June 1, 200917 yr 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.
June 1, 200917 yr Nakedanvil, how are you forging these? Freehand on a PH? If so can I see your tooling (pretty please )?
June 1, 200917 yr 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 !
June 1, 200917 yr Author 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. Edited June 1, 200917 yr by nakedanvil
June 1, 200917 yr 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?
June 1, 200917 yr :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:)
June 1, 200917 yr Author 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.
June 1, 200917 yr Author Hey guys: How do I link to another thread? like "Is This Induction Heating" for Fe-Wood. Grant "the ferrous of them all"! Edited June 1, 200917 yr by nakedanvil
June 1, 200917 yr 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. Edited June 1, 200917 yr by ApprenticeMan
June 2, 200917 yr Author 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, 200917 yr by nakedanvil
June 2, 200917 yr Heres one from Mark Aspery's YouTube chanel.YouTube - Induction Forge Show and Tell video
June 2, 200917 yr 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:(
June 2, 200917 yr 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.
June 2, 200917 yr 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.
June 2, 200917 yr Author 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.
June 2, 200917 yr Sorry nakedanvil, I like walking dog's explanation better. Magic is cool but we no longer live in the dark ages.
June 2, 200917 yr could use that down here in florida have to look into that cool Could finally run A/C in the shop too without it all running out the chimney!
June 3, 200917 yr 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!
