I've had very good luck with first penetrating epoxy 30 years ago and thin C/A in more recent years. All responses have agreed with my experiences. My keys to success have been thorough cleaning of top of plate webbing, injecting droplet by droplet with hypodermic or plastic pipette with very thin tip [stew-mac.com], ALWAYS removing action first [as below!] And - spritzing underside of wrest plank just in case - also staying away from plate screw holes. The combination of one of these adhesives combined with the structure of hardwood has been a longer enduring repair than new wood for both wrest planks and bridge caps in many cases in my experience. Used to use a lot of Titebond, now mostly hot hide and some C/A for hardwood that I can never imagine anyone wanting to separate in the future.
