rthibeau Posted January 30, 2013 Share Posted January 30, 2013 Dave, methinks you should just send me that hammer for proper training and start over to incorporate all the suggestions previously given. What are you using to punch the eye?? With a flypress I take that many heats.```` -_- Quote Link to comment Share on other sites More sharing options...
Albert A Rasch Posted January 31, 2013 Share Posted January 31, 2013 John, Great link, thanks for putting it out there! Fantastic work and great design. Albert A Rasch Quote Link to comment Share on other sites More sharing options...
FieryFurnace Posted January 31, 2013 Author Share Posted January 31, 2013 I'm using an 80 pound air hammer, single hit method. It's hard to line up and move around, which is most of what slows it down. But it is just down-right big stock for the hammer too. I took out the oak handle today and did a wavy-grain walnut handle with two crossed white oak wedges. I'm staining it now and will post pics when done. I also polished the face with 220, 340, 400, and then scotch bright. It's mirror finished now. Brent Bailey's work is quite nice. I got to see a lot of his stuff out at ABANA and I've used one of his sledges at Brian Brazeal's place. Quote Link to comment Share on other sites More sharing options...
rthibeau Posted February 1, 2013 Share Posted February 1, 2013 Make a jig that fits over the power hammer bottom die to hold the hammer blank in place, then it will be easier to get the punch set right....or you could make a jig the holds the blank and the punch in line together Quote Link to comment Share on other sites More sharing options...
FieryFurnace Posted February 1, 2013 Author Share Posted February 1, 2013 Make a jig that fits over the power hammer bottom die to hold the hammer blank in place, then it will be easier to get the punch set right....or you could make a jig the holds the blank and the punch in line together I would like an upper H13 die that is the punch. Bolt it on! The bottom would need some form of alignment tooling as well as stops to keep the billet from sticking in the punch. The problem with the alignment tooling and the stop, is the expansion caused by punching the eye. You have to be able to get the billet in and out, easily, to conserve time and heat. You would also need the alignment die to be adjustable in all directions and on all sides to allow for different sized billets. Sounds like a job for some heavy all-thread.

John B Posted February 1, 2013 Share Posted February 1, 2013 Hi Dave, When you get your top tool punch done, if you attach a stripper plate to the bottom tool, you should be able to get your punch out OK Maybe you may have to consider slightly altering your production process if you wish to accommodate locations.

FieryFurnace Posted February 1, 2013 Author Share Posted February 1, 2013 Stripper plate? Please define! I'm not familiar with that. I've got the new handle finished and the faces polished up. Thanks for bringing up these suggestions....it's really improved the hammer. Black walnut handle with white oak wedges! Quote Link to comment Share on other sites More sharing options...

jeremy k Posted February 1, 2013 Share Posted February 1, 2013 Dave - now thats the difference between a hammer and a NICE hammer - well done!!! Quote Link to comment Share on other sites More sharing options...
Chuck in Ms Posted February 2, 2013 Share Posted February 2, 2013 Now that is a Great looking hammer. Well done Sir Quote Link to comment Share on other sites More sharing options...
Pug}{maN Posted February 2, 2013 Share Posted February 2, 2013 Yup that's it! Now if they don't let you in will string them from a tree ! Quote Link to comment Share on other sites More sharing options...
Albert A Rasch Posted February 2, 2013 Share Posted February 2, 2013 Now there is a huge difference between the two examples! As you can see, It is still a hammer, but the finish has made a vast difference in the perception of your skills. And a stripper plate? That lends itself to way too much speculation.... best regards, Albert Quote Link to comment Share on other sites More sharing options...

dkunkler Posted February 2, 2013 Share Posted February 2, 2013 A stripper plate holds the punched object and strips it from the punch as the punch goes up. Quote Link to comment Share on other sites More sharing options...
Albert A Rasch Posted February 2, 2013 Share Posted February 2, 2013 DK, Thanks for the explanation. I was beginning to think I had missed something... And that's for power tools right? Albert Quote Link to comment Share on other sites More sharing options...
dkunkler Posted February 2, 2013 Share Posted February 2, 2013 DK, Thanks for the explanation. I was beginning to think I had missed something... And that's for power tools right? Albert Yes, they're used on presses, can be man powered like a flypress. I guess it would work on an air hammer if you can generate enough up force to raise the ram and extract the punch.

John McPherson Posted February 2, 2013 Share Posted February 2, 2013 Here is a picture of a hydraulic press with a stripper plate punching a hammer eye. Quote Link to comment Share on other sites More sharing options...
FieryFurnace Posted February 2, 2013 Author Share Posted February 2, 2013 Ok Yeah! That's what I'd need! A hydrolic press would be the nice way to do it.....in the absence of a punch press that is! Quote Link to comment Share on other sites More sharing options...
John B Posted February 2, 2013 Share Posted February 2, 2013 A stripper plate holds the punched object and strips it from the punch as the punch goes up. Not necessarily hold it, but should be clear of the blank being punched, basically just to stop the workpiece lifting with the punch. This may or may not work depending on your powerhammer. For production work producing hammers, drop stamps are the way to go. Quote Link to comment Share on other sites More sharing options...
dkunkler Posted February 3, 2013 Share Posted February 3, 2013 Thanks John, I wasn't quite clear. I meant hold as in it detains or halts its movement, not hold as in supports it. Quote Link to comment Share on other sites More sharing options...
FieryFurnace Posted February 3, 2013 Author Share Posted February 3, 2013 Yeah I'm not sure if my hammer could withdraw the punch. I wonder how you would tell without making all of the tooling and then blam, FAIL! I do want to sell my air hammer and build a new air hammer that's larger.....maybe 100-150 pounds. (Depending on what my compressor could run.) But that's another topic for another time. I don't see a punch press anywhere in my future budget. I suppose I could build a hydraulic press, but they are a bit slow. It'd take a honking press to punch 2-inch + material as well. One of these days I think it'd be awesome to get two GOOD strikers and two GOOD directors together and forge a couple 12-pound sledge hammers in the Brian Brazeal hand-hammer style. Metals calculator says a 3-inch solid 4140 billet 6.375-inches long would do the trick. I figure it would take one person holding the billet, one holding the tools, and two striking. Plus an entire spectrum of customized tools. It would be AWESOME though! Quote Link to comment Share on other sites More sharing options...
metalmangeler Posted February 3, 2013 Share Posted February 3, 2013 I have not been looking here lately. Really nice hammer especially with the modifications. I thin you and Trip did a nice job on those hammers as well. Quote Link to comment Share on other sites More sharing options...

yesteryearforge Posted February 3, 2013 Share Posted February 3, 2013 I punch Hammers with the handled punch that I got from Brian on my Iron Kiss in just two heats and its only the 50 # Iron Kiss These start out as round stock but dont finish up as a rounding hammer Quote Link to comment Share on other sites More sharing options...
