Lunar240z Posted March 31, 2007 Share Posted March 31, 2007 I'm planning on making a catch can, coolant overflow tank, and EFI surge tank from some sheet aluminum i have. I've got a lot of .063", and a bit of .125" sheet. In your opinion would the .063 be an adequate thickness for all of these items? i was wondering mostly for the surge tank, because i believe my fuel cell is made from .125" . The surge tank is before the high pressure efi pump though...I'm pretty sure the .063'' will be okay for the catch can , and coolant overflow...because they're made from plastic sometimes... thanks.

evildky Posted April 1, 2007 Share Posted April 1, 2007 some of my favorite catshcans were fabbed using old aluminum a/c reciever dryers, I keep saving them planning on doing this but my aluminum welding askills are not there yet Quote Link to comment Share on other sites More sharing options...
260DET Posted April 2, 2007 Share Posted April 2, 2007 My last surge tank was made from a piece of al tube, capped both ends. 2-3mm thick. Quote Link to comment Share on other sites More sharing options...

Oh wait... it was. Quote Link to comment Share on other sites More sharing options...
johnc Posted April 9, 2007 Share Posted April 9, 2007 .063" is plenty thick. Quote Link to comment Share on other sites More sharing options...
Roostmonkey Posted April 9, 2007 Share Posted April 9, 2007 Unless your a decent welder, welding aluminum thinner than .063 can be a nightmare.Weight isnt a factor with that amount of material so I'd say use the .063 stock. Quote Link to comment Share on other sites More sharing options...
heavy85 Posted April 15, 2007 Share Posted April 15, 2007 For catch can and overflow it doesn't matter. Hell people have successfully used plastic Coke (substitute beverage of choice) bottles for overflow tanks. However I personally would be conservative with the surge tank due to the nature that it holds highly flammable liquid and last thing I would want to see is stress a crack (from welding or vibration or the way it's mounted or poor penetration or etc) ... but then again fire scares me. I'm am dumbfounded how people wear sleeveless shirt and jeans at the demo derby when at the two I've been to about every other run is temporarily stopped to put our random fires. Seems to really depend on your welding skills to me. Cameron Quote Link to comment Share on other sites More sharing options...

CRAVED Posted May 24, 2007 Share Posted May 24, 2007 looks like a good start, is there baffling in it or is the long side a horizontal line? ie does it sit how it is in the pics? or will it stand up? Quote Link to comment Share on other sites More sharing options...
Lunar240z Posted May 25, 2007 Author Share Posted May 25, 2007 it will sit long ways, the bottom is angled down towards the back Quote Link to comment Share on other sites More sharing options...
