I've done lots of copper pipes for my flamethrower and they held up to pressure just fine. I used a propane torch and regular pipe solder/flux from a hardware store.

Now I want to make a HD block from Cu like Blade did. Can I just stick the top and bottom together, flux it then use plumbing solder?

As WRT Copper stock, its fairly expensive from online metals and I don't know of a local place. My plan was to get a bar of 4inch by 3/8 inch Cu, cut most of the center of one piece out, then solder the other two pieces together as the top and bottom. Will I be able to put 1/2inch barbs on it? They'd need to cross the solder lines. Is that OK?
