I suggest buying the pump and valve and tubing first. They are all purchased at the same place usually, any home care or surgical supply store. They usually have some canula there too. If they don't then you can by copper pipe or something similar at the hardware store to fit tightly into the tubing. I can't suggest a size as the equipment may change from country to country and some people like a larger pipe and others a smaller one.
I prefer a 0.5cm tubing for most of my work.
Sorry about the slow tutorial posts, I got really busy at the Club, and the Business, and I only have 6 weeks to finish the book before it has to be done AND printed.
I'm doing them as I do them in the book
