Alright so just got back from metal supermarket.
I have the steel so we can start building the weldments to lift the Delorean.
Alright so the exoskeleton is pretty much done, and ready for the expo.
So I just wanna go over a quick overview of the system, and how it works.
So you notice on the back there are two power switches
there is 12 volt power switch and 24 volt power switch.
12 volt turns on the fans ...
and powers the solenoid valves.
The 24 volts switch powers the compressor.
Once the compressor reaches the maximum pressure of 200 psi in the tank.
Another solenoid valve will actually shut off the compressor and it will be silent again.
So we have a pressure regulator on the left right here and this is because light cylinders aren't actually rated for full 200 psi.
We have to limit the pressure to 150 psi
We have lots of extra ports for additional accessories and more pneumatic's in the future.
and over here with have our pressure gauge and this brass valve here is actually a pressure relieve value.
So basically if the pressure in the tank exceeds I believe 220 psi there's a spring in here that releases and all the air will be evacuated from the cylinder.
Alright now on the front
we have our tackle vest
we have an arc reactor just for show
and the main control right now is just by 2 switches on either glove
So if we turn on the 12 volt power
You can hear the solenoid valve go. So this is the release valve.
So this will allow me to release the load of car and lower down.
The other glove
is the one that fills the cylinders allowing me to pick up the car.
Alright so its time for a little bit of knee surgery the problem is that the knees don't lock
and so they can buckle backwards.
But
By welding this piece on here.
They can lock.
Alright time to do a dry test I'm gonna lift my car.
Its a bit lighter than a Delorean but we'll see how it goes.
Alright so our weldment is bending a bit more than we expected its not quite the deflection we were expecting
we did run an (FEA) analysis on a computer, so we may have to bulk this up a bit before we pickup the Delorean.
But were going to the expo uh in 2 days and some of the metal places aren't open on the weekend,
so were gonna have to figure something out. cause as you can see its not lifting the car up that much
because the steel is bending so much.
On the plus side it does mean the exo is working as planned.
Now I'm just gonna go ahead and bring it back down.
So we tried to fix that by adding a second piece of 2 by 2 and that still wasn't enough.
When we tried picking up the truck the cylinders went up but we actually ended up bending the entire beam.
Which was kinda concerning.
Luckily our neighbor had some more steel, some steel bar that just happens to fit inside the 2 inch tube.
So what we are gonna do is put 1 of these on each side use a sledge hammer to smash it in,
and then hopefully it'll be strong enough then to pick up the Delorean.
In addition to adding those steel beams inside were also going to add another steel weldment right here in the middle.
to really help beef up the entire structure and hopefully that'l take care of our bending problem.
[background] Good?
YEAH!
[background] Alright bring it back down.
