Title: glass cutting or etching
Post by: sparkyengle on July 02, 2010, 10:55:46 AM

Does anyone have any info on etching glass on a wood router? I was possibly thinking of trying it for kicks.

I suppose it depends on how much cash you want to spend on your kicks  ;D

I would think the easiest way would be to cut a stencil with your machine stick it to the glass and then lightly sand blast the for the etch (not on or anywhere near the machine  :)  This is vinyl but there is a special stuff made for sandblasting however for light blasting the vinyl works well.

Or you could perhaps add a laser to etch the glass directly.

This is just two options but I am sure there are plenty more. Hope this gives you inspiration.

Thanks for the info Tweakie! What type of set up did you use for the vinyl cutting?

Made my own cutting knife then any vector toolpath can be used for cutting the vinyl. It's perhaps not as quick as the purpose built machine but it makes just as good a job and it can still be used for routing wood.  ;D

btw. The ready made vinyl drag knives are not that expensive to buy now-days (made in China of course).
