I was commissioned by Wonderland Cave in Nemo South Dakota to build a display stand for a 60 million year-old Dogtooth Stalagmite. There were a lot of factors to take into consideration, since it was being installed in a busy visitor’s center and it weighs 450 pounds the number one consideration was safety. In order to keep it from tipping over and to keep someone trying to pull it over I decided to set the stalagmite at a 35 degree angle.
Since the back of the stalagmite is very rough and lumpy I decided to make a mold out of concrete for the stalagmite to fit into. I then mounted the concrete into the display stand to support the stalagmite.
The stand has a ¾ inch thick sheet of solid core plywood for the base, I put in 2×4 framework and 2×8 pieces to hold the weight of the stalagmite. I supported the concrete form with four 2×4s to keep it solid with the weight on it. I covered the stand with ¾ inch MDF glued and screwed to the frame. I covered the MDF with ¼ inch Birch plywood, sanded it down, put on three coats of dark oak stain, and finished it off with four coats of furniture paste wax.
It took two guys to put the stand in place and four guys to move the stalagmite into position. They had to creep the stalagmite along because it was too heavy for the four of them to pick up and place it in on movement.
Everyone seems happy with the finished product, had the local newspaper there documenting the process, should be an article highlighting the stalagmite and my workshop coming out in a couple of days. Usually I can say “well, things are going” today I can say “things are going well”
