Y why not? as long as you can get a 35mm plunge. 8 narrow slots - 2 in each face of a long piece of timber, isolates the corner blocks and leaves a centre core. Cut off the end so you now have 5 sections connected at one end - the 4 corner sections and the core. Take out the core with hand tools. PoP. And if you need more than one piece like this, cut them in pairs so when you cut through the middle of the routed slots you end up with two pieces.
