Now, find a suitable material for the shims. ~~I use margarine~~ tub lids~~; Jeb has used~~ milk bottles~~. Anything~~ similar should work pretty well. Cut out 12 rectangles, each roughly 5/8" x 1 1/8". ~~When I first did it~~, ~~I used~~ two in each crevice, for a total of 24. ~~Since then, some~~ slack ~~has~~ come back~~, so I added~~ 12 more, for a total of 36, or 3 at each crevice.

Now, find a suitable material for the shims. Margarine tub lids, milk bottles, or anything similar should work pretty well. Cut out 12 rectangles, each roughly 5/8" x 1 1/8". Depending on how much slack you have, start out with one or (usually) two shims in each crevice, for a total of 24. Some slack may come back later; then you can add 12 more, for a total of 36, or 3 at each crevice.
