RE: bulkheads / baffles in secondaries

There are special blades for plastics/laminates that fit your jig saw.
They require a low speed so cut slow.  They also break easily(my
opinion).  Alternaitvely, I use my radial arm saw with a laminate blade
and rough cut the shape.  Then finish it to size with a belt sander.
You can buy a cheap fabricated table that fixed mounts your belt sander
vertically so you can work the part perpendicular to the sander on the
table.  Allows you to get the part to relatively accurate dimensions
without jumping up to a lathe.
