Scuffing the SI ?
« on: February 15, 2006, 01:13:22 PM »
I've got a smokin inferno which is very touchy and over/under. I'm a medium speed/low rev bowler. I was told to scuff it but I don't know which grit will work best. I've got a ball spinner and plenty of sand paper to use. The ball is in box condition and there are some days where the ball will be very squirty and weak in the back end and some days where I have to keep me speed up and be very acurate.

Which grit should I scuff it down to? I've got sand paper in grits from 320 to 1500 and I have these 3M scotch brite like pads in Maroon and grey. I don't have any ruff buff though.

Help would be appreciated.

I was experiencing the same thing as you until I changed the cover. I used grey scotchbrite pad with medium pressure. It dulled it up nicely. Man does this ball move now! It starts earlier and smooths the breakpoint out alot. It still has a very strong move on the backend, but more of a hard arc instead of a snap. It has not squirted on me since. Carry remained awesome.

The pads I have came in the abrasive package with the ball spinner I purchased from vertex. I've got Maroon, and gray pads. I don't know if they are scotch brite or 3M. Is there any difference? I just know that the Maroon pads are the courser of the two.

Scotchbrite is made by 3M, so yes that is what you need. The grey is 800 grit and the maroon is 320 grit.

Here is the list of the different colors/grits available. It will come in handy.

SCOTCHBRITE GRIT CHART (courtesy of Charlest)
3M Scotch Brite Nylon Pads:
7445 - White pad, called Light Duty Cleansing - (1000) 1200-1500 grit
7448 - Light Grey, called Ultra Fine Hand - (600-800) 800 grit.
6448 - Green (?), called Light Duty Hand Pad - (600) 600 grit
7447 - Maroon pad, called General Purpose Hand - (320-400) 320 grit
6444 - Brown pad, called Extra Duty Hand - (280-320) 240 grit
7446 - Dark Grey pad, called Blending Pad (180-220) 150 grit
7440 - Tan pad, called Heavy Duty Hand Pad - (120-150) 60(?)
Green Scotch Brite is available EVERYWHERE. It's 600 grit.
Blue Scotch-Brite is considered to be about 1000 grit.
(The value inside the parentheses is directly from 3M.)

Use the grey pad to barely remove some of the shine. Then try it; if yo uneed more, do it again just slightly more. You don;t want to pass the point where it works. Other wise you'll need Brunswick;s High Gloss polish (a good polish, get some, if you haven't yet AND some Rough Buff. You will want them.) to re-polish and start over again.

If you had 2000 grit, I'd suggest that to do the entire ball, BECAUSE from your words, I assume you just want/need a small change to the surface. If you use the grey pad over the entire surface, you'll get a much earlier and stronger overall reaction. It will be a different ball for a condition for which you probably already have another ball.

I'd also suggest a very high grit first. The grey pad makes a big change in reaction from a polish. I made very good experience with 1.500 grit and 2.000 grit, being a slow player with medium revs. I still get very good length with such a finish, but the ball reads the lane at the breakpoint much more consistently than a polished surface. The finish will be sheen, almost glossy, but with the bare surface of the coverstock.
You shoudl be able to get some high grit pads either in a DIY store or in a special shop for car maintenance, in the colours section.

I hit the SI with a gray pad last night. I have yet to bowl with it and will do so tomorrow night. I've noticed that the scotch brite pads don't leave as many visible lines as sand paper. I'm sure my ball would look different if I had used 800 grit sand paper opposed to the grey scotch brite which is supposedly 800 grit.

My SI has a consistent reaction and is pretty predictable. However, it was the over and under that I need to deal with. It is notorious for leaving corner pins and even the pocket 7-10 a few times.
