jmeineke Posted January 9, 2010 Posted January 9, 2010 I saw a list a while back about where to find certain types of metal (like if you need 5160 get some leaf springs, 1095 get some ???) but for the life of me I can't track it down now. Can someone point me in the right direction? Quote
rthibeau Posted January 9, 2010 Posted January 9, 2010 It used to be on IFI as BP 0002, but until the blueprints come back, you can find the info across the street on anvilfire.com Quote
ThomasPowers Posted January 11, 2010 Posted January 11, 2010 Remember these are not "rules" but merely suggestions! So don't make a claim that you can't prove. (Not all leaf springs are 5160, almost no jackhammer bits are S series, etc; better to tell a client "forged from an old leafspring or jackhammer bit" than to say 5160 only to find it wasn't...)

Holzkohle Posted January 15, 2010 Posted January 15, 2010 Thomas. If jackhammer bits are not S series, then what are they likely to be? Thanks Jerry Quote
Steve Sells Posted January 19, 2010 Posted January 19, 2010 Thomas. If jackhammer bits are not S series, then what are they likely to be? Thanks Jerry Some are, but many are not. THIS is the point we are making about salvage. Quote
Holzkohle Posted January 20, 2010 Posted January 20, 2010 I understand that it can be a c--p shoot as to what you are working with in salvage material. i was just trying to get a feel for what the possibilities might be for the jack-hamer bits. Quote
ThomasPowers Posted January 20, 2010 Posted January 20, 2010 From my files: Grant, Sun 09 Oct 2005 JACKHAMMER bits have a hole down the center and go in a percussion drill (jackhammer). Paving breaker bits are solid and go in a paving breaker. Yeah, I know, most people call 'em jackhammers. Having owned a company for 18 years that produced millions of them probably makes me a little pickier than most. For me, if a customer ordered a 1" x 18" jackhammer bit, I had better send the right thing. As an aside to this, I've had just about every bit made spectrographed and never found one made from a tool steel. The largest manufacturer (Brunner & Lay) uses a modified 1045 for all their bits. Vulcan used to use 1078 (a high silicone 1080) but have changed to a boron steel in the last few years. Most others (Delsteel, Pioneer, Ajax, Tamco) use either 1078 or 9260. I Had good success using 8640. You only have to remember that B&ampL is water quench and the others are oil when you use them to make other tools. Me: S series would make a great bit and it's suggested as a use in Machineries Handbook. *however* it would be several times more expensive than a plain steel bit and harder to repoint when worn as the heat treat is fancier too. Just like stainless steel would make great car bodies---but save for the Delorean you don't see it used because of the cost! Quote
