Greetings,

with this philosophy we would stop any kind of developing.

Without getting difficult, are you kiting with a recycled kite ?
Your car is powered by a mule ?
Instead of a smartphone you use what ?

I can go on like this for hours without getting funny

You should be happy that someone is investing time and money to prevent you from riding relabeled industrial junk in the near future

Sorry I am not with you in this case.

tks

Kosta

My kids and I have been sick for a month. It has been a super productive month in the shop.

I don't care how people advance this craft. I like computers and programming. I am trying to encourage more to try by sharing all my secrets and tips.

Oooo the lathe! Great memories with my grandfather, what a fun tool.

My 12 yr old helped me layup this blueish stab in the picture , it went just ok

I remade a refined mold of my standby rear stab, I also enlarged that stab to make a better one for my larger wings. It looks great, I'll mold it today.
Funny, all the rear wings I have toiled over and this completely handshaped reworked one has been the best by far for years!

I'm working on a simple more versatile mast mold too. I'm considering raking the mast rearward 5°or so instead of moving my box back and tapping the tuttle for footstrap.
I may proceed with these white cormorant ish wings , they look cool to me.

My eye for profiles and handshaping has improved, I just hope I'm scrutinizing the right things

Within 5 years you will be able to 3d print a carbon composite wing and screw it onto your fuselage and use it for a long time. It will be accessible to many.
Within 2 years it will be possible, but cost prohibitive.
Check out what MarkedForged is doing. They are soon there.

Those look interesting. I'd like to hear how they do when they see water.

P.S. Hope you guys are feeling better.

Wow! Not a comment, addition or anything, I'm pouring my guts out, for years, every hard won tip that I can share.. I always hope I reach at least one interested builder.
I would love to have the time to build my own wings and it is interesting to learn how others fab up test designs.

In terms of build approach, I would purchase metal molds CNC'ed from solidwoks, and use carbon fiber layup/compression techniques. Molds are pretty inexpensive but take a few weeks. As an alternative, CNC'ing a piece of G10 would be a quick way of validating a design before building molds.
To you have a cnc mill you can use for free? Milling molds from metal is very expensive if you have to pay for milling time. Its definately out of the reals of reality for most home builders who dont have a full fab workshop at their disposal!
I have two friends who have CNC machines, but the cheapest route is via China. Send a solid works file and they send back molds.

I'm on this forum 5 years, the printers did not move much in consumables arena. Tom, I have access to the 3D metal printer...$250 1 kg wire.

~~~~~~

If you don't believe me that we should tax making 3D plastic (which will end in the landfill anyway, together with the printers), STOP for a sec and think why is Government taxing us for Solar panel electricity on our roof? Or a bore on our land? The list goes on. I can't even collect wood in the woods, because it is illegal and heavily fined.

We do not really know what the future will be, right? What are the consequences of having kids with 'welded' devices on their hands? Do you know? Anyone? How about we teach them how to model clay with hands, or carve linoleum with a chisel? Ah, but that's not needed in today's economy.

Teaching 'kids' about the resource management would work if, and only if, we take them to the landfill to see in first hand. Somehow that is not happening, me thinks.

Somehow, we are paying more and more for the kites and boards (or anything). The paradigm that the technology is enabling us to save (money and time), is just a dream. If fact, the tech is enabling us to do more, but understand less (yep, we outsourced thinking to someone else who made a software for us to use). Plus, we have less and less time on our hands. True or false (all of it)?

I could not care less if the kite is cut with a CNC if I'm paying $2000 for it. Remember, the bars are going for 600Euros in the EU! Ridiculous. That will not enable you to do 1080 trick (which I started nailing). The board I still use is a $50 DIY, and laughing seeing any carbon board...1000-1500Euros for the composite carbon board? It won't make you better kiter.

Have a look at: viewtopic.php?f=1&t=2398698

Would he be a better kiter with today's technologically advanced gear? Hardly believe so. The enviro impact was heaps less back than as well, since wasn't that massively produced. We can't just say the technology is more 'green' when we are producing so much more. And that is a problem.


@Kosta

- nope, a brolly ;)

Your car is powered by a mule ?
- using roller blades ;)

Instead of a smartphone you use what ?
- pigeons, they quite tasty too ;)

O DU, true true true

Since I am the father af two lovely kids, I try to repress most of my cynical sentiments. I am truly alarmed about our exploding rate of consumption . The complete disconnect and lack of awareness and concern in the US especially, is horrifying . I did have children though!?

Well anyway, since my second post on 2/5 I came up with an easy dirty molding method. I have now improved the parting edge a bit.

Here are 7 new American made fiberglass molds. Making the prototype wings is still the hard part.
I'm excited to try building the 1300cm2, it needs filler, I'm going to try expanding foam or wadded carbon fiber tow!

Brrrrrrrr


Happy building people!

Is that just the angle of the photo or are those thicker than your first ones?
