Timber Processing

How Timber is Sawn

In Track 1 (Guide 10 — How Logs Become Boards), we introduced the idea that different sawing methods produce different boards. In Track 2, we learned that tangential and radial orientation determines how much a board moves. In Track 3, we saw how species properties interact with

Plain Sawn vs Quarter Sawn vs Rift Sawn

Guide 1 introduced the sawing patterns and the machines that execute them. This guide focuses entirely on the three board orientations those patterns produce: plain-sawn, quarter-sawn, and rift-sawn. We'll go deep into how each one looks, moves, performs, and when to choose it —

Timber Drying Methods

In Guide 1 we followed the log through the sawmill. In Guide 2 we examined how the three board orientations affect stability and movement. Now we follow those freshly sawn boards to the next critical stage: removing the moisture.

Kiln Drying vs Air Drying

Air drying and kiln drying are not competing ideologies. They are tools. Used well, they complement each other. Used poorly, they ruin timber.

Moisture Meters and Measuring MC

Moisture content (MC) is the number that links the timber yard, the workshop, and the finished piece. In Track 2 we covered what MC means and why it drives movement. In Track 4 Guide 3 we saw how drying methods work. This guide is the practical skill: how to measure MC properly,

Storage, Acclimation, and Handling Timber

Drying gets timber close to a target moisture content. Storage and acclimation are what keep it there — and what bring it the last few percent into line with your workshop and the final environment.

Timber Grading (Strength, Defects, and Stamps)

If you have ever looked at a piece of softwood with a stamp full of letters and numbers, or wondered why two boards of the “same” size and species are priced wildly differently, you have already met grading.

Planed vs Rough Sawn (Nominal vs Finished Sizes)

When timber leaves the sawmill it is rough, slightly oversized, and rarely perfectly straight. Most timber is then dried and machined. Every one of those steps changes the dimensions.

Timber Treatment and Protection

If you build a deck with the wrong treatment level, it can rot from the inside while still looking fine on the surface. If you treat the wrong timber for indoor furniture, you can create health, finishing, and corrosion problems you did not need.

Buying Timber (What to Check Before You Build)

Buying timber well is a skill. This guide gives a simple checklist so you can pick boards that will stay stable, machine cleanly, and fit the job.
