This is a demonstration of a guitar neck contouring jig that I recently finished. I was trying to replicate the exact dimensions and feel of a 2001 Reverend Eastpointe neck for a customer...and I wanted a way to do it not only once...but be able to repeat it over and over with absolute precision. After doing extensive research on the internet, I found a couple jigs that others made that I really liked...but wanted to combine the features and customize it some to the available tools in my shop. The first one that really impressed me was from a RU-vid video by Pederson Custom Guitars....look it up...very impressive. The second one was produced by a gentleman in Canada...Bill Scheltema (who now has a RU-vid page)...and published his design on the Telecaster Guitar Forum (www.tdpri.com).
I took ideas from each of those previously stated designs...then added my own flare. The replaceable template pucks allow for unlimited neck contour design options...and have given me accuracy and repeatability...while saving a lot of time in the production of my handmade guitars.
I plan to continue posting more video of my adventures in custom guitar building and interesting guitar mods. Thanks for watching...and don't forget to subscribe.

Within the next couple weeks I'm going to post another video using this jig...and I'm am also going to include information on how to shape the neck by hand. Seriously, on your first guitar....you should learn to do it by hand tools. Then the jig will make better sense after you understand the hand tool process. Maybe later this summer I will break down my neck contouring jig and show all the pieces, parts, and dimensions of everything contained within my jig. Maybe someday I will make full plans on CAD...but until then...you guys should be able to reverse engineer after seeing all the parts separated. It is getting close to a full year now that I have been using this jig...and it has held up great.

@budddhat 4 года назад

excellent! I have been pondering a fixture to shape necks. I had been leaning towards the neck being fixed and the router in a sliding & rotating carriage. Your way seems quite practical, thank you!

Thanks Andy. I try to share things I do...but it would take a full time video staff to share it all. I'd rather be building guitars than spending too much of my time in post production! But feel free to make requests of tasks that you think are not covered well enough...I will try to share the techniques/tools I use.

I still like Texas Toast method of using a roundover bit with the bearing running along the fretboard edge and finish sanding after.

There was another RU-vidr's video on how he made ramps for his contour jig to do away with most of the filing of the headstock and heel.

You really need to get a PAF (no, not the pickup. lol) and market this wonderful piece of machinery!!! I totally agree with the "learn to do it with hand tools", like you say but even so, there's so much time saved to be perfecting other parts of the project. I'll be mimicking (hopefully w/ success) this design soon! :)

Awesome jig! How did you arrive at the shape and size of the template blocks that determine neck shapes and taper between nut and heel?

@maximumguitarworks 3 года назад

I started with a pattern I found on the TDPRI forum...then adjusted as needed for my desired specs. I think the info on where I found that drawing is in my video description.

@mtc7776 6 лет назад

One question : Is there a reason to make contour templates bigger then the actual neck contour ? Wouldn`t it be easier to make them same size or am I missing something ?

@maximumguitarworks 6 лет назад

Try it and see if it works. To me...it seemed like there were some mathematical relationship that has to happen that is something other than a 1:1 ratio. The initial templates worked for me...so I just keep using them...changing the templates by actual differences in other spec necks. But if you figure out an easier way to do it...I'm all ears!!!

@stevefpv4669 5 лет назад

Very nice concept and demo. I also like the idea of the acrylic cover. I'm building a neck back contouring jig also, it's gonna be a bit different, but I'm struggling with how to make the templates on each ends the bearings run against. It seems if I make templates that have the same radius/shape as what I want the neck contour to be at each ends the result are off, so I guess I have to add an offset to the templates but not sure how to calculate that offset. If no offset is needed then maybe there is something else I'm doing wrong. Any helpful hint would be greatly appreciated. P.S.: i know people will likely tell me to use a cnc machine, i know i have one and it's doing great, but my opinion is that a jig like that is still very useful and not obsolete when for instance you want to achieve a specific shape result quick without spending hours in front of screen designing a model for something you're probably only gonna build once or a few times.

@maximumguitarworks 5 лет назад

I hear you on the whole CNC thing. I wish I could help you more...there is an offset to it. One of my previous replies here went into as much detail as my brain can handle. I worked on the offsets till I had my standard neck I liked, then my changes were a 1:1. The template should start off about .5 mm from the edges of the fretboard at a given bit height. Then you can figure out the size of the template for the neck side and heel side profiles. Look through my previous replies...I think I gave more numbers.

@stevefpv4669 5 лет назад

Thanks a lot for your kind reply. I've found what you were referring to, omg, sorry my bad, should have checked the other comments in more detail. This will help, I guess I can take it from here. Much obliged.

@KnottyBurlWoodworks 4 месяца назад

Do you have project plans available for purchase so I can build one?

@RalfGlaser 7 лет назад

Great concept, thanks for sharing. I'm actually trying to replicate this. What I don't understand is how you form the round templates that give the neck its profile. Duplicating the extremities of the profile doesn't work for me, since the templates are located outwards. In that way I'm not getting the right angles where I want to rout. Seems that it needs some kind of projection for giving the templates their correct dimensions. How do you achieve this? Thank you in advance for any advice!

@maximum303 7 лет назад

Ralf, thanks for the comment and question. Most of the answer is contained in my reply to John below. I have received this question before. I may not be a mathematician enough to give you a scientific answer. However, I will tell you what I know. I did a lot of research when I was looking to build one of these...and basically there are offsets there to give space for the rotation of neck platform. If I measure from the center rotation hole of the puck to half of the width of the neck (at either the headstock or the heel) you have 3/4" extra to the edge of the template. If you measure from the center of the rotation point to the the 12th fret height and the 1st fret height...each template has exactly 1/2" extra to the top of the templates. Basically you can draw your desired profile from the rotation center...then add 3/4" to each side and 1/2" to the tops...then connect the points with your desired shape (C, D, V, whatever) and you with have the perfect template. So, even though I don't fully understand fully the math...I can see how it works...and that it in fact does work. Good luck with your goals....let me know how it works for you.

@RalfGlaser 7 лет назад

Thank you Stephen, I would have been lost anyway if you came with a maths formula ... you could have answered in chinese too ;-) Your approach seems logic to me, thank you. I will try to figure that out. A happy new year!

@jimmpanik3402 5 лет назад

so your center line to the cutting surface is off by 1/2". If you were to raise the cutting surface 1/2", you could make the cutting masters to scale? My idea is to use the same concept but keep the pucks scaled at 2:1 so it can make better use of finer contours. Great invention. Works well. Easy to make and doesn't cost a ton.

@SarcastSempervirens 2 года назад

@@jimmpanik3402 my thoughts exactly, this way the pucks are bigger and you can finetune them

@paulneeds Год назад

Hey Steve cool… ‘jig’? That seems too small a word really. More of a system! I guess that can work on a sort of spherical neck shape - will it handle D’s, Vee profiles etc - or would one have to calculate and fabricate the appropriate shape cams for each end?

@donjoseph162 6 лет назад

Awesome jig! Does it allow for use in making an acoustic guitar neck?

@maximumguitarworks 6 лет назад

Hey Don. The contour jig was designed for electric necks. However...I have successfully used this jig for multiple acoustic necks too. By luck I made it just wide enough...and tall enough...to fit the heel of your standard acoustic guitars. The only adjustment I had to make was to use a clamp on the top to restrict the router movement on the heel side by a couple inches. I also made new templates for my classical guitar necks to produce a slight “D” shape to the center of the back contour. Pretty simple...and has worked great for me!

@kriscullen5720 3 года назад

Do the cams compensate for the width difference between the nut end and the heel end? Trying to wrap my head around the physics of it.

@maximumguitarworks 3 года назад

They are a ratio...so yes they play a part. Don’t over think it...I still struggle to understand.

@maximumguitarworks 5 лет назад

I started using a 1/2" spiral upcut bit...don't remember the brand...but switched to a 1/2" round nose bit as I found it produced a better finish that required less sanding. Both bits are 1/2" shank for very solid and stable performance...both are made for the CNC world.

Getting ready to try and build one of these, where is the center of rotation? I can't tell from the video if its centered with the platform the neck is mounted to or slightly above it.

@maximumguitarworks 2 года назад

I gave a lot of details in some of the older comments...might want to look through those. But it is basically at the top of the neck blank. Since mine is designed to be used with the fretboard already glued on...there is about a 1/4" offset.

I like about 3mm taper...but I can adjust for the customer. You might want to read through all their other posts and comments here. I tried my best to answer that question before...but the math is above my head. I did a lot of trial and error to get it right.

@howbouthat5479 3 года назад

How did you determine the dimension of the cams for the jig? Are they the same as a cross section of the neck at the first and twelfth fret or are they larger than finished scale? I'm thinking interchangeable cams for different neck profiles. Or do you not want to share your details?

Man...that was like a lifetime ago. I'm pretty sure I had responded to old comments with what I know...but in the end I am not smart enough to know exactly why it works. Sorry.

@nelsonpainco1368 3 года назад

one question from a noob and a guitar builder wannabe :) why do you move the router along the neck instead of set it on one end and do the neck routing by spinning the neck with that wheel and then move the router a bit forward and use the wheel again? like, the reverse of what you are doing, I think that way it would turn out a bit smoother without that much sanding to do

@guaroshadow Год назад

I tried this, it was way slower and no significant difference in smoothness.

@tylerjohnston708 3 года назад

Did you contour the fretboard before or after you carved the neck back?

@maximumguitarworks 3 года назад

Don’t remember what I did on that video. I have done it both ways...but prefer to radius the fretboard and install the frets first. Mainly because it is a little easier to do the fret pressing while the neck is still flat. My contouring jig has foam that will compress around the frets and keep the neck from rolling.

@OldSilkRoad 3 года назад

Won’t you get cleaner cuts with downcut bits, instead of upcut ones?

@maximumguitarworks 3 года назад

I’ve done other videos on this jig in the past 6 years...I’m using a different bit now. I use a 1/2” round nose. In theory a down CUT would be A better profile bit for the side of wood (or compression bit)...unless there is no where for chips to go...like a channel. However, a down cut applies pressure down. In the case of this jig...there would be constantly pushing to extend the springs that are trying to hold the platform up. An up cut would tend to pull the wood up...which would be against the rigid template pucks. There is no easy answer...or a rule that is without exception. Each case must be evaluated in its on merit. With this jig...there will always be a need to sand...same for pretty much any CNC operation.

The issue with this gig is the neck is wider on the bolt side, and narrow on the neckplate.......means you will have a gap each time you approach the upper part (I mean, there will be a flat part when neck and fretboard meet).....you fix this with files? (or I pressume the size of the round guides for the acrylics have a difference in size?)

@maximumguitarworks 5 лет назад

Yes the templates on either end are different. There are no flat spots....except for the fretboard edges...which is what you want. I wish this jig could do the transition areas on either end...but that appears to be its limitation. I suppose that is where a CNC would be more advantageous.

You still didn't adequately explain that the two end cams are different sizes to represent the tapering of the neck.

LOL You make it sound like you can just buy a CNC and throw a chunk of wood into it and magically get a neck out of it. Aside from the "simple" cost of the machine (and I'd love to see the amount of backlash and runount in a "junk yard" CNC) there's a mountain of work yet to be done in generating a usable neck CAD model and then turning it into tool paths. Nothing wrong with a simple jig.
