I’m think of building a kayak, and I’m supposed to make a temporary table for glueing panels together. I cant find wide enough wood that fits in my car (a 4x8 sheet of plywood will not fit) (I looked at cheap shelving, anything wide enough is too long)
Idea 1 is to use a roll of kraft paper on the floor. (I need to use a chalkline to use for a straight edge) this is my backup plan.
the table is 5’ by 8’, so it’d be a bit different for 4x8.
essentially, it is a frame around the top, with 3 support legs - I used a “U” design (uprights joined at the bottom for rigidity), and scrap 1/4" panelling strips for corner bracing - construction adhesive and sheetrock [sup]TM[/sup] screws.
Standard length for dimensional lumber (2x2’s are sometimes mistaken for ‘furring strips’ - insist on finished lumber (S4S - smooth 4 sides), and a good working height is 34" - work out the design, and extend:
make three U’s for legs 2- 31", 1 - 48"
and a frame with three cross-bars for the top (EXTERNAL dimensions 48x96) the crossbars will be (48 - (2 x width of 2x2))
secure frame on top of legs, and slap anything moderately stiff on corners. Keep adding corner braces until it stops wiggling when you shake it.
Note:
the adhesive, which makes it easy to create a very stable table, makes it hard to dis-assemble. Your call (mine will require cutting to remove)
