Making a File Box – Part 3

Today, we are going to be putting the box together.  Seriously, this is simple to do.  The one thing I can tell you that is an absolute MUST is to have smooth cuts on your cardboard.  The pieces fit better when there are no wavy cuts or jagged edges bunging up the works.

Transform that box, in the photo above, into this box by following the steps below for the construction.

First thing to do is prep your work surface.  Whether you use liquid glue or a dry adhesive, such as Scor-Tape, you will need to have a containment area to keep all the gooey stuff from getting all over your table.  Personally, I like to use Freezer Paper.

Freezer paper has a slick side and a paper side.  The slick side will be UP, facing you.  Spread it out on your work surface and tape it down with some painters tape.

Get your supply of “structure strips” ready.  The adhesive you use is a personal choice.  Liquid adhesive or dry adhesive.  Doesn’t matter, they both accomplish the same objective…getting the strips to attach to the cardboard.  I prefer liquid glue.  Squirt some on, spread it around, then attach to the cardboard.  I’m all for saving time and being efficient.

Having to pull out a length of the dry adhesive, make sure it gets attached in the correct place, fussing with it and using a bone folder to make sure of good adhesion to the strip, then dealing with the paper covers.  Pulling the paper off the glue strip, containing the growing piles, chasing them on the floor because I missed the trash bag.  Then having no “Forgiveness” in the process.  When the dry adhesive gets attached it is there forever.  Liquid glue I can move the piece about to get it positioned right.

Round up your supplies

Fold one of the strips at the score line you had made and apply your adhesive….or apply your dry adhesive then fold on the score mark.  Smear out the liquid glue with a sponge brush then attach the strip to the bottom edge of the FILE BOX BACK piece.  That will be one of the 12 inch by 10 inch pieces.  Make sure you don’t put the folded area at the edge of your box piece.  Leave a small gap with the fold line showing.

It is vital that you get the adhesive out to the very edges of the strip.  Leaving a long worm of glue and calling it good is NOT good

Apply pressure and rub on the cardboard to fully engage the glued strip to the cardboard.  Turn the cardboard over and apply pressure along the length of the glued strip to ensure full adhesion.

If you need to add a bit of strip to a shorter length it is easy as cutting a piece to the length needed then glue it on, or if there is excess strip hanging off one side then snip it away.

Locate your BOTTOM piece.  This will be one of the 3 inch by 12 inch pieces.  Run glue the length of the exposed strip (or peel off the backing from the dry adhesive).  Smear the glue to the edges.  Butt the cardboard pieces together and raise the strip to be attached to the bottom piece.  Firmly rub the glued strip to get it adhered well.

Get another structure strip and apply adhesive to one half of the strip.  If using liquid glue, smear the glue to the edges.  Attach the glued side of the strip to the side of your back piece.  We will be building the side in this step.

Locate your next piece of cardboard.  One that measures 3 inches by 10 inches.  Apply glue to the strip and butt the side piece to the back piece.

Cut away any excess strip that overhangs.  Measure and cut a piece of structure strip that will go on the bottom and side corner.  Apply adhesive, attach the strip to the corner of the side and bottom.

Next you will further reinforce the seams of this box by doing the following.  Get a length of structure strip and apply adhesive to the entire strip.  Make sure the creased fold is facing you.  The “Mountain” fold will be up.  Work the folded strip into the joint of the back and side pieces of the box.  Press firmly all along the strip to ensure proper adhesion.  Set the box on its side and press the strip fully.

You will also need to reinforce the corner where the bottom and sides meet.  Do the same as above.  Apply glue to the strip, MOUNTAIN side, press the strip into the joint and apply pressure to adhere the strip firmly.

Following the steps above, get your other 3 inch by 10 inch piece and adhere it to the other side of the back and bottom piece.

Next, we will work on the FRONT of the box.  Locate your last 10 inch by 12 inch piece.  I am going to cut a curve at the top of this piece.

Find the center along the 12 inch width.  I am using a thing I don’t know what it is EXCEPT it has  a curve.  I have lined up the center mark of the curve tool with the center mark on the cardboard and traced around the tool.

The front of the box will look like this.

Back to the structure strip business to attach the front to the box.  Apply adhesive to both sides of the strip.  Making sure the adhesive goes all the way out to the edges.

Do the same to the other side of the box.  Make sure the edges butt up against each other as you apply the strip.

Look at this.  So far this is going along smoothly and is very easy to create the box.  Keep going….you are over half way finished.

The last part of the outside is to adhere a strip to the box bottom and front to close this up.

By now, you should have a good handle on how to use the structure strips.  The last thing to do is reinforce the inside of the box.  MOUNTAIN folds on this part.  Get the folded ridge pushed into the joints all over the inside of the box.

You can stop here if you don’t want to have a lid on your box.  The rest of this is how to put a lid and flap on, covering the edges, and making a cover for the curved edge.

If moving on to the lid.  Locate your last 3 inch by 12 inch piece.  Place it on top of the box opening.  If you were careful in your placement of the structure strips your box will be even and flush.  If you have a wonky box you will need to make adjustments to it now.  That will involve slitting the structure strips where the problem lies, moving the box to square, then reapplying structure strips.

Using the structure strips, attach the box lid to the BACK of the box.  Then attach the FLAP to the TOP FRONT OF THE BOX.  Doing this will make the next steps easier to handle.  You will be making a “Ditch” for the proper working of the lid and flap.

Check the fit of the lid

Working on the INSIDE of the lid piece.  You will need to take your structure strip to the score board and make another score 1/8 inch to the left of the center score.  You will have a “U” shape for this strip.  This is necessary.

Holding the lid in place, press the “U” into the joint of the lid and the top of the box.  You will need this extra bit of spacing to make the lid work properly.

Press the "U" into the joint of the lid and the top

Locate your final piece, the 2 inch by 12 inch piece.  Get another structure strip and score 1/8 inch to the left of center and apply the glued strip to the joint of the flap and the lid.  Make sure to apply pressure to strip on both of these pieces.

Your lid and flap should be working well.  The lid will not close fully at this point.  When you cover the box, or paint it, the lid and flap will be secured with a magnet or Velcro.

Apply structure strips to the outside joints

Now all that is left is to cover up the raw edges of the box and lid.  Gather your structure strips and take them to the score board.  Score 1/8 inch to the left of center on a whole bunch of them.  Measure and cut a piece of strip to fit one of the side edges.  Apply adhesive and adhere the strip to the box raw edge.

Continue covering your raw edges of the flap and the other side of the box.  We will deal with the curve in a moment.

Now for the curve.  Start with a long length of structure strip, crease it fully on the fold lines.  Place the strip over the front raw edge.  Note where the curve of the front begins.  Make a snip in the strip.  End the snip CLOSE TO the fold line.  NOT INTO THE FOLD.

Make snips along the length of the strip as you follow the curve.

Snip TO the crease where the curve begins

Make corresponding snips on the back side of the strip.  Remember to NOT snip into the crease mark.

Test fit the snipped strip.  Add any additional snips where necessary.

Liberally apply adhesive to the snipped strip then attach to the box front raw edge.

Apply the last bit of strip to finish off the raw edges.  Let this box set for about 24 hours for the adhesive to cure.  Even the dry adhesive needs a cure time.  You can think about what you want to do about covering the box while the adhesive cures.

I seriously  hope this tutorial has been clear and concise in my instruction and the accompanying photos.  I also hope that I have given you the confidence to give box building a try.

Are you ready to go and “Show someone how special they are”?
