RO90 STF stack capacity?

[Scorpion]

Some Amazon reviews say each "bin" holds a 100 and others (older reviews) say no way.  Which is it?

I get I can make my own insert and hold more.  I may eventually but don't have time at the moment.

Thanks

It depends on the abrasive grit. I'd guess that 100 x 400G takes about the same space as 25 x 40G.
(that's a rough estimate so don't blast me if it is off by a bit)

Why not make your own insert for a systainer?  I made this insert to accommodate the grits that I normally use.  It's easy to see which grits are running low.  When I get back to the shop, I replenish as necessary.  I've never run out of any particular grit on a job site.  I'd have to be working with some pretty gnarly stuff to go through 100 sheets in a day.  Just sayin'...

    I think 100 is a bit optimistic as a general quantity. You can get 100 of a thin abrasive (Brilliant 400) if they are pressed down. Trouble is when you open the case they tend to spring up , Brilliant in particular. I have a variety of types and grits in mine. I would say a workable average is 50. A couple examples - 60gr Granat about 60 - 70 because it stays stacked tight .... tends to stick to itself. Same for Rubin. Brilliant tends to be springy so more like 40 unless it is weighted down with something, but then the weight takes space.

I've just been and counted a few sheets in mine!

Seth is spot on - grit does make a difference, but not a huge amount in the higher grits; much more noticeable in the 40, 60, 80 range than the 220, 320 ones. I counted the the P100 and P220 delta sheets (all Granat) and I have just over 50 in each. I would guess you could get maybe 80 at a push, but again, as Seth points out, they're springy so you may lose them when you open the case.

50-70 depending on grit seems to be a good usable range.

Definitely depends on grit. Personally it doesn't matter for me as I buy abrasives in bulk and only take what I need for the day in the Systainer. The rest are on a shelf in the workshop.

Willy, was just looking at your thread, the original image still shows, but the other images further down in your post are missing.  I do prefer the way you've set up your partitions, as the sheets stay in place better than when stacking up as the Festool insert would have you do.

Thanks for the heads-up, Gary.  I had to reload the first one and didn't think to look further below.  They've been reloaded.

Thanks all for the feedback.  To summarize - grit impacts stack capacity.  Makes sense.  Can't fit 100 in general.  Most only carry what they need and leave the rest at the shop (doesn't suit me because I stay in the shop but I get it).  Custom solution is better if you want capacity.  Also get it. 

Looks like I'll hold off and go custom.
