Dodgy photo i know but i wanted to clear out the background so you could really see what i have done here.
at the top is the back wall, i created and cleaned that up first as i know once i get the template in it won't be possible to clean it up, its easy to do as the "fondue" /mortar dries really quickly.
Then i got 4 bars and created a brace around the side walls, the reason is the downward pressure from the weight of the arch bricks may have force the walls to fall over, the bars are simply bolted at each corner and positioned right against the walls. it proved true as i noticed the tension on the bars tighten as i started laying the arch bricks. I plan to concrete the outside over the insulation so that will secure the walls and add strength.
you can see i have the template ready and levelled, i placed newspaper over the top to make it easier to remove the template once the mortar is dried, it will make it easier to clean up the inside as well. No doubt there will need to be some pointing needed to get a good inside finish.
So its all ready to go.
