We're looking for best practices and tooling for doing a better job at etching score lines and engravings on our casework.
These score lines are just a simple line drawn to indicate something like the top edge of where a fixed shelf needs to be located, or occasionally something small like a part number engraving.
We are doing this on 3/4" melamine and 3/4" prefin plywood usually, but could be on any material you would make casework out of.
Material thickness is a real concern here, no matter how diligent we try to stay on coding to our actual material thickesses, there's enough variation that you can go from "no engraving at all" to "grand canyon" in a hurry.
We own an aggregate which we use for V-grooving on MDF and it does a wonderful job, however we really don't like the idea of keeping that big aggregate just for a small engraving bit. We normally leave it uninstalled just to keep the weight off our tool magazine since 99% of what we route doesn't need it.
Are there any smaller, lighter weight devices that can give us similar effect to what a larger aggregate does? Something light enough to remain on the tool magazine indefinitely but always indexes from the surface of the material?
