I have a hand-held battery powered foam cutter (these can be found at any hobby/craft shop). I find it quite useful, however I'm quite often frustrated by its inability to do detailed work. This instructable is simply a tabletop flat bed version of this handheld unit.
-Makes detailed work easy.
-Inexpensive (only a few dollars in parts)
-Small (easily storable)
Lets get started;
Step 1: Parts & Tools
Here is a list of the parts I used. Many of these can be replaced by easier to obtain equivalents, or cheaper options.
(also the metric components can be replaced with their nearest imperial counterpart if you are in Canada or America (M5 = 5mm ~= 1/4")
Parts: (Approximate cost $15)
-Bolt (M5 x 30mm) x 2
-Nut (M5) x 2
-Washer (M5) x 3
-Bolt (M3 x 15mm) x 2
-Nut (M3) x 2
-Washer (M3) x 3
-Nut (M20) x 4 (these are used as legs to lift the board off the table so 4 chunks of anything about 15mm tall will work)
-Nichrome Wire (can usually be found at hobby shops beside their foam cutters as a replacment part)
-Battery holder (2 x AA)
-Small Cutting board (mine was 16cm x 26cm)
-Wire (about 40 cm)
-~40cm of 4mm diameter metal rod
-Hot Glue Gun
-Soldering iron (I used a soldering iron to melt the holes into the cutting board this is because I did not have access to a drill)
