I tried making a similar cable a few years ago. It worked ok for a while, but then the tiny wires soldered to the DA-15 (note: not DB-15) connector snapped. I think the small conductors in a VGA cable are just too hard to work with reliably.
To replace my continually-failing cable, I made a small PCB board. This works much better, and is still very cheap. I have a few spare PCB's that I can provide for the cost of postage (about $3 internationally).
