An old tip for leveling ZCI I first saw on this newsgroup,
but can't remember who to credit: Just put a blob of hot-melt
glue at the correct spots on the bottom of the insert, press down
into saw so it's just above flush, then hit the blobs with a block
plane or sandpaper if necessary.


Might have been me as I did that many years ago. However I sanded the blobs
until the fit was correct. I later went with putting screws on the bottom.
