A Trick to Sawing Compound Angles & Odd Shapes

Saw compound angles

Shallow kerfs laid in on all of the sides.

The trickiest minimize when constructing a chair or stool is leveling
the ft. This minimize is all the time a wacky compound angle. And when
you mix a compound angle with a foot that’s an odd form,
such because the octagon proven right here, it may be troublesome to maintain
your noticed in the proper aircraft.

Right here’s how I do it – it’s a technique that has but to fail me.

Lay out the minimize you wish to make on all of the sides of the leg.
I take advantage of a mechanical pencil so the road is a constant width and
simple to see.

Making this minimize is so much like drawing a line within the sand on the
seashore. For those who draw a shallow ditch within the sand along with your
finger, the ocean will comply with that ditch as a result of it’s the path
of least resistance.

So consider your noticed as water.

Make a shallow kerf (about 1/16” deep is okay) on all of the leg’s
sides or surfaces that you could see. Don’t fear concerning the
surfaces you’ll be able to’t see as a result of they face the ground. Attempt to make
these kerf so they’re all in the identical aircraft (that aircraft will
finally symbolize the ground that your chair’s ft will relaxation
upon). But when your angle is off a bit, don’t fear.

Joining two facets.

Becoming a member of two sides.

Joining the kerfs on two more facets.

Becoming a member of the kerfs on two sides.

Now you’ll be able to deepen these kerfs barely. Maintain the noticed on the
appropriate angle for the minimize and noticed down, becoming a member of the kerfs on
two sides. When your sawblade reaches the corners of each
sides, cease sawing. Transfer the noticed to affix the kerf you already
made with the shallow kerf on an adjoining aspect.

Ues the deeper aspect to information the noticed as you be a part of these two
sides. Once more, cease sawing if you attain the nook of the
subsequent adjoining aspect. Proceed this course of till you’ve got
joined all of the sides you’ll be able to see.

After kerfing all the facets you can see, use them to steer the saw to complete the cut.

After kerfing all of the sides you’ll be able to see, use them to steer
the noticed to finish the minimize.

Now it’s time to belief your structure and your kerfs. Begin sawing
down to complete the minimize. The kerfs throughout the leg will information
the noticed – they’re the trail of least resistance. So long as you
don’t attempt to steer the noticed, it’s going to comply with the kerfs.
