New furnace build

[b4dyc]

Hi all
Thanks for taking time to respond
I was a diesel mechanic for a few years when I was a youngster and always had to solder and weld tanks up. I never had a single problem with gas soldering tanks I think the water fully purging the tank that was taught to me has always removed the gases remaining in any tank. But if you do not feel happy doing this, then don`t!

Anyways, had a bit of shop time today as it was raining, again.
First I drilled the hole for the burner (going to be gas powered) I used one of those metal hole saws for the job.



Next up was filling that lid with perlite/fire clay.
Mixed both together dry and then added water to it so it bound together


Then filled the lid and compacted and smoothed the lid off. I left a hole in the top for a vent

Same process for the furnace body. Needed to put a tub in there so i could ram the mixture down.

I also left a hole in the bottom for a safety measure if the crucible splits etc. It will be the weak link. Also shaped the hole for the burner

Put them in waste bags so that they dont dry out too quick.
