A friend of mine has asked me to repair a Nichols & Stone armless Windsor dining room chair that is one of a set of eight. The back has two outside support spindles with a mortised and tenoned top curved rail. One of the support spindles broke completely off in the hole in the seat. The spindle appears to have been turned on three different centers making it far too complicated for me to reproduce with my limited lathe skills. Any suggestions on how to make a repair of this spindle that will hold together? I was thinking of drilling a hole through the spindle from the bottom and inserting a long wood screw to hold the pieces together and gluing the pieces together. What type of glue would give the best strength for this type of end grain joinery? Is this type of repair worth doing? Also due to the offset (lean) of the back figuring out how to clamp this assembly up is beyond my imagination -- any thoughts?
Your help and thoughts would be appreciated.
