Beta project(s) eleven - experimental edition

The spirals are of great interest to me as parts of acrylic clocks. Not power springs, but for regulating. Your experiment was a great success. Also liked the box.

Nice! I really like the spiral!
Now a question, not sure if you are allowed to answer it, or if @dan has to. The chipboard, is it Proofgrade™?

Way cool! I am wondering whether some kind of Peano Curve (or something like it) could make a good living hinge. There are probably some rules you could give a curve-making algorithm to get something that would work and also look really different.

I’ve done a little playing with scroll-saw spirals, and it seems you need vertical thickness to be seriously greater than ribbon width. This is also a situation where extra axes on the laser head would be useful, because if you could tilt the cut you could make the whole thing self-supporting with just a little glue.

Well, that’s not how you spell piano - oh….

Haha. I swear I spend half the time I’m on the forum just googling all the things I don’t understand. At least half the time. When it’s a technically, sciency, engineeringy discussion, it’s literally like every other sentence.

I have tons of new ideas for the spiral. One is a spiral wood or side lit acrylic slinky used as ornaments.

The material we’re providing Josh is all being considered for Proofgrade inclusion but is in various stages of development. The chipboard is from one vendor but isn’t anything very special (unlike e.g. the 1/4" plywood, which is custom fabricated and has the protective coating).

Oh, and @jkopel, so you don’t have to waste all the hardwood… you basically need plywood or MDF to make a living hinge. We have many splinters in testament to this. :wink: If we didn’t get you any, let us know and we can fix that.

Nice experiments Josh. Thanks for the time to document. The spiral bowl does have promise. Common as a wooden fruit bowl. Perhaps possible with flipped cut to get a thicker material that is registered well.

Ya I had thoughts of making these bows as well but typically I see them at 3/4 - 1 and from my under standing we only get 1/2 with flip. Does anyone know because the focus is more than that if we could multi pass and actually get more then 1/4 on one side? Thought is make two or thee passes to get 1/2 flip and do it again? Crumb tray removed with proper standoffs most likely needed

So glad to see you’re able to experiment and post beta projects again… I missed them.

It’s great to see these experiments, both successes and failures. Thanks for putting the effort into do them and then reporting on them.

Or acrylic too :smiley:

It’s not about avoiding horizontal lines in general, but about avoiding cross-hinge lines in living hinges. You can cut plenty of horizontal lines in other projects.

If you use a cross-hinge line in a living hinge, you’ve basically created another, extended, rigid area in your hinge, and it won’t bend properly. In the OP’s test, as the part was cut horizontally, cross-hinge also runs horizontally.

I’m not the OP, of course, but I have a laser and I’ve cut many living hinges. I do have a Glowforge on order, as well.

+1 to being able to make random boxes. I had done a couple projects as gifts for my SO’s parents (the christmas ornament was one), and we were leaving the next morning to fly out when I realized I didn’t have boxes for them. I was still at work and debating trying to find a late night arts and crafts store to get decent boxes when it hit me that I’m sitting 10 feet from a Glowforge and I can just make one. I whipped up these two boxes using your friendly local box generator and some imaginative shaving of tabs in illustrator in about 30 minutes, less time than it would have taken me to go to a store that was probably closed already anyways.

The best part: no glue required! (Yay for understanding kerf!) I made the lid piece a smidge smaller to allow it to be removed easily and just tied some plain string around them and presented them directly, and they can be used forever to store the gifts in.

looks great.

Nice work @Kusmeroglu! I think I saw that design on Showforge I but didn’t know what it was going to turn into. :slight_smile:

Is it safe to assume most veneers (since thin) can use a living hinge as well? I’m thinking of the walnut veneer wallet madebynick made back in January (speaking of which we never got the update on durability from him…)Today’s Project: A walnut veneer card wallet

The veneer needs to be backed by something. My walnut veneer watchband’s been holding up great!

A lot of veneers come backed, which is nice for initial work. But do they even require a living hinge? (across the grain, I guess)

I warned you about small pieces and padauk!! :wink: “Fragile” is not Italian. hehe

Are you still liking it?
