Hi Mike & welcome,
I can't believe it is over 5 months since I first met you & Gary and set off on the Sammio building road.
Like
Mister Towed lots of this is very new to me too.
But if I had one initial question for you it would be what sort of filler do you use?
Plus do you have any tips for getting such nice "gaps"?
Some examples below (including your own build).
Cheers, Paul.
