I've been reading these posts and on occasion I'll see Super Glue or CA mentioned and I would like to ask, what is it being used for? Are you mixing it with wood dust and filling cracks or to keep a crack from letting go?
From my past experiences with CA in a tube is that I bought it for $3.98 or what ever, used it once, put the cap back on and the next time I went to use it the whole tube would be hard..
I've also scraped it off of glass and couldn't figure out what I had in between my fingers that felt like a piece of steel imbedded in the skin but there was nothing to be seen until I looked with a magnifying glass and saw the tiny little almost invisible slivers..Only way I could get them out was to scrape against the grain with an Exacto blade.. Don't look forward to doing that anymore!!
