Can someone help (Plastics problem)

[PSRusty]

Guys need a few pointers as the people in my club have never used any plastics and do not know how to work it :rant
to see the boat in question goto constructions PS Pilat
My main problem is a set of stairs I am constructing at the rear of the wheel house it is 130 mm wide (5 inches) and 100 mm wide (4 inches), and 115 mm long. i was thinking of using 7mm by 5mm perspex or something similar or similar wood as i do wish to have a wood grain finish to the stairs.

any help would be appreciated.!

I'd probably use styrene in preference to perspex, then stick strips of thin ply onto it for an unpainted look - however!.....
I saw this on a model rail forum (though haven't tried it myself yet) about how to make styrene look like wood... http://www.pacificcoastairlinerr.com/aging_wood/ - if it is painted on the full size boat, you'd only have to do the surface texture without all the messing around with ink and stains  :?

Thanks fer the tip mate thesite had a great idea on how to simulate wood but I try my darndest to use real wood on my ships as I am in the belief that there is no replacement for a genuine reel wood (or Veneer)decking, but i was really in need of info on how to cut it as the scroll saw I use tends to take fairly large chips out of the plastic I'm using I may have selected the wrong type of plastic or need a finer set of blades on my saw but I could not find any styrene in the dimensions I need (around 7mm*4mm)or close to those dimensions.

I also was wondering if anyone knows of a site or info on how to make a stairway as this is my Fifth attempt and Im starting to wonder if a ladder will suffice LOL, But I'd much prefer the large stairs.
