Try using a pulse DC for building up weld, something very slow so you get basically a series of tacks. Adjust the timing and duty cycle through some trial and error. Since the gas will keep flowing it should keep things clean.

If I were making claims about 10 million cycle stability I would be much more confident if I set up a test rig to do one cycle per second and let it run over the weekend. "I fixed all the issues I found when I ran it for 2% of my max cycles target" sounds a lot better than "eh it seems to work when I try it by hand". Sorry 😎

Hey Martin, just a heads up, continuing to pursue a perfect failure rate will push you over the critical point of optimal functionality. As changing variables continue to be added, the machine’s functionality will start dropping from that asymptote. I know you want the machine to be perfect, but the pursuit of perfection is not a graph that ebbs into an interminable extending asymptote, it’s a parabola. Once you reach the maximum, thats it. Also the felt is probably not the best option as it won’t be durable over time and will likely compress - changing find tuned resistance.

You could test this though, make one with a simple return mechanism for the marbles like a test rig, leave it running dropping two marbles a second for 60 days, that would be 10m marbles, see what has worn after that time and improve the design.

I you glued the felt strips only at the ends and in the middle then you could put card shims under the felt. That would also give you the possibility to regulate the mechanism when the felt compresses. Piano technology.

Felt will always compress a bit in time. It would be good to consider simple regulation mechanisms wherever you put felt.

@wintergatan, You should file down the end of those bolts into a point. Not only will it make it a smoother rolling surface and reduce friction but it also: 1) Make the marble roll down instead of laterally, completely solving the problem of lifting the marbles above it 100% of the time. 2) Lowers the chance of the marble getting stuck against the flat edge of the bolt if the gate tries to close too fast. Thumbs up if you agree with me!

I still think there's a better way to meter the marbles than what is being used here. Instead of displacing the marbles on their path, they could be kept in-line of the desired path and a part that moves into the path would provide interference to stop marbles from moving. If you think of the marbles as being like teeth on a wheel (and forming a natural gap to the sides of the marbles that the mechanism can fit into), then it wouldn't be too hard to design the path for them to work with an escapement mechanism of some sort. If this current setup is still prone to failing or tolerance issues, then this other method may offer some gains in reliability and precision.

Not trying to be mean or something, but i feel like martin is falling back into old habits of hacking stuff together to make it work instead of planning ahead and figuring it our before making the final part. For that reason i am afraid he is working himself into a corner that is impossible to get out of. For example when he modified the parts using the offset tool instead of properly redesigning the part. Do that 3 or 4 times to a part and it is now completely messed up. It feels like he is dodging the dragon instead of fighting it.

All the engineers in the comments: but what does failure even mean‽ Me: At the outset, he said he was worried about marble jams in the release mechanism. The most obvious effect would be the muting of a half-channel in the middle of a song, which constitutes a critical performance failure, to say nothing of any knock-on effects.

You're missing the point and context of their question. He hasn't specified whether he's talking about critical, machine breaking failures, a missed note, or a jammed channel. He's also been using the same words "10,000,000" and "failure" over several videos taking about a variety of parts. So your reply isn't complete and is packed with assumptions.

Would it be a good idea to widen the gate holes toward the front a little so that, even if the felt wears down even more over time and the gate lands further back, the marbles will still be able to fall in without issue, even if they do end up lifting the next marbles a bit?

Add felt on the back of the shuttle and keep the shuttles tunnel slightly offset to the front. There are a lot more felt mass on the back and that way you don't even need the felt in the other areas. edit: also since the felt area is larger it compresses less which means the shuttle isn't sensitive to the "extra pressure" scenario tested in the video.
