When trying to apply a small drop of CA glue to a part, sometimes a pin head does not pick up enough glue, especially if it is thin CA. If you cut the top off a needle's eye as shown below, and dip it into the glue, surface tension holds the glue in the gap and it can be applied to the part. You can use different size needles (eyes) depending on how much glue you want to apply. A handy container for the glue is the protective plastic cap that covers the nozzle of a new spray can.  |

Hello.
Without wishing to sound stupid, what, exactly, is CA glue, and where can I get it?

CA glue is cyanoacrylate - also called superglue - and the normal version is the thin one.
Use only one drop per square inch, therefore Mike's suggestion of using a needle to supply mini droplets. Bed careful though, 'cause it bonds skin very well.
You can get it from all hobby shops, building supplies, and most office supplies.
The only glue really to use on metal parts.

For bonding the very small fiddly parts, DEFINATELY!
Epoxy would be an unmitigated disaster on a porthole cover 2mm diameter........

Here is an example of the pin gluing process used to glue railings.  The railings were fitted dry and then the stanchions were individually glued in place. |
