Passes at Glass
A couple of firsts today... First attempt to engrave glass and first job without the crumb tray.
The test article is a $2 glass bottle from Hobby Lobby. After measuring it, I propped it up on a piece of cardboard to get into focus range, and took a complete swag at the settings...
One side I coated with a bit of dish soap, the other I left unprotected. Can't really tell the difference.
These were svg vector engraves. Next attempt will be raster engraves with 4 "colors."
Jimi looks good anywhere. A metamorphosed limestone, I expect any calcium carbonate would react the same. Instead of micro-fracturing the surface like granite, marble is ablated. Like
@marmak3261 observed with Corian, I noticed tiny sparks - which turned out to be a very fine hot ash.
By the feel of my fingernail I would guess about a 100th" depth. The surface is bleached of all pigment and will receive color well. In this case trusty Krylon flat black spray.
What else do I have …
Button Escutcheon - Stargate
The ravioli rolling pins look good and helpful and I like the demo video at the top showing how one would work. Using Proofgrade 1/8" acrylic might do a good job for the slicers. Easy enough to put together over a broomstick. or thick dowel.
@mpipes looks promising but if you go ahead and make the lengthwise cutters as deep as the thickness of the round cutters and put them on the inside, when you slip it over the center dowel, everything will hold together without glue because the dowel will …
Glowforge Sizing Gauge
Whether I'm at a big-box store, a craft store, or even the local ReSource shop, I often ask myself "Will that fit in my Glowforge?" Usually, I've forgotten my tape measure and as cute as they are, I don't typically carry a Founder's Ruler with me.
I wanted something I could keep on a keychain or attach to my backpack, so came up with this.
The long axis represents the current maximum depth an object can have if you remove the crumb tray (1.5 inches thick + 0.5 inch for the current …
Our latest showers had us looking to make some flowers. My older daughter decided she wanted to make some paper flowers so she took to the web looking for how to make them. She found a few designs she liked and drew them up in Illustrator. The first one was a sort of folded spiral card design. The basic design was simple enough.
[image] It took us a few minutes to figure out the folding of it. [image] She added a bit of coloring and also tried a slightly larger version to take to school and…
I finally got the rest of my sorting trays done, and now I have a complete sorting system!
[image] Last night I played in the pre-release for the latest Magic the Gathering set, Amonkhet! If I’m building a deck (as I did last night), then I would sort by casting cost! [image] As a result of playing the tournament, I won some packs! Those combined with the packs I got in the pre-release pack means I have a lot to sort. To start, I sort by color! [image] Then, I would take each color a…
First and foremost, thanks to
@iliketomakestuff for the inspiration!
I decided to make my own, all laser cut of course! No glue, all press-fit, made out of 1/8" maple. I decided to use two layers of wood for all segments and used that fact to add a crimping element, to better seal the pasta!
(I broke some of the points off as I was pressing everything together)
And then it just so happened that a friend brought over some pasta, specifically to make ravioli!
Copics Organizer - FoamCore
Here's an item I actually made by hand with ruler and craft knife before I got my GF pre-release, and decided to do another in Fome-Cor (paper-backed foam board) before possibly doing it in acrylic. The idea is to have a place to keep my Copic markers on a shelf at eye level so I can just grab the one I want quickly. There is a slight tilt to each shelf so the markers will stay in place. (Note: this design is not unique--I've seen similar ones in Pinterest, but I did do the Illustrator work …
@cynd11 your wish is my command. I got some papyrus (god I love the internet) and attempted the papyrus squared challenge. The 1%/350 is still too hot, but maybe with the next lower-low settings we can truly engrave it...
Just finishing up a couple of test engraves on non-Proofgrade birch ply. The top image (John Snow's Cholera map) is straight from the web and the Star Wars concept art is from a photo I took at the Denver Art Museum last year.
Here are final results after removing the masking. The concept art has a really nice 3D effect that doesn't quite come through in this image, btw.
NB: the scorch marks are from a prior project -- I just used a piece of scrap ply for this test.
"I think I have never seen a 'forge as lovely as a tree..."
Okay, maybe that's not how the poem goes. Been a long time since I sat in Mr Klinger's American Lit class.
My daughter is wrapping up her first year at Elon University in Elon NC. A prominent feature of the campus and integral part of the school's culture is the oak tree. Every student is given an acorn upon entry and an oak seedling when they graduate. Lot of symbology and history surrounding the trees in town and around campus.
Battery Storage Boxes - Cityscape
Okay, finally carved this baby down to a manageable size.
(And since the various Proofgrades that we have to work with are different thicknesses, it took a couple of iterations to pull off the effect I wanted.)
I did away with the fancy insides and went with a straight lift the lid off and drop the batteries in....it uses less wood, and takes less time to load. (It's also a lot easier to build.)
I think it turned out looking a little bit like a building, so the continuation of t…
Camping on the Roof
Have never seen a slate tile roof in WV but somehow I ended up with a box full. Of course everything looks like a blank slate when you have a laser. Grabbed a broken tile for this test. Uploaded a simple drawing of my Xterra SUV and attached tent. Pressed Print. Slate does not accept shading very well and you should to be aware that the image will appear as a negative, but it works great for line drawings.
It was a super dreary weekend where we live, and because of that we ended up spending a good majority of the time indoors. So, in between episodes of "The Wire", I decided to make a few necklace pendants.
Since the cuts were close together, I changed the cutting settings to manual, and reduced the laser power by 5 percent and upped the speed by 5 lines per minute.
Two were made with 1/8" cherry hardwood, and two were made with 1/8" walnut hardwood.
Lasering Your Colon
So one of my colleagues who I do most of my research with is a color-rectal surgeon. He collects "unique" colon gifts, so figured since I hadn't lasered anything for him, it was a good morning project.
First off I have a very nice 3D model of the colon that you guys have
seen in my molding thread but figured it was time to laser that...
So I took it into Slicer for Fusion, now to do that I took the OBJ file into MeshLab and first decimated the model from 1m polygons, to 15000 (since this wil…

Stop Grinding My Gears
So tonight had to work on 2 prototypes for a set of "
what really grinds my gears" problems in the OR (crap falls on the floor, and somehow in the last 2500 years of surgery we haven't figured out a good way to have crap not fall on the floor - especially if it is hooked to a tube/wire)
So first problem was with the device called the "Bovie" named after Dr. William Bovie (it's also known as the Electrocautery) which is a RF arc knife/cautery that can either cut/cauterize or just cauterize. They…
Second Gear Degrinding
So the second removal of things that annoy us in the OR and pull stuff to the floor, is tube and hose management. Not rocket science, but after trying a bazillion devices out there, we decided to make our own (this is part of the project that the bovie holster I am working on belongs to) and so the idea is to be able to hold up to 3 suction lines and 3 bovie cables and maybe another "thing" that needs to run up or down the table.
Depending on which OR we are in the suction tubing might run fr…
Just spending a little time doing some testing on the 1/4" acrylic that I finally was able to break into usable size for the Glowforge. In the photo, ignore that deep score across the top on the back sides of the test pieces, that was just one of my unsuccessful scoring attempts, not the laser.
Anyway, besides the fact that engraving on acrylic is really awesome, I thought folks might be interested in a different material for color infill. What I'm using is different colors of pati…
OK, not to build it up too much, lol… Now, this pic doesn’t really do it justice; the light I was using isn’t that bright, and it’s a bit blurry. It looks so much better in real life, but at least it gives an idea… Shine a bright light on the face of it…and display the shadow onto a wall::
[image] Look at that face! Sorcery! Plus, check out the pretty border, created by the flashback from the crumb tray. Again, it’s blurry here, but it looks really nice in real life… Sooo…
Since getting a PRU, I've mentioned more than once that I'm experiencing a bit of a learning curve. For one thing, I've never used a laser before - and while this forum has taught me an awful lot about that, I still have a lot more to learn. Another factor is my lack of experience with design software. I often use Photoshop to edit product photos, and I've used Corel and Powerpoint in the (very distant) past to create beadwork tutorials - but I don't have a strong background with graphic design …
I got started on a build for that Grid Purse that I posted a while back, and adjusted for the actual thickness of the material. (So the one I shared is off, unless you can find material that is exactly 0.25 inch thick.)
But it was also a test of the results of the Slicer program for Fusion 360, and I'm sorry to say, I don't believe it did what I think it should have done.
The program placed a couple of unnecessary cutouts where they weren't required (due to the smaller size of the actual ma…
Creating Geometric Patterns
I was looking around at some old Japanese patterns for inspiration and was a bit entranced by one I found that seems to be called asanoha. I'd definitely seen it before on different things and decided to see if I could come up with a good rendition of it for the laser. I started with a hexagon and then made some additional lines to section it up. [image] after that I traced out the triangles I wanted to work with as separate objects (green). [image] Then I took those and did an offset path (bl…
An Unkerfed Clef
There have been a bunch of great posts on Inlays using the Glowforge laser cutter. Wanted to try an instrument head stock inlay that I have attempted before, but found impossible (for me) to do by hand. Have a buddy that works at a veneer company so I have access to a lot of different veneer scraps. Unfortunately, don't know what was used here. Looks a little like Padauk.
My stock veneers are extremely thin, 0.02" or about half of the Beta Glowforge veneers with masking. …
So first of all I have to say that I am not an autoharp player. I only started using one so I wouldn't have to sit on the sidelines at the old-time fiddler gatherings we go to. I know nothing about chords (my usual instrument is a wind synthesizer), so I learned how to read my husband's fingers on the guitar and press the right button at the right time.
So we bought a decent looking used instrument a few years ago and my husband completely redid the felts with a chord layout that is most c…
Cutting Thin Fabrics for Applique Work
Feliz de Laser
So tonight we answer two questions, can you and should you, because some of you are I am sure, tempted:
Yes and No are the answers. Mostly because it doesn't smell like popcorn or grilled corn... smells like leather which had rancid corn spilled on it.
So the good news is the flat bottomed taco shells are pretty square so fairly easy to set up (and more importantly my wife has the evening shift, so she didn't see this) obviously you have to remove the honeycomb, with a 0.4" above focus depth…
Purple Heart Inlay
I know, you're thinking it's Henry, it will be some snarky anatomical pun on heart since he did cut into a real heart today... But nope (well I did, but that's not this - although I did leave the title in 2 words to make people wonder).
I stopped off today at Rockler today between my two anatomy sessions, and decided to get some exotic stuff to try something artistic.
I hear you cry: "What,
@henryhbk be artistic? That'll be the day". I will have you know I have a fine sense of art, and like…
Eat More Chikun
Seeing some of the cool earrings and leather projects folks are turning out made me want to try the critter burning myself.
It's been a long time (as in decades) since I've done any serious leatherwork but I'm jazzed. Wifey will love them. Ran to Michael's for some earring hooks and loaded up a nice little design in the laser.
Fire in the hole! Proofgrade settings for the 1.5oz PG I had in there resulted in serious cooking of the cow epidermis.
Switch to manual and dial up the speed and po…
With all the SG1 folks here the acrylic edge lit portal escutcheon button ring & overlay has been done to death :stuck_out_tongue_closed_eyes:
Having been there & done that, I figured I'd take
@marmak3261's Mexican discovery (Mayan Sunstone) and turn it into my Glowforge's Big Glowing Button.
Not knowing how it would translate to acrylic (see my previous post for a wooden coaster comparison of the Calendar and Sunstone designs), I tried with some 0.118" clear cast acrylic I had in stock. I …
Movin’ on Up
Photo engraving - check. So easy to drop a file and print to you know what. :sunglasses:
Looking at all the talent on display here, I began to feel humbled by the works of all the other PRU's. Since housing one in my shop, with a mass of materials at my disposal by the grace of glowforge - I find myself waking up at 5:00 AM. (she's like - "Are you OK?") The education has been continuous, and I find myself filled with impatient optimism. I satisfied a long standing desire to throw away an eyes…
Mitral Valve Leaflets
A new prayer group has formed in the parish. There was a commissioning service last weekend. We gathered together a kit for each of the members to assist them in their ministry. They got a nice swag bag, a brochure for guidance, several prayer books, several prayer cards, a cool prayer journal (with the double spiral bound but the cover was already pretty cool to begin with), a cross and a candle.
Here is a version in Proofgrade acrylic. The cross is seven inches high and the frictio…
Another Glowforge Meetup
So Friday, I got to meet with
@dwardio at the Colorado Plastics 4th Friday remnants sale.
We got to look and touch at different selections of materials. He and I both got a selection of materials.
As part of the trip, he invited me to experience (:squee::squeee::squeeee:) a GF :glowforge: up close and personal :sunglasses:. I had not been that giddy in a long time.
Needless to say, :love::glowforge::love::heart_eyes:!!! It is beautiful and much bigger than I thought it was (gonna need to reth…

Prerelease Trace Test on Cardstock:
I thought the symbol would make a great drink coaster. Maybe cedar? What's a good wood for a coaster?
A horn I made using leftover sections of another group of instruments I was working on.
Decide to do a little exploring while a silicone mold was 3D printing for an experiment, and figure out what the workflow for a laser cutting project from OnShape cad which isn't the "slightly painful right click SVG export for a face", which works for a couple of parts, but after a while gets absurd.
So first off made a little laser cuttable box using the "Laser Joint" FeatureScript plugin:
One complaint I have with most laser box makers is they fully tab the box, requiring you to…
Just following up to share my experiment with this. It basically just confirms what others have already said or shown, but here it is for posterity: Yesterday I engraved this little bee design on to a scrap of 5/6 oz proofgrade. I tried to follow along the engrave line with a bevel stamp, but my first attempt (right side) nearly sliced it clean through with just a couple of taps. I took it a little easier on the left side, but even so, the effect was more like a cut or a slice than a traditio…
I have been fascinated by sacred geometry for a long time. It was peaked recently when watching an episode of "The Curse of Oak Island". Here's a cool video explaining how the forms are obtained. I want to make some of these on the Glowforge.
I have the Delrin but no 20 ton press. But at least this shows how to do it!
Published earlier today on Hackaday:
Two points that I heartily agree with:
You can never have too much material
Never, under any circumstances, walk away from an operating laser!
I did a cursory search and couldn't this posted before. If so, my apologies.
I learned about
Retro Built Games today via the always great Maker Update video blog from Maker Project Lab. Ryan from Retro Built Games makes sweet arcade games in lasercut cabinets. He sells kits but there are plenty of free plans and files on his site. Highlights include:
Found this today and thought it was an amazing video and could inspire some fantastic designs.

Customized Print Button Escutcheon:
Here is the design I used. The file has three circles that are cut. The outer green, the glyphs and the inner blue are printed on 1/4" Proofgrade clear acrylic. The separate red circle is printed on 1/8" blue chemcast acrylic from Inventables and becomes the blue acrylic cover for the button itself. I don't have @takitus image manipulation skills to get the water effect, but I'm working on that. It would be cool to e…
Thought I would share the latest updates. I still have the final sanding and finishing to do, along with adding all the lines, straps, etc. But the end is in sight. These are photos of cutting out and gluing hatches.
[image] [image] [image] [image] No finish, and the hatch covers are off, but I wanted to see what it looked like by the water. [image] Here are the hatch covers. [image]
