Last one we made was a triumph of engineering genius using a crowbar, a hammer and some nails. We pried all the planks off the pallets except for the most outerly ones, we then re-applied said planks with very small gaps between them. The result being 5 Heath Robinsonesque fence panels and some firewood. The panels were put together thus:

and the whole thing was carried across the garden to it's final resting place - this will provide entertainment for any neighbours you may have, or you might want to consider creating in-situ.
We had a couple of pieces of plywood at the front of each bay with a neat sliding mech (grooves) using some of the waste wood.
The closer spacing of the planks and the front bits kept all the compost in the bins and also prevented rats from nesting in them.
The excess wood got split as kindling and chucked in the wood shed where the rats had taken refuge
