So about to make my manifold for these burners. For natural gas did you use any type of regulator (short of a valve to adjust flame) ?

And same question for propane - If I kept these as is - Don't I need a regulator between line and tank?

Natural gas is regulated coming into your home, so you just need to figure out how much to drill out the orifice. Make sure your manifold is at LEAST 1/2"
Propane is high pressure and needs to be regulated from the tank.
If you look am my profile I have a Pic. of my stand and how I ran lines.

Here's a pic that shows the hole size difference between high pressure LP (left) and NG/low pressure (right)-

FWIW, 1/8" is kind of an average, and depending on your exact gas pressure you may find that you need a slightly different size orifice for optimal performance. Start small and work your way up, since it's much easier to enlarge the hole than it is to shrink it. I started with a wire size 35 drill bit, and ended up working my way up to a size 29, which is a couple steps larger than 1/8".

Also, depending on where you live the shipped price from agrisupply may not be the best. They have pretty high shipping charges to the west coast, and total shipped price here in AZ was actually cheaper through Amazon.
If 1/8'' is average, any idea what the commercial one on the right is?
