Everything that I've read in my research says not to drill bamboo - something required by all commercially available parts that I've found. So I've been trying somewhat unsuccessfully to fabricate surface mounted ones out of hardwood. Any advice/suppliers would be much appreciated.

I use commercially available aluminium cable stops like these from Nova:
NOVA CABLE STOP SINGLE - RIVET ON BLACK :: CABLE STOPS :: ALUMINUM SMALL PARTS :: BRAZON/SMALL PARTS :: Nova Cycles Supply Inc.

They are designed to be riveted, but I just screw them in.

I pre-drill the holes, then fit them with some epoxy (partly to go in the hole and partly to provide a 'bed'.

On an earlier frame I did drill on the bamboo:


But on the most recent ones I've drilled through the lug material:



Getting the front derailleur location correct is not easy, so the 1x9 drivetrain is a good idea. I'd seriously consider one of the new SRAM 1x11 drivetrains on a future build, but I had a cheap deal on a secondhand 2x10 Ultegra group for this one.

Drink bottles bosses use the standard cycling rivet in bosses inserted in disks of carbon fibre (cut from the shaft of a broken crew rowing oar - sculling, not sweep) and then bonded on. I went to my local bike shop and did this at the counter using their tool.
