oven steel guage question

[Guest]

OK So I just called the steel place x-link gave me, and got quoted $18.85 per sheet for 4x8 galvanized 26g. I want to do an angle iron frame on the bottom and I am thinking like a 3" bar up the edges and across the top to make it super stable. Then I have a totally solid surface to mount the door. This might be total overkill, but I like overkill

Should I go with thicker sheet than that? I thought it was going to be a lot more expensive, so I was thinking going thin and buy some cheep bars to make the thing real stable.

And isn't $18.85 a sheet rather CRAZY cheep?!?!?!?! i mean I socialized...I didn't just pop the question. And dood told me to come to him not the front desk or it would be more, but man that is like half what I thought it was going to be.

Re: oven steel guage question

Re: oven steel guage question

If I need to go thicker it's not an issue at that price. Do I need 20 or is 22 enough? no one mentioned 24 yet...do I hear a 24!?!

Re: oven steel guage question

discount steel quoted me 28 bucks 3 weeks ago!!

Id go 20g for the interior and 26ga for the skin.

Re: oven steel guage question

dood you got to shmooze a little

I think I like that idea too. 20g is for sure enough on the inside. The outside shouldn't be anything but a covering if its insulated right so the 26 should be fine. Hell, both sides of the door should probably be the 20g for strength too eh? I bet its only a few bucks a sheet more.

Re: oven steel guage question

I'm using .080 aluminum for the inside and 20 ga.studs for the framing.The door openings are renenforced with 1 1/2 in box tubing,but then this thing is 5x5x10

Re: oven steel guage question

I used 18 on the inside and 20 on the outside of my 4x4x7 oven it works great and if I build another oven I will do it the same way again.

Re: oven steel guage question

my oven is 16 gage in and out . takes a few more minutes to get to temp on the first run but stays warmer much longer

Re: oven steel guage question

Here is a material that I have been using for oven & booth construction as well as many other fabricated projects around the shop. This is a coil of 102" wide aluminum. It is .030" thick and the alloy is 3003-0 which is quite soft, making it easy to shear, form and rivet, but the flip side is that it marks and dings readily. My local heating & sheetmetal guy does the shearing and forming.
I have only about 12 ft remaining on this coil but will be getting another soon. Contact me if you want some. Shipping only makes sense in Southern Ontario or pick up, I am near Woodstock. Yes, alum = $$$... I will get a price on the next coil. On the OVEN pic you may see my handy viewing window. It the lense and surround that I salvaged from a halogen work light...nice thick high temp glass and it swings up for IR gun temp measurement.

I went with 24. 22, 20, 18 all will work long as weight is no issue. 10' sheets are a little tricky for 1 person to handle. You know how and what your gonna cut with? cutting and just handling the sheet metal was the biggest pain in the ass for me. I did mine all by myself.
Just frame all the sides and top with angle iron. Then you could use less metal studs, which makes it easier for the insulation. just some ideas

Re: oven steel guage question

ohhhh yea guys good stuff....

first off...Bob500ram...nice window! And how do you like that door opening like that? I have been having some crazy thoughts of doing my oven sideways instead of up and down and bringing the whole thing 2 ft off the floor so I dont have to bend over. I was actually considering a 2 piece door opening sideways instead of up and down because I didn't think that up and down would work well. It doesnt get in your way?

I think I am going to go with an angle frame on the bottom only. I am getting worried about it wicking the heat away to much. So the plan on the current piece of paper looks something like 4x4 by 8 ft long with the whole thing on 2 ft legs. Split front door. I want to do some tracks on the bottom for a rack...does anyone have a track system that is off the ground? I was thinking I could build a stand for my rack 2 ft off the ground, then have a couple pieces I drop into place between my stand and the oven to slide the rack between the oven and the stand. So for something big I could pull it out and remove the tracks and have clear space all around to work. When its time to go into the oven, pop the track back in and slide it in. I have a really bad back...so I put a lot of thought into making life a bit easier where I can Anyone see any major flaw in that idea?

On the cutting, I have an air shear. Cuts like butta! If you are doing anything with sheet and don't have one, man what a great investment. My sheets will be 4x8 so a little easier to deal with than 10 ft, but yea still pain. I got a couple people that are going to help me out.

Hey we got any engineers in here? Man I was trying to figure out load tables last night and wow that stuff just confuses me. Real question: What size angle iron for the frame? 2"? Got to think it might have to hold up like 800 lbs or so with the oven and parts? 8 ft span with 3 legs, on the ends and 1 in the middle. my thought was an 8 ft x 4 ft rectangle with a cross beam in the middle and legs basically. I could add some beams going across as well too maybe. I was thinking that the wall strength would be just fine to hold up the 4x4 area that would be open on each side.

here is a horrible drawing of what I am talking about. Though I think I will point all of the legs down at the same angle when I build it...
