I didn't mean to sound confusing. In the beginning you were discussing the type of enclosure. That is simple. Now you are discussing the elements, convection, design, and control system. That is more complex.
Please don't take the following as argumentative or a personal attack. It is just my observation of you recent posts.
You arrived here a month ago. Your first posts were about steel choice to make katana and wakizashi. You haven't said you have ever made a blade that I can recall. You are in finance, and don't state that you have any particular shop skills. You want people to tell you how to build a grinder and a sword tempering oven. You have not discussed how you will make a sword or harden it. Your only information provided to us is that you are 47, and male.
I agree that occasionally someone comes up with a new idea. My grandfather was working for Bell Labs when they invented the transistor in 1947 (BTW, they also invented the IC, the binary computer, and Unix). I was doing electronics in the 1950's and 60's when the transistor finally found a use. From there to ICs to microprocessors was a short time. However, none of that was "new science". It was applying known science to new uses. To my knowledge no one said, "Heck., I think Ohm, Watt, and Marconi are full of crap", I am going to come up with something different.
Even Tesla, who was truly a mad genius was using known science.
Maybe you could get the guys on the "Oven Building Forum" to design your tempering oven for you. You seem to find them a good source.
Your plans are not viewable unless I make an account with the host. Not going to happen.
From a moderators point of view - One big advantage of having a paid membership is being able to post photos and files easier.
Stacy, i dont want to argue with you. I know you are trying to help me, but i am somewhat frustrated. The only thing that seems complicated TO ME, is what you are planning to give me. The rest is, as you say, a tube.
I'm not sure why you are parsing the tube vs an oven... who in their right mind would make a tube, but not an oven?
you may not remember some of my other posts in other threads but I have indeed discussed, though not at length, how I plan to harden this steel. You told me to buy some nuclayer, etc. I have nearly every book, video etc on the subject of making katana, in Japanese, korean and English. In fact, reading those books is what DROVE me away from forging to stock removal.
though I dont weld or plasma cut, i have about as advanced a woodworking shop as can be had without being a slave to WoodCraft.
You indeed mis-recall. I made several blades in my past. I lived in Japan, Korea and the PI. My last blade made however, was 25 years ago and I no longer have access to a traditional power hammer set up. I do have a charcoal forge(which we discussed) and you told me to go to propane.
back to the main, no one said anything about discarding known science. My point to natlek was that a fan is wholly not necessary despite "everyone" in the oven business installing fans. I'm NOT making a cube.
My drawing is a terrible version of natlek's most recent drawing of my tube, with the exception of having only one element. its the same drawing.
You imply that I haven't told you enough about myself. I'm not here to talk about myself really. Asians consider that bragging. We dont do that. if you want to know something ask. I don't hide behind the web and I'm easy to get to know.
I didnt know you had to sign up for anything to see my file. I'd be happy to sign up for a membership.
I genuinely think you had it right the first time. This is JUST a tube. it, just a 'toaster oven" as you said several times during the thread. And in fact, after I post the final to do list with pics, I don't honestly think anyone could say this was difficult. Certainly NOT a 2% only thing. Thats WHY I'm making this thread.
it doesn't have to be pretty or perfect. it's not art. It just has to repeatedly get to about 500 degrees f when I want it to.
The hardest part for me will be to wire up what you said you are sending. You've said you have the requisite materials to work with the part number I gave. I'm purchasing the insulation you mentioned in your emails. but for the .5 inch ceramic tubes, junction boxes, and high temperature 14 gauge wiring, I'm set.
Ill email you the photo. But don't judge my idea based on my drawing skills. I dont draw well.
To bad that my fan was not yet arrived so i can put together mu JUST tube and make some test video .I have three points / 3 thermocouple / to measure the temperature inside with fan on/off.Only one TC will be connected to PID to measure/control the temperature inside ........
