I bought a Lyman 4500 with a electrode heater when they first came out !
That was back about 2002 I think . Used it with no problems until the spring of 2008 ! Then the little screw cap that goes over the sizing die and holds them in kinda stripped the threads .
Called Lyman and they tell me it happens and they can sell me a new casting for $50 !
So instead of that I ordered ANOTHER 4500 with a heater . Whole thing was about $130 . Later I had a guy where I was working at the time rethread it and make me a new cap to hold the dies in ! Still works alright but it ain't the way it came from the factory !
Then yesterday I was using my newer second 4500 and the rod that goes down thru the lube came up thru the bottm of the casting !
I haven't called Lyman yet to complain but I will ! And even though I've not had this one a year yet I bet they don't replace the cheap casting again !
Now I know anyhting is possible and maybe I got one that had a void or whatever in the cast iron . But I am wondering if this is something that has happened to many others ?
