bill k Posted September 17 Share Posted September 17 I recently got an induction heater. Holding the work in the coil without arcing was difficult. I made the work holder pictured below. It has proven to be a great tool, making heating various work pieces much easier. Quote Link to comment Share on other sites More sharing options...
Daswulf Posted September 17 Share Posted September 17 Smart work Bill. I don't know much about the big units but my small handheld unit has coil covers. Do they have anything like that for the big coils to protect against an accidental bump? Quote Link to comment Share on other sites More sharing options...

The machine I got came with a covered coil. A youTube channel "ej of the anvil" says he doesn't use them as they burn up when contacting hot metal and make a mess.

Daswulf Posted September 18 Share Posted September 18 They are technically a consumable. With my small inductor they recommend not "overheating" them as it deteriorates them. Over time they deteriorate anyway. I have had coild touch the metal as well. Mine are built on so non replaceable as per the company. If they are replaceable I'd go with using them and your shelves. Unless cost prohibitive. Quote Link to comment Share on other sites More sharing options...
Frosty Posted September 18 Share Posted September 18 Using guides on machinery is normal. Were induction heaters not out of my price range I'd have guides and guards for them. I was already sketching different ideas while I was searching the web for a heater I could afford. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
bill k Posted September 18 Author Share Posted September 18 I have enjoyed the heater. It does a great job. My wife saw a picture of a candle holder that had a conical base. The base was about 2.375" OD. I got some 2" pipe. I made a coil using 4 feet of 1/4" copper tubing wrapped around a piece of 2 1/2" pipe. The heater got it to working heat in under a minute. With the heating power turned to the maximum, I began to get sparks. I turned the heating power back and was able to soak the pipe at a yellow heat without sparking. I am sure there is a lot to learn about the various adjustments. Quote Link to comment Share on other sites More sharing options...
Daswulf Posted September 18 Share Posted September 18 I could see a couple rollers or v rollers being useful for moving the piece back and forth to heat a larger area. Quote Link to comment Share on other sites More sharing options...
bill k Posted September 18 Author Share Posted September 18 (edited) This material wasn't too heavy so it moved pretty easy. For heavier stock rollers would be nice. Instead of V-blocks I used two pieces of 1/2" flat bar to stabilize the stock. Here is a link showing the setup in action. Edited September 19 by Mod30 Remove excessive quote.
