adobe illustrator - Diagonal lines for brush stroke or dashed stroke

I would like to stroke a path with 45 degree diagonal lines that are set a fixed distance of of 0.125 inches to each other.

I'd also like the diagonals not to distort on curves- in other words, I want the diagonals to remain straight line segments that are parallel to the tangent of a curve at a any point.

I hope this is clear.

Is this possible?

Update:

This is for laser cutting a pattern - Adam's solution works nicely.
