There is nothing …
There is nothing inside the tube. There are air holes at the bottom as you sugest and a nozzel to control gas flow. The burner will not light outside the furnace unless a cone is added to the tip. Gas pressure is 2 bar. I can let you have a drawing of my design if you PM me your email.

Thank you very much …
Thank you very much for these videos! These are very informative and helpful.
I’m planning my own furnace and I’m having little trouble in figuring out the burner. I have a similar burner than what you show in this video. Is your necktube just a straight pipe apart from the connection part and the air holes close to the handle or are there some inner shapes and/or nozzles inside the necktube that do not show on the video?

Thanks for the info …
Thanks for the info on the paint tin. Sorry, another question. I am making up a burner to screw on the end of my Bullfinch torch. Is your burner just a piece of steel tube with air holes at the cold end, or is there a jet in it somewhere? Thanks

The former is a …
The former is a plastic paint “tin”. It was a 5 ltr size with 10 or 20 % free. So its a bit taller than the regular size. I don’t remember using a release agent, the refractor y shinks a little when it dries so it came out without any problems.

Hi, excellent …
Hi, excellent videos and casting finish. a great help for the home foundry.
It looks as though you have used a paint tin for the internal former. Did you cut the bottom off in order to get it out and did you put any form of release on it? Thanks.

You need to build …
You need to build up the temperature slowly to prevent cracking. I put a light bulb inside for a few days, Then put it in the kitchen oven on full and finaly used the furnace burner on gentle heat for a while. You can see by the colour when its dry.
Lid made same way as furnace. not essential but keeps the heat in a bit.

How long do you bake the furnace and at what temp? How did you make the lid and why? Thanks!

I don’t remember …
I don’t remember that there was any problem removing the tube. Just twist and pull.
The idea of the T shape was to make an outlet for the metal to escape if the crucible breaks. If I made another I would incease the size of the hole from 3/4 to 1 1/2 as when my crucible broke the metal solidified in the hole!!

Great I found it …
Great I found it after I posted my last comment. Questions though,Was the filler tube hard to remove where the neck tube for the propane burner is located? What was the T shape PVC fitting for on the underside before you added the mix?
