As changes in the economics of the industry occurred, developments in powered machinery began that had an impact on both preparing and assembling. In 1805, Brunel took out a patent for large circular saws particularly associated with veneer cuttingand in 1807 developed the saw further in association with block-making machinery. However, one of the most important developments was not on this scale at all. The small circular saw of up to seven inches diameter, often operated by a treadle, was one of the keys to the success of small-scale furniture makers. This saw enabled makers of cheap furniture to square up, mitre and rabbet cleanly, accurately, and quickly, allowing the frames of cheap carcase work to be simply rebated and nailed. This method of rebating, using a circular saw, was particularly useful for drawer-making which was traditionally a place for using dovetail joints. The advantage of this cheap method was that a dozen drawers could be made in the time it took to merge joint just one.
History behind the chair-
Thomas Lee was the first to build and found the Adirondack Chair. He made it simply for relaxation for his family members. It was a great success and all his family members really liked the chair. He decided he would show it to a carpenter named Harry Bunnell. Bunnell really liked Lee’s chair and decided that he should start making them more than just for family but for a profit. Without Lee’s knowledge he patented the chair idea and began making his own Adirondack chairs with the same design as Lee’s. It was a big hit around the region and soon in the history of furniture. Originally it was named the Westport chair but then later on it was renamed the Adirondack Chair. Bunnell's Adirondack chairs were made of hemlock, painted in either dark brown or green, and signed by the carpenter himself. Today, Bunnell's original chairs come at a hefty price, about $1,200 each and he sold them for only $4.00.
