It isn't fun and I would do it only with a circular saw I bought at a pawn
shop . . . I did it with a cheap small plastic circular saw with a cut off
wheel on it. It makes a lot of dust . . . you can cut the dust by using a
little water . . . at the danger of getting electrocuted. For a small sum
you can rent a tile cutter from a floor shop that might work easier.

It is because the other dimensions of the brick are the same as the 2.5"
bricks (9" x 4.5"). When they make the angle cuts to the outside corners on
the 9" face it makes the brick protrude into the kiln a half an inch.

Dick is correct about the 2 1/2" / 3" wall thickness. Paragon kilns
also vary inside depending on brick wall thickness.
Even though you will have to replace your shelves, I would
definitely go with 3" walls. The thicker bricks have a little more
insulation, and they are also sturdier than 2 1/2" bricks. We still
make 2 1/2" wall kilns for low-fire ware such as china painting,
and for people who want rapid cooling and rapid kiln load
turn-around time.
Sincerely,
Arnold Howard

You can use a masonry blade on a circular saw to cut your shelves down.
Better yet, find a tile setter with a diamond wet saw to cut them down -
less dust.
If you were closer, I'd have you fixed up in no time.
Good luck,
Roger

Hi Barb,
Some suppliers will cut those shelves to size for you.

A while back, probably a year or two ago, we had a number of comments on
this list regarding the fast cooling of electric kilns and wouldn't it be
nice if the kiln manufacturers could build something with a little more
insulation? So perhaps someone was actually listening.
Now, why did they take it out of the inside instead of the outside? Look at
your kiln and notice how many things would have to change if the outside got
larger - each piece of the shell would have to be larger, the base would
grow, the lid would grow, placement of parts would be different. None of
these things is an engineering nightmare, yet each design change requires
new drawings, a recheck of error tolerances, possible retooling, and
probably worst of all, retesting. If a UL certification is required, it may
have to go through a recertification.
All of these would add an incremental cost to producing the new kiln,
possibly making the price for that extra half inch of insulation beyond what
anyone would be willing to pay for it. Good engineering is a monument to
compromise. I believe that L&L looked at the design choices and produced
what they felt would serve the pottery community the best at the most
affordable price. Sometimes the choices aren't easy. If they find that they
have underestimated the importance of shelf size and no one buys their new
kiln, then they may have to change the design.
As a gas kiln person, I find it rather odd that your shelves are so tight to
the sides of your kiln that you could not tolerate the loss of an interior
inch. You could never do this in a gas kiln. It would choke.
But tight shelf to wall spacing doesn't seem to me as though it would be a
good idea in electrics, either. By placing the edges of the shelves close to
the walls you are effectively making separate heat zones for each shelf, as
there is little convection that can occur. Even with an electric, I would
think that you would want some convection to help even out the heat.
Otherwise a more densely packed shelf will be significantly cooler than a
loosely packed shelf unless you typically do very slow firings. And do you
really want to set something that close to the elements that the shelf must
extend out to the wall?
Finally, you don't really need new shelves. Rent a wet saw and cut down the
shelves to a size that will fit.

Seattle Pottery Supply has been building kilns with added insulation on =
the outside for years. No change to internal dimensions.=20
Definitely worth considering, or even having one built to your specs if =
there's not a stock one..=20
