Divide the number with 2 to get the axis position on the board ≅1-1,5mm and multiply with 2 to get axis position on the puck template.Īnyway, depending on the fretboard height and radius you need to measure and adjust the axis positioning for both templates as the board on every neck work (if they’re not having the same spec of course). Subtract the radius difference from the fretboard edge ≅2,8-3mm. Example if you are using a 4mm fretboard… The axis on the puck template is 2mm(200%), that represents 1mm on the board. I used 2mm as axis reference on the “Neck Shape Templates for Router Jigs”. Preferably it should be at the same height where the 1st fret neck edges are. Because that will be different each time depending on what fretboard height as what radius you have. It doesn’t represent the center where the fretboard meets the neck wood as I say in the previous comment. (it was a little bit sloppy answer from me) 😉 Sorry! I need to correct myself regarding the axis location Good luck and happy building! BR/ Michael Using bigger sizes will probably make the spring tension harder to operate with as you need longer router bits. Using smaller sizes will make every router movements more sensitive. Regarding the puck sizes: Yes matters! I found that 200% enlargement worked best with router distance etc. 😉 It’s doable… but I’m too lazy for that (for now). I’ll guess if you want to be more exact, you have to go into deeper mathematical exercises. It depends on the distance between the puck & the cuts as how much the puck is enlarged in percent. So it’s kind of relative in how exactly it replicates. Regarding the location: The puck profiles are based on the 1st & 13th fret. The measurements on the axis are 8 mm from the bottom of the board and it’s the same on the puck. The axis location represents the center where the fretboard meets the neck wood. Hi Christian! Thanks for the notice! Realize that I have missed specifying that one. Cheers!Īnd here’s the jig in action: Neck Shape Jig video Hope this plan will help or inspire you to do better necks. “Profile Tracker” will be the same sizes.Īlso, check out my previous post this year about the Profile templates. These are the templates I used for this jig.įor better resolution: Save the PDF-file to the desktop and open it with Adobe Acrobat Reader.ĭownload Google Sketchup file (*.skp): NeckRouterJigV.1.1 So if you want to use it for scales above 27″ you need probably to increase the length on the frames as the router board. NOTICE! The measurements on the plans for the Neck Router Jig is based for common guitar scales (appr. But I did know that I had to do it sooner or later 😉 But I had a little resistance to do it because I know it’s a lot of cumbersome work and to relearn the SketchUp tool again. And over the past years, I got some request on a plan for this jig. Finally, I finished the plan for the Neck Router Jig! A flexible tool that helps you to create/re-create your favorite necks, or to do more advanced asymmetric neck shapes that otherwise can be time-consuming.Ībout two years ago I finished the Neck Router Jig and did a post in Swedish about the idea and how it works.
