What is a negative rake scraper? It is a tool that has a top bevel, which changes the geometry of the tool and makes it more user-friendly tool and catch resistant.
In this video, Jimmie Allen of Boxmaster Tools, will cover how to use and sharpen your negative rake scraper. Basics include how a burr assists in cutting a clean edge.
In addition, special guest Eric Lofstrom will be diagramming the negative rake concept, and demonstrating some alternative methods to sharpen tools for use with exotic woods and acrylic material. This will include how to tune the burr - hone or change the structure, to work with these materials.
During this video you will notice the use of constructed wooden sharpening platforms that Jimmie designed for use with his One-Way platform - it adds a safety feature and maintains consistency.
In addition to scrapers used for fine finishing, Boxmaster Tools offers negative rake scrapers that can be used for removing bulk material. The entire length of the double-ended tools is heat treated, giving the owner added value. There are specialized profiles that will be appreciated by beginners and experts alike.

This video has a great deal of content. I have watched it more than once. Great summary of what is in here at mark 35.00. Thanks Jimmie, keep making great Boxmaster and DWay tools.

Glad it was helpful! Would also add that unlike when you use a light touch to sharpen your bowl gouges, when sharpening your Neg Rake Scrapers - don't be afraid to push in harder to create a good burr. A coarser grit is also optimum if you have the option

I finally bought the 5/8” double-sided flat bottom boxmaster tool. It’s much more beafy than it looks online. Works so much better than anything I’ve used in the past. Holds an edge well even in rock maple.

Whether hogging out or making a final pass, I enjoy the heck outa my Boxmaster negative rake scrapers. I especially like the Big-A** 1-1/4 or 1-1/2 that I bought from you in Portland. The heft of the thing keeps the vibration down and makes a better cut. Thanks for showing how to change the cutting edge of the NR scrapers. That was very helpful and looks easy to do.

Very nice video! I especially liked how comprehensive it was. It starts with how you grind scraper to how you can work with it and the different options of burrs. The pace was perfect and gave me a chance to digest what was said and done!

Great! Glad to hear it is working for you. Would love to see some pictures of what you have going on. jimmie@boxmastertools.com

Well I’m sold! I’ve been lookin for some scrapers to add to my tool rack and I’ve tried to repurpose some standard scrapers. They’ve worked sort of OK, but sharpening proved to be a pain as the handles keep getting in the way. So the double ended tool with the quick release handle is extremely appealing. Jimmy is it best to call you directly to place an order, or should I go to D-way? I’ll probably be placing my order Monday or Tuesday. Thanks for the informative video, it was very timely. Cheers, Tom

Tom - feel free to give us a call, happy to go over what's available and would work best for you. Jimmie

Actually I machined a new mild-steel tool post with these tools

How do the wooden platforms attach to Wolverine metal platform? I don’t want to drill through the metal platform. Thanks!

@JimGriec0 3 года назад

Great video! I do not have a neg rake yet. Which design and size do you recommend to start off with? My max diameter pieces are 12". I do both end grain and spindle work. Thx

@d-waytoolsboxmastertoollin2220 3 года назад

In the Boxmaster line I would recommend the 5/8 Double Curved. For 12 inch stuff in the D-Way line I would recommend the small or medium Round Nose negative rake scraper. They will become your favorite tool. D-Way Tools & Boxmaster Tools Jimmie Allen 360 689-4541

Is there anything important in creating the plywood raised platforms? Do you have any diagrams for making the platforms?

@jimmieallen4965 4 года назад

There are no plans or drawings. I make them 100 at a time. They are only $5 apiece and come with mounting screws and directions for mounting. We make them simplify the process and make sharpening easier for people. They are available on the D-WayTools.com site. Feel free to contact me if you have any questions or concerns.

Green wood. Try that for the same amount of time on seasoned wood

@d-waytoolsboxmastertoollin2220 2 года назад

Kent, thanks for watching the video. To your point, all wood used (in this video) was bone dry eastern maple. The burr on the tool was created using our 80 grit CBN wheel. If you have any of these tools and need assistance in usage or fine tuning your sharpening, feel free to contact us. Jimmie / D-Way & Boxmaster Tools / 360 689-4541
