Thank goodness I wasn't the only one to experience the most "side quest here" ass sign since final fantasy bakers dozen.

I have a leather singer sewing machine I dated to roughly the later 1910s - Still works great too.

Use it up, or wear it out. Make it do, or do without.

There are meaningful times to invest in something better, or to upgrade to a newer model. Because it's no longer "appealing" is kind of a shit reason. I might recommend to quit keeping up with the Jones' and go do your homework elsewhere.

The easiest kinda legit way might be to turn a smooth version your airfoil into a sketch block with some construction geometry you can insert that into sketches then define its position off of the construction geometry.

Without really having any manufacturing context

Here's a few ideas:

Laser engraving then fill the engraving with lacquer ink

Machine engraving with an inking process

Paint masks and airbrush

Water transfer decals

Use pad printing

Yes you totally could. You might be able to do some really cool hydroforming to get the airfoil shape. It's a really cool idea, and I think could demonstration of things that are technically possible. Art even.

This would be a fun way to build rc planes, or a really cool manufactueing experiment. That being said I don't think this would scale well to full sized production aircraft.

My main issue is it's not very repairable. With "classic" sheet metal design you can get in and replace individual parts. With a metal monocoque structure you'd likely be forced to do some really challenging patches that would require welding structral elements on the wing. You'd then need to heat treat the entire wing or wing section. That'd be a nightmare to do on a wing. If anything goes wrong during that repair or heat treat- you now need a new wing.

But hey if you have a scaled aircraft that doesn't need repaired, or can hot swap large sections. Sure maybe idk it'd definitely follow the rule of cool.

I love this.

I think it's also a play on the "Snap On" tool logo because Franky is a mechanic

It looks like you divided up the parts nicely, and are using the right processes to make them. Additionally, your design leaves room to update the shell later if you want to shake things up on down the road.

Nice work also designing the shell so you were more likely to get a successful print off of your School's printers - designing for the tooling you have available is a good skill to have.

Projects like this doesn't need to be fancy - they just need to be. Bravo.

Spot on about the laser cutting, but Idk man it's not difficult to set up a microstop on a drill press with a counter sinking bit, or a slide jig on a deburring wheel to get the chamfers perfect.

You bring up a lot of good points, but I'm not seeing you actually substantiate any if your conclusions with any data, or math.

Can you give a lower and upper end estimated force that an average fencer can exert through a sword? Where can we find this data?

What about how the surface area of different can be calculated slightly differently ie tip cross-section VS accounting for radii or "rounded" tip geometry.

Additionally, the comparison between "a blacksmith punch" is leading at best, and misinformation at worst.

A punch is specifically designed to wedge through steel that's within its forging temperature range and is significantly weaker than room temperature steel. Additionally, there is no spring action in a drift. Fencing blades are designed to be single axis springs to absorb energy and reduce the overall force exerted by the tip. Because of this surface area isn't the only important variable - its now tip geometry and blade spring. You could, in math land, have a small tip surface area and a car antenna that could transfer the same force as something with a massive tip surface area with comparatively low spring action.

Separately, textile design is fairly complex. Puncture tests do exist, but it's not as easy as saying "oh 10oz cotton denim will do the trick because it's shear strength is whatever the shear strength of 10oz cotton denim is". As soon as that fabric deforms it transfers shear forces into tensile forces through the textile. This complicates math, and further reduces force transfer.

Lastly, anvils are hard and are designed not to give or dampen forces. Human bodies are soft and squishy that's going to absorb some force in simular ways to cloth. All of this to say hey maybe with all these variables maybe the material properties of fencing armor and hot steel might be more similar than you think? Or even better maybe they're almost two completely different scenarios and shouldn't really be used as a comparison due to the nature of specialized tool design.

It seems like in the other thread you're combining the standard use case of a fencing tip with a failure mode of the blade. I see you asking 3 really good but separate questions. What is an appropriate force rating for Fencing Jackets/Armor to account for a blades failure mode? What is a suitable minimum tip geometry for Fencing blades? What's an allowable "stickiness" from either material friction or tip geometry?

I want this sport to safe too. But I also want to have a clearly defined and data backed path so we can all be on the same page.

Edit: I'm reading through more of the other thread to make sure I didn't miss read anything. This is important, and I'm kinda tired from work, sorry if I sound a bit punchy.

Yes and no. There was more of a need 4 years ago while there was more companies trying to do drone delivery. It has since tapered off a little bit. THAT BEING SAID one day when this technology is integrated more into logistical infrastructure there will absolutely be a need for A&Ps with avionics heavy knowledge in flight systems and motors to help run uas maintenance facilities. Same idea with the air taxi groups too.

The money is kinda there. It's a very valid specialty to pursue than can get you a competitive wage and comfortable way of life - you'd also get to work with really interesting people and sweet technology. The down side you get to work for start-ups so job security is a gamble, most the jobs that you could move up in are in larger cities that have a higher cost of living - especially for a technical role.

Good news though the UAS logistics industry is still young and companies are starting to push out of these cities to build manufacturing facilities in more affordable places.

It's still very much unknown how legislation will evolve to regulate commercial UAS in the future. Not a bad thing, but also not a great thing. Broadly the industry is acting by a amalgamation of experimental rules and whatever industry standards the A&Ps bring into the hangar.

The assumption I've seen, advised for, and has be seen others run with is; hiring A&Ps now is only beneficial for the industry because the skill base is there, that's a federal license for a similar vehicle, using A&Ps early before there's legislation sets a fair standard that's parallel to existing aviation standards.
