I know of no simpler, cheaper, or more convenient method to clamp up edge joints than the luthier’s technique for joining guitar tops and backs. Though intended for thin wood, the technique is easily adaptable to any thickness, width, or length. All that is needed are several long wedges, a few 1x2s (longer than the work is wide), and a length of ¼-in. rope.

When the work is ready to be glued, lay it on the 1x2s as shown. Tie the rope to the right-hand stick and weave it over the work and around both ends in a figure eight. The diagram below shows one figure-eight loop for clarity but several are necessary. Moving to each 1×2 in turn, repeat weaving the figure eights, tying off the rope on the last stick.

Now insert the wedges under the middle of the figure­ eights and drive them home with a mallet. This will apply clamping pressure without danger of the wood buckling and damage to the edge. Wax the wedges and 1x2s to prevent their being glued to the work by squeeze-out. The whole process is fast, but it’s advisable to practice a few times to get the hang of the rope weaving.

Here is a video by luthier Beau Hannam that demonstrates the technique:
