With this type of manual pipe cutter, it's going to take far too
long for the OP to make the hundreds of cuts they need. And
electric chop saw type machine is probably going to be the best
that pipe cutter will take too long plus additional work will be
necessary to ream and de burr.
i make jigs for repetitive cutting…metal, wood, clay…it’s kind
of a given in the fabrication process.
maybe they could contract the work out to a few people…to get the
quantities they require.
