"I'd like to see them make "
Anyone old enough to remember either Popular Mechanics, or PopularScience magazines will remember this collumn as a regular feature.
I would like to have a self-skimming arangement on a new or heavily re-piped boiler.
Surely the oily water could be concentrated in the skimming port (as it splashes around) with a drop down connection to the return. Thus the oily residue would float in this piping, isolated from the main boiler water, and able to be drained away occasionally, without losing large quantities of water.
Anyone else have any desires for some improving change or gadget?--NBC
