Electric Heat Treating Oven

I have needed a small oven many times. But for a project
I am working on I can not continue without heat treating some
parts. I decided to make one. I thought that I would just
make the smallest one that I could just to do the parts I needed.
That soon became the wrong approach. They say you are to
learn from your mistakes so I started learning.

I thought I could get by with just nine refractory bricks and a
sheet metal cover as I was just going to harden and temper
several parts. I ordered some nichrome wire and the bricks.
I was going to use only 110 VAC so I thought I could control
the temperature with just an on-off switch. My flawed reasoning
was because I am on a fixed income.

The bricks arrived.

Before I continue I need help with the pictures.
How does one post a picture and then continue with text?

I am only able to see text. When I click preview all I see is the
text without the picture. I do not know if the picture attached
until I click post. Then I have to start another reply. Need help
with this.

Also is there a draft or save for the post so it may be edited at a later time?

I see others that post as I want to but I am confused.

Hi Steve,

What you want to do is embed your pictures. That is where they are hosted at another site and are inserted into the text with code. You can read about that here.

What you are doing now is attaching the pictures. The forum software doesn't do inline inserts with attachments.

Thanks.
See my post in this thread, second to last.

All nine bricks were damaged. After receiving pictures of the damage
the seller replaced them. I chose soft bricks as they were easier to cut
and I would have more insulation. I ordered a few more of the soft
ones and they arrived in two days.

I used the table saw with a diamond blade to cut the groove
for the wire. Opened the doors and pointed the saw to the
outside. Got a fine white abrasive dust everywhere. Trimmed
the bricks with the band saw. Had to be careful as they cut
as if they were not there. The yellow dust is from and
Osage Orange tree. The people here call it a horse apple.
Was making carving mallets.
