Here's the second iteration of this spiral torque motif . I tried a slightly new technique that is giving me favorable results allowing me to control the deformations and collapsing as I twist the bar with one hand and torch heating with the other.The key is to PULL TENSION as you twist.This lays up the ridges more evenly... It's still quite a chore to try and keep the seams from opening up when I wrap it around the neck form for the final heat but it does seem to be an improvement.What I find most curious and surprising is the amount of material that is taken up in the twisting.I started with a 24" bar and it's been reduced to 16" overall.
This is a lovely Torque. So this starts life as a flat bar I take it? Did it start out tapered or you pulled and stretched it to get it narrower at the ends? The twist looks really good and the shape is really nice. Looks good on too.
Yes it starts out as flat sheet that is cut to taper both ends 24" long.Because of the twisting it consumes allot of material.24" down to 16" finished length.
