Thank you gents. Yes the chain was fun for sure. What I ended up doing was clamping a str8 edge to my welding table, then laying out the chain along the edge with the opposite link resting on the str8 edge with the opposing link running along the side of the str8 edge then with vise grips locking it down str8 and tight. After that I welded each link to the next one, two welds rack on the back of the chain only to keep it clean. Worked well.
Heres a couple of close ups Kevin O so you can see better. I hit rivited it together and welded in the spacer/ catch at the top.
Aus, heat paint is just 1500 BBQ grill paint.
