Or sandwich it between two pieces of say 60 grit sand paper and hammer.

I realise from the first post that the asked for dimensions were between 3 -6", but a neat way of utilising the brass drain bend would be to use the union nut screwing down a glass lense and behind that, a small gauge to fit in the union (in the pipe). That would look very steampunk-ish I reckon.

The mates gauge turned out to be an absolutely beautiful 5" brass 800 psi that is still in original wrapping and operating perfectly - I just couldn't bring myself to abandon it tacked onto a pizza oven.
Looked around some antique shops and eventually found the attached 6" for $50.

Some good contacts today convinced me that heating swarf in an open topped mould with a torch is a recipe for disaster.
Plan B is to cut the lever shape out of barstock and then to apply the techniques described above.
I wonder if the old tradesman tool markings were really letters shaped out of brass wire laid into grooves, then melted with a torch.
