the shaker chair
there is a fantastic poster included at the back of this book which charts the various differences in design that can be attributed to the separate communities
bill eastwood having made shaker chairs in which he strenthened the joints between the back legs and the side rails with iron rods was amused to find the x-ray of a pommel that had been reinforced in that way
i now agree with his reasoning after learning that the shakers had rules that emphasised the care that members should take with all the communities possessions. hence there were rules for how to move your feet when turning at the top of the stairs in order to avoid wearing out the carpet at that point
having made a commode i appreciated this shaker example
