No real issues but the wood on mine the wood is really soft right where you drill so be carefull. If I had to do it again I would think about gluing the one side and maybe install that side then after some measuring I would put a small flat on the carbon rod so the drill bit didn't slip on the tube.
Or drill just enough to mark the rod, remove the stab then finish the drilling.
If your not careful you will elongate the wood on the stab.
