Warped HDU Panel
Greetings troops,
Here's a 10' sign panel Ron and I completed a couple of weeks ago. They we so impressed they placed an order for another one. But there's trouble! Last Friday I made a trip over to take some photo's and to my horror, the sign was warping! The sides had curled up a good two inches and the top was well on it's way for the same distortion. That spoiled my weekend.
Here's the problem. We installed this sign panel two weeks ago. It's made from 15lb Signfoam, which is extremely good, but I made the mistake of epoxying a sheet of DiBond to the back. That was down right stupid. The aluminum is expanding much quicker than the HDU. The result is a panel that's curving tword the front by three inches. I'm sure in a month it will be even worse
Here's my plan of correction. With the panel back in the shop I'll see if I can flatten her out and buzz off the aluminum back. Then I'll apply some 2"X6" cleates. What a mess.
Here's also a little double sided hanging sign. I'm making it from Cypress. That wood sands better than any wood I've used and holds detail almost as well as HDU.
