Our understanding of what makes pleasing proportion is deeply imprinted in our mind and of all the design elements is the least influenced by one’s cultural experience. Desirable proportion has long been based around ratios we see in nature with an emphasis on the human body. The “golden rectangle,” considered to be divine proportion, has been used since at least the Renaissance period in art and design and has largely influenced our common experience with architecture and design. In fact, we often don’t even see proportion until something is out of proportion.
2 - use a plunge router with a bottom bearing cuter bit such as this from rockler: http://www.rockler.com/product.cfm?page=25160&site=ROCKLER .... I thought to use the short one as I plunge it directly downward in the centre of the hole until the bearing reaches within the tabletop hole. I suppose one could use a long one, but the stubbiness seemed more practical (the big bearing ensured accuracy?)
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.
