Weight Removal
« on: March 16, 2013, 12:01:03 PM »
So I'm curious as to just how much weight could be removed from a ball by drilling the fingers deeper and utilizing a large weight hole?  I keep seeing some really interesting discontinued balls on ebay that are NIB and cheap, but usually 16lbs. Now I throw 15lbs.  But Im wondering if you could remove enough weight to get these things down to say 15lbs 8-10oz post drilling, so that there wouldn't be a huge difference with my 15lb equipment.  If anybody has tried this I'm curious to hear.

Thanks.

Correct me if Im wrong, I've only been drilling bowling balls for less than a year but at most you are looking at 2-3 oz when you drill out the fingers and thumb.  You would need a large weight hole to get it down from 16 even to say 15.8.  And when you are drilling a large weight hole, you are taking away your side weight.  I would say it isn't worth it.

Side weight doesn't correspond to ball reaction...  Worry more about having no core dynamics left once you drill through the guts of the ball.

What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?

Yeah I'm not talking about creating side/top/bottom/whatever weight.  I'm talking about removing enough weight so that I can throw a 16lb'r enough that it wouldn't throw my game off a whole lot when switching between my 15lb balls. 

So it seems that with deeper fingers and a weight hole I would be removing a max of 4-5 oz from the total weight?

You could drill the fingers 3 to 4 inches deep and do the same thing with your thumb hole as a pilot hole and then go over top of it with your slug hole and slug.

You probably could get a 16.00 ball to around 15.11 - 15.12 doing that.   Add in a weight hole to take out a few more ounces and you could get it to 15.10


In reality you are just drilling huge holes and removing the weight block dynamics of the ball.


I don't think you are going to get it to 15.8 (15 1/2 lbs) unless you start with a 15.12 to 15.14 total gross weighted ball.

Yeah I didn't think you could get it down a full half pound.   

Thanks for the info
