Title: Motion hole drilling
Post by: Supermo on July 24, 2016, 05:29:52 PM
I have seen the vid on the Motion hole drilling and it looks good to help maybe the bowlers who have not got a lot of revs and finish on their balls. What bowlers have tried this drilling and what effect has it had on their game. Thanks for any replies.

Have just seen a thread on this topic and it seems it would work better on a low RG ball. It seems that some bowlers have had good success with it.

Symmetrical simple design cores seem to work well.  For me, it gives a touch more length and a little stronger corner on the backend. 

I've tried with stronger covered balls (hoping to use on fresh), but this didn't work out very well.  Over/under reaction.  I needed dried, broken down conditions where I could move inside.  Under these conditions, the layout was money.  Really liked the layout on a Rotogrip Wrecker

Just be cautious because it adds LENGTH as well as increasing the backend (and, of course, the overall dynamics of the drilled ball)  over more normal or average drillings. The added length can be tricky for some people to handle.

I have done 3 Motion holes on various balls.  It's totally dependent on your stats. especially initial axis tilt.  Low tilt are better with Motion holes medium to high tilt better with P3/P4 holes.  Do more research on bowlingchat.net lots of info. there.

Best reacting Motion hole ball that I have is an original Yeti.

Thanks for your replies gents. I do have a Lucid which is now replugged is this ball a candidate for a Motion hole nothing to lose as its an old ball maybe worth experimenting with this one. The other one I have is a Columbia Pure Physics got it very cheap but never had it drilled yet.

I don't know if he's right or not, but my pro shop told me not to put a motion hole on an already plugged ball.

What the heck!! How else will you find out how these things work? I put motion holes on all kinds of plugged balls. It gives me an insight as to what I may want on a newer ball with similar specs!

Thanks for your help gents, I might just get it done as its an old ball and may well give me some idea on what the drilling does for me. We still have to experiment even at my age I still want to get better.

I've had great success with Motion holes on the Storm Optimus, Roto-Rrip Haywire and Roto-Grip Outcry... You can tweak the surface to get that drilling to read as long as one usually needs... CharlesT is spot on with length/dynamics/control... feels like it raises the balls RG substantially IMHO. I use it mainly on a THS when you get that weird grab in the front and the ping in the back from hold and you need to go left with your feet but look right to go around it.

That being said... they look awful on flatter shots for me unless i add a lot of surface.

The Storm Lucid is an asymmetrical ball from everything I've read the Motion Hole drilling is for symmetrical balls only

I put the mo-hole on a Columbia Severe Delirium (was on close-out).  Brought the surface to 1000, at it became a long, hi-rev, continuous control beast.  Pin is above ring finger, about 30 degrees over, CG in center of span.

Not true I've seen a guy try it on asymetric with good success

The motion hole layout works on symmetricals, it's a craps shoot on asymmetricals.  Asymmetrical cores are just that, asymmetrical, so you don't know what the area of the core you're drilling the motion hole in looks like.  So it works on some but not on others.  That's why Mo stopped recommending it for asyms.  --  JohnP

Drill away G.

I've since changed shops, but maybe he was concerned where the new CG would be after plugging?  Maybe good shops check (even a new ball) for the CG before drilling, but I've never seen one do it.

Anyway, I had a weight hole plugged on a Brunswick Ringer and added a Motion hole.  So far I like it.  Threw about 6 or 7 shots on Viper and it got down lane much easier and made a pretty strong move down lane.  I'll also throw in on a house shot on Thursday.

I always check a plugged ball for cg location, it usually ends up fairly close to the marked cg.  I only check a new ball if the numbers appear to be suspect.  If I'm drilling for someone that doesn't want a balance hole and using a layout that will be close on static legality I check the weights before drilling to be sure it will be OK.  Side weight will be very close to the check, finger/thumb weight will depend on the size and depth of the holes drilled but will give a good estimate.  --  JohnP

The motion hole did make a pretty good difference, but not enough to save this turd.  It does push the reaction further down lane with a little more oomph, but this ball seems to have a terrible core/cover match up for me.

If properly placed, make the hole bigger in 1/8" increments until you like the ball reaction.  You may have to skuff the cover as the hole size increases.  Operators need to know how to remove the weight correctly and still hit the core in the correct quadrant....  it doesn't require much critical thought...

Been there before.
