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.
What metal are the rivets on the base ring made of.?
Martin they are dome head stainless steel screws. When painted they will resemble rivets.
