Free e-book Ultrasound Guidance for Vascular Access and Regional Anesthesia [Download Link]
I have a pdf copy in Pictures Directory, US Guide for Vasc Access etc. and in a folder on my desktop.
In Chapter 3 of the book, pp 19 – 22 there are excellent instructions on how to make an inexpensive model for vascular practice[using tofu] including passing guide wires.
