Well...Dwelling on all this info from this morning while making fuel,it all started coming back to me...Lars Enander,in his book,had a diagram of that very constr. scheme...
Moreover,by digging through piles of junk iron i even found my attempt of some years ago to follow that schematic...
(it failed in welding,why-no one will ever know,using junk steel is handy that way....

In that photo it is with it's attendant drift,that i also have;so together they make a handy beginning for orienting myself.
Having straightened that old pre-form i find a likely stock,3/8" thick,that i think will forge out wide enough(running ahead,in the end it turned out to Not be enough...
...but will still serve as experiment).

Stock cut to size and "butchered" as per transitions...

At the end of the process as i already said a disappointment,there wasn't enough mass there afterall...(new stock overlaid on old pattern-https://imgur.com/a/piXCtoF;quite a bit shy....).
Now it comes back to me that Lars called for using 1/2" plate...
The pre-form is already under 3/16" in thickness,i'm unwilling to go under that,it's an axe afterall...Will try this as is,and if the volume of space inside the eye will end up being too little,well be it.Firstly,many an old Piilu (and related tools)had almost no opening to speak of at top end;and secondly must keep in mind that i'm not after any finished object,but only want to practice this specific weld.(it still rankles).
For the blade-portion of this i cut off a 2"+ section of 1/2" thick plate,hoping to compensate for the volume inside the eye.
The future tenon forged roughly...

...and here it's offered up to the drift(that i'm in the process of grinding down smooth and reshaping,as it was a disgrace..

Now,after finishing the drift,and making the steel bit for the edge,i'm too tired to even think...It's been over 7 hours at the forge(including making fuel),beginning to get dark outside,all chores still undone...
Tomorrow will be the Welding day...
