Here is something I came across on Facebook that I felt would be of interest. The scratch construction of a Homemade PVC excavator, meticulous down to the last detail.
Almost dropped my coffee when I saw the workable windshield wiper!!!

I saw this on a video on Facebooks. Gotta give props were props are due. THat build was amazing. The level of detail is amazing.
I’m astounded how precise his work seems to be with those basic tools.
This is the youtube channel of the Vietnamese guy that is working with PVC and doing such great work.
There is the full excavator build plus a truck and some other interesting projects
