Shim mark: a pair of opposing wedges

Sawdust and Shims

A working journal of small repairs, paint and trim, written a job at a time.

What a shim actually does, and why you need more than one

Diagram of two tapered wooden shims overlapped in opposite directions between a door frame and a wall, forming a flat packing block.
Two tapered shims driven from opposite sides, making a parallel-sided packer of adjustable thickness.

A shim is a thin tapered wedge, and on its own it is nearly useless for the job most people try to do with it. Driven into a gap alone, a single shim does not fill the gap; it fills a triangle. Whatever it is holding ends up tipped by exactly the angle of the taper, which is why a door hung on single shims swings shut on its own and a shelf packed with one sits proud at the front.

A small tool kit that covers most of a first year

Diagram of a compact tool kit laid out in a row: claw hammer, tape measure, spirit level, screwdrivers, utility knife, chisel, hand saw and a combination square.
A short list of tools laid out as they are actually reached for, rather than as a catalogue.

Most first tool kits are bought as a boxed set and half of it is never touched. The tools that actually earn their place are the ones that turn up in nearly every job regardless of what the job is, and there are fewer of them than the box suggests. What follows is a short list, with the reason each one keeps reappearing.

Sharpening a chisel on sandpaper and glass

Diagram of three grades of abrasive paper stuck to a flat glass plate, with a chisel held at a fixed angle being drawn across the finest sheet.
Abrasive sheets on a flat glass plate, worked from coarse to fine in one direction.

A sharp edge is two flat surfaces meeting, and sharpening is the business of making both of them flat and making them meet cleanly. Nothing else in the process matters as much as that, which is why sharpening on abrasive paper stuck to a piece of flat glass works as well as it does. The glass supplies the flatness; the paper supplies the cut.
