Potatoes and Evaporust

I've got an even more basic question- why are you folding the sandpaper into fourths anyway? What's the application? Sorry if I'm missing something obvious!

Fourths are typically a more manageable way to use full sheet of sandpaper.

I typically do NOT sand with a full sheet of sandpaper. I do not know of anyone that does. Perhaps we have a different idea of what a full sheet is. My concept is a sheet 9" x 11".

Speaking about 1/4 sheets of sandpaper, both my Home Depot and Lowe's actually sell 1/4 sheets CHEAPER than equal amount of full sheet sandpaper.

I get packs of 6-1/4 sheets for $1.50 which works out to equal $1.00 per full sheet. They sell packs of 3 full sheets of the same stuff for $3.97 or ~$1.33 per sheet. So, I save $0.33 a sheet by buying the 1/4 sheets.

May not be a lot but it takes pennies to make millions and I try to do everything I can to save money. Check your areas out. I'll bet you find the same thing.

Are they the SAME paper? If so PERHAPS the 1/4 sheets were cut from full sheet production rejects(badly cut/torn/???, but still usable after recutting to 1/4 sheet size).

I'm not at home to measure them. Have to wait till 4:45pm. Do you suspect an err??

NO I merely want verification. I am under the impression that some(early?/all?) Greenies had bench tube OD of 1 7/8". I notice a ridge in the end casting holes where MY bench tubes attach. I assume your 1 7/8" version end casting do NOT have these. The ridge properly centers the 1 3/4" Bench tube I have.

This would imply that when purchasing USED end castings of Greenie vintage, the possibility of an improper version is possible. Just trying to understand a potential GOTCHA!

I am not sure(or I have forgotten) if early Goldies had 1 7/8" Bench tubes. I do not think the gray painted Goldie benchtubes were 1 7/8". Goldies were produced in both Gilmer(early, 3/4HP) and Poly-v(late, 1 1/8HP). I do not know if all early Goldies had non-painted bench tubes.

Well of course they're not the same paper....no two things are THE SAME!!!:D:D Seriously, they are the same brand of sandpaper (Norton 3X brand). I don't know whether or not they are production rejects. They look and function the same so if they are, the attribute is hidden from the consumer and if that's the case, they probably wouldn't sell it any cheaper. Being a QA guy, reputable companies will never sell rejects or substandard product where there is either a cosmetic, or more importantly, a functional difference unless it is clearly identified as such. Even then, companies would resist selling these products in the commercial market because of the negative image it implies. (i.e. poor process controls).

just a couple of things I did that worked well for me. I used the evaporust for my way tubes and bench tubes but the pvc pipes I used to soak them in didn't go quite past the height of the tubes. Then I filled the pvc pipes so they were soaking a little more than half of the tubes then I would flip them after a period of time, so I didn't have to use quite as much evaporust, and it was easier to check the progress of the rust removal. Also when I was done I strained the evaporust through grease filters to get all the rust out to make it even more reusable. I got the grease filters at smart and final and they just look like oversize coffee filters, which would probably work as well.

WHO said anything about CUTTING them?????? I said I folded a sheet. I did NOT say I CUT them.

If you are folding the sheet to CUT/TEAR them, fold the abrasive sides against each other. This allows you to obtain a tighter fold(you can really apply pressure to a SMOOTH surface(the back of the paper).

OK jpg, looks like I need to reword my initial question. I'll tell you, communicating iin writing can be very difficult, especially when you try to just blast something out. I ALWAYS know exactly what I mean yet try to get that down in writing!!

I'll type it just like a bronx New Yorker would say it. (excluding the choice words) Read with a Bronx accent.

I got a whole , you know, bunch of stuff to sand. I got one sheet of sandpaper. How the heck do I prepare the stinking sheet in quarters so I can get the most life out of it....

[mickyd]

It has something to do with having to cut along the fold to the middle of the sheet one ONE crease. You then fold it , but I forgot how right now.

Your on to it.....

Give it to one of my kids. They'll have that thing torn to pieces in no time. The longer you let them have it, the more pieces you'll get.

Ok! If you are going to use scissors, I propose the following. after establishing folds, cut along one of the fold lines to the mid point.

Then fold the 4 quarters so that no abrasive side folds against another abrasive side. This eliminates the scuffing of opposing abrasive sides. As you use up two 'quarter's(two sides are exposed), refold using the same criteria(no abrasive to abrasive contact) to expose the remaining fresh quarters.

THERE! Thats my story and I am sticking to it!!!
