Rubin sandpaper, my relationship with it.

[iamnothim]

I think it has to do with the grain. Ao tends to dull as it heats up. That will give you that 80 starting to finish like 180 grit.

I'm almost exclusively using Granat these days [wink]

Yup, yup, yup.
Rubin drives me nutz.  (Now that's an annoyance  [smile])

Kev.

I just grab the paper that's closest to me.  [smile]

Me too. As long as its the right grit Im good.

When I got my first Festoy sander, I got a whole stack of different grits. I did not know the difference between the names on the packages.  I don't really get much time in the shop, so I still have all of those different grits with different names.  I discovered Granat, maybe a couple of years ago.  I had been reading so much here on the FOG about the Granat.  I needed something to really cut for a thray I was making where some of the strips had not lined up properly and I needed something to cut rapidly down to something close to flat.  I was at my Norwalk toy store and rummaging thru the stack of discs for my RO 150 and noticed a 10 package of 40 grit Granat.  I grabbed the package and ran.  That stuff cut!  And it LASTS.  I was amazed.

I had a package of Rubin 80 grit in my stash that I used for the next step up in grits.  That did a smoother job than the 40 grit Granat, but i did notice it did not cut as well after a few minutes.  I now check every time I go in to that toy store for higher grits in small packages of Granat.  I have not had much chane to use the higher grits yet, but do have a large table (large project for my small shop) where I expect to find out how the higher grits of Granat will work.  I still have plenty of discs for the grits from 100 and higher, but will be out of rubin for the lower grits. I will know better the comparisons by the time I finish up in the spring.  I have been cutting back on landscaping work and will be finding more time to pay with my toys and sand paper. 

As soon as I get thru spending $$$'s on grass seed and fertilizer, I will by thinking seriously about my next toy, an RO 90 for some smaller jobs i have lined up for this winter projects (after the table)

Yes, that's the downside to Rubin, it dulls very quickly, which makes it expensive to use.

The original Rubin really did suck for longevity but the Rubin 2 seems to be an improvement but not to the point of using it instead of Granat. I find on most of my projects I have had to use twice as much Rubin 2 compared to Granat negating any possible cost sving.
