What is Pirate 4x4, Ih8Mud, Four Wheeler, 4x4 Offroad, and BangShift?

answer:

organizations that will never feature this FJ40.

I must say I fail to understand this one... since they have featured you in the past.

metal ring is in tough shape



ugh fiberglass



start of fix


I always thought the doors between the 76 up was interchangeable, they're not

Get a bigger coat and some electric socks, then you will not need doors and a top

Bummer on the doors, hard to tell the a post is diffrent?

[SuperBuickGuy]

The post doesn't really matter because I'm cutting it off for the half doors.... still, the conventional wisdom isn't

How often is THAT the case??!!

So the doors will work for you?

yep, I'm cutting the top frame off - but it does change, a bit, what I was planning. I was going to use the upper part so I could have a one-piece window in the hardtop door.... since it doesn't fit.... plans are changing.

Got more done, and tomorrow I need to go get my aluminum tank filled with nitrogen.
first though, etch the bare steel with phosphate


then work on the lay out of the door shortening




interesting, notice how the top offset bend is about the same as the missing bottom? I now know how I'm going to fix it.... which lead me to other tasks (like clearing a bench)
side boxes now formed


and the bench is now free to do the lay out on the doors.

As for the nitrogen - in passing, Filthy suggested checking the pressure of the nitrogen in the shocks. One is 50 psi (didn't even bother checking the other), which it should be 150 psi... so tomorrow I'll go get my tank filled (bonus is I can use it for tire filling)

What's that stuff used for drinks machine? Plastic handles and aluminum tank?
Know a guy who uses it for his wire feed welder and filling tires..
What is Nitrogen used for?

[SuperBuickGuy]

it's the gas in the gas shocks.

DB - About 80% of the atmosphere. The fizzy in pop is CO2, not nitrogen (which is N2). You can use N2 for welding I guess though most use argon or an argon blend. N2 and Argon are inert gasses which I think means that they carry no oxygen so there's no O2 (oxygen) in the weld process.

Thanks Dan and Aaron..

kind of weird, they call welds with impurity in it oxygenated welds... strange, no?

The problem with oxygen is it burns and unless you displace it, it will cause hot spots in the weld (along with allowing the tungsten to overheat because, wait for it, the oxygen burns)... so all those little holes in an oxygenated weld was from combusted oxygen.... cool, no?

and the other half of that question - I'm too lazy so I'll just cut and paste

The heat capacity ratio of nitrogen is almost the same as air (N: 1.404, Air 1.400). So when you compress nitrogen, the temperatur and pressure of N raises even a little bit more than the temperatur of air by the same compression ratio. But that should't surprise you, air contains 78% nitrogen.
If you use compressed air in your shock and there is a leak in your bladder, oil and air will mix together. So at your next landing, your shock will turn in to a diesel combustion engine (if you use a flammable oil)
If you use argon, it will be safe because it's a inert gas and doesn't react with oil. But the heat capacity ratio of argon is higher (1.67), so if you compress the bladder, pressure and temperature will increase more as when you use nitrogen.

and nitrogen molecules are larger than oxygen - thus, it doesn't infuse as well into the oil (nor, if you put it in your tires) does it escape out of the tire as easily)

I need to unload the shocks (either that or get a different regulator) and pressurize them to 150. I equalized the pressure to 150 on the ground and drove it (optimally, it should be 200-250 psi when loaded) - wow what a difference that made.
