Here are some photos of a finished table built from a 2440×1240 kit. The gantry is sitting on 3 meter long rails which are mounted to a table made from 65mm SHS steel tube. The long rails allow the spindle to reach approx 200mm past the table rear edge. This is especially useful as it allows machining on tall objects or machining on timber edge or end grain like when doing dovetails. It also allows you to mount a rotary axis behind the table and still have full 2450 long machine travel. There is a 25mm thick MDF base installed with an 18mm MDF spoilboard glued on top. A grid of holes has been drilled and M8 T-nuts installed underneath to allow easy clamping of the material being machined. This is a versatile setup and it can easily be converted to use as a vacuum table as well.
This build can be done in about 2 weeks, with the majority of the time put into welding and painting the steel table.
