BOLD, After reviewing the info and your posts from page 1 showing with the green arrows and viewing the "COOKING ANAMORPHIC LENS" video and other videos, It seems to me that the idea here is trying to get the two lens, front and rear closer to achieve closer focusing. I think the images with the green arrows tells me that we do not have to cut the B&L in half like Cooking Anamorphic's video, instead looks like we can modify the B&L by cutting maybe an inch off more or less the front outer element housing where in your photo shows the gap between the inner barrow and outer barrow with green arrow and cutting the same off the bottom of the inner barrow that holds the front glass so there is room to push the front glass further down, last thing to trim down would be the area with the two side screws are so everything can be reassembled. Will anyhow I think this is what I'm going to try to do and will also try to document back here with photos of the project. Oh and one more thing, this looks like it can be done with a pipe cutter, clean with no mess like a saw
