Thank you Vincent for this excellent suggestion! In this video we model a perfect acoustic heel transition in Autodesk Fusion 360. No 3d Sketches, T-Splines, or any funky geometry. Just a couple sketches and some clever use of the patch tool.

Fantastic as always Austin!

@LiuteriaMarcellan Год назад

Hi Austin. I'm a professional luthier that have worked only with my hands for 15 years but now I've bought myself a CNC for doing a lot of stuff (I've always been a DIY Geek) but also guitars of course. I build Classical Guitars and I've never though I would have e found such a grat source of inspiration and detailed explanation. I've learned a bit of Fusion 360 because I've used my 3D printer to print some templates for headstock, heel, neck section...but this is on a whole new level...can't wait to try to design and create my personal Neck design. Thank you so much. I'm a fellow RU-vid content creator so I really appreciate the time and effort you put in this channel!

Thank you sir! One comment for the folks at home. the dovetail normally tapers, with it being wider near the fretboard than the heel, rather than parallel as shown. But if you’ve managed to model the neck this far you probably don’t need a other tutorial to show you how to do that.

@austinshaner 3 года назад

Doh! There is always at least one mistake in each video :P

@konsaw Месяц назад

Is it possible to show how you design a neck with angled headstock? Also with the long holes for classic guitar mechanics? That will be really cool!

@ImagePaint-InlaySoftware 3 года назад

Austin, excellent video! The shape of this heel is exactly what I was looking for. Like you said, the patch tool becomes very powerful with the helpers. Thank you for your time and prompt response to my request. The hardest thing to model for an acoustic guitar is this heel. I am ready to CNC!

@austinshaner 3 года назад

Fantastic! I'm glad this helped you Vincent! It was a pleasure talking with you - Now go make it! :)

@alexanderkartsonakis 3 года назад

Very very nice!!! Not the subject of this video but I was always wondering how on earth is this type of heel comfortable for acoustic/classical players. If you check out the ibanez Steve Vai for example, that's exactly how I'd do it 🤷🏼‍♂️

@austinshaner 3 года назад

I honestly never even notice it really on my acoustic anymore (similar style heel). You kinda learn to play around it.

@hveguitar 2 года назад

Amazing stuff, Austin you're the best Fusion tutor on the web for sure, thumbs up!

@dantahoua 3 года назад

That's great. I will try it with my design and add a back heel angle. 😊

Great Video and techniques, clean delivery as well. But I do have a challenge for you: Violin/Cello neck scroll, CAD and CAM. I have to admit, I have a high personal interest in this suggestion lol

@austinshaner 3 года назад

oooh, that sounds like a fun challenge!

@ImagePaint-InlaySoftware 3 года назад

Austin, I am thinking about how to partition the neck for CNC and my thoughts are: - For the heel, cut it in half and CNC it separately from the rest - Cut the stock at the same angle the headstock is in relation to the neck and then plane the two surfaces flat for gluing later. For CNC either: A. Glue the headstock and the neck and then CNC B. CNC the headstock, CNC the neck and then glue them. What is your take on this?

@dantahoua 3 года назад

Thanks!!!! 😊

@Leogbass 3 года назад

These videos are great! Thanks a lot, would you consider doing a fender style neck? Cheers

@austinshaner 3 года назад

Thanks! And definitely!

@Vinyari Год назад

Is it possible to cut the heel into two pieces so that it could be cut on a machine without the z height capabilities and then glue the pieces together after? possibly cut in dowels for alignment during glue up?

@Vydysh Год назад

I found some important updates for this solution

@jeffnobis872 8 месяцев назад

Hi Austin, thanks for another great tutorial! I've been successful in completing the heel transition model up to the point of creating the patch (16 minute mark in the video). I'm able to select the 4 edges and set curvature from the drop down. When I add the curve for the heel cap it appears in the list with the edges, but the OK button to execute the patch isn't enabled. I'm not getting any error messages... Any thoughts??

@spannerman4886 3 года назад

Austin thank you for these excellent videos. Having retired and built my first CNC I am new to all of this so i'm back in school😀. Could you possibly do a video on making a multi scale guitar neck and fretboard please? I have done some work on drawing a neck and trying to find ways of creating headstock and heel transitions and I'm enjoying the journey. However I cannot find a way of producing angled planes though the neck and creating the multiple fret spacings for a multi scale guitar. Any help would be much appreciated. Best regards

@austinshaner 3 года назад

I plan on doing a multi scale neck /headstock video at some point. This really complicates how we draw the headstock so it's definitely tricky. .I've added your request to my list!

@@austinshaner That would be brilliant I have used the Find fret 2 as well it's really good, so thanks for teaching how to import and use it, I found that a problem.

@WeepingZeeGuitars 3 года назад

GREAT Video- Extremely helpful! How are you cutting this? Thinking you'd need to start with fretboard face up to do headstock face, then flip on each side to do heel and dovetail/tenon, then face down to do back of neck, volute and back of headstock...

@austinshaner 3 года назад

This would definitely is tricky, particularly if you don't have the Z height required to machine it as a single piece. Your instincts are correct. You would not want to machine the back side first as then it would complicate your work holding. I would machine the truss side first so you still have a flat surface to mount to. Flip it over, then machine the back side. And if you don't have the z height clearance, you would need to likely scarf joint the heel portion so you could machine it separately then glue it up.

@beak85 6 месяцев назад

Will this still work if you used the control point splines for the neck shaft in your other video?

@tdeaguirre 2 года назад

I like a lot your approach to the heel transition and I think is perfect, but I have one problem to manufactured in Fusion 360 using my Shapeoko 3 XXL CNC machine, the clearance for "Z" is 3 inches and my heel is 3.75 inches. I will need to break the heel in pieces to do the milling uhnless there is a way to turn the neck sideways and mill in that position. Do you have any sugestions or ideas to do it.?

@austinshaner 2 года назад

Hi! Your thinking is correct. With a limited z height like your shapeoko and my xcarve, we are limited to either a 2 piece construction or side milling. Both are common solutions and will work. For side milling you would machine one side, flip it, and machine the other side to match. Look up Ibanez factory tour, this is actually how they do their acoustic necks, albeit with much more expensive Machines :)

@tdeaguirre 2 года назад

@@austinshaner I saw the video and it only shows how they do it, it does not say much because is only carbing the neck and not the heel. I am still confused if I should do it sideways or split into pieces and them glue. Any suggestions in how you will do it?

@ImagePaint-InlaySoftware 3 года назад

Austin, the heel transition is very smooth if I use arcs for the neck profile. But, if spline is used for the profile, the transition at the neck dips gradually starting from the neck center (neck profile center) toward the top where the helper (extension of the profile) is. You said in the video that it is best to use arcs, is that your reason to only use arcs?

@austinshaner 3 года назад

This is a much bigger topic than I can explain in this comment. But essentially yes. If you want a constant radius from one point to another, you should use arcs. I almost never use splines for anything unless it's geometry that can't be defined by lines/arcs/constraints. The video this weekend will be covering this topic more in depth.

@ImagePaint-InlaySoftware 3 года назад

@@austinshaner It is sad we have to use arcs, since custom guitar makers do offers verities of neck profiles and arcs cannot be used for most neck profile they offers. Also, neck profile for standard classical guitar cannot be created with arcs. Nevertheless, I will continue trying to solve this problem using Fusion 360.

@austinshaner 3 года назад

Sorry, I misunderstood, it's not required that you use arcs to get a good result, i just meant if you want a constant radius. The problem(and benefit) of splines is that they allow a variable radius along the edge. So unless you spend time refining that spline you may get some dips here and there

@ImagePaint-InlaySoftware 3 года назад

@@austinshaner I did spent a lot of time using spline, extend it to create helper surfaces, I can confidently say that the method of using patch and helper surfaces does not work well with spline. This is inherent in the patch algorithm in the software itself which can be improved, hopefully in the near future.

@austinshaner 3 года назад

@@ImagePaint-InlaySoftware I'm sorry to hear that. If you send me an email with your file and or the neck profile you are after, I'll see if I can get it to work, either with a spline or arcs that achieve the same shape.
