Surface modification tools

  • Abralon Pads
    • Abralon Pads are manufactured by a company out of Finland named Mirka. These are considered the gold standard of surface adjustment tools, and are used by most ball companies. These abrasive pads have the abrasive, silicon carbide, on one side and velcro attached to the other side. These pads are 6" around and come in grits ranging in 180, 360, 500, 1000, 2000, and 4000 grit. This grit level is termed FEPA and the number is often preceded by the letter "P" to indicate this. So a 4000 grit Abralon pad is actually P4000 grit. Compared to woodworking sandpaper, which often uses the US or CAMI grading standard, a P4000 would be equivalent to a 2000 grit US or CAMI grade sandpaper.
    • These pads came into prominence when initially used by the Ebonite Corporation. Fun Fact: Only Ebonite can get pricing on these at discounted levels and have access to different grits than the public has access to.
  • Siaair Pads
    • Siaar Pads are manufactured by a company out of Switzerland and used by the Brunswick Corporation. They come in 6" round pads with various grits from 180, 4000 grit just as the abralon pads do. The only difference is the type of abrasive they use that Brunswick claims loses texture slower than Abralon.
  • Scotch Brite Pads
    • Standard Scotch Brite pads are also a good alternative for adjusting surfaces. While not as consistent as Abralon Pads, do a pretty good job overall. They have different grits based on color: Maroon pads are 320 grit US, green pads are 600 grit US, and light grey pads are 800 grit US and blue pads are approximately 1000 grit US.
  • Trizact Pads

Surface modification procedures

6 Sided Method

1. Mark a reference dot or line on the outside of the spinner bowl.
2. With the reference mark always toward you, place the ball in the spinner with the label of the bowling ball facing up.
3. With the reference mark facing you, rotate the ball 180 degrees toward you, the label of the bowling ball will face down.
4. With the reference mark facing you, rotate the ball 90 degrees away from you, the label of the bowling ball will face you.
5. With the reference mark facing you, rotate the ball 180 degrees away from you, the label of the bowlng ball will be away from you.
6. With the reference mark facing you, rotate the ball 90 degrees to the right, the label will still be away from you.
7. With the reference mark facing you, rotate the ball 180 degrees to the right, the label will still be away from you.

Note: All 6 sides the ball are now resurfaced evenly.

4 Sided Method

1. Mark a reference dot or line on the outside of the spinner bowl.
2. With the reference mark always toward you, place the ball in the spinner with the label of the bowling ball facing up.
3. With the reference mark facing you, rotate the ball 180 degrees toward you, the label of the bowling ball will face down.
4. With the reference mark facing you, rotate the ball 90 degrees to the right, the label will still be away from you.
5. With the reference mark facing you, rotate the ball 180 degrees to the right, the label will still be away from you.

This 4 sided method should only be used for cleaning and other non-surface altering projects, as 2 "sides" of the ball are not covered.
Note: Using the 4 sided method for surface alterations will eventually leave a ball out of round
