How to Cut a Perfect 45 Degree Angle to Make a Picture Frame

[Music]

picture frames are all around us hung on

the walls of our homes and businesses

the artwork and historical pictures that

occupy these frames emulate our diverse

culture and stimulate our imagination it

seems to me that frames play a unique

part in the overall look and feel of a

picture or a piece of artwork hello

there my name is William Andrey I'd like

to welcome you to shop fix a community

joined together for the love of

woodworking today we'll learn how to cut

perfect miter cuts for picture frames

stick around

an essential part of cutting a perfect

miter is to make a clean cut without

chipping or splintering the wood to

achieve this I recommend installing a

fine-toothed finishing blade you can see

me here checking the saws alignment

because the most important aspect of

cutting a perfect miter is to align your

saw blades so that it cuts in the exact

45-degree angle if your blade is not

perfectly square with the fence you'll

want to unmount the measurement

mechanism on your miter saw the d walt

models have a semicircle metal plate

that's mounted with 4 bolts you can see

me here on mounting those four bolts so

I can move the plate

[Music]

now you can properly align your blade

with an accurate reference square if you

are more comfortable aligning your blade

at zero degrees instead you can

certainly do so once the alignment is

correct

lock down the position of the sauce that

it doesn't move as you screw the

measurement mechanism back into place I

[Music]

want to thank you for tuning in to this

episode of shop fix if you've enjoyed

this content so far hit that like button

let's continue by ensuring our frame

boards are completely square so that we

can cut precise miters and assemble them

flush now we are ready to cut our first

45 degree miter ensure that the angle is

proper before cutting and rest the board

firmly on the miter fence and cut slowly

length is not a concern for us on the

first two miter cuts the important

aspect on this next mitre is to cut in

the correct direction so that the

adjoining piece will fit as you planned

now with your first two adjoining miter

cut you could check for proper fit and

begin to measure and mark for final

length to ensure your miters have no

gaps once the picture frame is assembled

it is critical that you cut the top and

bottom pieces the exact same length you

will want to do the same process with

the sides to achieve this I recommend

creating a 45 degree stop block so that

it does not come into contact with a far

corner of the mitre as the corners have

a tendency not to be a hundred percent

the same length

once the 45 degrees stop lock is mounted

in place you can cut the top and bottom

frame pieces to final length be sure

that you hold the side that is wedged

between the stop block and the blade

because unlike the other side this piece

could kick back

to finish cutting out the frame you will

simply repeat this method for the left

and right side frame pieces if a stop

block cannot be used or it's too

cumbersome with your setup I recommend

cutting the first piece to final length

and matching the inside length and

marking as shown here

as stated before it using the far corner

as a reference is not as accurate as the

inside corner because of how the miter

saw cuts once you have measured and

marked that position on the other piece

you can begin to trace out the 45-degree

angle onto your board as to accurately

align your blade to the cut line it's

important to note that final cuts have

to be precise as there will no longer be

any length left in the board to correct

an error so measure twice and cut slow

and steady let's head back over to my

workstation so that we can begin the

final assembly of this pine frame if you

utilize any tips or tricks that I've

missed comment below so that we can

share them with fellow woodworkers

this particular pine frame needed no

further prep before gluing because of

the accuracy of the miter cuts you will

save a lot of time in the shop by

measuring out Myers and cutting them

precisely with no chip outs

once you've assembled your frame pieces

and have checked for proper fit and

alignment you could begin to glue up

your frame I currently utilized the

Bessie bang clamps as I find them very

easy to use however a picture frame

clamping jig may be more accurate but

does take some time to build I really
