Author Topic: Sunk thumb slugs. What to do? (Read 6241 times)

Easy10pins · « **on:** June 16, 2009, 12:06:08 AM »

Over the past 3 weeks, I've had 2 balls, (Wild Ride and Chainsaw), suffer sunk thumb slugs while bowling.

Is there anything that can prevent this from happening besides not using them?

I realize the weather out here in the desert may have something to do with the issue.

Any thoughts or suggestions?

What the heck is a sunk thumb slug?

if you are referring to them sinking into the hole leaving the coverstock edge above the the top of the slug, they have to be drilled out, and a new one installed. make sure the slug hole is not deeper than the total length of the slug or it will happen again, or the slug is fully seated to the bottom of the slug hole before cutting the top of the slug off. Been there done that !!

Whenever I put in a slug I mash it completely into the hole using my drill press or a rubber mallet, if necessary. Of course I also put an appropriate amount of superglue on the walls of the hole first. Guess that's why I've never experienced a "sunk" thumbslug. If you're paying someone to drill your balls, it's time to find a different driller!

I'm in the desert, only had one slug ever do that and it was my fault. Turbo's are shorter than Vise's and I, just being stupid, drilled a bit to deep. Later the glue let go, not sure why, and the slug 'sunk'. That's never happened again, it really has nothing to do with where you are, just a poor drilling job or lack of attention to detail, IMO.

Take them back to your driller and have him replace the slugs and put them in properly.

If the thumb slugs are sinking into the hole, he is not inserting them fully into the hole before drilling them and not gluing them in.

Ask Parker about it. I remember this happening to him during a show a few years ago.

I believe the slugs my driller are using are (obviously) short than the hole drilled.

I guess it's due to the heat out here in the desert and the different rates of expansion between the ball material and the slug material.

I thought about going back to NOT using thumb slugs at all.

In fact, I am looking and/or have been to a new driller. 2 of the balls this guy drilled for me have been about an ounce out of specs. Then again, it has prompted me to learn how to layout and drill my own equipment.

Could you call Parker for him and get the answers?

It just means your drilled is drilling the hole too deep, therefore leaving space between the bottom of the hole and the thumb slug when it sits flat at the surface of the ball. Got nothing to do with slugs being shorter or heat or humidity. Have him drill the initial hole about an 1/8 to 1/4 less in depth and if the slugs needs a little cutting down no big deal. Your best option being that the holes are already drilled is to drill ou the thumb slug, but obviously not the whole thing as the next one will just sink again, and re-do the thumb.

The issue with your response is that if the hole is drilled too deep the slug will obviously be below the coverstock when mashing it all the way. Obviously your holes aren't too deep when you drill them. The glue has nothing to do with it, just simply the depth of the initial hole.

I drop some ball plug into the bottom of the hole and set my thumb slug in that and let it dry. But I use Exactatcator thumb slugs. You can do that with solids, but don't drop and ball plug into the thumb hole until the thumb slug is drilled out. It might take a little cleaning of the thumb slug after the plug material dries, but I haven't had a problem with a sunken thumb slug since I started doing this.

Barry, only problem with your method is if you want to bowl a regional or try for a national PBA spot you have to be able to see the bottom of the hole in both fingers and thumb

The depth gauge on your ball drillers press is a wonderful piece of equipment and a metal span rule to measure the depth of the thumb slug would be a wise decision too. I've had slugs and griplocs sink on me recently and now I've got my press marked on the depth gauge so that I bottom out slugs and griplocs so this doesn't happen anymore. I little planning ahead makes a world of difference.

Raiderh20boy,

You are correct but after the ball plug dries, you could drillout the little bit of ball plug at the bottom of the hole. the thought would be the ball plug stays under the thumb insert on the outside edge preventing the insert from dropping. The best method though as already stated is for the thumb insert to bottom out in the thumb hole. The plug material at the bottom of my thumb holes just gives me a little piece of mind.
