I have a Sears 2X42 belt grinder and have wanted a scotch bright belt, but have not been able to find one. So i made a buffer out of scotch bright pads and a 4"X1/4" bolt 2 washers and 2 nuts. I cut out rounds the size of a soup can from the SB pads, punched a hole in them, put a washer on the bolt, threaded on about 8 of the SB rounds, added the final washer and then put on the first nut as tight as it would go and added the second nut as a stop to keep the 1st nut from loosening. I use my 3/8ths drill and run it over a 500 grit hand rubbed blade to give a real nice finish. I have struggled getting out fish hooks on my rubbed blades and the SB pads have solved my problem. Since I am doing everything on the cheap I do not have a benchtop buffer.
 
Rio Grande has a selection of these and pre-made mandrel for the purpose, or just loose round sheets of SB of stacking like a buff.
I've been thinking of trying them.
Good to know it works!

Here is a pic. Habor Freight has a simular product for sale, but it does not hold up due to the fact that the spindle it is on comes loose, so I made my own and it works really great. Just make sure to get it really tight. I have also been using grinding paste with it. I know pic quality sucks, but you will get the idea.

Good to know. I used the free SB pads i got when I ordered belts from truegrit. I may look into Rio Grande though I may be too cheap to go this route.:D Thanks!
 
looks like a good solution, and its always good to solve a problem when you get by without buying new equipment (as much fun as new gear is...)

a friend brought me a scotchbrite wheel and he whipped up an arbor for it so that it would fit my bench grinder...works well for what i do. after about a 400 or 500 grit belt finish i take it to the scotchbrite for that extra shine. takes it to about a mirror finish. BUT...it is a little streaky so i might try this...looks looser and is a broader wheel.
 
Yeah, the cool thing about Big Smitty's/Rio's idea is that you're using loose sheets rather than the typical, firm scotch-bright wheel (which is also great for many things).

Main advantage I'd figure for knifemaking with the loose-sheet arrangement is, unlike the firm wheels, you can lay down an even scratch pattern over contours without rounding them off--such as the plunge area. It'd work more like a loose buff, but with a satin finish rather than polish.

It's some good thinking.

Thanks for the heads up on the fiber belts!

You guys are right the loose bunch of SB does not have the tendancy to round off areas like the plunge. It allows the abilityt to really clean them up.

It also does not leave streaks. It is also nice to use with grinding compounds at lower RPM's. Using the drill gives quite a lot of options when finishing. I am really happy with the performance and it ahs really helped me on my finish work. I have a kitchen knife that I just glued up the handle on. I will grind it tomorrow probably. When the handle is finished I'll post pisc of it so you can see the blade finish I was able to achieve.
