Swarf Puffer

[olderdan]

I have a compressor but do not use compressed air on my machines, however there are times when a bit of air to clear swarf from blind tapped holes etc would be useful. I have tried cheap plastic ones which dont last long so decided to make one. I had a gas ram from an office chair which had failed which seemed a good place to start. Made a new O Ring piston and a nozzle from bits from the scrap box, turned out really good and heavier than the plastic ones so more stable to use. I can see me using it for clearing dust from drilled masonry holes also.
