I think the problem here lies in the assumption the use of 0.1, 3.5 and 3.6 as
the basis for triangle with the center of the torus, the bend in the rail.

Keeping the radius and 0.1, your delta X is more like 3.5986.  I think you will
be fine if you follow clipka's suggestion but the change you are calculating
should be subtracted from 4.9.  Also, I tend to have better success with these
things when I declare local points or values and share that between the objects
like:

#local bendX = 8.5 - sqrt(pow(3.6, 2)-pow(0.1, 2));
or
#local pBend = <8.5 - sqrt(pow(3.6, 2)-pow(0.1, 2)), sh+2*rfh/(mr+1), 4.1>;

Cheers,
Mike
