This is my modified version of the half cast method of mounting fish using Tom Sexton Fish Filler (WASCO) and a plaster impression of the fish. It's quick, it's easy, no glue needed, no sewing or stapling of the back seam, no need to carve a body or order a mannikin, and best of all the results are anatomically correct. Using this method I can't imagine ever trying to find a mannikin that will fit this category of fish; that varies tremendously in anatomy from season to season, or from one body of water to another. And there is no test fitting needed, which can put stress on a crappie skin. Plaster impression made of fish before skinning. Simply poured plaster on a piece of garbage bag or newspaper once it is thick enough to provide the required depth and laid the unskinned fish in it to the midline. Let the plaster set up and remove and rinse the fish and skin out. Be aware the show side faces down. The next day or several hours later the skinned out fish skin is laid into its original postion with fins lined up etc. Note the white clay where the tail meets the body. The clay takes longer to set and one can use it to create a smooth tail to body transition. Using Tom Sexton Fish Filler the body is partially filled and a piece of precut plywood is put into position at approximately the center of the body to be covered with more filler. It's important the filler has the consistency of wet play dough. Fish is overfilled with the fish filler and the excess is pushed out the back seam. This is very important to prevent air bubbles or depressions. Fish almost completely filled with a plastic spatula in view. This tool can be used over and over again for mixing the filler with water by simply flexing off the filler once it sets. Same goes for a gallon plastic ice cream bucket that I use to mix the filler. Note one step is not show! Once the filler starts to firm up I remove the fish from the filler, turn the fish over, and prop it into the postion I want with paper towels underneath the body. This gives a curve to the body if you wish. You can even do reverse curves with this method very easily. I wet the fins with spray bottle of water periodically, and wait for the filler to become hard which is within 20 minutes or so. Also if you want an open mouth fish it's important you pack paper toweling into the mouth of the fish before the filler sets up. The filler has set up and after predrilling a hole into the back of the fish and plywood block, a piece of furrowing stripping is screwed into the back of the fish with a drywall screw for hanging. The fish all carded and hanging up to dry.
