You don't need special tools,that's the good part. You need some form of cutting mat;a steel rule;a set of pointed tweezers;liquid poly adhesive(Mek Pak for instance,not a tube type cement); various thickness's of plasticard:- 10 thou;15thou;20 thou ;30 thou and either 40 or 60 thou,plus some plastic rod,which for some strange reason usually comes in metric sizes. 6.4mm; 3.2mm;2mm;1mm and 0.5 or smaller if you can find it. The most important piece of kit that you'll need though,is a surgical scalpel with some No.10 and No.11 blades. The reason that I say a scalpel rather than a craft knife is that a scalpel blade is much thinner than any craft blade out there,as well as being far sharper too. You will also require some needle files and at least one engineering file,I usually use an 8" double cut flat file for the heavier filing jobs,and finish off with needle files. For applying the liquid cement,I usually use an old 00 brush. I hope this gives you some idea as to what you'll need.
Good luck with your modelmaking,and don't be put off by your first few being not very good. Never throw them out,if you're not happy with them, as they're a good reminder of where you could have done better. If you're going to build some Federation style ships,I would recommend that you also invest in a compass cutter too.

If you look back through my earlier posts,you'll find two very early models of a Fed DD and CA,which date back to 1991,which whilst not looking very good compared to later models still hold a place of pride in my heart as being my first attempts at that type of ship.
