fat pete Posted October 21, 2007 Share Posted October 21, 2007 ok, I figure most of your punches and chisels are made by yourself....considering your working with some stainless, tool or just plain old steel and you want to use some punches for making eyes or some kind of texture finish...I guess you make them....cool How? Chisels are relatively self explanatory. any angled or straight edge could be ground or existing chisel could be reworked...the punches have me somewhat pusseled. I could make a rise and/or dent in the tip. I could see somekind of set up for the drill press. I could see making an olval by drilling in the stock a litle and maybe distorting the hole with a hammer and grinding the edge..but how would u make an eye for instance?

Dave Hammer Posted October 21, 2007 Share Posted October 21, 2007 Heat the end of the flat-ended punch. Punch a small ball bearing in the center. Grind around the indentation to your satisfaction. Heat treat. Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted October 21, 2007 Share Posted October 21, 2007 That works really well, If you want a more correct shape like for a horses eye make a punch and you can use mild steel that is just like the shape of the eye and the shape of the lid around it. Heat some tool or spring steel and punch the one you made into the hot tip You need a left and a right.... Quote Link to comment Share on other sites More sharing options...
HWooldridge Posted October 22, 2007 Share Posted October 22, 2007 You can also drill the end with a small ball mill or drill bit, then heat and flatten into an oval. Quote Link to comment Share on other sites More sharing options...
RainsFire Posted October 22, 2007 Share Posted October 22, 2007 dare I say you could use a dremel.. with a small carbide round bit and carve an eye into the punch, or carve the positive and smack the punch onto it a few times.. Quote Link to comment Share on other sites More sharing options...
gerald Posted October 22, 2007 Share Posted October 22, 2007 If you try the ball bearing method, drill a shallow indentation into a piece of scrap to hold the bearing still while you sink the hot punch point into it. The little "socket" will help you keep the bearing in place so you can get a better strike and you won't have to hunt it after it get through bouncing off your shop walls.

fat pete Posted October 22, 2007 Author Share Posted October 22, 2007 oh 1 other thing heatreating...nessecary or not..simple air cool? Quote Link to comment Share on other sites More sharing options...
Ian Posted October 22, 2007 Share Posted October 22, 2007 depends on the kind of steel Pete, some steels air harden some don't, if it's mystery tool steel then try air hardening first then work your way down quenchants from softest (or rather slowest) to (hardest) fastest. Do it that way and you'll eventually find the right one without risking the steel. It could crack for example if its an oil (slow) quenching steel, and you try water quenching it (faster). Others can explain this better and more technically than me, this is just a rough and ready explanation. Quote Link to comment Share on other sites More sharing options...
rusty_iron Posted October 22, 2007 Share Posted October 22, 2007 Gday Pete, Another hint, put a center punch mark in the end of the punch you are making, it makes it easier to locate the ball bearing or round punch when you place the punch over the bearing - its very hard to be sure you have it centered when it yellow hot and your in a hurry. the center punch mark means you can feel when you have it in position - simple and quick. Get yourself several of each ball bearing size, you do loose them at the most inopportune time :-) you can make the eye punch 'eye' shaped by squashing it a little - side to side. When using car coil springs, I now water quench - no I have not had any break - instead of oil quenching, as they were just too soft -perhaps I need a thinner oil???. I draw to a dark straw/bronze, but have used punches drawn past blue. Try the oil first if you are using car spring, you can always reharden and temper if its too soft.
