I'm havibg trouble with my LEGO sets. I build the Saturn V rocket. Pieces
keep falling off all the time. I'm tired of putting the pieces back again.
Can anyone please recommend a good, strong gle? II've tried Superglue(Locktite)
but it doesn't grip. Maybe new bricks are to smooth because pices stiull
fall off.

Which pieces keep falling off? And why? Are you knocking it a lot?

I would not use glue as you damage the parts forever.

MEK solvent is what Lego uses for their large models.

Starbeanie mentioned about the MEK solvent LEGO has used in the past. I think
LEGO has moved onto another "glue" since MEK produces a very toxic vapor.

I use MEK quite a bit for large corporate models that will be shipped and handled
quite a bit. Make sure you have ventilation, you don't want to breath that
stuff. Also understand that MEK is not a glue, it is a solvent. It melts/welds
the LEGO together. It looks and behaves like water, but it instantly etches
any surface it touches. Don't get it on you models finished surface or your
fingers for that matter, you cannot wipe it off. If you do get a little on the
surface, leave it alone. Let it evaporate and it will leave as little damage
as is possible.

I use a very, very thin tube and hobby glue bottle to apply the MEK. I picked
them up at a hobby store. As a matter of fact I even put a small round piece
of metal inside the tube to slow it down even more. I want to have a little
squeeze to get it to come out, otherwise it may gush out. Don't apply too
much. AND YOU SHOULD DEFINITELY PRACTICE. You will see what I mean when you
try it. Squeeze out is a problem.

Apply it to the top of the stud to help prevent squeeze out, When the LEGO surfaces
mate, it will spread and make good contact.

Anyway, I could go on. It is a good, permanent solution, but don't forget
to practice before using it.

For fragile parts of the models of normal ABS bricks, I use Revell 39604.

Beware that flexible parts such as plants (PE) and transparent parts (acrylic)
are made of different plastics that do not always react the same way. Try first
on spare or broken parts. PE usually does not glue at all but can be attached
by heat.

That is correct. MEK works on ABS. It does not work on baseplates, flexible
plants, and other flexible parts that are not made of ABS.

I often use standard super glue on those parts. There are likely better solutions
for those parts, but I rarely use them in my commercial projects.
