Beyond the weight capacity, the Grizzly is also the largest table top on our list and in more ways than one. For a workspace, the Grizzly provides 5’ of length by 2 ½’ of width. There is not another table that really comes close to that size. Another size advantage of the Grizzly bench is the table top’s thickness. While the standard thickness of the table top for a quality woodworking bench is 1” with lesser models often offering only ¾” of thickness, the Grizzly provides a 1 ½” thick table top.
The original design had a height of 35-1/8". Their two-layer top was 1-1/2" thick, so their legs were 33-5/8" long. I want a height of 35", but I'm using a top that's 3" thick. My basement floor is anything but level, so I'm using levelers that are adjustable from 3/4" to 1-1/2". In other words, I want legs that are around 31-3/4" long. (If you're not using levelers, your legs need precise lengths. The levelers give about 3/4" of adjustment, so precision is less necessary.
When the holes were complete, I flipped the legs and drilled the countersinks with a 1" Forstner bit. Trying to drill a countersink when the center was already drilled would be impossible with a spade bit or an auger, but Forstner bits are guided by their edges, not their center, so they can handle this job. On thing about Forstners, though -- they have a tendency to skitter around a bit when starting, before they bite. An easy fix for this is to drill a hole through a piece of ply, and to clamp that to your work, creating a jig that will prevent the bit from drilling in the wrong spot.
@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.

The best way to use this article is to visually break the furniture piece down with reference to the categories listed. On a piece of paper, write down the main focus or core of the piece and place it beside the project. With a critical eye, question whether all the elements support the main goal. Ask why you have designed it this way. For example, if the main focus is to have a comfortable chair, you might want to consider which lines, texture or colours visually inspire people to think the chair is comfortable and stable even before they sit in it.
The engineering involved in building this garden bench is pretty simple, and we have provided some links to get a full cut list and plans with photos to help you along the way. Additionally, to the stock lumber, you will need wood screws, barrel locks, and hinges to complete the table. A miter saw or hand saw is also extremely helpful for cutting down your stock to the correct angle and length.
