shim

The gaps were supposed to be filled by Boeing mechanics at final assembly with precisely measured pieces of material called shims.

My job was to cut long, tapered wood shims on one side and add a cement-stucco finish on the other side of the foundation.

Of all the work Schuermann did on the guitar — including steam and heat treatment of the bridge and adding a removable shim for stability — the neck reset was the biggest undertaking.

Often, the city’s answer is a temporary bevel and shim fix — either grinding down edges on cracked sidewalks or adding a small amount of asphalt to bridge the gaps.

Such gaps are typically plugged using a filler known as a shim.
