I finally pulled the trigger on a 9" disk grinder with VFD 1.5HP motor. So does it make more sense to buy the 9" sanding disks (without adhesive) or good sheet paper and cut out? Would fellow disk grinders please share their preferences???? I plan to use mine for flattening fittings and to make beautiful, long flat grinds on swords.
 
Sheets are less expensive and there are more choices. If you get a strippable spray adhesive, Wayne Coe sells one, cutting your own sheets makes a lot of seance,.

I run a 1.5 vfd 9 inch and have a Rod Neilson disc on it, love it.

Plus, if you search ebay and other auction sites, there are often great deals on cases of SC abrasive sheets. I bought a case of 500 sheets of 400 grit Wet-or-Dry for $20.
Make a short stubby 2" blade knife to cut the sheets away after placing on the disc. One turn by hand and instant circle.
 
Yeah I'm getting the Rod Neilson..and I have the 3M feathering adhesive that Wayne sells. I was already using it on my smaller disk grinder. Where do you recommend to go for sheets? And do any sheets come in ceramic grits??? I use shop rolls and belts... I rarely shop for sheets...
 
Good sheet paper, and 3M feathering disc adhesive. That way you can peel off sheets
trim and you're ready to go. I usually only do flat grinds to order but you are really
gonna like the setup, would be my second choice after a belt grinder.

I recently started using a drywall circle tool to cut my sheets. Works pretty cool. +1 on the 3M feathering adhesive.
 
I use sheets because I can get good deals on it locally (right across the street actually). I use 3M super77 spray on mine though, cleans up easily with lacquer thinner after a couple changes.

I buy razor blades in bulk packs, and they work great to trim the sheet. As mentioned, use cheap spray/feathering adhesive to attach the paper, and then use the razor blade to trim to the disc.

Scott, from what I have seen, the 9 inch disc is an oddball size out there in the regular non-knife world, The big advantage of it is that you can use a standard sheet of automotive paper. Finer grits appear to be hard to find for the other sizes in discs I guess because most people just don't use them for woodworking. 400 is considered "fine" for most folks other than people doing things like painting cars.
 
Sheet and Ebay for the cheapest paper you can find.
Feathering cement.
Stick the sheet on and trim the paper to the disc in a few seconds.
I also covered my disc with a piece of black vulcanized liner material.
 
I've tried every paper I could find on my disc. The best cutting are the ceramic discs, but they're expensive.

The best choice, in my experience, is Rhynowet. It cuts clean and smooth and lasts, and at about $0.44 per sheet it's cheap. The really expensive sc papers seem like they lose their grit after just a few revolutions, and the super cheap stuff like from Industrial Abrasives just rubs the blade steel.

Burt Foster turned me toward the Rhynowet about 5 years ago and now it's the only paper I buy for the shop. :)
 
I noticed a big difference when I went to Rhynowet on the disc, especially in the coarser grits, the others would dull out fast, I was amazed.

Thanks Nick for the suggestion in another thread.
