Probably a dumb question, but how do you know when you arrive at a certain grit when polishing a ball. Say you use a 1000 grit polish and apply it on a spinner, how do you know when you arrive at 1000 grit? Is it all trial and error, or is there a formula or a hint that I can use to know what grit that I have taken the ball surface to? How can you determine a 1000 grit from a 1500 grit? I love the Abralon pads for the accuracy of the grit, but am lost when adding some polish. Thanks in advance!

The grit of polish or sandpaper is refering to roughness or the particle size of the grains that will leave your surface at a certain finish. Think of it this way, you can polish a surface with 1200 grit polish and because of the particles or grains within that polish the surface on your ball will stay within a certain surface finish range. So if you polish your ball for five min.'s or fifteen your surface finish will be within a certain range that the grain structure will allow for that polish. So if you want a coarser finish for oily lanes you would go to the lower grit's . But to try to answer your question if you start out with a sanded ball it would take you at least 7-10 min's to reach the surface finish that 1200 grit polish should give you. If you are just touching up a polished ball 2-3 min's is more than enough. I'm not a bowling ball finish expert but I have worked surface finishes and their measurements for the last twenty five yrs.

Thanks for the reply.
So then, if I sand with a 1000 grit Abralon pad, and then put a 1200 to 1500 grit polish on with a wet sponge, I can hold it up to 7 minutes and it should be alright. I was hoping to get the ball through the dryer heads cleaner, and still get a good backend finish. I guess however, that if the grit polish wears off while applying, the ball will get shinny, lose more surface and have less backend. Back to trial and error :>

Peace

kyroy,

Do you want sanding lines or the grit under the polish to have effect?

I suppose the grit under the polish. Isn't that what will make it work when it gets through the heads? Although I am old, I am pretty new at this surface preparation.

So.......kyroy then you don't want to use a compound polish like a Storm Step 1, 2 or 3. You want to wet sand to whatever grit you want under the polish and use just a polish not a compound polish that has grit in it. Understand?

With a heavier grit like 500 under polish with sanding lines running perpendicular to your track you get a different reaction than using a compound polish say to 1500 or whatever you might have. Does this make sense?

Ask charlest if you need info. and do some searches on coverstock prep. charlest knows a whole lot.

Thanks Scott! It make sense to me, now that I think about it. The compound polish would change the surface, and defeat the purpose of what I was trying to achieve.
Incidently, I have run several searches on various coverstock preperations, but always seem to get "There are no Topics or Replies that match your search criteria." for an answer, or something that does not relate to what I asked. I guess I will learn. Thanks again for the tip. I bowl this afternoon, and have enough time to prepare my ball.
Peace
