Check YouTube.

Either you're not doing 8k for long enough to gain the edge or you're changing the angle and rolling the edge off.

Try 4k then stropping it

This sounds about right. It's a skill, OP, one that I can't grasp, unfortunately; so stick at it over time.

I guess what I'm trying to figure out is if these things are even capable of advertised pressure. 1T through 3T use 20:1 ratio for gearing. Implies 3T would have 3x the lever length of a 1T... Which is definitely not the case.

we have 2 at work, a big one and a small one (looks like one in pic)

i fucking hate the small one, idk the tonnage rating, but probably 1t and 3t
the bigger one has a longer handle, but like, the whole arbor press is scaled up for the bigger one, so everything is bigger, but i dont think it has 3x longer

I have that thing. Err, had. The shitty circle thing that holds your shit cracked. I used it to push pins into things. Ended up having to use a hammer which defeats it's purpose.

The only way to make a furnace that doesn't use blowers is to take advantage of convection or whatever it's called... heat rising out of your furnace causing fresh air to be pulled in.

I might be stupid and wrong, I'm kinda just pulling this out of my ass lol

The advantage to using blowers is you can seal heat inside your furnace, letting it reach higher temps and be more efficient.

It allows you to program, test, and troubleshoot the motorola 68hc11e20 microcontroller.

This pic is what happens when I try to use the e20 ribbon cable for the e20em variant. It's possible the only difference is the pin out, but I just don't have that kind of luck.

Bump, would an airtight crucible even be possible though?

Yeah I don't even know. am trying to create a super conductor using YBCO with out paying a ton of money

I assume you don't want oxygen fucking with your shit?

Just flush the oxygen out with a gas that's not corrosive but heavier or lighter than oxygen.

That would be much easier, cheaper, and more realistic.

You would basically build either a box open at the top or the bottom, and activate the flush and you'd be fine.

What about baking powder and vinegar lol I can't recall what that makes or if it's heavier or lighter than oxygen.


If you're wanting another benefit like requiring less heat to melt whatever you're melting, I'd imagine that would have to be ridiculously expensive with returns only viable under mass production... even so, solar panels would probably help you even more than the little energy costs you'd get from being able to run hotter with less energy.

Check out this thread - all kinds of people using (food grade) agricultural tanks into conical fermenters. I bought one for about $50 and it works great. http://www.homebrewtalk.com/f51/super-simple-15g-plastic-conical-276378/

I like them but have never made one

>>959801
I made this one in around 10 minutes because i wanted somthing green in my weeb battlestation, wrapped some pebbles in a bit of napkin, did the same for the roots of the plant (just a weed from my yard), stacked them on top of each other in the lid of the mason jar, added a bit of water, and then sealed it up.

>>959797
I've tried doing the light bulb terrariums but it's fallen flat but I've half-assed it
always wanted one though

Loads of inventions were made simultaneously by different people but lack of instant communication kept them from knowing about each other

It's not so much about inventing stuff but marketing it right if you want to be successful and making your product better than any other competitors

>>959679
Patents only last 10 years compared to copyright's 110

You just dont look for an invention. They're found creating something else, something bigger. You'll need a function, a mechanism, some special process which you wont find. Here is your Invention

>>959690
Wrong

>>959374
Might be that the capacitor to the pump motor is shot and you have to get it spinning before it will start on its own. Pull the fucker out and see if it will turn when under no load. If not, and it starts spinning if you help it a bit then its probably a bad cap or centrifugal switch.

>>959449
Thanks i'll give that a try

Is there any damaged seals on the impeller housing? The smallest leak to allow any air admittance will stop the pump from priming itself.

Whittling spoons. Aiming for a kuksa, cant find decent birch tho.. And you probably mean you bought "chisels"

Another pic

Stationary field clutch. Pretty worthless.

Thanks for the answer. At least I knew what it is.

That one you posted, on both counts. The magnet sticks to drywall screws. Find 2-3 screws, draw a line, bam, stud found.

it doesn't tell you anything about the stud itself, just where the screws are, so you'll have to use your brain a bit. But it's only 5 bucks and works better then anything short of thermal imaging, so I'll take it.

Lefty and Righty are your cheapest stud finder when it comes to drywall.

the best and not cheap and the cheap are not the best....don't waste more money on something you're never going to use

or let me refrase. is there something colder than this, which one can buy at a convenient store?

>inb4 L.Nitrogen. i cant get that in my country

Just wrap it in duct tape 24/7.

Or buy a bottle of butane for lighter refilling, it costs a fraction of the price of butane for wart removal.

But seriously, oxygen occlusion therapy works

This might be a stupid advice, but have you thought about just googling "Arduino projects" and looking to see which ones you find interesting and believe would be of good value to do with him? Then just do the project and teach him along the way.

>>958461
The kit came with a book, but Even the first circuit didn't work. I'll Google it, but I want his first project to be a succes.

>>958459
>good with PLCs
>barely do basic programming
does not compute
I mean, if you can handle logic gates why couldn't you handle anything else?

Maybe you should try Verilog and an FPGA instead, it might be more up your alley.

I'm not sure what that site is, but you probably got scammed.

i dont think so, i believe its a database with a lot of different parts and it just does a lot of calculations.

pic related is my upcoming setup, includes GLB 3 axis gimbal but im not sure on the ESC's yet.

i want to do a quadcopter. Nothing big, a simple not to expensive quadcopter. I have 3D printer so i cen design and print frame parts, but i have no idea about electronics. What is good what is not? What goes together, what i need. So is there any good sites or guides for beginners? An open source community like raprap?
