Rocking Chair
I am trying to contact Popular Woodworking, but their ad server is slow as molassas in January. On page 48 of the October 2011 issue of Popular Woodworking, there is a picture on a rocking chair. For some unexplained reason, I want to build it. I realize I have two choices on the legs and back, steam or laminate. Given the way the arm comes in, lamination might be the easier. Either way, I am going to have to build some bending forms. My question is, the back has bends in two planes, how do you make the form? Bending in one plane is a snap, two 90 degrees to each other would not be that hard either. However, two at once, when they are ofset about 30-40 degrees is a bit more than I am familiar with. Any help greatly appreciated. Deb |

Build up several layers of MDF, cut the ess curves in it, glue one half down on a board to keep it all flat, and use the halves on either side to compress the plies into the curve you want. For steam, it might be easiest to use pegs to get your curve, or perhaps a solid bottom half and a pair of removable pegs to get that upper curve. Steam, insert the bottom half into the solid area, bending as you go, then add the next limiter peg and do the last curve the other direction, followed by the top peg to hold that curve. Was tha clear enough? Hmm, to keep from marring the piece, a curved head might be needed for the top 2 pegs, maybe with a rubber insert to pad the compression area. -- Learning to ignore things is one of the great paths to inner peace. -- Robert J.

Is this the chair you're speaking of: *http://www.popularwoodworking.com/tag/chair-design Sonny I've built quite a few rockers. Make sure your front legs are the same length and make sure the back legs are the same length.... the front doesn't have to be the same length as the back. Make sure the right side legs and rockers are a mirror image of the left side, i.e., front toe-out / back heel-in angles, relative to the center line of the seat, are the same, or the rocker may creep sideways across the floor, as you rock. Three things that make a rocker creep: 1) One leg is too long, rockers not coplanor, 2) Rocker (front toe-out/back heel-in) angles not the same, 3) If the chair is correct, the floor (unlevel, carpet pile, etc.) influences the creep.
