Hi Darrel and John.
Exactly as John says, use the 2" = 50mm firebricks but stand them on the side so they make you the 4.5" = 115mm fire brick hearth thickness. 2" = 50mm would not be enough, not worthy to save number of bricks. You can stand bricks in walls as John suggested or you can lay them flat in walls too. No need to make the walls at 9" (230mm) height either, it's flexible e.g. Masterly Tail oven has 2 firebricks laying in walls and higher arch rise forming the 16" (406) vault. Picture shows Swishy oven built of 2.5" x 4.5" x 9" USA size firebricks but you can use 2" firebricks that you have even better ;o) more fragments! And how to make precise wooden template(s) for making any arches is on the CD in docs. r
