I've built a Reil-style propane burner for my first forge. I haven't purchased a regulator, etc. yet, so it's pretty much just the burner and the propane tank (the type you trade in at the grocery store for your grill). Does anyone have any experience with this type of project that they could share with me, besides the obvious "Don't blow yerself up"? Particularly, I'd like to know about how long a tank of propane should last and what kind of high pressure propane regulator is best to use on a budget. As this is my first project of this type, any information would be helpful. Thanks!
