So, great minds of the Carbide 3D Community, I am getting ready to do a large sign (4x8?) carved logo. Just a flat shape no paint, nothing. I would prefer white PVC (?) maybe(?) Or some thing along those lines. Thoughts on what material and how to handle it? It’s going on the side of a corrugated metal building. Now that I have some sweet tiling skills I want to expand my portfolio!

The obvious thing is a bar at the bottom and a semicircle matching the arc at the top for the logo.
Something like:
(but with better proportions and margins)

If the client allows, I would lose the HOA. Owners know it is, no one else cares. That with what Will suggested would be a balanced design.

Silly me, I was thinking cullasajahoa was a Hawai’ian word…

An alternate treatment for that text would be to make HOA much smaller and stack the letters vertically (if the client is inclined) — that way it’s present if it’s a legal requirement, but could be made the same vertical size, while still keeping it subordinate.

The purpose is for location of their building to differentiate it from the Cullasaja golf course building, so the logo needs to stay as is.
So far all great brainstorms!

So the customer requirement is no color? I’m not a signmaker at all, but I’ve watched some neat YouTube videos about signs made from Color Core. No painting, just route and the color is laminated in the material…

You might need a crane to lift a 4x8 sheet of
ColorCore😊
PVC is great and machines well but you may have to hunt for a
Sheet that doesn’t have wood grain on one side, unless of course you want that look. It’s MUCH cheaper than the HDU you are used to. If you need to glue it, just use regular PVC glue and be very fast.

I think “CULLASAJA” should be centered under the logo and then HOA (same scale as it is now) should go below CALLASAJA and centered. That gives the entire sign a centered look and balance on the bottom that matches the top logo.

That sign will look like a white cow in a snow storm!

Purchased a sheet of KingCore white/black/white. Going to be delivered next week…with another sheet of HDU. Looking forward to trying another material.
I don’t know if you saw my post in another thread about ColorCore but when the central color is dark I was unable to get nice looking pockets with the OFlute bits. They left a hazy looking surface. It was great when wet but when dry it just looked dull.
I use a #102 endmill and 8000 rpm. Do some experimenting on it to see what you like. I use the OFlutes for through cutting and maybe profile on the line type cuts.
Here are the settings I use:
Yes, it is slow Typical advice on the plastic stuff is slow RPM and fast feed but after all my testing this is where I ended up. I also am using a raster path rather than offset.
For finer detail I add in a 1/6" bit (and sometimes smaller) using REST machining.
It is pretty soft plastic so forgiving, but not as forgiving as the HDU.
I would say to pick a chunk of the material and make some small pockets like 1" square with various bits and settings to see if you can hone in on something that you like.
If the central color is white or maybe light tan the haziness in the pockets is not noticeable.
