CA Glue & Cracked Pin Block

[Lance Lafargue]

I suggest you look at the archives since this has been discussed a lot
lately.  I hope Bob and Bill don't mind if I forward these old posts. 
There are many in the archives.....

 1.  Do you putt CA on pin where it enters the bushing and let it run down

 the block?
 2.  How much CA do you actually use?
 3.  Do you put it all the way around the circuference of the pin or just
on
 one or two sides?
 4.  Where do you buy CA in bigger quantities than the itsy bitsy tubes?

Yes put it at the bushing.  Let it soak in until it will take no more.  I
usually come back to the pin(s) several times within a ten or so minute
period.  The block will "tell" you when it wants no more.  Do the
circumference.  You can buy CA at Hobby stores.  They sell it in several
viscosities:suggest you get the very thin, and the medium.  I buy several
at a
time (about $6.00 per bottle) , mark the bottle with magic marker as
follows:
# 1 of 2 ; #2 of 2, etc.  This helps you keep track of your inventory.  I
put
the bottle(s) I'm not currently using in the refrigerator.  This increases
shelf life.

If you're working on a grand piano, I would recommend you cover the action
with foil or some other protection for the action.  Better safe than sorry.

Hope this helps.. It's great stuff!  It will even cure the common cold.

By the way-be sure you are always ventilating the area in which you are
working with this stuff.  It emits Cyanide fumes.  That's how it cures the
common cold.  It kills the victim, but he/she will never have the cold
again.

<<1.  Do you put CA on pin where it enters the bushing and let it run down

Yes, with a capillary tube so as not to drop any on the plate.

<<2.  How much CA do you actually use?>>

Depends. Worst case scenario I had was two to three ounces. I have also
treated well with a half ounce.

<<3.  Do you put it all the way around the circuference of the pin or just

Use thin and it will flow around, you will see a meniscus, that will drain
away. You might go over it again after treating one or all sections, until
the
meniscus stays or drains away very slowly. That would indicate that the pin
area was "full."


4.  Where do you buy CA in bigger quantities than the itsy bitsy tubes?

A really good airplane hobby store. "Jet" and some others come in 1/2,  1,
2,
and even 6 ounce bottles. About $10.00 per ounce.
