CA glue

[Alan Barnard]

There's no secret to it, you just want CA that is water-thin. Hobby stores
may have it or look on the web and find "super thin" or some such. Some use
hypos to put it in but I like a closed system with less chance for leaking
or squirtage (fun new word, I made it up). Schaff's hypo oiler, No. 189,
page 45, works well. The larger one, No. 184, works too but is a little
harder to control the flow.

Safety hints from bad experience:

Where safety goggles. A tiny drop in the eye is a trip to the emergency
room and bad news.

Have acetone or acetone-based nail polish and a rag within easy reach of
your work.

Use a small desk-type electric fan to blow the fumes anywhere except in
your face. Open windows. Do this work when the customer is not home, if
possible, or explain that the fumes are nasty but they are only in the
liquid carrier of the CA and it will have no odor at all when it is cured.

If titlting an upright, spread a dropcloth under and beyond the area in
which you are working, then spread newspapers on the drop cloth. This stuff
can drip and it can run along surfaces and fall off some distance from the
pin you are applying it to. Ruining someone's carpet or floor will ruin
your day! If not tilting, just spot treating a few pins, be patient: Let
each drop wick in before applying more and have a rag right at the spot to
catch runoff.

Certain types of cloth I've used--especially a red shop towel I bought at
Walmart--start smoking when you get CA on it. I've never had one burst into
flames, but there was a definite exothermic chemical reaction going on
there.

If doing a grand, the stuff WILL drip onto the action. You must cover it
or, more safe, remove it. If you remove it, put some newspaper on the key
bed, anyway.
