How to Find the Perfect Balance Point for a Wall Plaque?
We would like to make personalized signs as handcrafted holiday gifts for the young members of our family. We got a router-based sign making kit. I tried it out on a piece of scrap plywood.
I stupidly put Spouse's name on it, and she turned it into a project instead of a prototype. It happens often in my woodworking. I should have chosen a vulgar word instead. :-o
The final step is to use a keyhole bit to rout a picture hanger. You plunge the bit in to make a round hole, then slide it up to make the slot that wraps around the screw or nail head. Stop the router, slide it back, and remove the bit through the hole you made. Easy peasy. I used a clamped board as a guide, and the slot is perfectly vertical.
I can measure to find the center between two points easily enough, but it isn't always the "balance point". Despite my best efforts at measuring, balancing with pinched fingers, and everything else I could think of, the slot was not quite right. The prototype hangs with a slight tilt. My guess is that the slot is off center (left/right) by 1/16 inch at most.
I could make two slots, but that makes wall hanging difficult to get right. Those wavy nail-on picture hangers are less elegant than the carved slot that I want.
-> I would like to make the signs/plaques with single, perfectly balanced hanging slots.
Once the slot is cut, it is hard to fix balance problems. You have only one chance to get it right the first time. It happens often in my woodworking. :-(
-> How do you find and mark that perfect balance point? Do you have any tricks to share?
