Beam Engine Column after turning, before plating


I still have not got the hang of this blogging stuff.
I tried to post 3 photos together, but wordpress accepted only the last photo posted.
So here is the first one in the series.
This is the casting of the beam engine column.
As you can see, it is roughly the shape desired. It was quite heavy, and had a very tough external skin which required carbide tooling to break through.


3 photos of the beam engine column
1. The casting, roughly the shape, with a very tough external layer
2 After turning, nicely shaped and shiny, but quickly develops surface rust
3. After nickel plating, not perfect, but not bad for a beginner. The nickel only plated those surfaces which had been machined. A few deep pits on the surface did not accept the nickel plating. I had conflicting advice about the adviseabilty of plating cast iron, but overall, I am quite pleased with end result. I might have overdone the electroplating brightener additive. One colleague called it engine “bling”.
