Sharpening Negative Rake Scrapers for Woodturning

Тәжірибелік нұсқаулар және стиль

Negative rake scrapers are very easy to sharpen. In this video, I will explain how I set up the grinder platform and sharpen the negative rake scrapers that I use in my woodturning. If you have some of my negative rake scrapers and aren't sure how to sharpen them, this is what you need!
Thank you to Stuart Batty and Bonnie Klein for showing me the Negative Rake Scraper concept.
Please visit my website to see more woodturning tools. www.cindydrozda.com/
If you are wondering where to get that grinder support platform, it is made by Stuart Batty Tools and sold by Woodworkers Emporium in Las Vegas USA. The platforms are not listed on the website, give them a call to ask about them.

You can do fairly well with the Wolverine platform by cutting out the notch around the wheel, or putting an overlay on top of it like I show in one of the videos. Robo Hippy also makes an adjustable rest that's good.

    I noted your angles or included angles seems to be mostly symmetrical, is that by preference or simply because it is easier because the platform angle is already set. Ie 25 degrees and 25 degrees.

    Edward, It doesn't seem to matter if the angles are symmetrical or not. Setting one platform angle and sharpening either side is good on tools that I might use either way up. I do some with a different angle top and bottom.

    Hello Cindy thank you for your videos but most of all the clarification on the subject matter. I watch several other channels and where I have a question, viewing your channel you have answered many questions. My question is are these various tools in this video purchased and you keep them sharp or did you make them from raw steel. If you have made them Could you please advise the best steel material “ the metal type” or number” to make a tool with and your best method of heat treating them. Thank You very much David Ray

    Hi David, You can either make Negative Rake Scrapers or you can buy them. The ones I use are available on my website www.cindydrozda.com/. If you make your own, use the best steel you can find and it will hold an edge longer. Better to buy the steel already heat treated. Heat treating HSS is quite a process.
