Aquired OLD sandpaper rolls - good/bad?

[Toolfreaky]

Got this free barrel of old sandpaper rolls. I read humidity can destroy sandpaper. Just wondering what's the take on old sandpaper. Barrel says 'junk rolls'. Also had that musky smell.

I'd use it for random hand sanding. The backing is more cloth like than paper. Very hard to rip. Not much sandy bit shedding off.

if it works, use it.

Kinda nasty, but the price was right. If it works, it works. Is that a pile of small, crusty spokeshaves in the last pic?

 

[Toolfreaky]

Threw the bottom ones away and the rest fit in an overflowing 5 gallon bucket. They will sit in the shed to preceed my lifetime.

Yup, got these spokeshaves for free. Was a quick, all is free grab anything for 10 minutes, after tag sale. Thought they where dock cleats . Cleaned one but didnt find a name. What to do with so many?

Incredible. Use them as dock cleats?

I don't see how sandpaper goes bad unless the conditions are such that cause it to start disintegrating.

Ha, seems like a waste any idea the brand? Are people interested in these? Cleaned a few more and found some numbers.

Just kidding. They don't look-- to me-- like classic Stanleys or products from some other makers of that time. To my eye, they look like a lower-priced product, and spokeshaves aren't a high-tech item in any case. Someone may be along soon who will know more. But, heck, you could clean them up, sharpen them, and you'd have enough that you'd never need to stop a project in order to sharpen. I'll be interested to see if someone knows more about them.

What are you using the sandpaper for?

Depending on where it's been, there may be grease or other contaminants that can get onto your piece and cause fisheye when it's time to paint the part?

I doubt you are using this to restore that 1967 Camero project, so may not be a real issue? IDK?

Nothings in mind. Mainly would be for clean up and some basic wood work. Nothing that would require nice finish.

That's a lot of sandpaper

Belt sander belts go bad much quicker than regular paper, the seaming glue dies. Regular hand use, use them til the grit starts crumbling off .

XActo use to sell tiny spoke shaves in their kits. There was another cheap brand, where you could get a set of three, forget the difference between the three. (AMT?, Zona, someone else in the hobby trade). If they don't feel real cheap, might be luthier tools.

The adhesive can start to fail.
With belts, this means the belts are no longer belts.
With sandpaper, the grit will start to fall off, leaving abrasive grit all over your work.
I don’t know what adhesive would have been used, since the adhesive would need to be flexible and heat resistant, and water resistant for “wet” sanding sheets.
I suspect hide glue was probably used in the past for non-wet sanding applications.

Nothing wrong with old garage sale sandpaper if it's cheap or free. It might not perform like new 3M Cubitron but for odd jobs it's nice to have on hand. But some no name sandpaper is really bad so if I had a "significant" project I'd use the good stuff.

As part of a bulk tool buy at an estate sale, I acquired some belt sander sandpaper in a size that didn’t fit either of my 2 machines. So I cut them up as needed to fit my rubber block hand sander. That cloth backed sandpaper lasts way longer than paper backed and was basically free.

What to do with so many?

In the scrap bin for me. Maybe the bottom central one could be cleaned up and blade sharpened to be usable.

What if you aquire a 1922 Packard or similar car that needs its wheels smoothed?

For sanding belts, the tape that joins the ends goes bad and you end up with sanding strips.
.
edit: looks like this was covered already. I usually don’t discover the problem until the belt is on the sander and i squeeze the trigger.

the sanding belts/strips would probably work just fine for wood-lathe projects, though they look like a pretty aggressive grit.

If it were me, I'd pick out the best looking rolls, and either toss the rest, or offer it up for free for someone else locally to go through. no takers after a week, toss them.

I was thinking about the exact same thing.

I'd probably keep the finer grits and toss the rest.
