructions and it will tell you how to use a balance hole to increase reaction (remember to keep the ball statically legal).  Remember, though, surface preparation affects ball reaction more than the layout does.  --  JohnP

thank you John. I looked it up and if I am understanding the smaller the secondary angle in relation to the val angle the earlier the ball should roll,so my fifty by 30 drill should be stronger than a 60 by 65,now i want to redrill the vg,darn it am I ever gonna get this right,lol.

Yes to the lower angle sums to being more hook. But did you take into account that maybe the Virtual Gravity is just more ball? Also, what surfaces do you have each at? Have you used the Mission X on some pretty high volume? Maybe it is burning up. Just a few things to consider.

Honestly I would never have considered the vg to be more ball,based on these facts,the vg is a second drill,ball that I bought used and have no idea how many games are on it,with newer technology I would have hoped that a newer fresher take on the subject would have warranted it be better than the old,and I do have a stronger drill angle on the mission x.

    That being said,i have thrown the mission x on three seperate occassions and as I dont know what the patterns were, my basis for comparison is on present balls in my arsenal and their response to the conditions.

    First time out was just after a 3 man league. It turned out to be a short set up and not nearly enough oil for the ball I couldnt keep it right of the pocket no matter what I tried.

    Next time out was on a fresh ths 38 ft with oob passed 7. I dont know why ,but the lanes played differentlyone lane was about 5 boards tighter this lane I had to play right up 7 and as long as i watched my speed and angle it got to the pocket,but carry was a major issue.  Nice pocket hits,but i left more single pins in 3 games that I have left in a while. The other lane ,when I got lined up, the ball reacted well and carry was nice,I had miss room in and out. This is the shot I compared using the vg. Where the mission wouldnt recover or carry the vg would.I had a good 3 to 5 boards more area with the vg and had to play deeper.

 

   My next time out with it was on a shorter pattern and once again not enough oil,the ball grabbed at my feet. It would work from a deep line ,but it labored to get down the drier lane. I ended up having a great look with an omg and my rising star. Both got thru the heads much better so it made for an easier stroke to the pocket. Now dont get me wrong it is a good ball I was just hoping it would be something I could go to when the vg wouldnt let me play where I wanted,but the vg is still the strongest ball in my bag. The mission x is a close second.

If the val angle is higher than the drill angle the ball will hook earlier and have a slower response to friction, more of the rainbow shape! The val angle lower than the drill angle the ball will go longer and have a higher response to friction, more of the hockey stick shape!! Hope this helps!


Train a child up in the way they should go and when they are old they will do some "Damn Good Bowling", be a "DV8" and not turn from it, besides bowling starts with a Big B!
