Yes, a picture or two would be great. May be one showing it in
relation to the carriage & cross-slide, i.e. perhaps a bit further
away so I can see the "bigger picture". A closeup of the assembly
would also be nice as well, however.

How much force is the spring applying to the cross-slide, do you have
a guess? I assume it must be greater than what the cross-slide
experiences during cutting. I wonder how much that would be? Perhaps
a better question is how did you pick your spring?

Thanks.
