Here's a job I'm working on, the first Photo is of a very nice 3-d sign that was carved out of HDU, But it did'nt stand up, it actually came apart during a wind storm.. it was backed up with 3/4 plywood as well, anyway they wanted to keep the look of the old sign but had a budget to adhere to.

Here's what I came up with, it will be dibond printed on my wide format printer, but a portion will be 3-d.. I have Gemini letters here now that will be the Main copy.. so the background will be all fake 3-d and it will have raised Bright Gold plastic formed letters...The client Loved the idea... so yes we can Fake it from time to time....

Nothing fake about it Neil. It's 3D no matter how you slice it. Good for you that the other sign shop didn't know proper construction methods. An HDU sign should stand up to any wind short of a tornado or hurricane.

Well the guy who did the original is a really nice guy, and I'm sure he did what he thought was the best method... he does some awesome work and is in his late 60's.. so he has a ton of experience... he's basically retired now...But thanks for the compliments...

Nice sign... a shame! Neil, your's looks great too. You can't blame the HDU for trhis. Without seeing the sign myself, I'd think that the plywood was just laminated to the back for strength. Since HDU moves minimally from thermal expansion & wood moves mostly from moisture migration, there is no way to really laminate ANY material to the back that won't eventually fail. Gail force winds getting in between the HDU & the ply would make short work of the sign. I've learned this the hard way. To solve this problem, I put in insert inside the sign, completely encapsulated by the HDU, This insert can be made from almost anything that will hold fasteners. If you leave room for each substrate to move independently, as Dave says, HDU should survive gale force winds as long as the mounting structure holds.

Well said Deri. A lot of people seem to think they can treat HDU the same as wood & you really can't. Then they try to strengthen it by laminating without taking into account the different ways stuff will move. You can't build a bridge without expansion joints..... even dirt moves.
