George @gblair thank you. I'm fairly new to a cutting machine, so I'm still exploring the options. After vinyl masks, cutting sheet styrene has been one of the options that I've been experimenting with. Thin styrene sheet is actually easier to cut through than card stock, so no problem with the machine coping. The reasoning is that you can make your own "photoetch", albeit in plastic which is a plus.

I have so far tried to cut out instrument panels, cockpit sidewall detail, undercarriage covers. In reality, there's a clear limitation to how fine detail you can get, especially when cutting circular shapes. Trying a 1/48 instrument panel, my Portrait (which is a low-end model in the Silhouette range) had a hard time keeping the instrument openings circular, but the end product would still be usable after some adjustment. In 1/32 or 1/24 scales, the same instrument panel comes out fine. In 1/72, it's beyond limits of the machine.

Straight lines, as in the wing spar example above, do not present a problem. In fact, just to test it out I have downsized the said piece to 1/72 and it was still a clearly usable part.

There's a company, Hawaiian Air Depot, who is trying to offer "Styrene Sheet Metal" detailing sets for download & cutting at home. I think it is an interesting concept.

The stuff that you are able to print is still pretty amazing, Martin (@editor). I can't imagine doing anything in 1/72 scale. My daughter has a really nice laser cutter and we are just starting to experiment with cutting some things for models. I have "borrowed" my wife's Brother Scan and Cut to make the masks for the 1/28 Dr.1 I am currently building. The cool thing about this machine is that I can scan what I need into the machine, resize it, and then cut it. I have been doing some limited design and printing of parts on my 3D printer, which is also fun. If you have some photos of your instrument panels, could you post them?

Yet another great use for Vinyl cutters in this wheel well truss Martin (@editor). I think back to my Hudson build from earlier this year and I did all that kind of work by hand when I could have done it using the cutter!

Very nice short-cut to add details! The brassin wheels look great!

@clipper I definitely encourage you to give it a go on the next occasion! It is as simple as cutting vinyl, you only need to work out the blade settings. I use blade depth 6, force 33, 2 passes for the 0,2mm styrene.

That 1/48 panel looks excellent, my friend @editor. Very nice technique!
