do you recommend schedule 10 or schedule 40 for the stainless elbows? Im not sure of the difference

 

I just use a CO2 fire extinguisher on my MIG welder, semi cheap bottle and any fire station will fill it up. It has a bottom pipe so you gotta turn it upside down so you don't draw liquid CO2 through the regulator.

 

Can some one repost the pictures of the homemade manifolds they arent showing up!

 

good luck on that man, those pics were posted over a year and a half ago.. look at the twin turbo thread at the top for some nice pics.
