ADB Staked Armchair
STAKED ARMCHAIR Chapter 2 Armbows are diff icult creatures. here’s something about building an armchair that tips the mental scales for many woodworkers. Making a stool is easy – it’s a board withT legs. OK, now take your stool and add a backrest to it. Congrats – you’ve made a backstool or perhaps a side chair. But once you add arms to that backstool you have committed a serious act of geometry. You’ve made an armchair, and that is hard-core angle business. Yes, armchairs are a little more complicated to build than stools or side chairs. But the geometry for the arms works the same way as it does for the legs or the spindles for the backrest. There are sightlines and re- sultant angles (if you need them). In fact, I would argue that adding arms to a chair simplifies the geometry because you have two points – the arm and the seat – to use to gauge the angle of your drill bit. When you drill legs, for example, you are alone in space. OK, I’m getting ahead of myself here. The key point is that arms are no big deal. So let’s talk about arms and how they should touch your back and your (surprise) arms. Staked Armchair all sticks are on 2-3/4" centers 2-3/4" 4-1/2" 3-1/2" 65° 38° 2-1/2" 2-1/2" CHAPTER II 27 Here. This is where I like the back of the armbow to go. Its inside edge lines up with the outside edge of the seat. -

The wood must be plasticized. Although wood can be plasticized chemically or even by microwaves when in a green state, the most convenient way to plasticize wood is with steam. Wood cells are held together by a naturally occurring substance in the wood called lignin. Imagine the wood fi bers to be a bundle of rods with the space between them fi lled with lignin. The strength of this lignin bond between the rods can be decreased by subjecting For example, a straight piece of wood 1" thick and 18" the wood to steam. With unpressurized steam at 212° long bent to 90° around a 4" radius will remain 18" Fahrenheit, steaming for one hour per inch of thickness along the outside (immediately next to the strap), but (regardless of the width) will soften the bond enough for will have the inside dimension reduced to almost 16". bending. Substantial oversteaming may cause the wood Nearly two inches have virtually disappeared through to wrinkle on the concave face as the bend progresses. compression along the inside face! 2. Only air-dried wood of an appropriate species Strap should be used. Blank Kiln-dried wood must not be used; the lignin in the wood has been permanently set during the hot, dry 18" kilning process. -
