Hello!
I am planning to build a baking oven and intend to construct an arch for the firebox area.
I am thinking of making the arch using a fiberboard sheet that I bend to support the bricks. Now my question is if anyone has experience with this method of building an arch. It might be considered a "shortcut" compared to chiseling the stone and fitting the stones into the arch, but it seems like a simple and effective method if one hasn't built arches before.
For example, how do I remove the support board (fiberboard) under the bricks once the mortar has set without damaging the construction? Does there need to be a gap between the brick and the board used for support, or can it rest directly on the board?
Grateful for any answers!

it's not a cheat option that's how you do it...the last one or those in the middle you cut/split into wedges...the masonite must lie on something for it to get support, such as boards that are cut according to the size of the arch...otherwise, you just let it stay there until you start to fire...masonite burns, right 
and yes, the stones should lie directly against the masonite otherwise it doesn't do any good.
