We parametrize the torus knots by s in [0,1]. Let w be the rational number such that the curve winds around the meridian w times when it goes around twice the length of the torus. The speed can be computed as a function of s, t=s*w, and the two radii R>r that define the shape of the torus. The speed assumes its minimum R-r whenever w=0 and sint=1. We transform speed using f(x)=(R-r)/x and produce the models by sweeping a circular cross-section with radius proportional to f of the speed. Growing w increases the speed and produces progressively skinnier tubes that wind more and more around the meridian.
