I have been scouring the internet for some ideas on how to convert a broken piston style foot pump to something I can use to power an air brush, at least until the hobby shop gets stock of compressors - about a months time they believe.
I was thinking of something that was hand operated.
Has anyone got any ideas, or for that matter a link to something that could give me the ground work?
What I have come up with, is a wheel with 2 shafts connected on opposite sides connected to the pistons with a hinge, but on paper it works, but when I think about it, I cannot see it working.
