Default Torsion Box required

I have a large table. 36"X30". I do not wish to debate the merits of why I wanted a top that big but realizing others might also I suggest building a torsion box to support it if you do. The attached PDF shares how my top became a bowl. It also shows my top with torsion box installed.

A large top has just as many merits as a small one. Just different ones.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

2 ways to do a top without a torsion box.

I used 2 3/4" MDF 24"x36". I glued them together with the convex sides together. )(
This cancels out any warp.

Steel stringers between the pieces will stiffen up any top. Like the one I made for my RAS.

Bill,

There's no reason to apologize for your choice of router table size; mine is 30"x52". I chose that size for four reasons: (1) it takes full advantage of the capabilities of my fance, (2) it holds 2 routers, (3) it rests on a full-sized rolling base with *lots* of drawers for tool storage (which I *really* needed, and (4) I wanted it that size. <g>

I also recognize that others like much smaller tables; it's a matter of personal preference. What's best for one may not be best for all and everyone here is expected to respect that.

Mine was made by sandwiching 2 layers of 3/4" MDF between layers of Formica. A maple trim was then added. I've attached an old picture of it, before the base was built.

One reason for sharing was the MDF on first table. It had a factory finish which caused the cup after insert plate and miter slot was routed in. As the PDF said I belly bumped 3/4' ply w/the MDF

Not apologiaizing just avoiding the small top advocates. My reasoning was large panels will be more stable.. and an incra positioner as one of the fences (100 bucks craigs list.) Finally its in middle of the shop and in line with TS outfeed
