A few years ago I needed to resleeve a galled cylinder and left it with an automotive machine shop for repair and rebore. The machinist placed a sleeve that was about 1/8 inch longer than the cylinder, which extended by that dimension beyond the bottom, and pinned it in place. I asked why he didn't secure the sleeve in the usual manner, as described here by others, and he just scoffed at the notion. I suspect he placed a sleeve that was designed for something other than a Model A engine. The sad part is that a major crack started from the exact location of the pin and I had to junk the engine. That machine shop is no longer in business.
