I'm working on my first photoetch set that includes louvers for the engine compartment. The Aber instructions have the "PRS" next to the louver part, so I'm assuming this is the technique of using a ballpoint pen against the backside to make the louvers "pop out".

I've tried it and it seems to work OK, but they aren't popping out as much as I'd have expected. Is there a finer tool to use or a certain surface to be pressing against, to allow this 3D effect to be more pronounced?

Thanks!

I have used a needle to gently pry the louvers. I have also used the tip of a no.11 blade.

So I gave this a go, and tried the ballpoint pen method. I'm really, really not happy with it. Any other suggestions?

If they aren't turning out, to your expectations, save them for later. Get some more practice in and see if you can come up with a new technique. I just found a way to apply a white wash. I have not been able to master any of the mainstream techniques. I just happened upon it.

You need to use a softer surface like most of the standard hobby mats available.

Hi Jake,
I have used corrugated cardboard and have been happy with the results. BTW, nice work on the Steyr 1500. Glad it found a good home.

Here's a link to an aircraft build, he used a chisel to form the louvers http://www.network54.com/Forum/47751/message/1365721986/Cowling+louvers+on+Ford+Trimotor I imagine a toothpick shaped to a chisel point might work too.

A lot depends on the surface you're working on. You don't want it hard, like a desktop. At the same time, it can't be too soft, either. That could lead to warpage of the panel you're working on. I normally use a notepad.

As for a tool, the ballpoint has served me well. It you go with something sharper, you'll really need to watch your pressure. You don't want to accidentally cut through the panel.

I use the tip of a round metal file on a normal hobby mat. It has a finer poin then a ballpoint pen, and is stronger. careful pressure, go slow, and take your time. I do multiple passes to get the desired depth.

@retiredyank -

Well, I didn't really put it aside, I just keep practicing and searching for better methods, and I think I may have found just that... a year later!

Here's my post on how I made this work:

The trick is using an ultra fine tip Sharpie!

Heh, i use a nail.
The magic is that when you press too hard with your fingers the nail hurts like hell
