I finally made a boo boo... after measuring a dozen or so times I cut a piece of off cut to fit the new 300mm cupboard... after cutting and bringing inside for a fitting check...all was good... till we both noticed....I had the grain of the wood the wrong way round
Guess I'm not as perfect as I thought
All is ok I still have off cut to do it right...I hope..
Today I will be finally sanding... famous last words
Bernie. The offending piece of timber
