Circular needles are measured from needle tip to tip. To make this pattern with your Needlemaster, you can do the 2-circular method for small diameters. Amy has a video on this page: Advanced Techniques
Take 2 cords of any length and put a size 5 needle tip on one end, and put a size 4 tip on the other end. When knitting, always keep the size 5 as the working needle (usually held in the right hand). The working needle determines your gauge, so it's OK for the non-working needle to be slightly smaller.
