One of the problems I face is a good source of cheap pressure gauges for various Steampunk applications. Today I think I came up with a reasonable solution. I took an insert for a closet door like this one.
Cut out a bezel, a ring for the outer edge and a back and simply printed a face for it. A bit of spray paint and ultimately it came out like this. The accuracy of the cuts is what makes this work.
At this point the face is not my art so it is just an early piece for testing and It needs a stem for mounting but that’s all. I am quite happy with how this came out.
