I build similar truss rods but use round mild steel or sometimes high tensile steel for both pieces - though low grade mild steel does the job well. Truss rods like this are only single acting, but are cheap to make. I also only use brass nuts - not steel. In order to make a two way truss rod, the adjusting rod needs to have a right and a left thread fitted. Just a small point also, you are not welding, you are brazing if you are using phosphor bronze rods and soldering if using silver solder rods with flux. Cheers, good presentation mate!!
Yes sir this is single action. Hard to describe a dual action with words only but the front sleeve would be threaded and the nut welded to the round rod. Instead of being welded solid at the other end there would be a washer welded on either side of the sleeve. you get a push pull action that way if that makes sense. A bit more complicated to make. I've never had a need for a double action rod though some people swear by them. I build the neck with about .005 relief built in before gluing on the fret board so the tendency is for the neck to bow forward. Never had a neck back bow although I understand it could happen. I think the built in relief prevents that in my experience.
Another great informative video.👍
Thanks 👍

Point well taken! Thanks for watching.
🎉 very cool
Thanks
So, this is a single action truss rod? What would be the assembly difference with a dual- action truss rod?
