I am nearing the end of a grandfather clock project, all QSWO (I will do a big thread on the whole process from lumber to final product), and I have an issue to overcome. The door is separated into two glass panels, with a 3/8-in x 3/8-in rabbet to hold the two panels. One goes over the clock face, and one goes over the pendulum and weight compartment. I will use double strength glass, 1/8-in thick. That leaves 1/4-in for the glass retainer. I'd like to make these from 1/4-in square QSWO scraps such that the retainers are not noticeable and blend in with the finished door, and sit flush with the inside surface. Can I carefully drill these for a tiny brass screw to go into the door? It seems awful small, and I'm sure I can get a drill bit small enough and safely drill everything, but is this enough? I'd very much rather use oak instead of the cheesy plastic retainers I've seen in store. I solicit advice - go with the oak? What size screw is appropriate?
