Here is something different.

An old bowling alley.....hardwood, 42 inches wide and as long as 20 feet in some cases. Build a heavy duty frame to set in on, cover with insulation board (if you like to build on a soft surface with pins).

Cover with glass if that is your preference.

Cover with a thin sheet of steel and use magnets to hold your work while you build.

My building board is chip board (osb) 4'x8' cut in half lengthwise. This serves as a top and bottom and are screwed to a 2"x2" frame to keep it square and straight. Then it is covered with insulation board and placed on a cabinet base or frame of your choice.
I'll look for a better pic to post.
