Regarding your rail bolt covers, hers an idea..:
Our bolt covers are nasty and damaged from being carelessly removed with sharp objects, countless times.
Since these also kind of serve as markings, we’re probably going to
find some stainless steel “carriage bolts” with heads of the appropriate size, chop of the threaded part and some how make em stick in the holes.
We’d probably stick the heads into the buffer to polish em to match the chrome accents. And being that there are carriage bolts showing on the corners… its not something that would look out of place on this table.
Sure its not beautiful inlays…. but its prettier than the rubber thingies, and it ads to and complements the industrial/commercial appearance of these tables.
