If only I had headed those words and not gone to B&Q without my backofanenvelope calculations which left me with ply cut short. However after a bit of head scratching and ponder and some tea drinking I realise that I could add on a section at the end. Due to the lightweightedness of the baseboard it shouldn’t be too much of a problem and with extra bracing for attaching to the main board everything should be rock solid!
However in the measuring fiasco it means that I will need to get some more ply for the top and so a trip out to the timber merchants on Monday for another sheet of 8×4 6mm ply. This does mean I have quite a lot left over! Do not be distracted, do not be distracted… repeat.
