Sandpaper questions

[gerryr]

When I first started making pens I had some of the black sandpaper and had problems with really light wood. On the advice of people here I started using Klingspor Stearate paper and have had no b=problems with tiny black spots since. Two nights ago at my local woodturning club meeting, the president was raving about the great deal he got at an auto body shop on 1500 grit paper, black of course since he had some there. He paid only $1.00 a sheet![:0] I mentioned Klingspor and after several people wanted to know how to get their paper, the president rudely informed me that what he got was the best sandpaper for wood and that the Klingspor stuff was undoubtedly more expensive. I couldn't remember the prices so I couldn't respond properly. I later checked and found that Klingspor is less than 50 cents a sheet. Since I am ONLY a pen maker and not a wood turner, I have no credibility with several members of the club, especially the president, even though I'm an officer(may not be for long though). Am I correct in believing that the black sandpaper is not a good thing to use for wood, or at least for light wood?

Gerry, I'm sorry to inform you, but the president of the club was right. Since most automobiles are made of wood, of course automotive sandpaper would be designed especially for working with wood. I'm surprised you would even ask! []

I have had the black from the automotive sandpapers end up on my light colored wood, and I have switched to using only 400 grit red, and micromesh (MM) up through 12000, the MM is expensive but can be washed and if not overheated last a long time. the problem with MM is that the adheasive and foam backing is latex based and melts at a very low tempature (I had this happen to a "friend" working on his second pen)

Cav, thanks for telling me that I was wrong again.[][]

Gerry, sometimes is just best to leave people in their ignorance. While there are some here who have had no bad luck using dark sandpaper, many others have. Just go with what you know and let the others go their own way.[]

Sad to hear about the attitude of your club president and other members. Happy to report, my club is not like that. Very laid back bunch of guys supportive of all types, and levels, of woodturning. I use Klingspore Gold and like it. I thought it was a bit pricey when I bought my first batch but it lasts so doggone long that, ultimately, it is a very economical way to go. And, it is excellent sandpaper that doesn't transfer color.

Gerry,

I did a group buy for the Klingspor AO Stearate sandpaper and love it. It lasts too long (and I turn too little) that I won't be buying for years.

$2.44 for each 5 pack

$17.58 for each 50 pack

Remember, you can also get a discount if you sign up (see the main page)

BTW, best way to convince them is to bring a sample and let them try it. []

Not to hijack the thread - but Dario, the website on your links has an A weight Klingspor AO sandpaper which I'm assuming is a lighter weight paper - it's found under "closeout sheets". The prices on those sheets are 7.95/50 sheets!!! Is this a good deal or better to pass on it and buy the better stuff?

The wet/dry sandpaper is made with a waterproof adhesive so it can be used with water as a lubricant for wet sanding. It can be used dry, but with caution.

THE PROBLEM:
The grit on the black sandpaper is clear. The waterproof adhesive is black. When the paper gets HOT the adhesive melts and gets on the wood.

THE SOLUTION:
Don't let it get HOT. Using a lubricant will keep it from getting hot. Sanding very slowly will prevent it from getting hot. Only one of these will work if the wet-sandpaper is used dry.

Feel free to quote me to your president if you like. [] As much time as I have spent working for the government, though, I doubt that he will pay attention.
