@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.
Before you start cutting or drilling the pieces that will make up the top, determine the layout of the top. This should include the dimensions of the MDF, the dimensions of the edging, the locations of the vises, and of the screws or bolts that will support the vises, and of all of the benchdog holes and of all of the drywall screws you will use to laminate the panels,
Quality is what we do, YOU will do it too, from day one. We will teach you all stages from choosing hand tools, to picking out wood, to developing your drawings, and building a portfolio of work. There are lots of workshop schools, courses, and magazines that are great for showing you an amateur way of getting a good result. An amateur has no excuse for poor work other than lack of understanding, the amateur has all day to get it right, the professional has not. They must do it right, first time, every day.
Place sounds amazing. Receptionist was rude. Sarcastic remarks were not necessary. I called regarding the private lessons. And was told that they "can't hold my hand to do the work". The person made the statement not allowing me to finish saying that I have experience with wood work. I was really upset by the statement. He did not seem interested in having me as a client/student.
You may even want to put yourself in the picture. If your workshop space already exists, find a large piece of cardboard, wallboard, or plywood that’s about the size of the workbench top you envision. Find a couple of stools or chairs, perhaps a few books, and turn them into stanchions to support the “benchtop.” Is it too big for the space? Is it large enough for the tasks you envision will be performed upon it?
Remove the jaws and route the edges that you could not route while they were still attached. Then use a roundover bit on all of the corners except the inner edge of the inner jaw of the end vise. Give everything a lite sanding, and apply Danish oil to the inner surfaces of the jaws. (By "inner surfaces", I mean those surfaces that will not be accessible when the vises are assembled - the inner surface of the inner jaw, that bolts to the bench, and the outer surfaces of the outer jaws, that bolt to the vise plates.)
While $115 may seem expensive, try accurately boring a grid of 20mm holes on 96mm centers in 3/4 MDF. I have for a table for our retirement community shop - - its a pita. Plus the MFT material seems denser and more water resistant than garden-variety MDF. And the single-thickness has proven sufficient the last several years on my original 1080s. Still dead flat.
