Sawed off cupola

<< < (8/47) > >>

vtsteam:
Here is the circle cutter assembled to the torch.

vtsteam:
And the hole it cut.

vtsteam:
I decided to make the drop door. I don't have much height to work with -- I wanted to keep the cupola low. And since the max melt is 10 lbs (I hope) the height of a ladle is probably going to be only about 6".

Anyway, It occurred to me that the door might be better as the traditional double doors seen on much larger furnaces, to keep them short when in the down position.

Also, I only had two pieces of 3/8" plate available. one was too narrow for a single door, but wide enough for a double, so I tacked my wider plate to it and put the tacks right where the circle centers would be. Then punched them.

vtsteam:
And cut them out.

vtsteam:
Cut up some water pipe for hinges and welded two sections to the doors.
