Nakedanvil - Grant Sarver Posted June 1, 2009 Share Posted June 1, 2009 Running off a few tong and thought some might be interested to see this. The induction is heating a part for me every 20 second while I'm forging the previous one. Sure nice in this hot weather. Quote Link to comment Share on other sites More sharing options...

Sam Salvati Posted June 1, 2009 Share Posted June 1, 2009 Nakedanvil, how are you forging these? Freehand on a PH? If so can I see your tooling (pretty please )? Quote Link to comment Share on other sites More sharing options...
Sask Mark Posted June 1, 2009 Share Posted June 1, 2009 Just a couple of sets being made there, eh? They look great! Quote Link to comment Share on other sites More sharing options...
Jmercier Posted June 1, 2009 Share Posted June 1, 2009 That's where an induction forge shines the most, they're incredible for repeated applications heating the same object over and over. Pretty impressive pile there ! Quote Link to comment Share on other sites More sharing options...
Arbalist Posted June 1, 2009 Share Posted June 1, 2009 Gosh that induction heater looks good! Does it cost much to run? Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted June 1, 2009 Author Share Posted June 1, 2009 (edited) ApprenticeMan: Well, you remember that 100 screw press I posted............ Jmercier: Actually I can put something like a 2" coil a couple inches long in and heat just about anything I want up to 1-3/4 and just move it in and out of the coil to get a longer heat. Arbalist: 'Bout 35 cents per hour on what you're seein', sometime I can actually use as much as $2.00 per day, usually less. Adds $35.00 - 40.00 to my monthly bill. Used to use around $300.00 per month in propane. My electricity is only 4.5 cents per KWH here. Some people pay 2 - 3 times that. Course it's only drawing appreicable current when it's heating a part, so working at the anvil it might actually be heating less than 26.324% of the time.

Sam Salvati Posted June 1, 2009 Share Posted June 1, 2009 Ahh ok, good to see you are putting it to good use Do you have a picture of the dies or setup you use underneath it? Quote Link to comment Share on other sites More sharing options...
Fe-Wood Posted June 1, 2009 Share Posted June 1, 2009 :DI just learned something neeeewwwww:D Tell me more about the induction forge. I have never seen one nor heard of one. I LIKE IT!!! Sounds efficiant too:) Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted June 1, 2009 Author Share Posted June 1, 2009 Sorry AM, too crude for prime time. Besides, if I showed you, then I'd have to kill you! Then you'd be mad it me. Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted June 1, 2009 Author Share Posted June 1, 2009 (edited) Hey guys: How do I link to another thread? like "Is This Induction Heating" for Fe-Wood.

Sam Salvati Posted June 1, 2009 Share Posted June 1, 2009 (edited) Ahh, one of THOSE secrets, the TOP kind I understand. They sure do a nice job, does the same set do the reins also? what a cool tool. Copy and paste the URL from the top address bar into the other thread.

Nakedanvil - Grant Sarver Posted June 2, 2009 Author Share Posted June 2, 2009 (edited) O.K. Mr Fe-Wood see if this works :http://www.iforgeiron.com/forum/f87/induction-heating-10605/ there MUST be an easier way Edited June 2, 2009 by nakedanvil Quote Link to comment Share on other sites More sharing options...

Fe-Wood Posted June 2, 2009 Share Posted June 2, 2009 Thanks guys- I went and did a little tour on the internet supper hyway. I like that technology!!! Can anyone give me a not so simple explanation on how it works? From what I gather, there is a current run through the copper pipe at a super high frequency. Is it like a microwave? Now if only I could afford one:( Quote Link to comment Share on other sites More sharing options...
Pault17 Posted June 2, 2009 Share Posted June 2, 2009 amen Fe-ood. and THAT is the eternal catch... Quote Link to comment Share on other sites More sharing options...
Walking Dog Posted June 2, 2009 Share Posted June 2, 2009 Induction Heating No, induction heating is quite different than a microwave. A microwave uses standing waves at 2.45 gigahertz, which will couple energy efficiently into things containing water or fats. The induction heating operates at a few hundred kilohertz, and does not create much of a standing or traveling wave. It couples energy efficiently into conductive things (metals) by inducing circulating eddy currents into the object being heated. Grant's induction heater operates in the region of 200-400 kHz, if I recall correctly, although there is nothing critical about the exact number from the point of view of the metal being heated. There are also induction heaters which are designed to operate at much lower frequencies with ferrous metals only (read magnetic), and couple energy efficiently up to the Curie temperature . These work by inducing hysteresis losses into the magnetic work piece. Induction heating of a ferrous work piece results from the combination of hysteresis loss and the heating caused by circulating currents in the work piece.

Mills Posted June 2, 2009 Share Posted June 2, 2009 An electric current has a magnetic 'current' associated with it. ie electromagnets. when the electric part reverses so does the magnetic, this creates heat. In an induction forge that is a desirable characteristic, not so much in a transformer. Quote Link to comment Share on other sites More sharing options...
Nakedanvil - Grant Sarver Posted June 2, 2009 Author Share Posted June 2, 2009 As Arthur C. Clarke put it: "Any sufficiently advanced technology is indistinguishable from magic"! Just call it magic and you don't need to understand it. Quote Link to comment Share on other sites More sharing options...

brianbrazealblacksmith Posted June 3, 2009 Share Posted June 3, 2009 I just got back from an event, and it was good to see that Grant Sarver was on this sight. He wasn't kidding when he said those were just a "few tongs". He and his wife make them in his shop at their house. He has come up with the largest selection of tongs at the best price and quality of any other tong maker that I've seen out there. He also makes many other blacksmithing products. I've only ran across Grant a few times at different events, but I noticed his work immediately and there was more every time I saw him. I think he's a genius. I'm glad to see you here on this sight Grant! Quote Link to comment Share on other sites More sharing options...
