Yes, it's perfectly legal to videotape or photograph anyone in public space BUT isn't legal to publish it without the permition of the person involved, otherwise you have to protect the identity of that person.

About 3.
In Argentina there are only a fewtalented /diy/erin homeschooling. Mostly in rural communities have rural school. Those school are like homes for that children, but isn't homeschooling.
Most kids walk more than 5 miles to go to school. It's really depressing watch thosetalented /diy/er because their're really poor and the schools that they have are small and doesn't have many resources than the teachers.

I study aerospace engineering, and i desing bicycle parts (design and quality control)

ah, ok. i was searching the isothermal conversion diagram to look that. because i have the doubt if is martensite or austenite.
i probably gonna do a very bad job tempering the metal so is not critical.
thanks

>>417346
Thanks, i will give a try.
Looks better than pvc.

No, english isn't my native language.
Temper i mean when you heath the steel over 900ºc to form austenite, and then control the cooling proces to obtain an especific iron estructure (ferrite, etc..)
>>417303
I guess that the word "templado" in spanish means "quenching" in english. And "revenido" means "temper", maybe i confuse with that word.
The steel is SAE1070.

No, worst than Canada. in the fucking 3rd word.

>>416927
hahahah, ok.

>>416567
it was annealed before cutting and grinding. After i finish the blade and the holes for rivet i will temper it.
About g-10, isn't hard to make, but i'm too lazy to do it. I can't buy it, because i live in a "socialist" country that forbbiden people to buy what they want, we can only buy what goverment's friend sell.

>>416447
No, it's just what i have in that moment. I didn't have much to choose.
By the way, i too lazy to start my furnace yet. Maybe next winter.

other pics from my knife

Hi /diy/, this is the knife i'm making. It's very small (just 17cm-6.7in) because i want to carry it in my pocket, or not so visible.
I can't decide if make a grip of G-10 (homemade too, because i can't buy it here) or make it of wood.
Also i will need a Sheath, i want a kydex one, but i can't find it neither, there is some other plastic similar? maybe pvc?

>>410812
thank, i will look if i can download o buy it as ebook.
i want to make forjed knifes. I only make one in my life, and wasn't very good.

>>406877
what book is this? where i can download it?

Give it to me!! hahah
Make a briefcase. it's kind of cool and light weight and strong. And a few people have it.

isn't that. For example, if you have a cube 10cmX10cmX10cm, how many liters do you have?
or do it backwards, Tell me the other size of the cube if one size is 20cm and the other 10cm.

There you go.

The metric sistem allows people to be more accurate. it's not "about" "close to".
It's easyer, everithing is divisible by 10
1km = 1000m
1m = 1000mm
1lt = 1000mL
And so.

>>324530
it's easyer and quicker with metric sistem. When you want, for example, turn in a lathe an spindle, and that spindle comes with a bearing bead. The bearing bead is easyer to measure in the metric sistem, if is 22mm (almost 7/8) but 7/8 is 22.22mm, and 0,22mm is to much diference and the bearing will not fit.
Even the imperial sistems recognize that is to hard to turn in a lathe with fractions. So they convert the inch to decimal, and you hace 0.750 inch, 0.5 inch, etc.

"heavy", a "heavy lathe weights like 500kg.
Make another tools for your lathe, like morse cones, and so.
Build flashlights, kubotans, a hammer,
