To Grind or not to grind

[woodfried]

Hi All
Well im 1 course away from closing the dome and whilst inside cleaning off mortar im looking at a few bricks over the transition that stick out here and there by 10 -15mm . Can i grind them back level or should i just leave them ?
anyone got an opinion?

Just like a flue, I believe an oven will operate optimally if it has smooth surfaces and protruding 'obstacles' are reduced as much as possible. Since you've put so much time and care into building your oven, why not tune it up while you still have the chance?

I wouldn't bother. If it is in the transition area it isn't going to be seen or create any type of problem.

Thanks for that, I suppose Im more concerned that the ground surface of the brick would be less heat resistant than the un cut fired outer surface??

Look at Les' build. Every brick facing the inside of the oven has been meticulously cut.
