Several of the holes were much larger than the shanks so the tacky glue helped to fill the gap nicely. The gaps in over half were too large for CA, even the thick CA to have filled, I fear.  </DIV> <DIV><FONT face="Comic Sans MS" color=#0000ff size=2></FONT> </DIV> <DIV>I have talked with others who seem shocked that I don't use it(CA) more but it isn't reversible and it sets too fast in many cases, no working time. I don't get things in perfect alignment everytime, first time! Apparantly there are those who are perfect out there or they are willing to settle for good enough in the interest of saving a few minutes, I know not which. I just know when I reach for my glue bottle it's the one that says Titebond 90% of the time. <SPAN></SPAN></DIV> <DIV><FONT face="Comic Sans MS" color=#0000ff size=2></FONT> </DIV></DIV></DIV></TD></TR></TBODY></TABLE></DIV></DIV></DIV></DIV><BR><BR></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
