We were forced to move our gas kiln! It was moved by a small crane, and
there was of necessity and reality, some shift of the bricks, and there
was in particular some movement of the arch bricks. As a result, the
movement of the arch bricks causes some frictional wearing on the brick.
Does anyone out there have experiance with similar circumstances, and if
so what did you do to repair/strengthen/or reinfoce the arch? At this
point, tearing out the arch and reconstruction of same is not a viable option.
I thank in advance all who respond.

When I have an arch out of wack, I use the same arch form which was used
to construct it, to realign it. If you didn't construct, simulate the
rise per foot and the span, build an arch support. Jack it up with car
jacks to realign the bricks, and tighten to support rods. If you don't
have support rods, put some in. I use threaded rods with a car valve
spring to insure tightness but allows expansion and contraction during
firings. It also allows for tightening the arch if it gets loose. For
specific radius for your arch you could refer to the AP Green pocket
manual if you have access to one.

Paul...
I would install a couple of "keystone" arch bricks in strategic
locations in the arch and I would increase the tension across arch with
those threaded rods which I assume are there traversing the width of the
kiln (one in the front and one in the rear).... Marshall
