Welcome to the forum !! 
Nice how-to right out of the gate. I:I Model # of your welder? I really want to get a decent 220V gas mig, welds are sooo nice. All I have right now is a Tombstone and a little 90a wire welder that's not good for much but tacking and real light stuff. Little green for ya too !! I:I

Its just a licoln 180 from lowes. they had a big sale plus with my military discount i picked it up for like 450 or 500 can remember. she will get pretty damn hot i usually dont do anythig over a quarter inch but on my rock crawler i have done half inch plate with it.
I didnt put any flat bar in it. the inner tubeing goes 3 in in each side of the old swing arm plus the way im wraping it to clean everything up will provide strength also.
Ok so I got to work on it for a few min today. One thing you should do different than I did is center the inside tubing that is for support ill get into why during this portion of the walk through. So my not so par steel company here didn't have the outside tubing I needed either, so I had to improvise. The stock swing arm is inch and a quarter by 2 inch. Closest thing I could find was inch and a half by 3 inch. Here's what I did chopped A 6 inch piece, and then cut one inch out of the middle.

This step is where it would look cleaner and take less blending if the inside tube was centered I had a pretty good buzz before I started yesterday and didnt think about the wall thickness of the wrap Im putting on it. With that being said it may be a tad higher on the top side of the extension nothing that cant be ground down. Pretty much just tack weld it once you line everything up.
Another view of the tacked portion. I trimmed a small portion off the end of all of these portion so there would be a small gap that i can fill. it will allow a smooth transition when I blend everything, as well as help with strength. This way the wrap pieces will be attached to both the center tube and the original swingarm.
Now tack the bottom portion of the wrap. Just lay a level across the gap to get the right height for the wrap and tack away.
Ok just do the same with the bottom as the top with the smaller piece that has the quarter inch trimmed off of.
Now just fill in all the welds. I made thick weld that sat a little higher than my usual welds. I only did this for blending purposes I wanted to be able to grind them down with out any areas being to low when I start blending. This pic is kinda sh*tty but you should see what Im saying.
Now just grind away till you get it to where you want. I started for a minute but didnt get to finish. Im gonna wake up before the baby and wife tomorrow and finish this part up. You guys start thinking of some cool sh*t to do a walk through on. Im thinking making it where I can use a round carrier thats what i did on my R6 Raptor.
