I understand your concern. But personally, I do not have that problem AT ALL. I use Buck chucks daily and have been for many decades. They are just as good as the first day I bought them new. I take them apart clean and grease about every 6 months. I NEVER wrench down on stubby parts barely in the end of jaws, that will spring your jaws. I always clean the material before I chuck it. I can go on, but I think you get the idea. I try and take care of my chucks and that goes for everything in my toy house. I firmly believe the chucks I own will outlive me. Giving outstanding accuracy all along. I do own full sets of Hardinge 5C collets and lathe chucks to hold them. But because my Buck set-tru chucks are so nice and accurate the collects collect dust (very thick dust!). And I’m not affiliated with Buck & Company in any way…Dave...Happy Father's Day
