how do you drill an offset Asym?
« on: November 12, 2006, 02:57:27 PM »
I asked this question in the drilling forum and they pointed me to come here and post it saying that there were some real knowledgable people in this forum about this subject,  now here it is.

I have a friend that got a Track Xception from a closeout deal a while ago. well this ball has probably the worst pin/cg/MB line I think I have ever seen. Its a 1 inch pin, and it is literally in a "T" to the mass bias. basically its like this

P CG


MB

We tried a drill with the MB on left side of thumb and it just did not roll well at all for him. (fairly low rev, slow ball speed, high track, stroker).
I have heard of layouts where you draw a line 13.5" from the MB through the Pin and then use the spot you end up with as the MB??? Not sure if that would work or not as I'm not exactly a pro on Asyms. basically if I can do this then I would lay it out something like pin next to ring with the CG kicked towards the Midline and then have the Opposite MB mark around 3-4 inches away from his PAP. Anyway, just wondering if this would be a legal drilling and how it would work, the pros, the cons, etc. I'm hear to learn so go ahead and teach me.

Thanks,
Jeremy

Ignore the Cg in the layout process.  Pick a drill using Pin and MB distances, and drill the ball.  Drill the fingers 2 1/2" deep to remove some of the excess finger weight.  Then weigh the ball, and place a weight hole accordingly.  Remember, CG DOES NOT MATTER IN BALL REACTION!!

yeah, I realize that you just don't worry about the CG, in asym balls, but if I were to lay it out the way I would like to, I'm going to have so much finger and side weight that I'm not sure I could drill a X-hole big enough to get them down under 1 oz.  On top of that if I were to lay it out like that then the placement of the weight hole would more than likely be in a place where the track would flare over it.

HEY JEREMY!

Check out this pic of my Mean Machine...
http://putfile.com/pic.php?pic=main/8/22313550658.jpg&s=f10

When I first pulled it out of the box, I was like 'Oh crap! How is this going to work?' I put it on the determinator and the MB checked out right. I was so worried about where the CG was. However, I just decided to lay it out Pin Below the Ring Finger and put the MB around the 5 o'clock quadrant where this placement gives me the strongest possible help. This ball flat out hooks, so don't worry about layout. I also had 2 Rule Delta 1's with the same exact type of pin placement you show in your post. No problems here! I say go with whatever your buddy wants as far as layouts or whatever you think he needs best. I also had an X-Ception with the MB left of thumb, and you said your buddy was a stroker...well I'm a tweener and the ball went completely straight! Had it plugged and redrilled with the MB around the 5 o'clock area and three months later had my third 300 and first 800 series with the X-Ception! Hope this helps some buddy! God Bless You and have a great week!

when you are right handed and you have that placement of the pin, cg and mb it does make it hard to get that ball to have the mb on the right hand side of the ball and still have the ball legal. It is able to do but a little harder then normal. Yet most people see the way mikes MM was and think O man that blows, but I think that makes it easier because then you can kick the mb out to the strong position you want and not have to worry about weight hole. Only thing is that mikes was a little more then what I am talking about, [url]http://www.putfile.com/pic.php?img=3136544[\url] now that is a more ideal look as to what I mean about how the mb being right of inline can be a good thing. But if it is left of inline for a righty it gets a little tricky to drill but stil able to do, but you will look at having to use a weight hole. If I had that ball I dont know if anyone els would put this layout on it, but I would go with pin and cg on my val and then I would try to place the mb close to my thumb to maybe try to get it to retain some backend reaction. Yet the side weight may be really high and hard to remove.

I believe the ball he is trying to describe looks something like my Rule Delta 1:  http://www.putfile.com/pic.php?img=3965338

Hey Tyler!

One thing I noticed about your RD1 is that its a x-out. Funny thing is..my RD1 had that exact same line up of Pin, CG, MB and it was a 'first', it had no 'x out' on it at all. Hmm...weird! God Bless You and have a great week!

Like SteveAustin said,

Put it on the scale(determinator) to find out the mass bias is at the right location, every pro shop should have one if not then go find one that has it. Then drill the way he wanted. Good luck.

Pin positions affect flare, and flare affects friction, and then friction affects ball reaction.

Mike yours is pretty much the complete opposite of what he is refering it.  I know Jeremy as well as the person that he is refering to.  The ball is layed out kinda like this.

----------
-----p----
------cg--
----------
----------
-MB-------

I'll try to take a pic of the ball tuesday or wednesday if the bowler in referrence has the ball with him and post it here so everyone can see what Jeremy is talking about.

As for Rey Ray (Jeremy) GASP I can belive you posted something in the Track forum.  LOL.

Hey Alan!

The pic I was posting of my Meanie is just an example of how out of whack the lining up of the PIN, CG, and MB was and how I didn't worry about letting the place where the CG was affect how I laid the ball out, that's all! God Bless You All and have a great week!

Do you have a pic, or can you desrcibe the layout you put on your RD1 then?  Any help will be appreciated.

Thanks,
Tyler

The Pic of the RD1 is almost exactly what his X-ception is looking like.  I know how I'd want to lay it out, and I'm just afraid that if I do lay it out like that I'm going to end up with like 4 oz of finger AND sideweight.  And I really don't think I could drill a hole big enough to take that much out...  as for the determinator, thats a good idea but the place were at doesn't have one (were in a university using whatever they will let us buy, which isn't much.  so a determinator is kinda out of the question).  Maybe Alan will bring his camera tonight and we can take a picture of the way its drilled now and you guys can help us out on it.

And Alan (or Alamo)... I just want you to know that I used to post a lot of things in the track forum, before you even knew what ballreviews.com was!!!

well no luck with the pic.  friend didn't have his ball there tonight.  probably talk to him about another way to lay it out tomorrow.  probably plug it up and weigh it out.  Just out of curiosity,  I'm still not real knowledgable when it comes to drilling (in the process of learning) about how much weight can you take out of a ball with a weight hole.  I mean if the ball comes up with like 3-4 ozs of both finger and side weight, is it even possible to take out enough to get it down to 1 oz?

Thanks
Jeremy

Hey Jeremy,

Please do the following and get back to me with your findings.

1) Layout the ball like you want (like Traumatize states) and then find your ending static weights (finger and pos side).  This will determine whether or not you have too much weight which can or cannot be removed.

Depends on the size of the bit, depth and overall design of the ball.  Some balls having higher rg's will remove slightly more weight compared to lower rg balls which are designed to be lighter around the core.  If he's using grips, we're limited to the diameter of that insert.  We have more flexibility in the side weight hole.

Personal experience, I've taken down 3.5 ounces of pos side weight.   However, if you use a 1 1/4 bit, be careful at tourneys which check specs because they can get picky about the bevel around the hole.  Nationals flagged me one year and let it go the other 2 years (same ball) so it depends who you get checking your equipment at the tourney.

Hopefully your starting top weight wasn't too excessive and then it wouldn't create as much imbalance as you'd think.  Keep me posted, thanks.
