Anyone that has done more than one cut-out knows what a pain it is to try and tie the comb into frames. Yes rubber bands may be easier, but they bring there own challenges too as they can sag with heavy comb. My preferred method is to use cut-out frames which are just regular frames cut down the middle, hinged on the bottom and have embedding wire strung around the outside. You simply open them like a book, install you comb and close the frame.
I start by cutting the side bars and top bars in half on a band saw. By using split bottom frames, I don’t need to cut the bottom bars. I then assemble them like I would a normal frame. By making a loop around the bottom bars with embedding wire creates the hinge. I put one on each end. I then string 3 rows of embedding wire on the outside of each side of the frame and hold it with staples.
