Hey all

I have made the radius dish plunge....

I am now in need of sandpaper -- What do you guys use?
Big sanding discs?
Sticky back roll paper?
Regular sand paper + adhesive (What kind, so far it all peeled off on me)

Then... Where do you get it?

Thanks

John

John,

I have 80 grit specially made for dishes, 24 inch diametre for $20 per sheet. Piecing bits together (like floor sander paper) just does not work, I tried it. John at Blues Creek might have it for a bit cheaper.

I get mine from mcsdirect.com and order sanding belt in 24 inch width and 60 inch length. I ordered 80 grit Aluminum oxide. For $23.00 its enough to cover two dishes with a bit left over. I used 3M spray adhesive to glue to my radius dishes.

the paper I stock is a heavy backed sand paper stock. It has the adhesive on it . $17.50 plus shipping. I carry 60 , 80 , and 100 grit. Check out this link http://www.bluescreekguitars.com/catalo ... da038143e8

You Don't know what you don't know until you know it

i got mine from a skip at the local joinery place
used for the big belt sander
might be a bit dull some belts better than others
or you could buy a belt off them either

I went through this recently. John @ Blues Creek is definately the place... great paper, best price

I use some PSA 6" discs from Harbor Freight. Works great for for me. When a certain spot begins to wear out, it just takes replacing a few of the discs.

I want to have two different grits for each radius so when I order the discs should I go 60/100 or 80/100? Im leaning towards 60/100.

Ed, why do you need two grits? I use the 50 grit discs (at the bottom of the hollow forms list) from LMI who is also an OLF sponsor.

Hey Ed, you will be very surprised at how quick even grit cuts. That is the grit I use because it is a compromise between fast cutting and smooth enough to glue to. I used to use two dishes as well, one for the go-bar deck and one for sanding but now I just one for each radius and put sandpaper on it and then when I want to glue I just put some paper over the sandpaper. So, you really only need one grit.

Shane do you mean you use 100 grit? I only assumed I would need two grits, one for quick removal and one for smoothing.

Ed, I just use 80 grit. It is aggressive enough for good removal (I don't pre-profile my sides but my sander is motorized) yet it leaves a smooth edge for gluing. Even by hand with a decent dish this all you really need. My dishes are double laminated from 3/4 inch MDF prior to spinning them so once done they about 15 pounds that really helps as well.

I agree 100% with Shane , you only need 1. I personally like the 80 grit. 60 gets to be a bit aggressive and lets feathers, and 100 is too slow. 80 is just right.
