Hi John , the box ways on the 10" I would imagine are a little thicker so a simple shim will fix that . Same for the stack height on the cross slide .
I'm aware of the 760 taper attachment and I have been looking , they seem to be scarce to some degree and yes I'm aware of Joel's offering .
While looking for a 760 to fit my machine , I noticed the 700 . Now that is an attachment that really gets my Atlas attention , I don't need one I want one . And I'm only interested in factory . I have asked sellers the over all length for the 700 , seems 15" is it . That seems short .
I just purchased a pair of factory stand legs (been looking for about 5 years) so I'm a little tapped out right now , next month I think I will take a chance on the 700 taper attachment .
Thanks for your post , Mark .
