More Adventures From The Backyard Workshop

So who doesn't like swords?

The shorter of the two is double edged and made from 2" x 1/4" 4140 cold drawn carbon steel flat bar. the

The guard is made from a piece of 316L stainless steel 2" schedule 40 seamless pipe. This was cut in half longitudinally. There is a piece of 1/4" cold drawn carbon steel square bar welded into the bottom with 309 stainless filler wire.

This allowed the previously shaped and sharpened blade to be full penetration welded to the square bar using high strength E80S-B2 vanadium steel filler wire. Short intermittent sequence welds we're used and allowed to cool thoroughly before the next sequence was applied. This sequencing prevented the blade material from heating up to the point where the temper would have been lost.

The Handle is made of two pieces. The main portion is made from 1" cold drawn 12L14 carbon steel hexagonal bar. The pommel is 1-1/4" 420 stainless steel round bar. These two were welded with 309 stainless steel filler wire. This assembly was then carefully tacked and welded to the to the outer side of the pipe section in order to maintain axial alignment with the blade.

The balance point is about 1-1/4" from the base of the blade so it can wielded with either one or two hands.

The longer blade is single edged and again made from cold drawn 4140 cold drawn carbon steel. This time 1" x 3/8" flat bar was used. The guard is made from four separate pieces of 1018 cold drawn 1" x 1/4" flat bar. The edge joints were deeply v-grooved, corner and lap joints were full fillet welded. The blade was then full penetration welded to the guard with the same method as above. The handle is made from 13/16" 4140 cold drawn round bar and 1" 420 stainless steel round bar.

Still yet to be made are display boards for hanging them on the wall. These were made for display but the 4140 quenched and tempered takes a wicked sharp edge!
