George, I would likely reinforce the through bolt hole with a graphite tube. This would come from pieces of an 8 Wt fly rod that exploded in the heat of the moment, (very dramatic!). I kept a few of the pieces, they looked handy and for the memory. Likely would epoxy in the tube then glass in a bolt of the same diameter as the draw bolt using a release agent. Remove the bolt and should give a light, tight job.

Jay, that's a nice 23! At 6-10 lighter than a lot of the W23 20's.
