IDK, I bought it from the closest store. The quality is good, but international shipment from them is not straightforward (local was ridiculously fast tho) I don't think I'd bother ordering from them from abroad

It is glued, obviously. Have I forgotten to mention it?

You can divide tip diameter by your piece thickness, and get arcsine of that value. Add that to your bit angle, and you get angle of each cut. But you'll need to test it on a scrap piece anyway, so it's easier to just measure it on that scrap piece. But I've just calculated, and this seems to add up. 1 mm tip diameter on 20 mm piece = 0.05 = extra 2.86 degrees = 8 cuts for 95 degrees instead of expected 10 for 90. And those 5 extra degrees spread on each cut are not noticable

And the bit itself has a constant angle, which would get constant angle for 1 cut if the tip was infinetely thin. In my case 9 degrees

Sorry, that piece of paper was really all my plan. Just use angles from wiki article, and sidewall that will fit your driver. Also don't make aluminum side, and maybe use mdf + veneers. Will make things easier

All the other parts, except for drivers are in description. One thing: the raspberry pi way isn't for everyone, there are issues, and I have to reboot it from time to time

We've had MS service center closing. So I've bought spare drivers from 502 I guess. Not sure those are sold anywhere. But there are online calculators for sealed box design, which I'm now a fan of. And you tend to get a lot of internal volume with this shape

Still wet. IDK much about glues, but there's a chance of water based glue having better adhesion/fusion with wet surface

Of course. Let me know if you find one

Like glued wood. Mine's a little dirty, glue melted when sanding. The gaps get bigger towards the face side, because the bit tip has some width

en.wikipedia.org/wiki/Regular_dodecahedron 116.6 degrees

There's 6 pairs of parallel surfaces. But this should be stiffer for same volume. Anyway I'm really happy with how it sounds. I think sealed box design is the biggest plus

I've bought mine here frezycnc.in.ua/category/251434/1102675 Mine has R0.5, but I'd buy 0.25 now. Site not optimized for international delivery, but it says they can do it.

Cool, let me know if that works. Doesn't the saw cut with it's tip only? On the other hand you could get an even thinner tip, if you have a custom made tool. Would look better

@@ivanmakes957 yea it seems the only way would be with a custom blade since there are no blades with teeth deep enough to do it im thinking of trying your way but using the circular saw with a thinner blade and not cutting as deep so the router bit doesn't have to struggle going through so much material and im pretty sure i can easily use the existing cuts with a jig on the router so i dont have to reset the straight edge for every cut with the router

That's a great idea. Router should folow the groove cut with a circular saw without a jig(maybe not any groove) And it is certainly easier to cut straight line with a saw

It's a carving bit

@@brubilucoteclado i'm try to search at Shopee and Lazada, I didn't find similar like that carving bit..

Where I bought it, it was just called "cone bit". Some guys on reddit said it's called "tapered endmill" or "tapered ballnose" in US

Yeah, carving. But there's a ton of different carving bits

@@ivanmakes957 thanks for your information.. Got it boss 😁

Hi. I did not really have a plan. Just cut smallest sized pentagons to fit the driver. And used all the angles and proportions from wikipedia article. Also I'd suggest to watch a youtube video on how to make pentagons (saw that after posting this) It's a good idea to make a jig for assembling. Also the aluminum side was a bad idea, all wooden sides would work better

That makes for a weak ugly joint. Fine woodworking is about doing things better.

But he wanted to talk about "a better way." Not the same ol' way.

Good idea

thanks
