I had a real challenge working my first flex face sign, this lighted sign had a 3M PanaFlex face stapled into a channel in the Aluminum frame. The channel groove was about 1/4" wide and 3/8" deep.
I had several challenges, fist being I was not able to locate the 3M PanaFlex sold by the foot, so I opted to use the 20oz Cooley, I purchased 3' of 10'-6" wide material, just enough to do this job.
Next was the challenge was to pre-install the graphics on the Cooley or wait till after the face was installed to allow for better placement and alignment, I opted to go with the second.
I had to figure out how to staple the Cooley down into the channel, thanks to "wayne k's" lead on Signs 101, I downloaded the
Milliken Matched Component Staple System, and it showed the use of special clamps. I recognized them as being welding clamps and remembered seeing them at Harbor Freight, I needed about 6 clamps at least to force the Cooley down int the channel before stapling. I purchased the welding claps at HF, and they did the job, however I had to modify the bottom of the clamps because the small convex dimples would mess up the front of the flex face.
Next, I tried all my current 18ga stalpers, had both a Paslode and a Craftsman, neither nose would fit down into the channel, so I purchased a cheapo 18ga stapler at HF, knowing I would have to modify the nose section just for this application. I removed the safety-trip device from the nose and then it would fit down into the channel. I would have to pull up on the safety latch under the trigger each time I fired a staple, it worked.
Without the safety-trip device, I had no way to adjust the depth of the staple, in testing I found the staple was penetrating the Cooley material (bad), so I had too figure out some way to keep the staples from penetrating the Cooley. I had a roll of 1/4" clear vinyl tubing that was just long enough to go around the perimeter of the aluminum frame. I made a few tests, and it worked, the the clear tubing offered just enough resistance and protection, and the staples didn't penetrate the Cooley material.
I noticed that the old 3M PanaFlex material was stretched across the long way first (maybe has more give), then the short sides were fastened. So, that's what I did, first stapling one end stapling the clear tubing in the channel, then on to the other end. I used two flat welding clamps on the Cooley fabric, and used long adjustable clamps from the mid support to pull tension on the fabric. I didn't have any other way to pull tension prior to stapling.
Now that the flex face material is installed onto the aluminum frame, I get to figure out a way to block-up, support under the face so I have a hard surface to install the graphics. At least this way I can control the placement and position of the finished graphics on the sign.
I hope all this can help someone in the future.
Thanks to all here at Signs 101 for your HELP, I could have never got this far without suggestions!!!
