>I need advice about sharpening the disc tip of the Sorby RS200 multi-tip shear scraper. The instructions are nearly worthless.They say the tips are sharp already & only require honing after extensive use. The disc had no burr, no bevel. I tried to use a diamond stone but still couldn't get it to cut cleanly. Any advice from turners who own this tool. Thanks

>I use the Sorby Multi-Tip tool and I sharpen the cutters on the grinder with a slight bevel angle. For me, the tool cuts better with a burr on it like I would use on any other scraper. This means that the cutter can't be turned over to cut on the other side, but have a 2nd tip with the opposite bevel angle for those cases where that will be required. It is a useful tool, and I don't mind replacing the tips when they are ground too small to be used.

>Dick, like Russ I sharpen mine with a burr also. I remove them from the tools and set them on the grinder tool rest and simply rotate them with my fingers. If the tool rest is set really close to the stone this is quite safe and I'm just removing the smallest amount of metal.
When you are first shaping the bevel you need to remove a fair amount of metal. I touch the stone lightly and then pull the cutter back 1/16" and let the air from the wheel cool the metal. If you don't do this failry frequently you will burn your fingers. After you get it shaped you are removing so little metal as you sharpen it doesn't get hot enough to be a problem
too hot to handle

>I ended up taking a small piece of wood approximately 1/2 x 1/2 x 3" and on one end drilling a hole for a thumb screw. On the bottom I recessed a nut for the thumb screw and CA glued it in place. Add a washer on top and it makes a great holder for all my scraper bits.
It avoids burning your fingers, but more importantly, I don't worry about getting the smaller bits caught in the space between the grinder and the platform. I didn't want to find out what would happen if it did.

>The instructions that came with the one I bought explain how to sharpen. It is done by hand for both types of cutter. Rather than using a stone, I use a plate of glass and lapping compound. In either method you place the cutter face down and rub/lapp it. Seems to work very well for me, removes almost no metal, is foolproof, and is fast.
