Making a puke tank and a swirl pot.

I got a car on the road a while ago, and now I'm working on getting the new car bugs out.

This car is Off Topic for the HAMB ( look for it on the Dogfight Forum ), but this Tech is usable for Trad Hot Rods as well.

It had cooling problems. ( overheating)

Part of that was probably a timing issue, but that is solved now.

And I figured Id make a couple of improvements to the cooling system, just to make sure.

I started by cutting a couple of discs out of heavy gauge sheetmetal, and annealing them.



I made some discs out of 3/4" plywood for a hammerform, and I hammered the edge of the discs over.





These are the endcaps on a piece of 3.5" exhaust tubing.

 

I brazed on a couple of tubes.

The one that connects to a tube coming from the radiator goes in the top of the puke tank, but goes all the way to the bottom.
With just a bit of clearance to the bottom end cap.

Its brazed to the side, so it cant vibrate loose.

The overflow is almost flush with the inside of the top endcap, but it goes to the bottom of the tank as well.
On the outside of the tank, its also brazed to the side incase of vibration.

Then there are two short 180 deg bent pieces, on the top and bottom endcaps.

They are inline, because they will be connected with a piece of clear tubing later.
This is so I can see what the fluid level inside the puke tank is.

 

Pics didnt post..

 

Second rd of pics not showing up

 

Should be visable now...

 

Never mind. Showing now. Interesting.

 

Looks like a pipe bomb.

 

The swirlpot was made pretty much the same way.

The idea is to get the coolant to swirl inside this pot, to get all the air out.

Thats why the tubes are welded in off center.

It has a pedcock on the top, in the middle.

And it is the highest point of the cooling system, when its mounted on the car.

Its fitted between the thermostat and the radiator, connecting two pieces of the top hose.

 

To make a ridge on the end of the tube, I bent a piece of welding rod.



And I brazed that to the end of the tube.



This way the hose cant slip off when the pressure builds.

 

Here they are mounted in the car...

 

Thanks, there on my to do list.

 

Nice project.
But.....
I really like that even the tech editor as trouble with the pics.

 

Haha... Yeah, it happens...

 

What exactly does this do and how does it help. You lost me.

 

Water is heavier than air.

So when you spin it around the water and air will seperate.

If you then give the air a place where it can escape, you can get rid off it.


Tried and true Road Race tech...

 

But the oval track guys don't bother.

 

Very nice job!!
