What you need to do is prepare what I call "string frames."Get some light string like kite string or even fishing line.Lay a frame flat on a hard surface and staple the string end on the top bar upper corner,then at a slight angle down to the bottom bar. Repeat. Work your way in a zig zag pattern across the frame. Flipped over,this gives you a grid to lay the comb on.You can then repeat on the other side or use rubber bands.I use another frame as a template to cut the comb to the proper height.
