Got the first three nine foot bits of timber down,,bit of a faff as the wood 4 x 4 has warped a bit.But on the plus side i have bought more than enough sand,and they have bedded down well.Mind you nobody is going to walk over them.Might do some tomorrow,but a walk to Wickes as i have found some great 150 mm wood screws of theirs it comes with a special bit,so i will drill a 2" pilot hole then use the drill to put them in,they will look much better on the surface,plus for added stability i might use Wickes own brand no more nails.Nearly fell out with Mrs P as she once again said they were laid in the wrong place.She wanted them on soil,i wanted them halfway on soil halfway on block pavers edging,to give a more stable setting,guess who won out,it was not me.It's going to look ok.
