I made this very sturdy frame from Kertopuu (tm) to keep the separate pieces straight and aligned. It also gives such a large piece some nice depth.

Middle piece has a failed attempt on the backside.

I have added MDF spoilboard and surfaced it with the router itself. Now I have a flat and perfectly aligned surface to clamp the workpieces onto. The spoilboard also clearly shows the maximum cutting area of the machine.

Picture was taken before surfacing, I took about 1.5mm off with a 20mm diameter cutter. The surfacing only took exactly 12 minutes with 5000mm/min feedrate.
