Government don't have the right specs. I deal with municipalities all the time. They are absolutely clueless for the most part. Colorcore is heavy stuff. You're going to want to find someone local to do it. Literally anyone with a 4x8 CNC should be able to do the job. Centurion tools makes...

This is another case of someone giving specs on materials and but they don't know what they're talking about. You could replicate that sign out of several different materials. Colorcore is a very good recommendation. Using 12mm PVC and color filling is also another good recommendation...

You're going to need to use a filler and then sand smooth.

You'll most likely want to run a metal frame around the sign. Then weld an attachment point onto the steel. The only other method I know of it to literally drill through the sign. Insert a threaded rod and at the bottom of the sign have a nut/washer/steel plate which you attach the threaded...

Calling up Rowmark will give you a hint whether or not the material is available. After that you need to find an engraver. You can find 48x96 lasers around. Most are designed for cutting primarily but some will serve double duty. It shouldn't be impossible to find, but it won't be easy...

Have you contacted your material supplier and asked if they offer CNC routing services? Many do. I've contacted a few and most are reasonable and one of mine was VERY inexpensive. This is coming from someone who owns their own CNC. As for material, I don't do this type of work but I'd...

I have no intention in discussing this further with you as I've already proven my point by posting the MSDS and by you illustrating how different people have different opinions based on different things. In the end, as long as the product works and the customer is happy and the bills are paid...

My opinion is the project is flawed because front surface vinyl signs in a hospital setting are going to fail earlier due to the constant cleaning. I would recommend engraving, applied letters, or 2nd surface vinyl. But that's me and my business. You can do what you want and in the end...

All that matters is that you and your client are happy. Personally, I'd recommend going to 12/13mm white PVC/Sintra instead of MDO. Although the material is a bit more expensive, you're production time should drop a good amount, especially if you needed to do a decent run.

Thanks for the feedback thus far. Some interesting thoughts on everything. In response to a few of the questions/statements: Kottwitz-Graphics: The goal is to offer an alternative to calling up someone like Harbor, Grimco, or Gemini. There are times when those companies don't fit the bill...

Let me first preface this post by saying I'm not soliciting business on here. I'm simply looking for advice. I own a 4x8 CNC, decent sized laser cutter/engraver, small laser cutter/engraver, and some other equipment many sign shops don't have. I'd like to offer my services to local sign...

I recently did a 2 month "internship" at a shop that had pretty good routers that were not maintained with terrible vac hold down. Here is what I learned. 1. Turn on the vac table no matter how badly you think it's performing. Every bit helps. 2. Cut with a small bit. For smaller letters...
