How'd you drill a ST when adding bottle mounts? I've read that it's hard to do without a proper jig and drill as stress fractures might occur around the edges. True or false?
I've just marked the places the holes should go and used a hand drill. A jig might be handy (if unnecessary) for getting the holes in the right places, but I can't see how a jig would prevent stress fractures. Or why drilling a hole would produce stress fractures, to be honest, provided its deburred after drilling.

Also, what tubing or rods do you use for racks? Anything you can buy from Ceeway?
