Hallo!
For those of us in need of an inexpensive altenative to a Paragon furnace does anybody know of an alternative?

I am especially having a hard time finding one that will accomdate large blades.

Tempering oven only, or heat treat oven? Wayne Goddard uses a modified toaster oven for the draw.
 
I also use a toaster oven sometimes for tempering up to about 400 F.
Use a good but inexpensive oven thermometer. Can't trust the dial settings.

As mentioned above, you may mean a 'heat treating' oven. That's is a lot bigger game - price wise.

Sugar Creek is about the least expensive HT furnace out there, analog manual setting. Look at Koval's catalog online.
You may try and find a used furnace at salvage barns from scientific companies or universities. Another option is some small ceramic kilns go high enough to HT SS.
Paragon and Evenheat make the big knifemaker HT furnaces. Evenheat costs a bit less. They both offer the very desirable programmability for complex cyling and annealing.
One can always try building their own with firebrick, coils, power supply and controller. Save a bunch that way.
 
Hey thanks for all the responses...

I use the kitchen oven for tempering my blades, cross refferenced with 3 thermometers. Unfortunately it is not extremely accurate. ANd I have hads some unacceptable variations.

Saving up for a power hammer so I am looking for a good alternative that is relatively inexpensive.

Will look up the ones mentioned.

Thanks,

shane
