"DSPH?" you ask. Dead Sand Paper Hording.
My dad never met a piece of sandpaper that he didn't like. In fact, once he met them, he was reluctant to part with them! One of the things that I "inherited" many years ago--when he closed up shop as they downsized their home and eventually move to Florida--was a huge collection of used sandpaper!
Although he never spoke it out loud, I caught him doing it a couple of times and so know the practical outworking of his sandpaper philosophy. I'm sharing it here for posterity because I know there will be others in the future who will fall into the same traps (none of the current Creekers, of course).
Dad would use a piece of say 150 grit sandpaper until it would not sand any more. He would then put it in a pile, along with the multitude of other well used chunks. He would use that piece of clogged 150 on another project that called for 220 grit paper. He evidently figured that if it doesn't work as 150, it must have filled up most of the vertical space, and now would grind off much less than it did as new 150 grit.
I would sneak into his shop when he was still in their large house and gather up bags of clogged SP and pitch it. BAGS of the stuff, literally. Sadly, no one sneaks into my shop and cleans up.
And now, I about have to post a sign saying "You are NOT your father! THROW IT AWAY!!!" I'll be working away on a project and realize that I have not changed sandpaper for a very long time and that no matter how hard I push, or how hard I try and find a clean spot, the paper ain't making dust, just smoke and dark spots on the wood! And it's just sooooooooo amazing to me when I change to new paper and how quickly the marks go away... Kind of like not sharpening tools until it about hits you in the head that maybe, just maybe, the sucker is dull enough to use as a tongue depressor!
But then, I'm sure that no one else here does stuff like that. Figured I'd share so y'all could have a little Christmas laugh on me.
