Hi,
I just saw this and thought i would share!…for those of you who prefer a Benchmate system over a ball vise…(the newer benchmate also stays centered…great for under the microscope…).
This adaptor allows for the use of the Jura workholding fixtures with the newer benchmate ring clamp…
it has a different ring clamp from the older version…the Jura attachment shown in the link fits the newer ring clamp…
(i have the older system and ring clamp…but GRS does sell the parts to convert the older brackets to be centering)
