RE: Turnbuckle Hatch Latch
I think the interest in the DIY approach came when the price for the
commercial version went from around $15 to $30 with one online vendor.
Plus, it's 'cool' to come up with an elegant solution.  BTW, the turnbuckle
wasn't my idea, I just posted some pictures.  I don't recall who posted the
idea first, it was at least four years ago, maybe longer.
