Craftmanship

The variation of strength implements encompasses a large spectrum of shapes, materials, and functions. We’ve seen Indian clubs, circus globes, shot-loaded bells, and of course, plate-loaded bars in recent times. 

Focusing for a moment on iron plates, it’s essential to discuss the basics. 

The process starts with a design, continues with the casting, and culminates with the machining and finishing. 

All vintage weights are cast iron with gray iron as the foundation. 

A plate’s casting quality is significant in assessing and differentiating craftsmanship. The crispness of the lettering, the smoothness of the surface, and the consistency in size and weight are all byproducts of the casting quality. 

Some designs have distinguished themselves, and their creators’ attention to detail has stood the test of time. The proportions of the twenty-five-pound Marcy Los Angeles plates are without equal. Jackson’s cross-hub and lead-pocket feature blend form and function with unrivaled harmony. And, of course, the muscle man that adorns the Zuver Hall of Fame plates is iconic. 

Another aspect that separates the higher quality plates from the rest is the machining involved. Some plates have no machining at all. This is not necessarily a negative; however, the difference is tangible in the overall fit and finish. 

One typical process is to machine the center bore. The fronts, backs, and even sides are machined to varying degrees. Earlier in the 20th century, lathes were used, and later plates were milled. The lathing and milling served dual purposes: to ensure consistent finishes and calibrate the weights to particular accuracy grades. 

Plates with higher degrees of machining (i.e., Bergs, Jacksons, Eleikos) typically exhibit precise fits, finishes, and weights. 

It turns out that weight is not always weight.
