Ah, OK, I saw this post after your other one.
Photo etch can be a blessing and a curse. Gold Medal Models is one of the originators of the industry and makes good stuff. That said, if you've never used it before there are a couple of things to know.
- It won't attached with regular model glue
- It sometimes has to be bent or folded, and this is one area that can make it look great, or terrible.
I have a small glass cutting board I bought for cutting PE. It works better than other surfaces because it's hard - cutting mats or other softer surfaces will flex under the pressure of cutting, allowing the edges to bend. I generally prefer the curved #10 style blade in XActo's line and their conventional #11 for really small spaces (when there's not enough room for a #10. I find that I can "roll" the curved blade over the attachment point more accurately and with less chance of a sudden "zing" of the part departing to points unknown.
The most common glue recommended is cynoacrylate, aka "Super Glue." I have a few issues with it though; it's brittle and gets even more so over time, so that if you have any pieces that have tension on the joint, they could spring free a couple of years down the road. Brass expands and contracts more than plastic with temperature changes, so you can get this tension just in the natural course of changing temperatures. What I like to use is Gator Grip Glue (not to be confused with Gorilla glue).
Some people like to prime the PE before cutting, others wait until it's on the model and prime everything then (the theory being that the joint will be stronger if you don't have paint in between). I like a little of both. Some pieces like doors or vents I'll glue on unpainted or primed, but generally I'll bend the rails, then paint, and then attach and touch up. This is mainly because I mask off the decks and bulkheads for painting, and don't want to destroy the photo-etch in the process.
Bending is the last point I'll touch on. There are lots of tools you can buy, some more expensive than others, but I find that with practice, you can use inexpensive tools to great effect, such as a straight razor blade and a metal ruler, or some smooth grip pliers (smooth on the inside, so they don't "tooth" the brass and leave an imprint. If you do go the razor and metal ruler method, the glass cutting board is a great surface for this as well. Simply put the brass down and lay the ruler on top of it, with the edge serving as the bending point. Then slide the razor underneath the brass up to that edge, and lift it up so that it bends the brass.
