Choosing
Stock
Next you'll want to choose your stock. Picture frames don't require a lot so
your scrap pile can often yield a treasure of possibility. Carefully match the
color of your lumber to the artwork or photograph, and mat. It's the mark of
a meticulous craftsperson and it's sure to impress. If your scrap pile doesn't
cooperate, there are dozens of wood
stock types available in all colors and textures. Tip: If you're really in
a hurry, you can use ready-to-cut picture
frame moldings.
Ripping to Width
Now rip your stock to width. Use 3/4" lumber (you can go thicker but it's
not a good idea to go any thinner), and rip it at least 1 1/2" wide because
anything less will look pale and weak--like you skimped. And you wouldn't want
to leave a bad Yuletide impression.
Using a good table
saw and fence, rip enough length to account for the full dimensions
of your finished frame, leaving an inch or so extra at the ends for good
measure.
Rabbet the Backside
Cut a rabbet in the backside of your lengths to accommodate the artwork, matting,
and backer board that will be installed in the finished frame. It helps to
envision the thickness of the stock in thirds, which is why 3/4" stock
works so well. The rabbet should be no shallower than 1/2" and should
remove no more than 2/3rds off the thickness so that there is at least a 1/4" left
to profile an edge on the front side. (See Illustration 1.) A 1/2" rabbet
or straight router bit will typically take a 3/8" width of cut. This
is a good dimension that will create a 1/2" by 3/8" rabbet in the
backside of your frame. Although your table saw can be used to cut this rabbet,
a router
table may be a safer alternative. Chuck a 1/2" bit in your router
table and rout the backside of your frame members.

The Front, Inside Edge
Choose the style of molding profile you want along the front, inside edge of
your frame. Since there is only 1/4" of stock thickness left along this
edge, you'll want to keep this profile within a 1/8" tolerance to leave
a strong enough edge within which to hold the frame's contents. Leaving anything
less will create a raggedy looking edge or none at all. The profile you choose
here should remove no more than half the wood fiber from this inside edge,
so it's important to choose the proper type of router bit. Bisecting the
edge with, say a 1/4'' bit will leave just the right amount of stock and
create an attractively dimensioned inside border for your frame. (See Illustration
2.) A cove
bit or classic
bit, for example, would do nicely. In working with narrow widths, always
use feather
boards on your router table. It saves fingers.

Front, Outside Edge
For aesthetics and eye appeal, a different edge profile works best along the
front, outside edge of your frame. If you've used a bead on the inside edge,
a Roman
Ogee, Classic
Roman, or Ogee
Fillet would look nice on this outside edge. Taking away no more than half
the wood fiber is a good rule for sake of both appearance and strength. (See
Illustration 3.) Tip: this edge can be profiled after glue-up, which sometimes
results in better looking corners.

The Back, Outside Edge (Optional)
As an option, you may want to also profile the back outside edge of your frame.
To maintain structural integrity and good appearance, don't remove more than
half
the remaining amount of stock from this edge should you choose this option. |

Miter Cut To Dimension
Once the frame members have been profiled to your liking, you can move on to
cutting your miters. Use this handy formula to get the total length of each
side:
[Length of Mat] - [width of rabbet]x2 + [width of frame]x2
Miters can be cut with a power miter saw, manually with a hand
miter saw, or at your table saw with a miter
gauge or miter jig set to a 45° angle (for square or rectangular frames). |
Trimming
to Fit
Dry fit your frame. If the frame members are cut well, they'll fit. If not, a
little trimming is in order. Don't be tempted to trim cut your mitered edges,
it could end up in disaster. Instead, lightly sand them to fit with a stationary
disk sander or use a miter
trimming tool. This will give you more control over stock removal.
Gluing Up
Glue up your frame using a good web
clamp or frame
clamp. Instead of standard yellow glue, a good epoxy is
best in this situation. It holds firmly against the end grain of the frame
members.
Let the glue-up set until the epoxy cures.
A Decorative Option
As another option, you may want to spline the corners of your frame. This is
a decorative approach to frame joinery that will be highly appreciated by your
gift-giving recipient.
The use of a contrasting wood for corner splines--a dark wood such as walnut
or mahogany--can further accentuate this attractive element. A router table
or table saw with a V-jig
or Tenoning Jig can be used to cut accommodating slots for your splines
along the outer edge of each corner. A 1/8" slot works well and leaves
enough room on either side for a balanced look. Most table saw blades cut a
kerf of about this size. Always cut the slots for your splines after you've
profiled the edges with your router, otherwise you risk routing into your beautiful
corner splines when you profile the edges. |
