liang7079 Posted September 28, 2022 Report Share Posted September 28, 2022 Hello all : Has anyone successfully cut out Japanese scraper steel (0.5 mm saw blade) and made scrapers ? I have managed to cut one out with a tin snip, but find them really tough and difficult to cut ,any suggestions on how to easily cut these out please?

wm_crash Posted September 28, 2022 Report Share Posted September 28, 2022 Dremel with a small abrasive cutoff wheel. Use several plunge cuts if you are trying to cut a curve, don't try to cut along a curve with the wheel plunged, it can break apart. Don't worry about the rough looking edge, you'll shape it to your liking on the grinder. It goes without saying, but I will say it anyways: wear full face shield!! cheers, Cosmin Quote Link to comment Share on other sites More sharing options...

JacksonMaberry Posted September 28, 2022 Report Share Posted September 28, 2022 Makes damn good scrapers, exactly as Crash suggested. Quote Link to comment Share on other sites More sharing options...
Bill Yacey Posted September 29, 2022 Report Share Posted September 29, 2022 For reasonably hard steel, it's usually enough to score it with an abrasive cutoff wheel ie. Dremel, and then clamp it in a vise with the scored line just above the jaws, and give it a quick hammer blow. It'll just snap off along the scored line.

HoGo Posted September 29, 2022 Report Share Posted September 29, 2022 All my scrapers are from recyled saws. I cut them with dremel cutoff wheel. Make sure to dip the steel in water regularly during cutting to prevent overheating and remove every bit of steel that got too hot during cutting and shows bluing. The ccrapers I made from quality saws are excellent but some of the cheap saws don't produce very good scrapers (don't hold the burr very well). Perhaps they need some heat treating. BTW, what hardness would be recommended for scraper steel? Quote Link to comment Share on other sites More sharing options...
Bodacious Cowboy Posted September 29, 2022 Report Share Posted September 29, 2022 I've found that old Japanese saw blades make excellent scrapers. I cut them out with tin snips, with generous margins to avoid buckling in the final item, then refine the shape on a disk sander. I like the sander better than a grinding wheel for this task - nice big flat bed to rest the work on. Quote Link to comment Share on other sites More sharing options...
Rico Suave Posted September 29, 2022 Report Share Posted September 29, 2022 Beside Scrapers, undamaged sections can be give a second life as a miniature saw. Quote Link to comment Share on other sites More sharing options...
