 Re: Halves or thirds... that is the question
I was planning on cutting my tapered bricks into thirds from about course 7 or 8, as the Vee on the underside of each brick (over the vertical mortar joint of the course below) will eventually be greater than the 2-3mm thickness that my refractory mortar is limited to. When the gaps increase again, I was thinking of going down to quarters.
This hopefully will create smaller gaps but retain the thickness of the dome - inner diameter to outer diameter - so is a different concept to Wade's, where he has used third bricks to intentionally reduce the dome thickness.
My only concern is that it will significantly increase the number of cuts, as well as the numbers of bricks to be laid. Perhaps an easier alternative would be to do a quick pass with the disc sander to form a corresponding Vee on the underside of each brick?
What do members think?
