Hope negative rake scrapers Round, extra long
The Hope scraper negative rake is made to finish your workpiece or to apply the finishing touch to the shape. The Hope scrapers are very heavy and are therefore hardly affected by vibrations. With these tools you scrape with the burr that you sharpen on the steel. That steel is hardened M42 steel. The toolholder is 20 mm wide, no less than 12 mm thick and 40(!) cm effective length. The part that goes into the handle is round (12.8 mm), so you can easily make a handle or use it in an exchange handle.
Due to its length, this chisel is most commonly used to finish the bottom of deep bowls and hollow forms. Because the cutters have been ground at a negative angle, they can simply be placed horizontally on the tool rest. The round scraper is made of M42 steel and has a diameter of 30 mm.
Bowls and hollow forms
The Hope negative rake scrapers are made to finish your workpiece or to add the finishing touch to the shape. The Hope scrapers are very heavy and therefore do not suffer from vibrations. With these scrapers you use the burr that you put on the steel. That steel is hardened M42 steel. The cutter holder is 35 mm wide, no less than 15 mm thick and 26 cm long. The part that goes into the handle has a diameter of 16 mm. This means that it actually fits in any standard handle. But of course you can also make one yourself!
Sharpen
As mentioned, you use the burr. You can put that burr on it with a diamond file. A coarse diamond file, for example grit 300. And now and then you have to go to the grinding machine. The round scraper comes with an attachment, so that you can sharpen it on your grinding machine with the help of a drill or cordless screwdriver.
