I have machined a wooden base and I will fasten the central column of the cannon chassis to the base. The reason is that people cannot resist swivelling the cannon around on its column and the the wheels tend to mark/scratch polished surfaces. Better to mark a wooden base than a polished mantelpiece. But how to finish the surface of the base? Any polish/paint will quickly develop marks from the wheels. I have decided against making steel railway lines for this model.
I have used an Australian hardwood (mountain ash, a very hard dense wood, reclaimed from a demolished building). I am thinking that I will just oil it. The colour of the wood will darken with age, but will never be as dark as the table, which I made decades ago from Australian Iron Wood. (note, not iron bark. Iron wood. The hardest, densest wood I have ever used. And yes, I have worked with lignum vitae, and Australian red gum. The marks in the surface of the table are only in the polish. The wood is almost impossible to scratch. My kids used to dance on this table 30 years ago.)
The burn mark on the end of the base is from the belt sander. I will remove it with hand sanding before oiling.
The machined finger grips on the ends were made on my vertical mill with a steel moulding cutter intended for metal machining. It worked well.
I discussed the finish which I wanted to achieve with my resident finishes expert. SWMBO. I wanted a slightly darker, low sheen finish, which would not get scraped off with the cannon wheels.
She recommended this stuff. It is a stained, penetrating oil. Smells very chemically.
It is actually a surface repairer, rather than an overall finish but I did what I was told.
OK. That looks good. The surface will be easy to touch up if required.
Then I read the rest of the label….
