Guys looking for some help. Don’t know what I’m doing wrong. I made a set of eyebrows for a cub several years ago with the cores I’m using. Now trying to make another set and they will not work. As in the past I use the clear sheets from Sig. I think it is butyrate. I have tried the .015, .030, and .040 thicknesses.
The setup. Plug made from hard balsa block. I have a frame that is just a little larger then the plug. I attach the plastic to the frame with the spring paper clips. Heat the plastic over a stove burner and then swing to the plug. Problems I’m running into now is in the circled are, the plastic becomes to thin, it is like the thickness of a photo.
