Stained Glass Lamp with Mitered Corners

Some of you may remember the teaser I posted a few days ago about miter cuts on the Glowforge. I finally scraped together enough “me” time to finish the project. I’ve been working on it a long time! (@marmak3261 saw parts of it when he visited last week). First, the finished project, then I’ll show the progress photos in case anybody is interested in trying something similar.

Total height is 4.25" and the “stained glass” panels are 2" each side including the walnut corners. This tiny lamp is an exact copy of a full size one I made that stands about 10-11" tall and is made of real stained glass. The design is my own.

Here are the two lamps:

I cut the stained glass panels from white Proofgrade acrylic, and engraved the lead lines. While the material was still masked I smeared on some Heidi Swapp Metallic Black embossing paste and let it dry. It looked a lot better than one I tried with the leadline applicator from the stained glass paint set–less gloppy. After it dried I pulled off the mask and painted the flowers and leaves with stained glass paint.

I got the walnut 1/8" square dowels at the local craft store but I could easily have cut them on the Glowforge. I cut them to size and glued them in place with Epoxy330 and a miter clamp. That was tricky, let me tell you!

Speaking of tricky, here is how I cut the miters: I created a jig from scrap maple plywood that consisted of a right triangle with two 45 degree angles. Here’s what it looks like:

The tall piece is the piece of Proofgrade 1/8" walnut hardwood to be miter cut. It leans on the jig at a 45 degree angle and the laser cuts straight down on the edge (by lining up a cutline in the GFUI visually, with the cut placed just below the camera):

So with miter cuts in the Glowforge, you can make the sides of a box as tall as the length of the bed, but you are limited to only about 2" on a side (about 2.3" before miter cutting) for each side. Fortunately that worked perfectly for my little lamp.

Here’s all the parts (not including the “glass”):

The mitered exterior really fit together nicely:

Put it all together. The stained glass part rests on the engraved shelf in one of the square pieces, and the little plastic votive fits tightly without gluing into the circular holes. Here’s a look down the top:

And the underside:

If you try something like this, I advise you to cut the mitered box first, then you can adjust the sides of the square parts to fit it; it’s a lot easier than the opposite way.

It looks great! Thanks for all the details.

I really like how you made the jig for the bevel cuts, too.

Wow…I’m speechless…that is incredible! Not only very creative, on both the mitre cutting and the painting, but the design is simply beautiful!


#4

Extremely clever :slight_smile:

The only change I’d make is using a bit of aluminum foil to wrap the piece that you’ve got being sacrificed under the laser beam. It won’t burn up and you won’t have a chance that the beam will eventually burn thru to your triangle support.

Awright! Awright! Awright! That is simply awesome! :grin::+1:
(And the most exciting part is the mitered cuts, which I’m looking forward to trying soon.)

But that pattern is beautiful!

You never cease to blow me away! You are so talent and skilled. What a beautiful lamp!


#7

WOW! Simply amazing!


#8

Once again I am in awe of the talent here.

Every time I step away, I come back to more amazing content.

So beautiful - the miter trick is fantastic. Thank you for sharing this.


#11

incredible… I am blown away.


#12

Absolutely beautiful!! And extremely clever jig!!
Thanks for sharing.


#13

Truly stunning!


#14

So very, very neat!


#15

Very beautiful AND creative!

I planned on trying out that same miter idea myself. Looks like it works as well as I expected! Trouble, of course, is Z. So who’s got the basic math skills to tell me how long a piece of material can be at 45° at the 2" Z limit? (I have a few talents. Basic math doesn’t make my top 100.)

2"x square root 2 = 2.828"
Diagonal of square = 1.414 x side length.


#17

Thanks!


#18

Keep in mind that the thickness of the cut is also 1.41 times the thickness of the material!


#19

Good point!

Darn! I always get bummed when someone beats me to any math.
