What have I got here?

I have drilled a 3" hole in the lid of my toploader and hang the blade from a steel wire. I use it for normalizing, annealing and hardening. Works great.
 
Thanks for the kind words, Klammer.

A few years back I was offered a huge side loading pottery kiln for free. I did not take it because it took 220 volt and drew 40 amps per leg. It would have made a great HT oven for a large shop, but was way overkill for me. It also weighed about 1000 pounds. It had a programmable controller, and shelves inside. IIRC, it fired up to 2400F. The chamber was something like 36X36X24"....not quite big enough for a sword, or I would probably have taken it.
 
Stacy, if you just designed some new folding swords, that oven would have been perfect! :)

Adding a PID control to that will be easy, as you just add a few components in the existing control box. All you will need are a PID, and SSR and heat sink, and a TC and sheath.

It will work fine for small size blades of carbon steel. Those units aren't good for much above 1700-1800F. I know the scale shows 2500F, but my car speedometer shows 120 MPH,too.

If you need help with the conversion, send me an email.

I picked up one of these small 120v kilns a few days ago for free. It appears to be in "as new" condition or at least hardly used. It is a top loader and I cut a 3.5" hole in the middle of the lid and angled the "plug" so it so that I could replace it during heating cycles. I installed a 20amp circuit in my garage for it and fired it up this evening. It seems to work pretty good and I manage to heat a piece of steel to non-magnetic so I'm assuming this would fit my needs.

Can you please forward me the info on the PID conversion you mentioned above? I'd really appreciate any help you can offer.

Thanks,

Chad
