Well Thomas I don't know exactly what I will be forging. I am just getting started. I just want to make sure I don't totally mess it up. Making it adjustable does make the most sense. It shouldn't be hard to do. Thanks guy for your help. I know it probably seems like you were pulling teeth to get answers but sometimes I have a hard time writing what I am thinking. Thanks again.
An 18" tall band of steel that goes all the way around and sets on top of the rivet forge. It needs a hole cut in the side so I can put a piece of steel in the fire to get it hot. The top for it tapers up to an 8 inch opening. I don't know what type you would call it but I hope that describes it.
Right now it is an 18 inch tall band with a top that has an opening for an 8 inch pipe. I need to cut an opening in it but don't want to get it too big. I hope that describes it well enough.
I have a rivet forge I am getting ready to install in my shed. I had a hood made but I need to cut an opening in it. What size should I make the opening so it draws good but has enough room to work? It will be hooked to an 8 inch pipe.
Not to hijack the thread below, but other than $100, what is the difference between a $30 hammer and a $130 hammer? I was looking at buy one but didn't know if I should be cheap or spend the extra money.
