Hello Everyone, new to the board

[Jim McDougall]

Hi Pbinns,
While I am presently away from resources I would be glad to look into these things shortly. In the meantime I would confess that my knowledge of the metallurgy of these swords is very limited and I would defer on that topic to Lee Jones, who has done considerable work on such study of these swords and written some outstanding material. There are also a number of extremely qualified members who often address metallurgical topics whom I hope will respond.Possibly using search on this site will reveal answers to many of your questions, and hopefully further discussion here will help us all learn more on this fascinating topic. I hope you will keep us posted on progress OK?
All the best,
Jim

Also your thoughts on the steels and techniques used to make the later Ingelrii type swords would be greatly appreciated, I am thinking of chiseling in the inscription then hammer welding in the small PW twisted rods into the billet, then repeating for the reverse patterns. The fuller is then forged in after. Again, the problem I am thinking is in the actual blade material. Would it be better to make a wrought iron and steel sandwich , or keep with an all steel blade, strongly etched to try to get some grain out of it ?

Definitely steel blade, but don't etch it - I bet the originals were polished and the inlay shows up via the different polishing effects on the two or three steels/iron involved. But you can't buff it on a motorized wheel, got to be hand polished.
Are you familiar with Jaap Ypey's articles, he x-rayed many blades during conservation, did very nice drawings of the pattern welding. Also did some metallographic analysis, found on one blade a difference in carbon, but not phosphorus if I recall.
Welcome, and may all your welds weld well
