When I was out in Tx a while at at T1... came across a little gadget in depths of the shop... what a great idea... lol.


works like a charm.

 

Cool so like 4x4 aluminum box tubing to suck the heat out of whatever you're welding? That's a cheap way to do it and definitely effective, I went the expensive route and use 1'' thick aluminum plates, but there's no better way around it, especially for production!

 

i have had no bad experiences. I dont see it 'sucking' any more heat from the weld compared to not having any brace at all though.

 

You could pretty easily water cool the back of that tube as well.... :D

 

We usually bolt it to a junk head but Ive found with things like the Porsche stuff junk heads arent so cheap. Big chunks of aluminum FTW

 

I went even cheaper, 6 x 5/8" hot rolled steel bar and I milled one side to make it perfectly flat.

 

pfft. i bolt it down to a piece of wood soaked in gasoline

Metal transfers heat WAY more effectively compaired to air. A simple test: put one finger ON your car's hot header and another 1/16" away from it - and it won't be the later that burns first.

But when you're talking mild steel and stainless, they are 51 & 15 W/m vs 373 W/m when it comes to conducting heat, so it has to travel through the flange before the alum sinks the heat.

 

I bet if you were to weld caps on both ends of that then drill a small hole in the top you could fill it with water and it would work even better. Someone mentioned that above too

Make sure you dont seal that off....you'd be making a bomb...dumb idea.

 

plus one, i dont see it working out either.

 

you guys trying to kill me??!! lol

 

fill it full of gasoline and weld both ends. and the weld up the manifold

 

nice garden hose in, little 1.8in npt barb with a hose out. turn on your garden hose.

maybe you can hook it up inline with a pump and an ice bath.....

how about a liquid nitrogen container.....

 

yup, we use a similiar setup except it isnt aluminum. im planning on bolting my flange to a spare head where i practice my port and polish work on

It certainly wouldn't be a bomb if you have an opening to fill it with water. It would just evaporate off as steam as it heated up. But yea you could hook up a pump or a hose or w/e too and it would be more effective. I was just thinking simple.

 

that'a great idea. The water cooling would be super simple too.
