Re: bulkheads / baffles in secondaries

Here's what I do, and it works for me:

Try going much slower with your blade....and use a continous blast of air
from your air compressor to help keep the blade cool...patience required.

Placing the parts in the freezer before cutting may help make longer cuts
before the heat takes over.
