I am going to have to rebuild my electric kiln or buy a new one which does
go against my tightwad grain. I will need a lot of grooved bricks and am
wondering if anyone has experience cutting the element grooves themselves.
Will a carbide tipped router blade survive the firebrick or is there anothe=

way. I have a couple of almost new blank rings that I no longer use which
could be utilized if grooves can be cut.

I visited L&L kiln a few years back and watched them building kilns.
They did have some kind of jig/exhaust/router system set up.
Don't see why a router blade wouldn't work for you project.
Finding the shape might be the issue.
Do this outside and wear good respirator.

Paul, here is a video that shows how Paragon grooves the
bricks:

The most interesting part of the video is the beginning,
which covers the cementing of lids and bottoms. It is an art
form, as you will see.
Are you sure you need new bricks, though? Unless a kiln has
been overfired or flooded, even broken bricks still insulate
well. Most brick damage that I've seen, other than overfired
bricks, has been cosmetic only.

Arnold,
Thank you for the link, it was informative and gives some ideas for
thought. I am afraid I do need the bricks since the edges that hold the
elements in place have broken off in many areas. The kiln is over 20 years
old and I added an extra fired section ( total 36 inches) which I am sure
has put additional strain on the bricks. The kiln has done a lot of
electric Raku which probably hasn't helped much either.
I am still contemplating buying a new kiln and then rewiring to add another
section which could easily be made from my old kiln. The real decision is
whether the bricks that still look good in my kiln have taken enough abuse
that they won't really hold up after rebuild and that I would be facing
another problem in a few more years.
I also have a full set of elements on hand so that cost is not a factor.
What to do?
Paul
