The total cutting area is about 12" x 8" x 3" (X by Y by Z).
The rails and bearings required over 100 5/16" nuts.
I estimate that the whole thing cost approximately $650-$700 to build including Ontario taxes.
Note: I built the whole thing with a regular hammer drill (which has a switch to become a normal drill), a hack saw, and a jig saw. I had no drill press or chop saw that made perfect cuts/holes. Of course a drill press and chop saw would make the whole thing go a lot faster than it did for me.
In each step of this instructable, I will show what individual components I used.
If enough people (or any at all) want to build one like this then I will use SketchUp to create some plans. But for now, this is really just to give some ideas on how to build one yourself.
Step 1: Router (Spindle)
The only one available to me at the time came as a set so it came with a fixed base and a plunge base.
