Maybe it was my Jacobs chuck or the forstner bit but every time I'd try to drill a deep hole with my forstner bit extension, it was like a real chore to turn the tailstock handwheel. Almost as if I needed a cheater bar to tighten the Jacobs chuck enough to stop the extender shaft from spinning in the jaws.

Tried out the Strongbore system from Carter Products today and WOW oh WOW, easy peasy. Almost effortless advance. Sure is nice when performance meets expectations.
