Quick test run in the back yard. Lot of leaks from assembling it dry but it ran OK.
Will slide it into the bell inside tomorrow.
No glass yet so just a piece of dry wall against the opening haha.

Also welded a lid on the bell.

This morning I made the decision to remove a lot of mass from the fire box. I've split all bricks which leaves plenty of room to line the inside of the metal box with ceramic board to get the thing up to temp much much faster.
I believe I saw Satamax use this technique in a build a while ago.

Huh, may be, but it wasn't ceramic board, that's for sure!

What was it then? I think I might just stuff super wool down the sides actually, since I already have it

Huh, don't know! Can't remember. I line fireboxes with rockwool, vermiculite, perlite, or a mix of the two. Or air entrained concrete also.

Haha fair enough.
I have small concerns of my 5 minute riser causing a restriction. I had to slide a 6" flue pipe inside and roll it around to crush the super wool a bit to increase the internal diameter. Managed to get it to about 175.
If it causes problems I have enough brick to split and build a brick riser to wrap in super wool.
I hope it's OK though because I have plans to build a heater for a hot tub with those bricks next!

Benen, i reply here, easier for me.

Keep your fivce minute riser, but use 1 inch superwool.  That will be the easier solution.

About the plunger tube.  Get your sketchup out, i understand fcuk all!

If I use 1 inch super wool then the diameter is much too large in the riser.
Haha yes, I'll use sketch up to draw the bell in place to show what I mean.

Doesn't mater if the heat riser is too large.

Is that right? Damn. I had 1" in there and took it out.

Here are the sketch up files.
Basically it's passing through a wall in the dining room. The bulk of the heater is in a hallway but there is plenty of venting space for air to get to the living area. Will probably use heat transfer ducts in the ceiling to move the heat to other areas of the house.

Perfect. I just had concerns regarding proximity of the flue to the barrel and the length of the bell. Thanks for easing my mind.

Picked up the glass for the door today. All that's left to do is the cowl and dektite on the roof, get the glass in the door and drop the bell over the riser.
Was hoping to have it firing tonight but I can't lift the bell alone.

It's alive! Still drying the bell but burning smokeless and the house rose from 10c to 20c quite quickly. The other side where the bell is got up to 30c quickly and I can't touch the top of the bench. Water steams off immediately.
Need some shielding behind the barrel urgently as the wall is getting very hot!
Couldn't be more pleased!
