John, Sounds like I need to go out and buy a few more center punches. I have a couple, but both were too small in diameter to accurately fit into the well of the countersink. Thanks for the simple suggestion.

Use a centre punch. Centre punches come in a range of sizes or diameters. The outer diameter at the pointy end, of the punch, should be the same diameter, or slightly less, as the diameter of the screw hole in the metal hinge. So, the centre punch goes into or through the metal screwhole and is automatically centred. Give the centre punch a few persuasive taps with your hammer to make a dent in the wood. The tapered dent is then used to locate the point of your drill. Voila! Don't try to punch all the holes at once. Make a punch hole somewhere near to the centre of the hinge, drill it, drive in a screw to lock the hinge in place and then move to the others, one by one. Here, I have centre punches that range in diameter from 2mm's through to 10mm's. Sorry, I don't know the vulgar fraction Imperial equivalents. Hope this helps. John M Melbourne Australia.

My Grandson's toy box project continues, and I have a problem. I'm using a piano hinge for the lid and having a heck of a time getting it to remain straight. There are holes every 2 inches along the 48 and they accept countersink wood screws. The problem I'm having is getting the screw started in the exact center of the countersink opening If I'm a little off (and often I am) the final torque of the screw move the hinge away from where I want it, and even a 32nd of an inch makes it a mess along the 48 inches. I'm going to start over by flipping the hinge over to have clean wood to work with. What tool or jig do I need to create a nice clean punch that I can start the wood screw? I've tried using a larger drill bit to put a slight depression in the center but it's not sharp enough to help. What do you seasoned experts do to get those screws started in the exact center? Gratefully awaiting your advice. Dave Carlson Sent from my Dell Latitude E6520 using Windows 7, San Francisco Bay Area
