Today I welded the seams on what are now the inner and outer liners for my furnace and the ring for the lid, plus cut some plywood discs on the saw bench and rolled and taped the inner former.
I can finally see some progress towards melting some metal. I also ordered 3x25kg bags of pyrocrete 1650 formable refractory. Since I started planning this project, the supplier has moved an extra hour away from me! Serves me right for procrastinating I suppose.
your not building anything that wasn't built before Colin P. wrote his book, lot of people build furnaces the same way as what your fixing to do.
Myself I prefer to have it solid refractory, but I also understand that in some parts of the world that ceramic fiber is cheaper to use.
Check out Myfordsboy's video's on how he built his furnace, same principles double wall construction.
