Drilling a 60 cm long hole that is 40mm in diameter through the foundation of My PlayHouse.
I have bought this Diamond Core Drill Bit Hole Saw - :http://www.aliexpress.com/item/40mm-45mm-or-50mm-Sinterred-Diamond-Hole-Saw-Drill-Core-drill-Bit-for-glass-ceremic-Marble/32297057397.html
But it was like really short,, so i fund a way to make it longer,,a lot longer...
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
