It seems most of the larger bore flutes have a filler used to create an ikigaeshi (breath return).  What materials work best to fill in the node?  Thanks.

Thanks, Ed.  I thought CA glue and superglue were the same.  Is there a difference?

CA and 'Superglue' are the same, the latter being a generic sort of brand name for CyanoAcrylate. If you do use it (I actually prefer using
a crescent of bamboo cut from scrap), make sure you get the THIN, runny stuff. The good CA, which is available in hobby shops, comes in
several different viscosities in different sized bottles with long-neck applicators. Get the smallest vial and keep it in a ziplock bag in the freezer,
where you'll get a very long shelf life. Left out, it tends to absorb moisture, thicken up, and become useless. You can also buy an accelerator, which comes in a fine mist spray bottle, to speed up the process if necessary.

CA cures fastest in the absence of oxygen (anaerobic reaction), although it will eventually cure even in open air, so if you introduce some into
a crack, capillary action will draw it into the depths of the crack, where it'll run out of O2, and cure very quickly. Mixed with fine granules of
any sort, it will cure more slowly, BUT, will cure very quickly in a basic (as opposed to acidic) environment; baking soda, for example. The
accelerator is just such a medium.

Kind of like an enlightening sort of gibberish, then?
