Ok, I KNOW we're not supposed to use extruded acrylic, but that's all I had...

I did these etchings using a sled. To create the etch I determined how deep the centerline text would carve and then made the lines match up. I then "jogged to touch" onto the edge of the sled which was about 1/32 higher than the acrylic itself. This made the carve very shallow.

There is no filler/paint in the numbers- the bit leaves a white "residue" behind which works well to make the etch visable.

Every minute or so I stopped the bit and "flicked" off the gummed up "booger" from my bit. (the carves were only about 8 minutes long so no biggie)

I wouldn't recommend it- but just wanted to see if it COULD be done.

By the way, the rulers are nautical mile "scale rulers"- you use them to gauge "minutes from" distance for different speeds along a chart for navigation/etc.

Still cool. Whether you should have did that or not.

I have used a two flute 1/16 cutting bit to cut out 1/16 thick extruded acrylic and it was ok. I think as long as you do not do very much (no heat) it is ok.

I had done this from extruded plastic rod on the rotary jig, I stopped every so often a cleaned off the bit.
