||Safety Glasses, Drill with 7/16th bit, 4"
Grinder with Dewalt .45 cutting disk, pencil, and speed square.
Later, we'll need 4 - 4" L-Brackets, 8 -Strong ties for
sign corners, 16 - 2 1/2" bolts, along with washers and nuts.
All the hardware comes from Lowes Home Improvement Center.
||Your going to
need steel tube. In Ft. Worth you can get steel tubing from Lowes
but for the money, you might be better off checking with your
local Highway Department and ask them to sell you a 12ft stick
of 1 3/4 inch of perforated galvanized steel tubing. If not ...
Lowes carries perforated tubes.
|Sign Blanks. We order our
blanks out of Dallas and get free delivery. They come
painted white but for the purpose of this tutorial we used a
black panel. Another good source for sign blanks are Real Estate
offices. Many Real Estate offices will have signs they don't
need or the realtor quit. Ask for them. Make sure their steel and not aluminum. If
you only have aluminum, then use
Magnamagic paint. Paint
them and your ready.
This next step is the hardest. The Sign
Blank I used is 24" x 36". My Tubing is 1 3/4" inches. The perforated
holes in the tubing are1" center. 2 pieces will be cut 23". 2
pieces will be cut 38 3/4". The two 23" pieces need both ends cut to
allow for 2" centers. To do this, measure 7/8" inch for the center of
your last holes. You'll see why this is
important later. Look at the pictures below.

Corners are Simpson Strong Tie. Lowes carries them. You will need
2nd image shows pilot holes drilled 2" centers. A speed squares
flat base (if you
have one) is exactly 7/8" of a inch wide. If you don't have one, measure
7/8th of an inch from the inside of Simpson Strong Tie then mark a straight line
with pencil, drill your pilot hole then finish drilling with 7/16 drill bit.. Click for larger image 2. **
Using a clamp speeds up the process to do 2 corners at a time.
Next thing to do is cut the slots. The 23" tubes are cut
down their centers end
to end. The 38 3/4 tubes, leave the last holes uncut. I
used a 4" hand grinder. I have table mounted equipment but for these
small jobs I found it was just faster, easier to run the grinder down
the middle of the holes. Dewalt makes a metal grinding disk just for
cutting steel. One disk cost around .69 cent and will complete this job
and probable another. Anyway, take a straight edge and
mark the centers of the holes. Cut the center slot making sure you don't cut the last holes
on the long tubes. ** If you do cut the last holes it
won't matter but I prefer not to. Either way, it will still work and
If you've attempted to make this simple sign, you have come to
realize how easy this actually is. The really good news is the hardest part is over. All that is left is inserting the sign
blank into the slots, attach the corners, bolt on your feet and the sign
Fabrication of the sign is self explanatory. Sign fits into the
slots, corners bolt on each side held together with 2 1/2" 3/8th nuts
and bolts, and feet can be attached.
Lay out your sign first. 23" inch perforated tube fits inside the
Slide your sign blank inside your tubes.
Assembling the larger sides first is the easiest. Laying a couple of
blocks under your blank helps but assembly can be done without. Use 3/8th
nut and bolts, a 9/16th wrench tighten the corners. Checking for square,
tighten the 4 center bolts. The center bolts are what clinches the sign
together. Make sure the center bolts are tight.
Attach your feet if your needing a sidewalk for street sign. You can
use L-brackets from Lowes.
Changing or moving the L-brackets to different mounting points is a snap.
The corner strong ties on 2 inch centers and the L-brackets come
with 2" centered holes. I hope you found this useful and it help you if
