Question by sunshyne77177: How can we create an arched brick fireplace without the bricks falling out of the arch before the mortar sets?
We want to build an arched brick enclosure for our woodstove but can’t figure out how the arch sits in place until dried. It seems that the bricks would just slide off while waiting to dry?! Help!

It’s easy. Build a wood form out of 1/2″ plywood cut into the shape of the arch. Use two plywood arches about 5″ apart, front to back, for the bricks to rest on while the mortar sets. Position this form in the exact spot where you want the arch and secure it so it can’t move. Then simply line up the brick along the top of the plywood form and mortar them together. Keep the mortar wet and covered in plastic so it does not dry out for at least 3 days. Then disassemble the plywood and the brick arch will stand on its own. You cannot do this without a temporary form.
