Why why PE metal parts

[Calico Jack]

I have used this CA pretty exclusively for photo etch with great results. It's a bit pricey, but offers some flexibility when used with PE that it can take light abuse without parts flying.

They also have it in a thicker viscosity and also black.

Oh and just a little tip when dealing with photo etch. If you have to make bends or rounding, it's best to anneal the PE beforehand. This will soften the rigidness to allow better bends and retaining them over wanting to spring back to it's original shape and allows easier gluing. HTH

Some even use white glue (PVA), and I have seen some modelers use Future to attach some PE parts.

What those of you who have trouble applying CA to tiny parts need, is to make some of these: They are cut off sewing needles of several sizes, from small to microscopic, mounted in dowels and color coded for size.
