Good luck with your chimney, Steve.
The cardboard form makers will be very disappointed if
you figure out a way to re-use the forms. It always
bugged me to trash them after one use.
I'm afraid you might have trouble removing the forms
because of the seams in the forms.
When I cast my chimney, the inner form became completely
wet and lost its rigidity. This is because the outside is not
intended to be used in direct contact with concrete, and
thus is not coated with a heavy layer of plastic as is the
inside of the forms.
Be sure to let us know how your technique works and how
your chimney turns out.

| Greetings,
| Even though I should directly send this to David, I thought I would share
it
| withthe rest of Clay Art, see David Hendley's article on casting a
chimney,
| Ceramics Monthly Feb 2001. I decided to give this a shot, making my own
| chimney, that is. Like him, I also have alot of broken brick and
fireclay.
|
| Here are the changes I plan to make in constructing the new chimney;
| Instead of wrapping the cast sections with sheet metal after they're made,
| I'm going to line the inside of the outer tube with the metal. I picked
up
| a roll of 20 inch x 25 foot roof flashing from a local hardware store.
I'm
| also going to use plastic sheeting to make the tubes reusable.
|
| I know that trying to explain all of this might sound a little confusing,
| especially in written form. But I'm taking David's idea and changing it
| alittle. I want to see if I can make the forms reusable as well as saving
a
| step. So far, the total cost is about a $100, this includes the cardboard
| tubes(2 ea of 8 inch and 12 inch all 4 feet long) , portland cement and
the
| metal flashing. If anyone is interested, I'll post my progress and how
this
| whole thing turned out. And if you, David, might have any suggestions
just
| let me know.
