Regardless of which type of screw you use, you'll need to flip the panel and use a countersink drill to on all of the exit holes. Drilling MDF leaves bumps, the countersink bit will remove them, and will create a little bit of space for material drawn up by the screw from the second sheet of MDF. You want to remove anything that might keep the two panels from mating up flat. I set a block plane to a very shallow bite and ran it over what was left of the bumps and over the edges. The edges of MDF can be bulged by by sawing or just by handling, and you want to knock that down.
“Woodworking in Estonia” by A. Viires (National Technical Information Service). This is our share of the booty from the cultural exchanges of the Cold War years. The Soviets got models of our nuclear subs, and we got one of the best books on folk woodworking ever. Aside from showing how to make everything from wooden wheels to bentwood cheese boxes, this book is also an education in the way Eastern European history gets written. Imagine Eric Sloane dividing early American woodworking into feudal, capitalist and socialist periods!
This book was put together to introduce people to the world of carving, and I think it does a great job. Starting with tool selection, sharpening and other important, but often overlooked aspects of the craft, it moves on to discuss chip, relief and sculptural carving. With a chapter on surface decoration as well as a section of scaled patterns to get you started, this book has a bit of everything. And even if you’re not interested in traditional carving projects, the skills learned in this book will introduce you to techniques that can be used to add texture to your next furniture project.
@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.

Grizzly is a company currently undergoing an upheaval. This brand was once known as a manufacturer of professional grade tools and equipment for woodworking products. Though, in recent years, that reputation has begun to slip a bit since being bought by the Chinese company SIEG. These days, whether the Grizzly product stands up to its previous standards of excellence often has more to do with what you are buying than the company itself.
