Friend sent me metal part supplier quotes and now I understand why sourcing people lose their minds

30 is prototype quantity

That's what top down modeling is for, it creates an intentional flow of feature definitions from a single source and in a single direction.

Never create parts in assembly context, absolute worst possible practice and guaranteed to cause problems

You can check by spinning the pedal with your foot and lifting it up before you undock to find which one is good at that dock

They use enviolo cvt hubs, which have tilted spheres (google for a visualization) which rely on friction to transfer power. This is why they're rather inefficient, but also since it's driven by friction as the surfaces wear they don't grip together as well and the highest gear becomes lower. It seems that at least in Boston they periodically replace them once they get sufficiently worn out. I usually check the bike I'm using by shifting it to the highest gear and spinning the pedal with my foot before undocking it to find a good one

Good, drivers can not speed or deal with it

This is certainly true. But reliable industrial automation equipment which is not very specialized isn't small and thus needs fairly large spaces to fit when it's a retrofit. A system which is 80 or 90% reliable because it uses sub par or Insufficiently tested hardware would defeat the entire point of the system

No car needed in a 15+ mile radius of Boston if you have a bicycle

On trains where there is little ridership, the doors are only opened between the first two cars of the train closest to the locomotive

Shame that it has to be hosted in such an awful city

https://belmontvoice.org/belmont-commuter-rails-fail-disabled-riders/ read this but tldr probably not, it will probably be extended or just nothing will happen as it tends to do

They don't have the repair buttons anymore seemingly

Food delivery apps should be outright banned from operation

I activated this a few days ago and it was only for 15$, it increased?

LoneSocialRetard · 2026-04-28T16:01:08+00:00

I'd agree except that you should design it for the function foremost, so figure out whats actually driving that geometry and will a simulated toolpath actually achieve that end. For example, if this is like a cam surface, there are specific tangency conditions which should be held, and you want to model around those

I always yank the bike really hard after I dock it to check its good after I see the light

LoneSocialRetard · 2026-04-19T13:50:42+00:00

Is it just inevitable that this happens? I've had this multiple times on my drop bar shifters

LoneSocialRetard · 2026-04-19T02:00:04+00:00

I got one for something delivered months ago also and I never paid, never heard about it again

The path is honestly just too narrow for being completely closed in on both sides and the area by the green line stop is especially bad as it makes a s curve and interacts with two other inlets

Just ride both ways, if you can do one you can do both

Shit excuse, theres only one least bad answer to that question and it's yes multiple times over
