Ok, given how nasty this stuff is, is there anything else you
recommend that isn't so nasty?

I have one mosiac I need to glue together; otherwise, they'll be
no way on either to get it to travel (and we have to move soon :(..).

Thanks,

MEK (Methyl Ethyl Ketone) as a "glue"!

I used to use MEK to clean the screens used in silkscreen printing. MEK is
some NASTY stuff! Extremely flammable and you don't want to get any on your
skin. (It won't burn you, but it soaks right into the skin and is very
"cold"...)

Back in my sign industry days, we occasionally used an MEK hybrid to "weld"
plexiglass and acrylic signage together. We didn't have the "guns" that the
Lego Master Builders use, but we did have small squeezable plastic bottles
with a long syringe needle on the tip. It allowed you to dispense either a
tiny amount or up to a big pool of that nasty stuff.

You might want to look in the Yellow Pages for a Sign Supply company in your
area. Ask for Acrylic Cement Applicators. (You might want to confirm that
they are compatible with MEK, as we were using some hybrid chemical in our
applicators...)

Hope that is of some use!

I am tired of my lego sculptures being knocked to the floor by the antics of
my rambuctious sons.  My 1:1 scale Miniland reproduction figure
(http://www.actionbrick.com/Lego/Maxifig.asp) has fallen a number of times,
and it is not easy to rebuild! :)

Instead of placing them in a cabinet, I would like to glue them together
(the sculptures, not the sons!)

Years back, I've used the Oatey PVC & ABS cements on my Lego globe, but I
want something more precise than the
"dip-the-giant-blob-on-a-stick-into-the-goo-in-the-can" applicator.

Has anyone made a system similar to the one I've seen in LLCA model-shop
photos?  It consists of a clear MEK-filled "IV" bag, hoisted into the air,
which gravity feeds a small handheld trigger gun through small diameter tubing.

Does anyone know where I could get/make/construct the handheld gun? Has
anyone attempted construction of such a device?
