Here are some more pieces that will get welded on. Those are 5/16" body bolts along with a 1 1/4" diameter bearing. This should all make more sense when you see it later.
 

I fastened the chain to the tubing with wire so it wouldn't move. Whatever works you know. I welded every other link to the tubing.
 

What I need now is a nose for our little buddy but I didn't have any luck finding one. I want to use a small 'connecting rod', the kind you would find in an internal combustion engine that burns gasoline. I looked online and found the perfect size but it was made out of aluminum. And I want it to be made out of steel because I can't weld aluminum to steel. I also emailed a company that sold small engine parts and asked them what material his connecting rods were made out of. They never got back to me so now what? Looks like I'll be making one.

What I need to do is make some room for this new piece so I'll need to cut the tubing and chain where the arrow is pointing. That way the nose will be centered a little better and should look right.
 

I made a sketch of what I'm going to make below. Just n case you don't know what it is, I'm making a 'connecting rod'. Yeah I know.... it looks like a kid drew it :-]    See that piece of steel on the paper, this is what I'll be using to extract the connecting rod out of. All I have to do now is remove it from that chunk of metal (machinist humor).

What I'm doing next is putting in four holes using a 7/16" drill (to rough with) and then a 1/2" end mill to finish with. These four holes are going to be tangent points that will blend into an angle along with another radius. Hang in there, it will make sense soon enough.
