Re: [bolger]
You can cut a curve with a skill saw, just don't over
extend the blade, the further it projects the flatter
a curve it may cut. Also the more vertically the
blade returns in the cut, which emphasizes tear-out.
Frankly I don't think anything you do with Luan will
eliminate tear-out, and make it ok just to plunge
ahead. When cutting across grain, I use a sharp knife
to score the plywood and ensure tear-out does not
cross the line I am cutting to. This works well
because the tear-out rips the surface layer back to
the knife line, which makes a very clear line against
which to conduct subsequent fairing. Luan is marginal
marine ply. If properly handled, however, it has
achieved USCG ratings in charter cats.

I appreciate the low cost of the material, but I have a few
observations/questions:
The wood seems to have almost a gloss which makes it sometimes difficult to
use pencil for marking, and to see the marks after they are made.
Surface sems almost brittle when cutting and prone to slivering.
I need some suggestions on sawing to a curved line using a 7" skilsaw. Will
the 7" skilsaw blade make the curve easily? I usually end up doing a lot of
sanding after the fact. Perhaps the answer for this one is to build the
Teal and Zephyr whose sides have no curvature.
Would appreciate some practical onbservations on the use and working of
Luaus ply. Thx.
