This is one of my new pieces it is made movingui , the metal going through the wood is aluminum and the base is steel. I love the fig. of the movingui and how the metal and the wood change with the light .
The wood top is awesome! I hope you plugged the top of the pipes or they will end up as trash receptacles. I was a welder before I retired and every time I left a pipe uncapped, it was guaranteed to end up with all sorts of trash in them. Maybe you have better trained people around you! Nice job otherwise.
I sanded it to 400 grit and used tung oil about 9 coats with out the oil the wood seemed to oxidize in the air but it really came alive once the oil was applied.
