Sets like the Philco model 45 'butterfly' require a 1/4" nut driver to adjust the compression style trimmers in the IF cans, but the clearance into the top of the cans is very, very narrow. I got away with a recent alingment on my model 45 by doing this melt-forming trick with a very thin piece of plastic tubing, but I had to cut off and remake the nut-end after each can, as the plastic didn't hold up well in use. Basically, it was a single-use tool. Sombody needs to make a really high quality, thin-walled example of this tool from a material that's got some durability.
