Topic tags/keywords: workbench table saw outfeed

I’m just about finished with the router table that will replace one of the extension wings in my table saw and am starting to make the materials list for my next project. I would like to build an outfeed table/workbench, similar to the one featured in the Sept 2007 issue of Wood Magazine, that stores over the table saw when not in use as an outfeed. (click here for pictures & a video)

They use a single piece of 3/4” plywood for the top; I would like to add a vise to the end and some bench dog holes to the top. The questions I have are: 1) Would doubling up the 3/4” pylwood on the top be strong enough? and 2) Would I be better off using two layers of 3/4” plywood or would a layer of 3/4” plywood covered with a layer of 3/4” MDF result in a flatter/stronger top?

Two layers of 3/4” plywood would be more than twice as strong as one layer; provided they are glued and screwed together. I made mine out of 4 glued up layers, then put a MDF sacrificial layer on top, with double sided tape so it could be removed and replaced in the future. I set this bench under the main support beam under the house (my shop is in the basement) and set up a 30ton jack in the middle of the bench on a 3/4” steel base plate. I stopped jacking when the house lifted. The bench never moved. I was doing this so I could move a column in the way of my table saw, and also to test the bench. I think if I build another bench I will use two layers of plywood, covered with MDF. This one was overkill.
