I bought an ounce of 3M CA40H from Mcmaster-
Carr, to replace the expired Locktite superglue
that we normally use.

I like the 3M much better. No white fur around
the bond, seems to harden in a linear and
predictable way, giving you a little time to
fine-tune the positioning of the parts and an
excellent nozzle on the container.

What is the McMaster item number?

Could be due to the thickness or viscosity. I flew model airplanes for a
while, several years ago, but still find myself buying a lot of glues from
my local hobby shop.

They offer super glue in three viscosities from super thin (much like water)
to medium and thick (like light syrup). The thicker the glue the longer the
set time. They also have debonder and accelerator. You spread glue on one
surface and spray the accelerator on the other surface, and get a full cure
in about two seconds.

They also have 5 and 15 minute epoxies that serve very well.

I should have given an example. I had to tack
down a tiny length of 30ga wire wrap wire on a
prototype. With the Locktite product, regardless
of the viscosity (I have all three), the glue
has zero holding power when first applied. With
the 3M product, it started holding the wire right
away, but still gave me plenty of time to fine-
tune the position.

I've also used the accelerator and I generally don't
like it. Stinky and gives me only one chance to
get it right.

This technique has probably been obsoleted by the Church or Antismokerism,
but someone once taught me that the cure of the syrupy stuff (for gluing
down #30 wires) can be "activated" by holding a burning cigarette under it,
letting the second-hand smoke waft against the glue. (you have to hold
the board upside-down, so the glue is above the red ash part of the cig.)

For what it's worth.

Cheers!

I think they have 60 sec two-part epoxies as well, up to 90 min.
The advantage is these last near-forever when usused, don't even really need
to cap them!

Loctite and someone else, mebbe Devcon, make a super-wide array of two part
stuff.

I suspect the two part stuff is tougher than the one-part stuff, a better
polymerization dynamic.

I read that bearings that would normally be press fit are actually stronger
when epoxied in -- tremendous shear strength, with any kind of area.
1,000's of lbs per sq in, iirc.
Which, if the bearing is doing its job, shouldn't even be necessary.
You need, tho, about .010 to .020 clearance, on the radius.
But proly not heat-resistant, at all.

On Check Sorters years ago, we always loctite the bearings on the outside.
Save the major casting from being trash when a bearing floze. The center
was loctited also, but would normally breal loose. But the center rode on
replaceable studs.
