I have just looked at Tech413's pics and had a 'duh' moment. Great solution for an airgate. I plan to make one very much like it this weekend. A few weeks ago I purchased a Roger Lorance fire pot. After installing it with a little blower, it worked so well that I now need to put the airgate on. Thanks again for the idea and great pics.
I am also adding to my portable forge some ideas I got while working as a student at Touchstone, a teaching lab for blacksmith's south of Pittsburgh Pa. It's great that so many are willing to share information and ideas.
