I'm sorry for posting that drag knife thing.
I am bent on glue-chipped glass and thats what I always think of.
Etching is nice but I find that glue-chipped glass is more appealing.
Once my machine gets here i'm going to try it out.

As for the drag knife on glass, you could make some nifty
fills if needed and come along with the etching creams or
mask it for mini-blasting. Lots of possibilities but I may have
gone the wrong direction to the topic.

Anyways... either do hand masking or have it cut and you
could also use a mini sand blaster. Diamond Drag will ruin masking I believe.
Here's a cheapie using Aluminum Oxide abrasive.

Maybe I am going the wrong direction with CNC etching. I have had a local trophy shop etch logos into glass.
Recently the business changed hands and this has become too costly. Maybe I should be asking what is the
best way to make a mask.

Add a vinyl plotter to your arsenal for a mask. Im sure there
are smaller units out there you could pick up, load in the
vinyl mask, cut it, weed it out and start etching/blasting etc.
Xacto blades can do so much by hand and could get discouraging.
Vinyl plotters can only go so small before losing detail and alot of
stuff is small. Especially for trophies.

Are there other methods for super small graphics? Probably Laser?

Glastar has a neat mini sandblast system
that I've been interested in for years.

I make glue chipped glass by using rabbit hide glue on the glass....Old time recipe...

oK Michael.... spill the beans... err lets see.

Nothing like a glue chip and some smaltz on a sign.

What I'd like to know is how they can get a nice split within the glue chipped areas.
Theres like a nice inline to say that goes with the flow and chips out from there.

I know one thing for sure... my eyes are starting the fuzzies up close.
If I have to get any glasses... they'll be like George :nerd: Burns and I'm gonna glue chip em.

Wasn't the late Rick Glawson the guru of the glue chip?

If you want to go with sand blasting, look into Raysist Photo Mask. It's designed to contact expose which turns the part you want to keep into a sand blast resistant surface. It has a peel and stick backing, so it applies to the glass easily and peels off relatively easily after the sand blasting. https://www.rayzist.com/

Nice work Ralph.... that sorta reminds me of that guy Sam Alfano
who does metal carving on knives and the like.
Real wicked stuff.

Yea, Im changing the scene here. Goto igraver.com
There's p--p load of goodies, tips & tricks

I dont see why this couldnt be applied to cnc.
