The Bris sextant shouldn't need use of welding glass. The images used are dimmed by several reflections. I use the 5,6,7, and 8th reflected Sun image on my home made microscope slide Bris. The base glass is a 52 mm camera filter (pick desired neutral density). A regular glass cutter and small diamond file should be all the tools needed.
