My brother in laws dad ( no longer with us) made gigs forged from leaf springs
I looked at Admiral Steel -http://www.admiralsteel.com/products/blades.html
5160 is what most springs are ,the widest I found was 4 in. & $$$
You say you wanted to cut them out not forge.Just thinking can you weld?
Or have some one Weld it for you? Like make 2 -1/2s out of 2 in and weld them to each other.
My Grand Dad ( Moms Dad) had to gig in the winter to help feed the family.
Mom tells- Everyone in town wanted to go with Tom giging ,he allways brought home tubs full of fish. I guess he was really good.
He passed before I was born and from what Mom has told me he made his gigs
only info she knew about his gigs they were as big as his hand.
Not much help
I dont think forging would be that hard to do
I would think its like making a Fork -I think there is a BP on forks
