Nj N1067 7.1mm Finescale testbed - there may be shorties

[UnfinishedKit]

Terrible photo but I’m getting closer to working point blades after a few wrong turns. 
 

what I’ve learnt is that there’s no way to get 3D printed stainless steel clean enough to silver braze to or at least no way I was going to. Much more sensible to drill through and braze the rail to a brass rod. Lots more fettling to do. 
 

I do think I’m onto something with this high silver content jewelers brazing paste. Perhaps unsurprisingly it makes a much stronger  joint than lead free electronic solder if you do it right. Right is very clean and 715C.

this photo is a little better. The major learning from this run out is that AIA should have printed the railhead a little high so I could grind it back and get a decent surface. 1.2mm instead of 1mm should do the trick
