  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Induction forges

    How much voltage have you tried using it with? The more voltage the more current and power is generated. Several people have used the 1000W modules with a 48V power supply and are able to heat items as thick as 1”.

    Induction forges

    According to the information on Amazon the coil is 50mm. I don’t know if that refers to the inner or outer diameter, but the crucibles I ordered are 50mm as well and different heights. If they don’t fit then I could either widen them or make another one with some copper tube.

    Induction forges

    I’ll have to find a good way to seal the mini water hose, but even if a small leak does happen, it is only a very small quantity of water moved by the mini water pump. Commercial induction heaters pump cooled water through the coil from a small reservoir, that is cooled continuously to get rid...

    Induction forges

    I see. I’ll make a video of my build if it works fine, so every one can feel more confident purchasing the unit. I’ve looked at some commercial units online that look pretty similar to a welder and plasma cutter. I’m a bit curious about how it would work for someone to use an old welder as a...

    Induction forges

    What do you mean? I have watched several videos on how to build an induction heater, I was about to order the parts from digikey; but none of the videos use a water cooling system for the coil, they only cool the mosfets with the fan. That's probably because they are only 1KW but this one is 2.5KW.

    Induction forges

    I just ordered that induction heater along with a set of graphite crucibles. I should receive them on Thursday. It’s probably only $100 because it’s a kit of parts. I like that because it allows me to design a more custom machine; but, of course I’ll test the unit before I add to it. The only...

    Induction forges

    Amazon has several high powered induction heaters available for around $100. They also have some lower powered heaters. I don't know how much I should trust this unit, because of the fewer reviews, but I think it would still be better than fabricating one myself...

    Induction forges

    I was doing some research on building a good coal forge, when I came across an article on the induction forge/heater. Depending how much it would cost in electricity, a heater that efficient would be very useful for wrought iron work, and maybe blade smithing if the coil were big enough...

    Blade smithing

    Yeah, I ordered that book a while ago, along with a book on Damascus steel. It has a lot of useful information.

    Blade smithing

    I followed the best heat treatment given by Larrin Thomas, the designer of the metal. I used plate quenching to prevent the thin 12 gauge blade from warping.
