There Goes the Thumb Slug
« on: June 26, 2006, 02:20:28 PM »
Just curious...anyone else have a thumb slug come completely out of your ball while you were bowling?  I was pracitcing with my RAW HAMMER DOOM today and the thumb slug came completely out....don't they glue those things in...or are they just pounded in?

In the shop I work in, we score the slugs first with a scraper, then apply a little superglue inside the hole and then press the plug in.  Never had one come out yet.

if you sand the slug down before you glue it in, it will hold it better.

With turbo grips new slugs you don't have to prep them as much but it still helps.

I've seen slugs come out because of cracking and core material falling apart around the slug. And when someone boiled there ebonite one, the slug came out.

I've noticed that coldhas the MOST effect on super glue. When it gets really cold, the glue get's fragile, and when there it impact being throwning the down the lane, or slamming them into the back of the car.
 
Climate also has a lot to do with it. I live in Las Vegas and I set the air conditioning in my house to 72, outside in the summer its about 100-115. I drive an S.U.V so my balls are only in the outside temperature for about 2 minutes at most. But people who drive cars and put their equipment in the trunk don't think about the fact that, most if not all trunks in cars lack air conditioning that makes the temperature in there around I would guess 110-125 degrees. 30-45 degrees is a big temperature change in that quick of a time. That temperature change cn cause the glue to become fragile and crack.

I use Switch Grips and have also had this problem. I use 220 sand paper around the outer sleeve, wipe of the sanding dust, and use a quick setting epoxy.

One thing I have noticed that for some reason when I drill plastic balls, and I'm talking about 15-16lb plastic balls here, the holes tend to be a bit bigger compared to reactive, urethane or particle bowling balls, using the same exact bit. Plastic balls are where I have had the most problems with slugs coming out. Myself and customers included in this observation.
