Hi all,
Started the rebuild of my aluminium furnace about 2 weeks ago. In its old form it had been running for about 5 years on a home made rectory of fire cement and perlite. I recon about 200 melts of a scrap to ingots and various pours for my Gingery lathe and Shaper.
As :worthless: here are a few to get going

lining removed

lid which will retain the old home brew

and the old lining which is remarkably solid, was just the hot face that was burning away
As can be seen the outside never got hot enough to burn the paint off. Just hope the commercial refractory (1700c) works as well.
More pics of the lining process to follow.

next part of the build and the final shot with lining in place.
the refractory was made with commercial 1700c refractory with added vermiculite in the ratio of 1:1 to make it go further due to the cost, except i ran out with 3inches of the top to fill so used perlite :Doh:
