ciladog Posted February 16, 2012 Share Posted February 16, 2012 This video shows how I make eye punches for animal heads. I use a forging method called piping where the surface metal is pulled over the core. Enjoy. Quote Link to comment Share on other sites More sharing options...
David Einhorn Posted February 16, 2012 Share Posted February 16, 2012 Nice powerhammer fixture. Could you show the whole fixture and maybe describe it a wee bit? Quote Link to comment Share on other sites More sharing options...
John B Posted February 16, 2012 Share Posted February 16, 2012 Nice vid, do you normalise before you finish grind, file and finish the end, seems in the sequence you normalised after this, can you clarify please. Quote Link to comment Share on other sites More sharing options...

John, I just let the punch cool slowly after forging and it's pretty soft. Then I do the final grinding and and finishing, normalize once or twice before hardening and tempering.

It will show several versions of the taper tool. Should help before ciladog replies. Brian P Quote Link to comment Share on other sites More sharing options...

Tim McCoy Posted February 17, 2012 Share Posted February 17, 2012 Isn't the initial result of what you are doing something some of us refer to as "fishmouth"? Seems to work great whatever it is - I'll try it soon. Quote Link to comment Share on other sites More sharing options...
HWooldridge Posted February 17, 2012 Share Posted February 17, 2012 Nice video and great technique. I typically taper the stock, followed by normalizing then I chuck in the lathe, face off the tip and run a two flute ball mill into the end. Your way is a good blacksmithing method.

pkrankow Posted February 17, 2012 Share Posted February 17, 2012 I punched the end after shaping the punch, then ground to intent. I was rather not happy with how the punch upsetted while I was punching it (did that make sense?) I may have to try this since it is a simple looking technique and appears to provide a better controlled rim. Phil Quote Link to comment Share on other sites More sharing options...

Randy Posted February 17, 2012 Share Posted February 17, 2012 Phil, I know what you mean. I do the same thing, but leave the end a bit heavier than needed before punching. Then you can grind the excess off to the desired shape and size. Usually when we're forging we're having a hard time not getting the piping action. Now we can use it!

Old N Rusty Posted February 17, 2012 Share Posted February 17, 2012 What was the metal you used? I think a piece of auto lug wrench would do . Quote Link to comment Share on other sites More sharing options...
ciladog Posted February 17, 2012 Author Share Posted February 17, 2012 What was the metal you used? I think a piece of auto lug wrench would do . Rusty, that was a piece of coil spring so I assume it was 5160. Quote Link to comment Share on other sites More sharing options...

doc Posted February 21, 2012 Share Posted February 21, 2012 Great to see someone using a technique(pipeing) based on a result that most people only see as a negative. The use of pipeing to start the mandrel for DOM tubing is something they did back in the teens in industry. I don't know if this is still the process used. Good video ciladog Quote Link to comment Share on other sites More sharing options...
nuge Posted February 21, 2012 Share Posted February 21, 2012 Thanks for the lesson, what a cool technique. I can't wait to give it a go. Quote Link to comment Share on other sites More sharing options...
pkrankow Posted February 27, 2012 Share Posted February 27, 2012 I tried this today. It is easy to get the piping action, but less easy to control the evenness of the lip that forms. I will need to revisit it after I grind the end off the punch I (poorly) made. Thank you for the video. Phil Quote Link to comment Share on other sites More sharing options...
ciladog Posted February 27, 2012 Author Share Posted February 27, 2012 Phil,If you keep your hammer blows all the same and keep the punch rotating at the same rate the margins will come out evenly. Quote Link to comment Share on other sites More sharing options...
woodsmith10 Posted February 27, 2012 Share Posted February 27, 2012 thanks ciladog very helpful information,i tried it today and it works great! Quote Link to comment Share on other sites More sharing options...
deglen Posted March 7, 2012 Share Posted March 7, 2012 thanks very much for the video. I've been scouring the forum for a week now trying to find a better way to accomplish this than the way I tried - driving a ball bearing into a punched spot on the face of the tool. I think this will be much better. Can't wait to try it. Quote Link to comment Share on other sites More sharing options...
