Scotchbrite Sanding
« on: September 25, 2019, 10:28:27 AM »
I was cleaning out some cabinets yesterday and uncovered a few boxes of maroon and green scotchbrite from probably 20 years ago. Like many, I graduated to the newer surface pads over the years (Abralon, etc.) and mostly forgot about the older abrasives.
 
Is anyone here using lower grit scotchbrite on the newer coverstock surfaces? I've never been thrilled with the longevity of Abralon/Siaair, and found the JOEST Use-It pads to be no more durable. I have a few rarely used balls I'm going to experiment with, but just curious about the experience of others.

I dont remember the grit ratings for the scotch brites, but my recollection is that we were trying to achieve much more aggressive surface preps during the pre resin era.  As we became more familiar with the friction characteristics of resin the trend went to much finer grits for surface adjustments.  Today we may start at 500 grit as part of a resurface, but that is consideted very aggressive.

I pretty much exclusively use scotch brites (and Trizact pads for higher grits) and save my abralon for rare occasions or putting factory on someone else's ball.  Since scotch brites are safest for particle balls and are good for quick sanding by hand lane side I just use them for everything.  Maroon scotch brite is equivalent to like 500 grit Abralon or so.  Generally what I use for the base of resurface unless needs a deep resurface then use very course scotch brite (like 260 or so equivalent IIRC).  Green and black are little over 1000 I believe equivalent and light gray is 1500.

Thank you for that link. That is definitely the best resource that I have seen on surface prep materials.  Nice job to whomever put it together.

I'm going to hate myself for asking, but I have to... Exactly why is Scotchbrite superior to other options for particle balls?

More likely to sand the urethane in the cover stock without rounding the particle material as well.  TBH have heard only really have to worry about this for first few generations of particle tech.  Guess I will find out since I also took Trizact 3 and 5k pads to AMB Centaur Particle I picked up recently.

In my opinion, scotchbrite became popular because it's main predecessor was sandpaper. On a spinner with water supply water can flow through the pad which made it easier to get a more uniform surface over the whole ball.

I also still use them occasionally, but typically the medium and finer grits rather than the maroon or green.  Their cost is less than the newer abrasives that can be expensive comparatively.

Having said that, a green pad with compound on it can produce an aggressive surface that can still be very useful today.  I compare it to Brunswick's older generation Rough Buff surface.  Changing speeds, water flow, and hand pressure can get some nice results without much cost.

It is best for those particles that are softer.  Harder abrasives will pare down the particles along with the cover stock leaving a relatively flat surface, but Scotchbrite since it is softer, will leave the particles standing above the cover which helps in oil.

FYI for BowlingForDonuts, Visionary used soft particles.

I don't know if this is true or not, but someone told me once that was one of the reasons for the perception of early particle balls dying.  Bowlers were using their normal abrasives on particle balls and sanding down the particles in the process so they did not have the old reaction in oil like they had before.  They blamed the ball and not their own actions for causing that.   Balls like the Chaos used glass beads as particles and sandpaper would level them down.  Of course, oil absorbtion was also occurring and we weren't removing the oil back then.

If this is untrue, please let me know.

You mean the one that was on Ebay where you outbid me with less than 5 seconds?

I believe this was the most significant factor in one's perception of their particle balls dying BUT not necessarily the only factor.

I never touched my particle balls with any abrasive,  and they still died.

I still have and use 2 particle balls-Yeah Baby, and Mega Friction- that I use scotchbrite on. I will grant you that both balls are weaker, BUT the oils are thicker. I religiously clean my stuff right after using. I use those 2 balls for control/predictability when some of the new stuff is unpredictable. Medium to light oil shots are in their wheel house. Just last week I used a burgundy pad-with light pressure by hand-on my blue Paradox to get the ball started sooner. While not often I still use scotchbrite pads.
