We are gonna builld a usefull size, fuel efficient forge, that is small enough to take along with you to where you need it. We are gonna do this with the junk I can scrounge from my stash of junk. This puppy will get the steel hot enough to forge weld.
Ok, this is the victim, an old air tank that dont hold air anymore. 'Round here, there are one or two of these in 'bout every garage, carport, and toolshed. Brand new they are like $24 from Harbor Freight.
First we mark for the cut. I had a chunk of steel exactly 6 inches high, so I set it beside it and marked along the sides, and the ends...
This is the dangerous part, cutting out the line. I'm using a cutoff blade on my angle grinder. you can use a jigsaw, cutting torch, anithing that will cut it will do. If you are using the tool that I am, keep in mind that you dont want to plunge too deep... just enough to cut through. if you get the thin disk bound up, BAD things happen!
I'm gonna assume you do not have a welder. I normally, after making the cut down the first side, weld the hinges on, then continue the cut. I'm gonna do this the hard way, just for y'all, with nuts and bolts. Continue the cut on around till you get the top off.
Use your file, sandpaper, or flap disc to dress the edges... them's YOUR fingers after all...
Almost everyone has a set of door hinges stashed somewhere in a junk drawer
Now put the top back on and trace where they go with your Sharpie
Drill the holes for the hinge bolts.
Now set the bottom half on end.
Make several cuts (like an asterisk) centered 2 inches up from the bottom.
Use a hammer to drive the wedges in.
Drive in Your air pipe. I chose 1 1/2 in black iron pipe.
Here's the hole
Now do the same thing for the other end.
The pipe should slide all the way through.
You want to be able to open both ends so that you can remove the ash that builds up in it. Most people use a screw on cap and a threaded pipe, I just made a slip in plug from another piece of pipe that already had an end on it.
Decide which end is gonna be the front, and make two cuts like so... using your high tech bending tool, bend the piece down to make a shelf
Clean up your edges..
You should now have something that resembles this
Now drill a line of holes down the center of the pipe
More tomorrow!
