Here's a shot of the inside of the oven dome; we removed the ball this morning and it all stayed in place :-)
Next up is the thermal blanket layer. This is made of fibreglass and is thoroughly nasty. You need a breathing mask to work with this stuff. We had two rolls of it, to layer on top of the dome. We cut slits in so that it would lie flat.
Here's the dome completely covered in the fibreglass sheeting. We took some wire and tied it down, using turnbuckles to tension it. You can also see here that Alan has cut away some of the heat stop layer on the bottom, just tidying up the corners.
And here's a view from the front. Alan has also cleaned up the bricks at the front of the tunnel, using Hydrochloric (muriatic) acid to take the cement off them. He's also using the old former as a temporary door; he drilled holes and installed tie wraps into the holes as handles - it should be enough to keep the worst of the crap out. We are, however, covering the whole lot in a tarpaulin until the stucco layer is in place, since we must not allow the fibreglass to get wet.
