Disk sander paper shredding

Hi folks - newbee alert.

I bought a Mark V from a friend at work which is an '83 model. He basically had it in storage for the last 25 years. Including the disk paper.

The 25 year old sand paper worked like a charm! (But now the remainder of it kinda buckled and puckered from it's backing so I can't really use it.)

BUT I just bought some local green stuff, took off the old paper, dissolved all the old glue, cleaned off the disk plate, put the new green sand paper on a warm disk and,..

It is now shredded.

I sanded two small pieces of cherry and it's toast. I really mean small, these pieces were about 2"x3" and now there's poc-marks and divots all over the sanding disk.

What are you guys using for 12" sanding disks and where do you buy them? I looked all over Grand Rapids Michigan and basically found only one place that carries 12" sanding paper disks.

Thanks guys

I buy mine from ShopSmith. They just happen to be having their annual sanding sale on this month. http://www.shopsmith.com/ownersite/catalog/sand09/

You might try 3M 77 brand of adhesive to attach them to the disk.

I've never tried anything other than what Shopsmith sells. Watch for a sanding sale and buy enough to last a while (til the next sanding sale).

It must be your lucky day as there is a sanding sale in progress right now.

It ends on April 30. http://www.shopsmith.com/ownersite/catalog/sand09/sn_velcroalumoxidediscs.htm

Buyers Alert: There are sanding disks and then there are velcro backed sanding disks (which require a velcro backer disk).

ONLY try using 3M 77. It releases when you want it to. Other 3M products are not so co-operative.

What do you mean by "green stuff"? I've never seen green sanding disks.

From the ad and the grits offered are you sanding or grinding something down? I have found that if I tried to grind something it generated a lot of heat and the heat breaks down the glue and the paper shifts. When the paper shifts it creates ridges, when these ridges hit the edge of wood they tear.

Remember when you grind on a metal the metal being ground conducts a certain amount of heat away but wood does not therefore all the heat gnerated remains to effect the paper and the disk.

You are absolutely correct. I did not complete the research correctly. I was looking for "green 3M sandpaper" and quit reading when I found it.

This is not recommened for wood. http://www.3m.com/product/information/A ... paper.html
