Windsor Chair spindle tenon issue
A few months ago I began a fairly ambitious project for me - a Windsor rocking chair from plans fom Peter Galbert. I am using walnut riven from a tree someone gave to me for all of the spindles, legs, stretchers, and arms.
I encountered a problem recently which is that I sized the tenons with a draw knife, and one of them ended up a little undersized for the mortise it's supposed to fit into! I am out of walnut from that tree now, and really don't want to remake the spindle!
So I'm looking for suggestions on how to tighten up this joint. I considered inserting some small wedges into the gap during glue up, maybe? Or also maybe "fox" wedging the joint.
Can these work? Anybody attempted a similar fix? Maybe I can just wrap a plane shaving around the tenon?
I've attached an image of the chair and the offending joint.
