Hey Ric My experience parallels Jon's. I always use a spritz of accelerator in a loose wood joint. Otherwise no glue remains in the joint, it all soaks into the wood. It is something of a mystery as to why it ended up looser. I do the same for bridge pins, usually. I'll lightly spray and wait for a minute or two before applying CA. This delay will also delay the glue set up, giving it a little more soak in time and preventing the bubble build up on top of the bridge.

Thanks... makes sense when you first stop to think of it. I will remember. On the other hand I thought if you applied enough it would soak into the wood only so far and then fill in the gap. If it doesnt do this really.... then what about <<fillining>> bridge pin holes ? I understood folks were just using CA straight up for that application. For that matter.... what about tuning pins ? What I dont understand about the shank / hammer head experience tho is that the hammer was actually significantly looser when I came back yesterday... way more wobbly. Almost like the shank just plain shrunk...sounds unlikely but thats the feeling I got. That despite a slight buildup of glaze on the inside of the hole in the hammer. Cheers RicB John Page writes: The CA wicked away from the joint via the grain. Had you given it a shot of accelerator first the CA would have remained in the joint. This method has to be done for reinforcing any joint, grand jack mortices, wippen support posts, upright jack support posts. Accelerator, CA, accelerator. Apply the accelerator to the opposite side of the joint to where you apply the CA, if possible. -- Regards, Jon Page
