Cabinet scraper

[badger5149]

Looking for sugestions on a good high carbon steel about .033 thickness to make cabinet scrapers. They are flexable, we sharpen them with files at 90 degrees and then roll a burr with a hardened shaft. They should have some corrosion resistance. Thanks in advance, Steve

I had read that some Lie Nielsen scrapers are hardened to Rc 49-51.

I'd bet that a variety of steels will work for you. D2 is a bit more corrosion resistant than others and ought to be available for a decent price. Not sure of that thickness though.

There is another scraper design that is tempered to around Rc 62 and is rigid at about 1/8" thick. Stewart MacDonald luthiery supply sells them and instead of turning a burr, you create one with a grinding wheel. I've thought about making several one of these days.

Thanks for the response. I sharpen mine on a belt sander sometimes and it seems to work pretty well. I was thinking of having them water jet cut to size. The flexability gives them a much more controllable feel in my experience. I also use the 1/8 thick when I am hogging off a bit more wood.

For a proper scraper .032" is the right thickness. Belt sander doesn't do anything good for the blade !Do it by hand,
I don't offhand know what hardness youi should go for as long as you can burnish it without too much trouble .High 50s would be a good start .
I would pick O-1 or for some corrosion resistance ,A2.

I just remeasured a little more carefully and it is .028. I have been using the Banco from sweden. Most of the time I don't fool with rolling the burr and just use my file to cut at 90 degrees seeems to work fine. On line directions usually recomend rolling the burr. I will be taching a bow making class soon and wanted to pass out some scrapers, one of our most often used tools. I usually pay about $8.00 I think for a decent one.

Thanks , I am getting rerady to place the order and I don't know much about steel. Would I ask for high carbon 55 hardness and 0-1 corrossion resistance. Not really sure what to ask for.
