Afternoon all,
Now you are going to love this one!!!
Tried Aladdins cave this morning, as suggested by your good selves, but to be honest they did not seem too keen to help, very busy with people buying miles of pipework, no worries, appreciate the recommend and have learnt a little more.

So went on my merry way, different things to do, then , later in the day on the way back the missus said "lets go in the first shop we tried two days ago", ( the shop up soi 88 a little from the market turning opposite 1 sport entertainment, has the Berger paint sign outside) so we just walk around to look for a nut, this we did for about two minutes....

then the checkout guy ( a different one from the other day I might add) asked if he could help, she showed him the offending machine, and guess what........he pulled a box from under the counter full of nuts and backing plates wrapped in plastic.....oh yes, we have s%£tloads of them!!!! ( my translation!!) he said, 120 Baht each.

So after driving all round HH they were in the first place we looked all along!!!
Can only happen in Thailand!! but a happy ending, and another funny anecdote to add to the repertoire.
Going to have a beer to celebrate, and start the wall again in the morning....it is Sunday after all..

.but seriously... thanks to all the posters in the community who always seem to pull together no matter how trivial the problem...

A game of bridge is like sex, if you don't have a good partner you'd better have a good hand.
