best price on HT oven

[rocketmann]

Who has the best price on paragon HT ovens ?? I know that Tim Zowada has great prices on even heat ovens but I want to use 120 v.. FWIW I don't want to build my own.

I want to use 120 v..

No you don't. I thought I wanted 120v. I was wrong. Just thought I'd share.

Rob!

 

[rocketmann]

why is that Rob??

rocketman,

This is the best I've found and getting pretty close, now that taxes are done.
Let us know how it goes for you.

I considered building one, but ultimately, I know I want all the digital controls, so Paragon is the way for me (unless someone comes up with something else soon).

Thanks for the link..

Rocketman,
Why 120 instead of 240? Sorry have to ask.

just got min today.$907 deliverd for the 9 in at knife kits. took about a month to get here. now i just have to learn how to use it . was doing a search and found this thred.

 

[rckendall]

Yeh guys, I'd like to know why 220 instead of 110 also. I have both but the logistics for me is easier with 110. And that is what the small Paragon is.

Help us out, ok?

Thanks,
Richard

I recently bought the 110 volt knifemakers furnace and am pleased with the results so far. I'm sure it heats up slower than a 220 unit but it comes to soak temp in about 1 1/2 hours. I'm in my shop doing other things anyway so I don't see this as a problem. My biggest objection is the small height of the knifemakers unit. It's a little tricky sliding large knives out with the little head room provided.

Sorry I took so long to get back. I had an AMOCO kiln in 120V. Even with the small chamber, it would get to temperature but 1950 took about 3 hours! That pretty much meant heating the kiln and coming back later to put the steel in because I didn't want my knives in that long.

The 120v configuration will eat up everything available to the circuit. Anything else will have to wait till later or go on another circuit. (shop heater - beer fridge?)

I would consider a 120v for a second (tempering) oven but not for my primary. Just my experience.

Rob!

I'm really surprised you guys don't know? Why....everyone knows that 240 is twice as good as 120. DUHHHHHH!

My Paragon is a 120v. It works fine for folder or hunter size blades. If you make Bowie size knives with a full tang, you need the 240v because the oven size is bigger. I can only ht a Bowie with a hidden tang, which is added after ht.

I have a 120v Paragon. After getting a new heating element, it took forever to come up to heat. I contacted Paragon, got a newer element, and time dropped radically.

AS for bowies, you can build a steel frame that fits against the door, line it with kaowool/imswook, and heat treat the bigger blades without a problem. Essentially you make the chamber longer. The kaowool works so efficiently that it takes only sloghtly longer and works great. The only trick is to wedge something in to the door open switch so it works. Make sure you have a tight seal with the kaowool. My frame sits on the door when it's open.

One of the reasons I wanted to use 110 is that I only have 1 220 outlet in my shop and it runs my KMG..So if I'm heat treating I won't be able to grind...Also the 220 outlet is not near where I would like to put the oven, meaning I would have to carry the thing around a lot more than I would like to. But with that said I may still go with a 220 unit because I found a good deal on a oven..

220 will use half as much electricity and the oven will heat up quicker. Run another 220 line to where you want your oven to be.

Okay, I am confused. Electricity is sold by the kilowatt hour. Watts=volts x amps. How will the 220 use half as much electricity as the 110 version?

110 volts @ 15 amps= 1650 watts = 1.65 kilowatt

220 volts @ 7.5 amps= 1650 watts = 1.65 kilowatt

I think I must be missing something here, could someone tell me what? I am not trying to be a smart ass, I am just curious.

 

[rocketmann]

the 220 unit is 11amp 2530 watt, and the 110 unit is 13 amps and 1560 watt. The 220 unit heats up much quicker so you don't have to run it as long..

 

[bigbcustom]

OIC so the 1/2 as much electricity was an estimate based on a guestimation of time involved in ramp up to heat, and the savings of electricity in overall use not a statement of efficiency per unit time. Okay. Thanks for the clarification.

 

[Don Hanson III]

Half as much may be a little strong, let me just say, 220 will use less electricity.

Now, an elec motor wired 110 volt will use twice as much elec as same motor wired 220 volt. Correct me if I'm wrong here.

 

[Rob!]

I'm no electrician, but I think I've got this one right. 220 will only draw half the current but essentially the same power. There are a few complicating factors such as line losses, efficiency of the energy conversion and the time over which heat loss to the atmosphere is occurring (longer time for the 110).

In the end, you probably aren't going to notice much change in your electric bill. Your considerations should be for best handling of the steel and your time constraints.

Besides, if you buy a 110 oven, it will make a great tempering oven when you decide to move up.

Rob!
