I have poured many baits over the years and the learning curve was tough.I have tried everything.The best method I have come up with so far is as follows:A two piece mold is the easiest to make.You may use any type of wood for the model.Take two pieces same size including thickness. Paint one side of each piece black (not heavy). Spot glue the painted painted sides together,this will give you a good center line to carve your model from? Both halves need to be as close to the
same thickness as possible when finished.
Each outside must be sealed good to fill all
Pores in the wood or they will show up in
the mold and on your bait. Then wax both halves before you separate
I use a little super glue gel to glue them together, about three places.
Separation is easy, use a very sharp, thin blade knife. Nothing is hurt
even if it tears a little wood from the inside it doesn't matter. Stay on the centerline, you will be able to seen it.
