Rebuilding my oven

[Randy3000]

So i built my heat treating oven a while back and it has worked great but a few issues i need to address.

First is i need to weld a new frame now that i am better at welding. I also need to paint the frame so it doesnt get all rusty.

Aside from that, i have trouble with the coil staples coming out. They went a little over an inch deep and it just isnt enough to hold them. I also feel that since the bricks are just stacked in place and can move around that that may cause staples to work loose when i move the oven and the bricks jostle a bit.

So what is a good refactory cement to use that comes in a small, reasonably priced, quantity? Also, just how deep should the staples be? Is there a better system of keeping the coil from going all wonky than using staples?

I am about to build my oven and had the same questions about the staples. Are they needed if you cut angled grooves deep enough into the bricks that allow the elements to sit nestled in? Thats the approach I am want to go. Staples will be a last resort.

Those coils get wonky when they heat and cool, i know just a deep shelf isnt enough!

I have used Rutland fireplace caulking that comes in a tube just lay down a bead and use your finger to smooth it out like regular caulking. As for pins I used straight pins at a steep angle.

I use a pinch of Vesuvius 3000 about the size of a pea and smear it across the junction to the heating element and the lower edge of the channel it lies in. I do this about every 6 to 8" of coil length. Like Randy said the elements get wonky.
Good luck
