As the saying goes, there are three unavoidable issues in life: dying, taxes and wooden motion. And the irresistible drive of wooden motion is precisely why the body-and-panel method for stable wooden building was invented a whole bunch of years in the past.

Before that, massive panels of wooden have been principally edge glued (however not all the time) and sure had lengthy strips of steel throughout their face to attempt to maintain them collectively and from distorting. If a body was hooked up round a panel, that panel was all the time extra highly effective than its constraints.
Then some brainy particular person found out the predictability of wooden’s growth and contraction, particularly of picket panels, and got here up with a solution to accommodate it.

Wood strikes in a few completely different instructions, significantly throughout its grain. The wider the panel, the extra it expands and contracts and the extra problematic it may turn out to be when housed inside a body. By comparability, wooden expands and contracts a lot much less throughout the grain of a slim piece of wooden. That’s why what we now know as rails and stiles of cupboard doorways are created from narrower strips. Neither panels, rails nor stiles transfer to any important diploma alongside their grain, or finish-to-finish as you would possibly describe it.

The key to creating a stable door body is to create sturdy nook joints. This is finished mostly with a mortise-and-tenon joint, which has a geometry that’s exhausting to beat for this job. The mortise is a socket that captures a protruding tenon. If made correctly, tenons may have a delicate friction match of their mortises, and their shoulders will have interaction tightly in opposition to the mortised inventory. The joint turns into much more sturdy when glue and pins are added to it.
Because people are extremely artistic, there are numerous variations of body joinery, together with bridle joints, free tenons, dowels and extra. They all get the job achieved in their very own approach.
In latest years, pocket gap joinery has turn out to be one other methodology of constructing frames rapidly and virtually, however their angled screws doubtless gained’t have the lengthy-time period sturdiness of a traditional mortise-and-tenon. Even so, pocket screw joints positive are useful!

Panels are the most important and most dominant part in a body-and-panel door, however they obtain no joinery. Instead, the body-and-panel system permits the wooden panel to just about do what it does — increase and contract throughout its width. For that purpose, the panel is often captured in grooves plowed alongside the within edges of the stiles and rails so it may “float” and transfer.
Wooden door panels normally are flat or have raised middle fields, presumably with carvings. Other panel choices embody glass, mirror, steel and even ceramic.
Frame-and-panel building was one of many greatest developments within the craft of woodworking. It is so profitable that once we consider a cupboard door, it involves thoughts virtually instantly.
