These were taken a few days ago, and weren't finished at that time. The blocks are sitting on a bed of concrete, the gaps are 610mm. The bearers that the frame will sit on will have damp proof on them. The floor will be 18mm ply, but will be looking at possibly cutting a section out where the machine will be sitting, and pouring a concrete bed, so that its solid. The photos are just to show a start has been made, but thank you for your comments, I'm always willing to listen and learn.
