Small point, but the flat discs are "rolling coulters" (or just "coulters")
for moldboard plows. They usually have a round center hole and a ring of
mounting holes around that one.
The concave disks are "disk harrow" disks. They usually have a square hole.
It wasn't clear to me if the guy in the first video was going to make one of
those things from a coulter or if he was just showing the coulter to the
customer. (My Spanish isn't very good). Looks like he always welds up the
holes to me.
If you don't find any discs from other sources, check out any used farm
equipment place. They often take old disc harrows apart to prepare them for
scrap.
For example, here's one that's close to me (Downing Tractor):

Farm auctions can also be a good source.
Related to farm auctions--- There are almost always a couple of guys who do
scrapping for a living who come to farm auctions. They buy up the old,
worn out, obsolete machinery that no on else wants to bid on. They take it
to their location and dismantle the stuff to sort it into piles that will
bring the highest scrap prices. (Cast iron vs. sheet metal, vs mild steel,
etc..).
They will most certainly be the guys who will have the discs available. If
I wanted to locate them, I'd contact any farm auction service in your area
and ask for some names.

I am looking for a few (1 to 6) large (1 or 2 36 inch and 1
or 2 26 inch, and 1 or 2 22 inch nominal diameter) used
plough disks. These can have either the smooth or
scalloped/toothed edge.
Should not be too rusty.
Plan is to weld up Argentinean style discos de assado for
some family members. To see what I am talking about goto

Main difference between the Argentine and Mexican style (and
a wok) seems to be that the Argentine style has a 2-4 inch
[5-10 CM] lip welded around the outside to allow these to be
used as a paella pan and for braising in addition to stir
frying.
To see one in use goto
