I have made my own small kiln posts forever. WHY cut up a big costly =
one? Wot am I missing?
Some years back CM published a refractory recipe, I have it, but not =
here, and one mixes up a concoction of --DON'T QUOTE ME , I AM NOT =
SURE--fireclay, kaolin and grog. One then shapes it,using an extruder =
if one can. But of course there are other ways. Is that not easier and =
cheaper? Duh! The cold is freezing m' brain.

Lili, I think the original message was about salvaging broken larger posts
by cutting them down to match smaller sizes. Given what posts cost (not
very much) I certainly wouldn't do it just to be making smaller posts.

A trick I learned from my old college professor is that you can often use
glaze to "glue" broken posts back together. The break has to be more or
less straight across. (in other words, it would have to be able to be load
bearing capable without the glaze) The glaze won't impart strength to
something that would fall apart with the load on it.

As I wrote previously, we have quite a few of these 1 1/2" wide x 14"
(or longer) posts and we use maybe 6 of them on a consistent basis.
I want to cut perhaps a dozen of them down to sizes we use all the
time - 9", 12" and smaller. When we get our larger gas kiln set up, I
plan to purchase some soaps to create a more stable support for very
tall pots.

I decided to try a masonary blade in my 10" chop saw and cut the
posts that have not been fired many times. If this blade doesn't
work, then I'll give a wet/dry diamond blade a try - but I can only
find these blades to fit my circular saw and they cost lots more.
