Βάλτε σωλήνες 1,5 ίντσα μαύρη 1,5 - 2 χιλιοστά, να τις βάψετε με αστάρι και μετά λαδομπογιά, το σύρμα γαλβάνιζε 3 χιλιοστά, και το γάμα που κάνουμε με σίδερο 12 χιλιοστά 18 εκατοστά, το στραβώνουμε στην μέση, σας ευχαριστώ
Using 1.5 inch pipe, with 2mm wall thickness, for the posts and the horizontal bars, and 12mm rebar for the corner connections, you can easily make an arbor for your vines.
Innitially, you'll have to establish the 4 corners where the vertical poles will be standing, marking the area of the whole construction.
Dig about half a meter in the ground and secure the first pole with concrete.
You''ll have to be thorough about this first "collumn" because it will be the base that will define the positions of the other columns. The hight can be as high as 2 meters above ground, it's realy your choice. The same goes for the length of the sides.
The important part is to keep that first column totally vertical. Or at least as vertical as possible.
After it has settled, you can take measurements and position the other 3 posts, measuring both the sides of the square and also the diagonal of the square, if you want the arbor to be totaly square and 90 degrees in the corners.
Ofcourse you can still do it with less accuracy if you don't have any specific needs.
The horisontal pipes will be held in place with 90 degree elbow connectors that can be made out of 12mm rebar, 18 cm long.
Weld the connectors on the posts and then weld the horizontal bars to the connectors, to secure them in place, and the basic frame of your arbor is ready.
Make a network of galvanised wire on top of the arbor, at distances about half a meter to each other, to form the bed where the vines will lay, and you're ready to enjoy your morning coffee in the shade of your beautiful vines.
Remember to grow only organic vines that don't need any spraying or pestisides.
The pipes will need to be painted, in order to withstand the weather conditions, and at the bottom of the vertical posts, about 2 - 3 cm above ground, drill a small 2 mm hole on each post, for water drainage, so that they won't rust from the inside.
Alternatively, you can fill the open top of the posts with PU foam, it will do the same job.
