I, too, was thinking of wedgeing it open when it is hot and then filling it with mortar when it cools. I suppose I will finish the curing and go from there.
Good luck.

Hi again,
I smeared some prepared (wet) firebrick cement mix into the crack just to prevent rain from entering - but would you believe it? There's a new crack now on the other side of the keystone, a fraction larger than its sibling!
It's been raining on and off all day, so I haven't worked on the oven or fired it today... but I MAY decide to saw through the remaining mortar in both cracks on either side of the keystone and replace it, nicely buttered with hi-temp mortar, once I am through the firing regime.
Cheers,
LMH
