I've done my base and I was going to make a start on the floor today as my 32 firebricks turned up yesterday afternoon, unfortunately they turned up damaged, looks like the delivery company dropped the pallet smashing every brick, then they've re-wrapped the pallet to hide the damage.
While I'm waiting to sort out the replacements, I have a couple of questions for
david s, or indeed anyone who wants to jump in.
I'm going to build a 33" cast dome and aiming for 60mm wall thickness, what thickness do you think I should make the gallery and flue, would 40mm be about right?
Also, I'm using pumice and rockwool as my insulation, (it's free), I won't have any vermiculite but I want to do my flue like David's with the three tabs in an oversize hole packed with vermiculite to allow for expansion. Would pumice do the job? in my mind the answers no because there's no give.
I will be adding photos as I go but I want to make a bit of a start first so the posts don't drag on for months.
