I want to find a better way to remove lips. The problem is that, as with polishing, the fibers may not be aligned correctly as we use sandpaper. They easily tilt as they slide across the paper.

Jim said today that we should try to avoid wings. If the sponge gasket is too thick, we might try electrical tape to prevent the clamps from bottoming out while fusing thin fibers.
He was concerned that if the light guides hang off the table during fusing, they could twist and cause problems. We could clamp a wide board to the table so the fibers will not hang off during fusing. We should put the black cloth from the dark box over the board, and even without a board we should cover the the area with the cloth. However, we will need to avoid snagging the end of the fiber on the cloth and possibly damaging the cladding.
Jim looked at one of my fuses from yesterday. He noticed that the line around the fuse site was faint on two sides but more pronounced on the other two. He said the fuse was incomplete somewhere, maybe at a corner. That may have been because some cladding was missing from one of the fibers. I am not sure whether he said the fuse was incomplete only at the cladding level or if some of the core was not fused either.
