I'm at the point in making Norm's Martha Washington's candle stand where I turned the 4 spindles and assembled the "bird cage".
The bird cage consists of basically 2 plates of cherry 4 3/4" square. Each plate has 4 holes near each corner for the spindles that goe 1/2 through the 3/4" thick cherry plate and the top plate has a hole on opposing sides to be filled with a dowel and act as a hinge for the tilting top.
I dry fitted the spindles several times and the two tops aligned beautifully producing a nice square "bird cage". Each spindle has a 3/8" turned dowel end at each end that goes into a corresponding 3/8" hole on the square plates.
When I glued them up and even with clamps...there were slight gaps at the ends of the spindles that weren't there in the dry fittings. The gaps were approximately 1/32". GRRRRR.
Do you normally allow for hydraulic pressure by making the hole larger than the dowel? If so, how much?
GRRRRRRRRRRRRRR!
