More complicated models use a Gaussian potential constrained to a finite radius or a mixture of polynomials to achieve smoothness.
Some reposados can also be aged in new wood barrels to achieve the same woody flavor and smoothness, but in less time.
Their second-order balance, owing to the 90 bank angle and 90 throws, means no additional balance shaft is necessary to achieve greater smoothness.
See just how easy it is to achieve long-lasting smoothness with Philips Lumea.
However it is understood that these methods can never achieve the clarity or smoothness of its overcranking counterpart.
Definition: Scraping/sanding a surface to achieve smoothness.
Organ voicers strove for an articulate speech characterized by chiff and avoided nicking, beards and other means of achieving 'smoothness'.
