You might want to look up the max thickness and other common issues hobbyist level laser welders have before purchasing, or at a minimum wait for the laser welders to mature a bit more. You'll spend less than half and be far better served with a cheap tig welder at this point in time.
I’m mostly concerned about the learning curve. The laser welders I saw can be used blindfolded and offer enough penetration. I noticed a lot of negative comments but mostly from people who spent years honing their craft and feel obligated to gatekeep it a bit.
There are some Youtube videos about homemade weapons in African countries and it seems you'd have to remove peoples hands in addition to their tools. Some of the functional guns out there are mostly hand whittled wood with a piece of pipe and some bailing wire.
I don't think its unreasonable to ask politicians to be familiar with how the machinery they are regulating functions and is used.
To use your heroin example, this is akin to banning spoons or needles because they heard those are tools of the heroin addict. It shows a lack of understanding on the part of the regulator and has a far reaching effect on people legally using the items.
My legs are long enough there isn't room for them to press against the back of the seat. I'm either manspreading into the crevases between seats or in foetal position with my knees halfway up the seat in front of me. A person reclining is excruciating in the former, but in the latter position at least the person in front can't recline as there's no physical space for my body to become more compact. Flying is hell.
Each material has its own issues. Kevlar is very difficult to work with (need special scissors to cut and you can't sand the finished product), Dyneema is sensitive to UV degradation. Carbon is $$$. Basalt sounds like the sweet spot for some of my applications but afaict it can't be purchased by the yard like most materials so is essentially unobtainium to a hobbyist who can't afford a $1k or so roll of material.
Exactly this. I make kayaks and basalt would be the perfect middle ground between FG and carbon where the boat will get dinged up in rivers. Unfortunately its nearly impossible to obtain in small quantities for a hobbyist.
It's a false equivalence to equate humans (even "super-recognizers") with a computer when it comes to matching large quantities of faces with names/PII.
At some point the numbers get big enough that you wouldn't be able to get the pictures of faces in front of the people who would recognize them fast enough.
When carbon fiber rims were new we still had not transitioned to disk brakes. You had to keep an extra eye out for misaligned brake pads to make sure they weren't dragging on surfaces not meant for friction contact. Now they make more sense. But also different loads on a wheel under braking than before, but also more like a wheel under acceleration, which is torsional force on the other side of the axle and pointed the opposite direction.
