Today, we thought we had better build a quick “Home-made” foam board shredder so we can deal with all the millions of pieces of cut-offs we will be generating from slicing down the large boards. Many has unformed bumpy edges and other defects plus also there will be narrow strips left-over pieces as well. We always planned to “throw” this rubbish away under our suspended ground floor (we got 400mm of space to fill with insulation) but the random nature of all these cut-offs meant that it would be very awkward and annoying to try to get them laying down flat and reasonably efficiently connected together to form a good insulated barrier against the concrete foundations so we considered that it would be so much easier to shred this rubbish up and just pour it in like fluffy balls.
So we took our garden cultivator which had eight rotating blades, unbolted the handles and wheels, screwed together a new framework to bolt the motor and its blades to and then build a box around the whole lot to allow a large “ton” bag to hang underneath to collect the shredding.

We have to make some improvements as our tests revealed that the foam would get trapped in between the blades so that is the next task when we have a moment spare.
