After letting the refractory set up for about a day, I
removed the forms. That was an adventure in of itself. It took me
three hours to get the forms completely out of the lid and body.
Remember on the last page I said that I made a mistake with the bottom
centering dowel.
-
The top of the form came out pretty easy, but that is
where easy stopped. I could not pound the dowel out with the hammer. I
tried using a 1/2" rod and the hammer, but merely beat a
1/2" hole down the center of the 3/4" dowel. I ended up
drilling the dowel out with a 3/4" drill bit from the bottom.
-
The next part was that the bottom forms would not
release. I had planned ahead a little and painted the particle board
circles with several coats of spray paint to seal them from absorbing
the cement. However that did not seem to help at all. They would not
budge. I ended up using a 24" long 1/2" drill bit to drill
dozens of holes in the particle board. I then used a 5/16" allen
wrench in the holes and pryed the particle board into small pieces.
Since the forms where 3 layers thick, I had to repeat this three
times.
-
Upon removing the side forms which were made with tin
flashing material nailed to the top and bottom circles, I found voids
in the cement all the way around about two-thirds of the way up the
side. Apparently when I dumped in a new batch, I did not get the air
pockets out. A consequence of starting this at 10:00 at night and
finishing up after midnight.
