 Carefully align the Play-doh bead to the outside of the edge/tip mark. The bead must be of greater height than the blade thickness in order to accommodate the epoxy. |
 Mix epoxy and desired filler to a mayonnaise consistency. I use a mixture of silica and sanding dust. Pour the mixture into the space between the blade and Play-doh carefully working about bubbles. |
 Cure until solid then remove Play-doh and roughly shape with rasp. Let cure until hard then finish shaping by sanding. |
