modular oven

[Popeye]

What you're describing is basically the way walk in coolers and freezers are built. They assemble fast and are just about air tight. If they used a different style insulation (high temp) they would be just about perfect for an oven... well, that and the cost.
Do a search on google, most manufactures show fairly good details.

"my bigest promlem is how to make a corner without the need for a special corner panels."

You only need 2 of these corner or end panels, no mater what size oven you assemble, it has a left and right end, always use the same panels for the left and right ends for any length.

You can build this so many ways, I can't explain in plain text very well though.
Make each panel so where they connect at the ends they overlap about 2-3" and only half as thick, over lapped and fastened the overlaps are full thickness. So if you build 3" thick wall panels, the ends are 1.5" thick and overlaped make the 3" from 2 panels.

i already thought of making left and right panels, but what about making the smallest oven you can out of 6 panels. there would be no left and right.

the factory i work in has ovens and freezers there were both modular construction, thats where i got the idea but i need it on a smaller scale.

i think i need to make some small models. i have been doing a lot of drawing and even more thinking. maybe it would help to actualy make some. but dont stop coming up with ideas!!

"but what about making the smallest oven you can out of 6 panels. there would be no left and right. "

I don't follow you there, unless your making a round oven like a ball there would always be a left and right, front and rear, top and bottom, at least I think so

[gomer950]

if you put 2 panels side-by-side there is a left and right. when you only have 1 panel it is both left and right. the smallest oven would use 6 panels, 1 for each side. so all panels are both left and right.

Doesn't make any sense to me?
Any oven will have sides, even a round oven though the sides would be round. I was looking at making an oven from an old junk electric dryer, so ya that would be a round oven inside.
I said something about a ball, well even if the oven were round like a ball there has to be a door to open to put parts in and take them out, wherever that door is, the left is left side and right is right side, so there are always sides
If you use only 1 panel as an oven, it must be hollow inside to put the part in it, so yes it still has a left and right side even then.
So no matter what your smallest size oven, make one side a left and one a right, you will always need a right and left side, even if basic shape is round like a dryer drum, and you want to make an oval, you still have 2 sides that are half round.

The Smallest oven would be a simple bread toaster, even that has sides. I do allot of plain flat fancy cut 1/4" plate steel. I should be doing one now instead of typing this since I have to ship it tomorrow, but I have all night to get it done so doesn't matter. If I wait till later I might sell another or 3more etc.., then I can coat and bake 2 at once or more

This part is 1/4" thick and always fits inside a 12" circle, that is the size of part varies and the part is odd shaped, but a 12" tall X 12" long X 1/4" thick box always holds this part for shipping. Building an oven that small or smaller would be pretty silly for most people with normal odd parts done randomly. I do these in different colors as I sell them, so I don't know till sold what color I need. If I sell 4-12 at a time I'll bake them in the normal oven, when I sell just 1 I only need an oven size of the part.

Since I do allot of these type parts and sell them 1 at a time often, I am thinking about building a bread toaster type oven for just these parts.
I need a little extra room for clearance so the part can be inserted and taken out without damaging the raw or hot powder. 12"x12"x1" inside will fit all these parts I sell like this, 1 at a time. I plan to use NI-chrome wire for the heating elements on the 12"x12" sides, just like a bread toaster. I'll either sit the part in from the top with a frame or slide in it from one end on a frame. The part can sit on the bolt holes so I only need a smooth sliding frame and a couple pins for the part to hang on from the bolts holes.
Why would anyone ever need an oven this small or smaller? Unless doing special parts often like mine? If doing parts like these on a regular basis it would be silly to worry about making the toaster Modular since it would be needed often, AND it's so small you could just hang it on any wall anywhere when not in use until it's needed!
Making a modular oven this small would be worthless, other than 1" of space thickness it still takes the same space to store it basically!

I thought we were at first taking about modular ovens as in normal sized oven for normal parts, valve covers, wheels, bike frames maybe, etc... and the reason to be modular was when larger parts needed done at times like engines or frames, etc... and since the large parts don't need done often then no reason to waste the space permanently for an oven that large. This would make sense. I need an oven 20'x 4'x7' or so if I want to do a truck or van frame, but that will be rare I do those, probably just my own so maybe 2 or 3 will ever be done? So a modular would work well when I need it maybe once a year. Also as I plan it out, I could assemble 2 or 3 different size ovens at once from the panels for several different parts. Like do small parts in oven one, engine block in oven 2, bike frame in oven 3, all would need various bake times perhaps and I would have extra ovens as needed. Also if powders need different cure temps, say I want High temp coatings for headers in an oven, may not need same oven temps and time as for valve covers, so just set up an extra oven and run 2 at once. Many reasons modular might work well this way if built well and easy to assemble and run as needed.

Trying to build a 2"X2"x1" modular oven though would be pretty nutty! There would seldom be any reason for the smallest possible oven. Are you going to bake 1 nut for a 1/4" bolt at a time often? First wasting the powder to coat one nut at a time will cost more than the power to run an oven to bake it anyway, also if that small and using it often enough to worry about it you don't need to take it apart to store it. That would be the smallest oven I could ever think of needing unless your doing 1/4" square sheet metal parts LOL

Heck, my 12"x12"x1" inside oven may be nutty even, but if it works after built I will use it often, maybe 2-3 times a week when I only need to do 1 part like today! Why heat up the big electric stove oven on 220V when a 110V toaster type would work and use much less power.
Parts cost the same either way, so less power I use the more profit for me!

this part of what you said IS what i was talking about. to save the argument lets forget the left and right side thing. lets focus on the part that i quoted from you. that was the original focus of this thread. the big problem is what a panel needs to look like. i would prefer 1 panel design that can work anyplace in the oven, the only difference would be that some have heat elements in them, or lights, or windows, or temp probes, ect. the first goal is a panel design, later add the required equipment (i.e. heat elements/ temp probe). after a sucessfull design then we could add extras (lights/ windows/ect)

This maybe somthing To try and patent

"i already thought of making left and right panels, but what about making the smallest oven you can out of 6 panels. there would be no left and right."

OK, I guess that's what threw me into weird land there, or something similar that was said!
SORRY.

Well if your height and depth is always the same, then you will always need 2 end panels the same also. I figure my oven as 2 sides the same, left/right, these will lock all other panels in place so they don't fall over.

I am having a very bad time here, broke filter on gun yesterday, barely got parts mailed today!
3rd time to post a reply here, lost 2 when system rebooted for no reason.

I work outdoors ALLOT, WHAM, while typing the above lines just now it sounds like water fall outside the rain just hit so hard all at once! Thunder also, and the sky just lit up now too.
Odd, normally you see lighting then hear thunder! I got thunder then the bright flash!
Time to go check the tools, sheds, trucks, and other rain related items perhaps. GEE it was so nice at the little bond fire cooking hotdogs and hamburgers about 45 minutes ago !!!
I was going to hook up a light and work outside tonight for awhile on an old truck, guess not now!!!

for the last 2 weeks i have been working with a engineer on my idea. he has been in the development to production (and patent) field for about 30 yrs. he thinks my idea may have a good potential for market. my end goal is to make the product of my idea easy for any "garage powdercoater" to afford, and small shops. i also hope that it would make p.c. safer by eliminating the horror stories i have read about people trying to make a "cheap" curing source.

as we develop my idea i will keep all of you posted.
