Default Sign remodeling

I wanted to test a 3D file that will be part of a new sign design, so I decided to revamp an existing shop sign. The 3D element was carved out of HDU using a 1/4” end mill for a roughing pass, and a 1/16” tapered ball nose for a finishing pass. The character was painted with One Shot gold after priming, and then aged and highlighted with Teak Briwax. Brixax was also added to the existing gold letters and flourishes to give an overall old brass look.

Really, really nice work, Oliver! You are very talented and skilled at these - good job. Is the rest of the sign made of wood?

I still need to get some HDU and try this out one day.

HDU?
None of the acronym expansions I can find online relate to woodworking , except possibly "high density urethane" (a plastic.) Is that it?

That face is great. Constructive comment. It is so fine that the surrounding is too coarse by comparison. Perhaps you can embelish the surrounding elements a bit. Maybe cut a fine line inside the wider ones so you have a double line. Finer and more delicate.

You making good money at this? You sure as heck deserve it. Your signs are so professional you should be getting top dollar. Maybe enough to get an even bigger, faster machine?

The more I do, the less I accomplish.

Nice work as always Oliver . Did you make the 3D vector from a jpeg?

I don’t always insulate , but when I do .
Ok ,I never insulate

HDU is awesome to work with. It comes in various weight ratings, from 10 pounds per cubic foot to 90 pounds per cubic foot. It is a foam, but FAR more dense, and it has none of the characteristics of wood. Imagine carving a frozen stick of butter, or a large bar of soap. It is like that. HDU is closed cell foam, so it will not be saturated with water in rain. It will not crack or warp. It can be cut, glued, shaped, painted, etc. It is fantastic stuff for these types of projects!

The trade name is "Sign Foam" but it is sold under different names. HDU (High Density Urethane) is the way to go for CNC routing and carving.

Could you post that file of the professor here? I'd like to give it a go with my PlasmaCam table and 3D software, to see how close I can come to replicating it. The PlasmaCam is NOT meant for CNC routing, although it can do it. However, I believe the issue of the real difference between the PlasmaCam with 3D software and your table will reveal itself in the inaccuracy of the Z-axis. I assume that is about six inches in diameter?

I would carve it out of sign foam and post the results here.
