Hi

Have someone experimenting using a milling tool in a rotary setup for engraving glass?

When I get my rotary tool from china I will try it out  :)

I have been trying to post pictures of my entry in the wine glass etching game. Each time it fails with an error code of 500. Individual pictures are about 1.2MB.

Try my resizer in my signature line.

They might be too large (pixels not MB)

@thorloki - Thanks but I don't have JRE installed and am ready to reload the base system so I just tried resizing in  gimp. Went to about 1/4 scale. Will try again to post.

Third attempt to post some picture of my entry in the wine glass etching game.

I use a low cost rotary table with a 3D printed spring loaded chuck. The prongs push outwards from the inside of the glass. The advantage of holding the glass vertical is it does not require support at the far end. The disadvantage of this design is I need a few different sized chucks depending on diameter of the glass.

The vertical (Y) axis is 8mm rods and a 4 start 8mm lead-screw. As pictured there are 4 linear bearings. The original design had just two but made considerable noise at certain speeds (600 mm/min). Have since learned that the bearings need to be worked in, especially with the cheap 8mm rods I bought.
