AIM TOOLBOX: Dremel Micro Review for Glass Etching

IMG_2839

From 2014-2016 I chronicled my crafty endeavors on the site Adventures-in-Making. I’ve selected a few of those DIY’s, Recipes, and other posts to share on the site.

I have a secret. I’ve been hoarding glass bottles… and jars. Sure, I’ve been drinking out of a set of 6 jars, but what no one knows is I have a whole box of them in my closet.

Shoot. Now you know.

The big plan was to use etching cream to mask and etch them into glass masterpieces– but something always stopped me. It may have been that the first time I pulled out the etching cream, Safety Husband insisted on reading the ingredients and warnings. He then set out a strict list of suggestions for using the DANGEROUS stuff I got from the craft store. I followed the suggestions once, but lived in fear of getting out the cream ever again. I had the PPE for it, but even so, it was a little scary. “Wear gloves. You don’t want it eating through your skin… to your bones.

We live in a world of excess caution, over here.

Safety Husband recommended safety goggles and a respirator- talked down to spectacles and a dust mask.

The box of glass lived to taunt me. Sitting in there, instead of going to the recycling bin where it belonged; until I got the bright idea of looking for alternate etching options. There are a lot of great, videos, but the one from Dremel sold me. It was time to replace our old rotary tool, so after some shopping I decided on the…
Dremel Micro, which is cordless.
•I bought two diamond bits, but I’ve only got around to playing with the one that looked most useful, the Dremel Diamond Wheel Point Bit.
** UPDATED 12/14 – I’ve since started using two different diamond bits with more success. 7105 Diamond Ball Pointand 7103 5/64-Inch Diamond Wheel Point

Experiments

I tried several different ways of getting my initial artwork laid out, including drawing the design on with a Sharpie, as well as using masks that we had made with the intention of using the etching cream.

Tara Bliven drew and cut out this beautiful mask for me.

We drew and cut these masks out of contact paper, but you could also use masking tape. They are a great way to start out, because the mask will help you learn to control the tool. Thankfully, this is a cordless dremel tool so you don’t have to worry about the wire tangling whilst you’re trying to follow the guide. If you jog out of the lines, the mask material will shred before you mark the glass, giving you one chance to screw up without consequences.

The mask is definitely the most time consuming and tedious way to go. I’ve moved on to freehand patterns, and occasionally use paper templates that taped to the other side of the glass. (More on that later.)

Tips

•Higher Speeds (controlled with a button on this model) work much better for etching glass. I usually use the second to highest speed. The highest works even better, but the sound is skull-splitting, so I only use it when absolutely necessary.
•Using the bit I’ve listed above, you will mainly be making thinnish lines, so plan on going over your artwork a couple of times. It works best to hold the bit as close to parallel with the surface of the piece.
•Make a jig for round items. I took a couple of wood scraps and made a kind of rail for the glasses to lay in. (See in the photos above.) Make sure it’s small enough to move around, as you will want to be able to approach your piece for all angles. After my experiments, I sprayed the whole jig black so I could see my work more easily.
•Wear Protective Gear… or you’ll get in trouble. I found a dust mask and glasses worked for me, but it might be good to start out with even more coverage, so you might want to look for personal protective equipment to suit you and the job you’re about to undertake. Remember that your glass could shatter at any time.
•Start with thick glass pieces, and don’t grind too much in one place. This is not a tool for drilling, so you’re more likely to shatter your pieces than cut cleanly through.
•Start with trash pieces you’re not afraid to throw away. There’s definitely a learning curve.
•Hand-wash any pieces, to make sure you’re not shocking the thinned glass with hot water.
•Work outside. You’ll be generating a ton of dust. While I haven’t had any sharp pieces (yet) it’s nice to let nature get rid of the dust.
•This is a no-distraction project. Don’t plan on watching TV while you work with power tools.

Things to Love

•It’s lightweight. Initially I was planning to use a flex shaft like they use in the video, but the cable is not very flexible, and I decided the lack of cord would be a benefit.
•It compact and easy to transport (although it does not come with a carrying case.)
•The battery lasts longer than I do. I haven’t had to stop what I was doing to recharge.
•I haven’t hurt myself (yet). This is always remarkable.

Things to Hate

•The “Lock” button sticks out just above the power button, and I have hit it accidentally a couple of times while the Dremel is running. It makes a terrible sound to tell me I’m killing it to death.
•It’s still a little clumsy. Even though the end is tapered so you can hold on to it, it’s more like trying to write legibly with a Squiggle Pen than an actual writing implement.
•It is quite tricky to get make a curve. A lot of this has to do with skill, and the kind of bit I’ve been using.
•The sound, especially at higher speeds. It makes a high keening when you’re using it on the glass. The birds have been complaining about this as well. It’s just life in the etching game.

Things to Try

•More bits. I tried scratching the glass with non-diamond bits with little result, but now that I’m hooked on the etchin’, I’m going to try everything. (If you have suggestions, I’d love to hear from you.)
•More freehand designs.
•On flat surfaces, like plates, trays, etc. On mirrors.
•Make a set of matching glasses, with patterned numbers, using paper templates. That’s pretty specific, huh? I guess a DIY is in the works… but until then, have fun!

  1. I’m going to try this! With you! I just want to write LUQUILLO, PUERTO RICO on some little glass bottles. I will trade you bottles for a 1-on-1 next time you’re etching, if that’s ok??!! I really love the D glass you made for Dave.

  2. The Silicon Carbide Grinding Stone(The blue ones) are good for big areas and save wearing out your diamond bits. You can also use buffer pads for lighting up what you have already done (good for creating shadow effects). You will (If you haven’t already) fine that you can get different grit diamond bits. Mirrors are also good for etching, as well as metal, it’s endless the fun you can have with it. Even candles I found out after my wife restricted my use of anything in the cupboard. Try some wood relief carving.
    I’ve been having fun with this for a while now and my wife is affraid she will wake up one day and find the windshield on her car etched over.
