It's a matter of TRUSS!!!
Sorry Steve. I'm no expert in this at all. There is some angle on the neck but I'm not sure that it is as much as it seems in your video. I would expect that the wee barrel nut on the end of your truss rod should be straight went it is not tightened. 🤷🏻♂️

Thanks for the reply..as you can see from the video I'm inclined to agree!!
I haven't built an acoustic yet, so can't comment on the angle. I do rembemer watching a video of Mark making that type of truss rod. I'm not sure, but maybe the bottom rod should be welded the block at the adjustment end so that it can't tilt. It might be worth while finding that video to check that out. I'll have a search for it too.
Its a good question and you’re certainly not going mad. Check twice cut once should be amended to say check twice glue once also. It does seem to me like the threaded part of the rod has a bend which looks too big. I’ve built acoustics with truss rods but not 6 string acoustic and using the old style where the adjusting rod is at the headstock, so I think I will leave the definitive answer to Mark.
Some people call me a tool, others are less complimentary. Tools being useful things.
This should be a link to the video, I was wrong, that bit (refered to as the truss rod thing) isn't welded. At about 5 mins in, Mark is tightening the nut, I cant see anything to stop it doing what yours is doing. All I can think of is that maybe the stubb of yours is a little bit too long and allowing too much play. Sorry Steve, but I've been no help whatsoever. Hopefully Mark will get back to you with proper advice.
Really appreciate your replies and your research robin...
Once again I'm reaching out to Mark, I've also emailed him...so fingers crossed...
I'm slightly inlcined to go ahead and glue the head and tail blocks and but the sides on...as ling as I dont glue the back I can check any truss rod easily when I fit the neck...my big concern is not being able to see exactly whats going on before I close the box completely...
Thanks to everyone for chipping in - good Q!...Short answer - It's OK. 😌
Some things to consider:
- The Aluminium part does look like it could sit squarer...make sure the round bar is fully in the hole - you might need to tap it home with a hammer.
- When installed in the neck the aluminium part should but against the end of the neck which will also help...
- I highly recommend that you get a Ball End Allen Key - that should also help.
- The truth is that it can be a bit tricky getting the Allen Key into the Nut - it is the major downside of this method of construction but nothing is perfect. If you put the adjuster at the headstock end then it weakens the headstock so I prefer this way and think it is easier -especiallyy for the newbies.
- The Truss rod will not bend nearly as much once installed.
- When adjusting the truss rod in the finished guitar you don't even need to put the allen key through the hole - sometimes it is easier go over the brace instead of through it so you also have that option.
It is good to be cautious but in this case you don't need to worry. 😎
Measure twice, cut once...
Thanks so much for the reply, really appreciate it and so good to hear from you...
I'll crack on, BTW, if I didnt mention it before the acoustic course is so good...so clear...
hope to catch up properly v soon
Don't go tightening the truss rod it after you glue the fillet or it will bend and break the fillet!
Also - when the fretboard is glued on the neck will be far too stiff for the truss rod to work, so continue to refrain from testing it until AFTER the neck is carved - then it should work as intended.
Thanks for keeping us all entertained !

Mark made it and you'll see from his reply that doesnt think it will be an issue...so......
appreciate your feedback
