First thing worth sharing

Made an edge lit sign with my wife’s photography logo. Used a diamond drag bit. Took 4 hrs to do the engraving but it was nice a quiet lol. Used a base from amazon for $5.

Dude that’s sick! Is it just a light engraving on the surface of some acrylic?

Yes Sir. its a 1/4" diamond drag bit i got off of ebay…

a little spindy for a single bit but man it was nice watching it run and being able to hear myself think. it takes a while because the line it engraves it so small. i had it set at .1mm for the bit thickness and a 10% stepover. i think i can safely pick up the speed a little but i errored on the side of caution and let it take its time. the base i used was cheap on amazon…

So when you say drag bit does that mean you don’t spin it at all? I assume so because you say it was quiet. The notion seems foreign to me though.

Correct. The router just holds it. It has a spring loaded diamond tip. it just “drags” along the surface of the acrylic and engraves it. technically you could do the same thing with a spinning bit much cheaper but with this its quiet and if there are any variations in your table surface the spring action in the tip makes up for it. i set up for a 1.5mm DOC and got a great finish.

I did something similar for my brother (30 of it) and ship down to Brazil…


He added the logo sticker and built the holder with the led strip

Looks great! I’m curious what the difference in finish would be using a drag bit vs a spinny bit… I’m thinking the drag bit would come out nicer.

Hopefully this works. First time trying to post a video. Anyways. It’s the drag bit in action making a sign for my daughter

Looks great! Someone at work just threw out some acrylic, so there might be some of these in my future!

I might try to use Ryans’ drag knife set up now, seems similar with the spring loaded mount?

well the audio worked

yeah im working on it now… any better???

I can see the video now, not sure about the audio but I’m on mobile right now with no headphones on.
