Oh yeah I wanted to get it covered up. I got all suited up to cut it

I was able to get some of the steel cut and installed this week. I also got the cfb all covered up.

Thanks James no those are heavy fire brick. I am hoping to get to a pottery store Friday that is a couple of hours away. They have the brick and board I need to keep going.
Trev is great  he pointed that out as well and gave me the size I need for the afterburner.

I have left the uprights long until I sort outmy heights. I already messed up the finished height of the firebox but I am going forward as is.

Still making progress

Im pretty happyso far....I still need to do the bottom, the top,and the two angled pieces.
I made those molds up today.

I am still trying to figure out my air intakes.
Is the P channel a good option for secondary air intake on these stoves

Well I got the sides and back section of the firebox poured today. This mixer is a cement mixer I think it may have been better with a morter mixer The refractory wanted to roll into balls more than mix but I was able totake a large wooden "paddle" and help out with the mixing.
Looking forward to pulling the forms tomorrow.

I was thinking of putting these in the oven for a few hours tomorrow...good idea?

I used wax for 20 years until I discovered WD40 oil. Add sparingly and wipe any excess with a cloth.

Thanks Peter I have lots of that here

The problem with oils is that it contaminates  the cement, wax is better.
Tin foil works as does cling film but neither are anywhere as good  as plastic lined mold.
Are you adding fibres or steel pins to your mix?

Hey James yeah wondered about getting myself into a pickle if I used old oil, figured I might get some weird chemical reaction
I have used marine spar varnish before for concrete and that seemed to work good.

I dug out my old Positive Air unit I use to use for painting cars I figure I will wear it ....seems this stuff is a bit nasty

I am not adding anything to the mix  I figured its just a box no structural component to it.

Are there any rules to this forum I should be aware of.
