Planing & Thicknessing Timber, getting wood Flat Square and True

Time to power up your Woodworking machinery and make some shavings

Now the wood has acclimatized it’s ready to plane to the finished sizes. Some of the pieces will have dried and shrunk evenly. Some will have twisted, bowed, bent or cupped. Enough spare should have been left on the rough cut pieces for these problems can be sawn and planed out.

First check to see if there are any problems to rectify, here’s what to look out for:

You can spot most of these visually by sighting down the end.

Slight winding (twist) can be tricky to spot so use a stick at either end to amplify the distortion.

A straight edge can be used on bowing, springing (bend) and cupping.

The diamond distortion has to be checked with a square.

Just to add to the fun you can have any combination of these distortions in a single piece.

Don’t despair! The methods I use, correct the problems without too much trouble. My Planer Thicknesses (Jointer in the US) is only small and lightweight but it does the job.

Maybe I should have bought a better one however I can still get excellent results when used in tandem with my table saw (or band saw).
