Squared & drilled dowell holes then flushed with acetone and used a syringe to insert Titebond water proof wood glue. Used three clamps to bind things up then glued & drove home the pegs and let it sit for about 24 hours unclamped cut the dowels flush a dab of stain and here you have it. Hopefully good enough to prevent further damage upon firing.
Thanks to all for all the input.
