ACforge Posted April 11, 2017 Share Posted April 11, 2017 Hey guys, It's been a little while since I've been on here but I have questions. I have a half round horse rasp that I can see the letters A and R inside a picture of a horseshoe and underneath says made in U.S.A. I was wondering who makes this horse rasp? Second question is how can I save this image because I want to forge a knife from it. Thank you very much, ACforge Quote Link to comment Share on other sites More sharing options...
JHCC Posted April 11, 2017 Share Posted April 11, 2017 No idea on the first question, but the answer to "How to preserve the trademark stamp" is: Don't hit or grind it there. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 11, 2017 Share Posted April 11, 2017 I can answer the first question when I get home tonight and read it off my tools with it on it... Quote Link to comment Share on other sites More sharing options...
Michael Cochran Posted April 11, 2017 Share Posted April 11, 2017 I've seen that mark before, is it "Arnold"? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 11, 2017 Share Posted April 11, 2017 ATHA in a horsehoe is also a well known trademark on old tools. Quote Link to comment Share on other sites More sharing options...
C-1ToolSteel Posted April 11, 2017 Share Posted April 11, 2017 I'm having a hard time seeing you be able to preserve that mark since it is a half-round. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 11, 2017 Share Posted April 11, 2017 Grind the round side in that area and flatten with a wooden mallet, forge with anti scaling compound on that area. Quote Link to comment Share on other sites More sharing options...
JHCC Posted April 11, 2017 Share Posted April 11, 2017 What is this "anti-scaling compound" of which you speak? (Assuming you don't mean barbed wire or a cheval de frise, of course.) Quote Link to comment Share on other sites More sharing options...
CMS3900 Posted April 11, 2017 Share Posted April 11, 2017 It's used a lot in the heat treating process for blades. Products like ATP-641. Satanite or fireplace mortar in a pinch. AC forge, You could use anti-scale on it to forge, and acid etch it deeper later if need be. You may need to re-apply the anti scale a few times throughout the forging process depending on the product. Quote Link to comment Share on other sites More sharing options...
JHCC Posted April 11, 2017 Share Posted April 11, 2017 Fascinating. I was familiar with claying blades to get a hamon, of course, but hadn't thought about having such a coating during the forging stages. Quote Link to comment Share on other sites More sharing options...
Frosty Posted April 11, 2017 Share Posted April 11, 2017 I'll just flux a piece I don't want to scale and it doesn't interfere with forging. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 11, 2017 Share Posted April 11, 2017 Machinists are often wanting to avoid damage to their carefully worked surfaces and a number of different methods have been worked out to do so. A search on anti scaling compound will yield a number of applicable results. Quote Link to comment Share on other sites More sharing options...
