I'm building a 24" deep HT oven, since I have a bunch of stainless sheet left over from a job, and the metal fab is kind of what I do most days in the shop.

There are a lot of great threads on it, (thanks, Stacy) but I'm wondering this:
While I have some $ in my pocket, I'd like to quick buy the components.

Would anyone care to share a fairly up to date "shopping list" for a 220v oven? Electronics is something I can figure out, but it works better for me once it's in hand - the diagrams look like heiroglyphics until I can lay out the components, then it's just Tab A into Slot B.

Thanks!
 
This is what I bought for my oven, the links were the first to pop up on a google search I shopped around for the best prices and free shipping

pid controler http://www.auberins.com/?main_page=index&cPath=1

50 ft 14 gauge kanthal wire http://kruegerpottery.com/repair-parts/kantal-wire/kanthal-a-1-wire-14-gauge.html

Two 1/4" x 4" stainless steel nuts bolts and washers, through the brick conecters

Two 40 amp ssr's with heat sinks

12 volt cooling fan

High temp shielded wire

I found a local source for the fire bricks the shipping is crazy on those, call a pottery shop would be your best bet to find a cheap supplier
 
Thanks so much, John!
My brain goes clunk when I look at lists of stuff and diagrams unless I have the pieces in hand, so that's a huge help.
Should be able to source bricks locally, I'm fortunate to live in the sticks right between two major cities.

John, does it matter which ssr, are they pretty standard?
Also, is the thermocouple matched to the pid? I think of a thermocouple as a switch, but maybe it's a sensor....Which PID did you get from that page, and does it matter?
 
This is the ssr that I bought which is over kill, The reason..... I read that ssr's fail in the on position due to heat build up, so I went big with the heat sink and the ssr hopping to minimize any fire hazard

This is the pid I chose because it has the ramp/soak features and the best price

The thermocouple is a sensor that will tell the pid to switch the ssr on and off, this is the thermocouple that I picked

EDIT I put the wrong thermocouple up the first time this is the one you want

I accidentally put up the wrong thermocouple the first time the one listed now is the correct model, hopefully I caught that mistake before you made your order
 
Thanks! Kind of you to take the time to share links.

I wired my house and shop and it all passed, so it'll all make sense as soon as I have the parts here- it's just that all those extra trips to the store or returned packages because I have no actual idea what to order when someone says "A THERMOCOUPLE' and there are seventy five different ones listed.
