If you were buying a heat treat oven?

How long do your 220v's take to get to 1500? The 110v doesnt take any longer than about 15-20 mins to ramp up to that...i think you need to take into account that while you may be running 220v, your internal chamber may have twice the volume as the KM14....less to heat equals less ramp time. Theres a reason paragon offers the km14 in 110v and all the bigger ovens in 220.....
 
if i remember right last time i did a few cpm3v blades i went from cold to quench in about an hour thats with a 7min stop at 1550 and a 20 min soak at 2050

that is if i remember right i ll have to time it next time
 
One thing we have learned with our 52100 and 5160 blades is that you don't want to take them up to temp too fast, with the Paragon I can tell it to go to 388 f. in one hour, I like that feature very much. Very rarely go up more than 400 degrees an hour when tempering.

the evenheat can do that too and i have found that for tempering that if you do a slower ramp up that it doesnt over shoot your soak temp
maybe that should be one of those tips in the hand book
 
I would absolutely recommend it in the tips book, I would guess that a big part of the soft tips come from ramping up too fast. I have found that steel likes slow heats and rewards those who treat it right with stuff like performance.
 
the thread wouldn't be complete w/o me chiming
in and recommending building your own oven yerself.

For something like $200 in parts you will have state-of-the
art digitially controlled oven accurate to 1F.
 
Hi Darrel!!! I'v been using a para, for over 25 years now. or there abouts. Had to replace the coils once. Not bad at all. Would like to try 220, as it is a bit slow from about 1400 to 1900. Only other complaint, is I would like a deeper chamber. I'm thinking about having them add on for me. Hey! Those were great looking Iron Wood toys on (U..) Mike
 
Mike Lovett: is your Paragon an analog or digital furnace? Mine is analog and I have been trying to remember if they even offered the digital back then. Any help remembering would be appreciated... :)
 
Rashid11, I would gladly buy two or three of those.To be practical,my laboratory units (when I did research) rarely held to 1 degree variance,and they cost thousands of dollars.( few pyrometers are accurate to more than 30 degrees at 1500.)To build a good controller with any programing,would cost you $200.
That said,yes, you can build a controlled oven for less than the cost of a paragon - but it won't be a paragon.

Hey Darrel,

As someone working out of a house/garage not set up for heavy shop tools, I would certainly be interested in a good 110 HT oven.

Hi Fitz! Mine is the old Analog. I've heard of people having trouble programing the digital. Mike
 
i would have to say i would love to see a 110 oven. i dont have 220 in my garage so i cant use a traditional oven. if you find them could you please post a link
thanks
mike
 
Ideally, a longer, narrower chamber and 110V would make a perfect starter oven and a nice second oven. For me, anyway....:D

Sure would be nice to get some links on the different models/sizes available in the Paragon. I've googled it and came up with nothing.
 
Stacy -

Omega-type PID controllers are under $40 on Ebay. Add a K-type TC ($25 brand new from Omega or $4 on Ebay), an SSR ($5 Ebay), $10 worth of Kanthal, firebricks (15 x $2.50) and you're in biz. I am on 2nd generation of
mine (went 220V, longer chamber). 2hr long project. A bit longer if you want
it to look a bit nicer :)
 
I've had my Paragion for at least 15 years and never had a problem of any kind with it.

The digital controller is better than any commercial heat treat furnace controller I've ever used.

That said, if I could do it all over again I'd buy the 220v version simply because it saves heatup time and money.

Why not offer both versions, Darrel? And explain the difference in heating times.

By the way, I have no problem at all with the downward opening door. I see no reason to change that.
 
Just got the word from Paragon.
Knifekits.com will stock the ovens with a side opening door.
You ask we do!
 
I actually like the down-opening door.....the handle is counterweighed so you dont need to do any latches or anything to open or close the door...the handle weight keeps the door shut. Im not sure how their side doors keep shut.
