Almost ready for the boiler inspector.
Almost ready for the boiler inspector!
It feels like the countdown to the finals medical exams!
So today, I drilled the gas jet from 0.22mm to 0.3mm. A drill bit to drill 0.3mm, is, at least to my eyes, barely visible. It is finer than the finest sewing needle. If I pick up a 0.3mm drill bit I can not feel it. It has no discernable weight.
So this is how I increased the jet size from 0.22 to 0.3mm.
Oops! I forgot to take a photo. I bought a set of micro drills from Jaycar, and the smallest bit was 0.3mm. So I mounted it in the Dremel, and ran it at 10,000 rpm. for a vise I used my fingers. The drill went straight through the millimeter or so of brass with no detectable resistance. Managed to miss my fingers.
0.22mm to 0.3mm diameter is almost a doubling in area of the jet orifice, so I tested the flame. It was (not surprisingly) much bigger! And still a good blue colour, with minimal yellow. So I stopped there. I also installed an adjustable propane regulator Huib.
Then I made an angle piece to secure the boiler to its baseplate.
