" I broke one of the links at the bottom of my Lee Classic press. They appear to be made out of a cast alloy. Yeah, I know, you get what you pay for!"
I wonder; the Lee "Classic" press? That's an all cast steel alloy press body and toggle link system - not cheaper/weaker cast iron - and you broke it? Goodness!
Even the older alluminum alloy Lee Challenger presses are quite strong. But, if the bolt connecting the two-piece toggle link together becomes loose it lets the toggle blocks seperate a bit. That changes the geometry of the whole toggle system, enough to pry the halves apart and then they can break. The press instructions - and common sense - says to keep that bolt tight. So, IF it's allowed to loosen and that breaks the link, is it really Lee's fault? Well ... maybe not?
Some people seem to think comparing Lee's lighter, less costly alum presses to the cast iron of others is honest; I don't. Invalid comparisons, just as equating an RCBS alum alloy press (Partner/RS-5, etc) to a cast steel Lee (Classic series) for total strength, are silly. Compare compariables and they will be equal. In fact the Lee Classic Cast/Classic Turret presses appear to be stronger than the Rock Chucker and some others in their general class.
Note too that some folks can, and do, break any press ever made, no matter the cost. And how costly must a very simple piece of steel gear be before "free" life-time replacement parts really aren't worth the initial price? I understand mechanical things pretty well and I don't bend or break much so free repair parts mean little to me.
I agree with Marlin 45, we get our money's worth from Lee's tools. And, by comparision with others, much more than that from many items such as their dies and presses.
