these next photos of the build is the start of the planking I have marked out from the right 3.3cm -- then 6.6cm -- then 10cm the reason is to form a patten for the black cord so you start at the above the centre line with length 10cm glue then another 10cm along the line, place the black cord going down then plank 6.6cm then 10cm black cord down fill the end cut out the hole and squares very carefully, third row down is starting 3.3cm then 10cm not forgetting the black cord down in the middle of the joins carefully cut the holes etc after the planks have set, what I have done so far on the main one end has taken me just over 5 hours and you can see the patten the 5 hours has been over three days, so far with the planking I am very pleased with myself alot better than the lower deck I'm just taking my time so many more hours to go .
