Just do one viral thing somewhere once and believe my own experience you'd regret an unproperly shielded identity. People can be violent for no reason

I like your brass parts, usually orifices are made of polished metal to avoid catching the material. The main issue people have, is that they don't realize what they see online has been made by individuals with solid skill sets and machines. You can literally whittle a Saxony wheel with a knife, but that means weeks of work for a skilled whittler... Those wooden things are technical objects of a more complex design than most think about.

Find some local spinning lessons those will help, and even bring your wheel to a local wool fair to let others try it (and who knows if a 40 something guy with a kid make the local spinners do weird noises cause how thin he spins you probably have me in front of you!)

Oh and one last thing Arthur: protect your identity please! Reddit can be a rough place believe me I mod a lot of subs, please be smart and keep your name away from it.

Honestly I get why most people don't share much info... The one I designed for myself was made using my spinning experience and years of 3d printing and machining knowledge. I was nice shared everything I could and received thousands of emails from people not even knowing how to use a screwdriver willing me to make one for them or sell them one becoming harsh or insulting when I told them it was a complete no way! People don't get a project is not a product, they don't get that even if I was up to sell it, a fair price would be way more than established brands because prototypes cost more and even more when you fiabilize them for regular use. They don't get that selling or giving something like that is definitely complicated cause it has not been désigned for a classic push button use but your entertainment and knowledge and you love when it breaks or causes you an issue because it's the goal!...

Well I removed all my info like a lot of others due to all that, and yeah that sucks but I'm just human (but you can dm me of you have questions though!)

If I was doing it again I would iterate an already existing design to avoid the wild bunch

Yeah that's a very cool project you launched here, if you just wanted to spin, not the best route, but I doubt you'll go through that if that were the case. I hope not too much people without any mechanical basics will ask you the plans or if you can make one for them🤣🤣🤣 I know first hand those can be legions. Pro tip if you post it on thingiverse do it on a dedicated account and not your main one...

Most double belt systems are propelled with vegetal fiber belts for that exact reason. Linen and hemp singles are a common choice, finger spun seamless nettle rope seems to have been a very common choice amongst Europe even 50 years ago.

You really should consider lower that friction, cause you sometimes need to adjust your spin by letting the bobbin slip... And yeah friction heat will bite you, it's the curse of several modern wheels actually. On old timers the flyer groove is v shaped to increase that grip and the tensioning one is u shaped with sometimes a little crown to increase slipping.

Those Chinese little things are so delicious compared to mid-high range stuff I bought second hand when I had my shop a decade ago, but be careful not staling it too much, they really seem poorly équiped on the thermal protection side...
