All of my furnace was custom made. The body came from an old sauce drum (240 L), the burner tube was some mangled steel that was a parking barrier at the airport (a driver had hit it). The burner itself was some old Galv 3/4" plumbing pipe, whilst the copper gas pipe was recycled from an air conditioner. The only parts i actually purchased was the 1/2" to 3/4" BSP nipple for the burner, and I purchased the letter drill for the burner. Total cost. about $50 including the cement and perlite.
I do have a cement mixer already. Its been so handy for many things - my wife uses it for batches of potting soil. I used it last to tumble rust off some anchor chains. Now this...
Is that propane burner on your foundry store bought, or DIY?
I'm looking at a nice late '40s Atlas 10x24 lathe to jump-start my machine projects. The Gingery books contain many fine ideas I'll use - foundry, casting, tooling, etc, but I want to get to making boat parts & other projects ASAP.
That burn was using LPG which is the easiest and cleanest of the fuels, though not the cheapest.
The refractory was made from a cement / sand / perlite mix. I would strongly suggest that you beg / borrow or steal a cement mixer to mix it, as hand mixing was very unpleasant.

Thanks for the vid - very nice!
Please tell, what sort of foundry burner is that, and what fuel? Charcoal may be OK, but it looks like gas or oil rocks for regular use...
Just ordered the Gingery 7-book set and am putting together my bill of materials for green sand and foundry rectory.
