killemall8 Posted October 27, 2023 Report Share Posted October 27, 2023 From an engineering/ scientific standpoint. What will make a stiffer neck? a 1/4" x 1/4" square carbon fiber rod, or the standard 1/8" x3/8" rod? Quote Link to comment Share on other sites More sharing options...
curtisa Posted October 27, 2023 Report Share Posted October 27, 2023 Thin/deep. A square section of any material is more bendy than a rectangular section of the same material if bent along its narrowest edge. Similar reason to making a laminated neck with the laminations stacked side-by-side vs one on top of the other. Quote Link to comment Share on other sites More sharing options...

ADFinlayson Posted November 3, 2023 Report Share Posted November 3, 2023 A taller one is going to be stiffer in that direction so will certainly make a more effective stiffening rod. That being said, 3/8" is quite tall to be sat either side of a truss rod and I'd be concerned about carving a neck that isn't very girthy. the standard size for carbon fibre in UK seams to be 4mm x 7mm which I think definitely does the job.
