I thought this was impossible. How to create PERFECT headstock transitions. 

Hey everyone, I made a huge mistake in this video that is likely to cause you some trouble. This was just a prototype to get this method working, but I failed to take into account the neck taper. My assymetric headstock transition video addresses this, so check out that video for more details. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N8VcumXW41Y.html

I have been following your progress and up to this point, I can say for certain that you have the engineering skills most engineers would die to have.

You have no idea how much it means to me that you make these videos…you have helped me in an unmeasurable way. Thank you very much for your hard work and sharing it in such an amazing way!

Hey Austin, I just want to say thank you. I’ve watched so many of your videos and rewatch them frequently. By now, I fully understand many of the concepts you discuss, but love revisiting them as refreshers. Your pacing is perfect. I came here because I wanted to learn about modelling guitars but these concepts are useful for so much more.

Intersection curve 👌

WEYYYYYY well done for sticking at it! Honestly, the results you got last time, most people would have called it done. You're not most people obviously haha

This only fragment of the whole Fusion 360, and named differently..., like "Headstock Fusion" can be sold to the guitar making factories, so that they can make a new headstock every day or every hour. Amazing work!

Yes! That is the PERFECT transition man! Really great stuff. Thanks for sharing it with us.

I can tell immediately this is going to help me enormously. I'm new to Fusion 360, but I've been doing guitars in Rhino for many years. I'm so glad I came across this video just now. Watching it for the second time, and working through. THANK YOU.

Thank you Austin for sharing your experience and knowledge. These give us good idea about using tools of Fusion 360 in 3d guitar design.

Absolute genius sir, well done Your hard work will defiantly help the world of guitars

This is great. Learned a lot of fusion tricks that I’ve been wondering how to do. Thanks

Man this is genious! Thank you very much for sharing!

Fantastic job! Wish this had been around a few years ago when I first tried to learn Fusion to make a guitar. It would have made my life so much easier. I'm just a hobbyist with no where near the level of knowledge and talent you have. I remember the difficulties of trying to create the transitions at the neck and heel. Now that I look back I wonder how I managed to stick with it. Haven't built a guitar in 5 years but after seeing this I may try again. I can appreciate the amount of time you spent and you have my sincerest thanks.

Such a great solution and decently simple, I appreciate you sharing!

Amazing! Thanks so much for sharing all these videos. I’m a beginner and these have helped a lot. One thing I’m struggling with right now is doing a binding channel on a body with an arm relief cut.

🤯 great video, thanks for sharing, and explaining it in a way that is easy to digest

This is FANTASTIC

Thanks for this. I have been working on this on and off for about a year. Missed just a couple of points that make such a difference. Cant thank you enough for sharing this. Please keep going with these videos.

Thank you thank you thank you - this takes the fear and confusion out of one of the parts of building I would love to automate in the near future. I can throw away my wood rasp, but not before I get a program working You HAVE nailed it :D

Amazing, and yes, you nailed it! Great job!

Great job! Thanks for sharing this technique

Thanks for this video...I didn't know how much I have yet to learn, and apparently its quite a lot!

Your tenacity has paid off. Looks like you nailed it. Congratulations on the new addition to the family.

By far the coolest fusion tutorial video I’ve ever seen in my entire life! 8 million out of 10! My jaw as dropped the entire time 💯 💯

Vary nice ! I have been struggling with surface modeling for a while now, and I have been looking at both of those channels a lot . In this video you really made things more easier to understand , and I really appreciate the examples you gave . I would much like to see more surface modeling videos, or any more tutorials you have from start to finish .

Brilliant! Genius! As a luthier who has been beating my brains out coming up with all kinds of attempts at this....I salute you!

Wow 😮 Consider my mind fried 😆 That is seriously impressive 👍

I learned so much from this one video!! Many thanks :)

thank you! Love your videos.

I have pounded the keys, I have paced the floor. I will not do that no more. hum. So, not only did you cut through a lot of BS and help a bunch of us grow, but i think you inspired a good blues lyric. Thanks.

Bravo, Maestro! Nailed it! You got yourself a subscriber.

What an awesome tip!!! Thank you so much for sharing!

Great tutorial here! This is exactly what i've been trying to do with Aspire but just can't! And since there is not much information around for Aspire i'm giving Fusion 460 a shot! Thnx for sharing this!

Hey man! that is fantastic! I am an architect I started at 90´s with 3ds max, haha so vintage!, but this thing you did is really fantastic!, starting froim 3 2d scketches as monge´s method make this har topic solved with less operations, customization and perfection! thanks for sharing!!

Austin - excellent job! - I have been wrestling with this EXACT thing for the last 6 months. Being a veteran of both SW and Inventor, I was struggling with the tools available in F360. I recently did a career pivot (thanks pandemic!) and now work for a prominent guitar builder in Nashville. I quickly found out the these headstock blends are no joke! This approach is clean, clever, and still parametric - cheers to you!

Amazing thanks a lot

REALLY excellent stuff here... thank you so much. Going to try this now.

Wow, you have taken the intersection curve command to a whole new level! I have learnt a lot from this video. Thank you for the shoutout as well. I was wondering if you could share a link to the file with the sketches. I would really like to do some practice with it while following your video. I can understand if this is proprietary information though.

OMG! You are a true wizzard!

Hi Austin, Well done. Your videos are very clear and professional. Why don't you make another nice video on building the whole neck of an acoustic guitar?

Hi, what a truly wonderful solution thank you. I have modelled and machined many satisfactory guitars using my own clumsy transition but yours has taken this to a new level. I have just modelled and simulated the roughing and finishing toolpaths for the headstock transition and this version is superior. No gouges or weird machining marks I have had to previously contend with. I have a couple of troubleshooting tips. For example I spent hours extruding the guiding curves for the patching operation. However, in order for this to follow my tapered neck reference, I actually had to loft between two neck shape sketches. I cannot understand how you seem to have extruded a taper! I have a couple of other problems I spent hours getting around but actually managed to do so [I used and asymmetrical headstock shape which was more troublesome.] If you have time and inclination, I would love to discuss this more by email with you, as it may help others tool. Please hit me up through here or PM me through my Facebook page if interested. Otherwise, thanks so very much for your comprehensive work and selfless giving away of your IP!

I like the way you do that! I also work only on half of my neck / body, I found it easier. I use a lot patches and surface too but also loft. My methos is very similar as I want to have perfect smooth transition. I'm still struggling with my arched top cutaway and the heel of my acoustic but your intersection use give me some ideas!! Thanks!

Hero.

very helpful. How do you hide the seams between each patch?

My hero! The last video was great, but this is game changing. Next video needs to be on acoustic guitar heels. BTW, have you played around with the neck profile sketch being a spline instead of an arc. If so, does it affect how you draw the “helper” surfaces.

Hi Austin, thanks again for your great tutorials - based on this one and your intro to parametric modeling I’m building an adjustable neck model, bit by bit. The fingerboard works a treat (adjustable width, thickness, compound or fixed radius). Where I’m running into problems is something that’s probably idiotic, and likely due to using the wrong tool or wrong constraints - I’m mostly using arcs (3 point, because they’re easiest to draw) for the curves on my headstock contour and volute. The problem I’m having is I cannot adjust the radius on any of said arcs. It’s displayed in the bottom right corner when I click on them, and that’s it. Or I get a warning that I’m trying to overconstrain the model. I’ve used construction lines to set widths and lengths for the headstock and constrained the vertexes to those points, so outside outline are adjustable by adjusting those values and it works smoothly. This is probably why I can’t adjust the radius manually for that. But for then volute outline, which I’m doing as three arcs with tangency to the outer points, each other and the line at the nut (apex of the volute) I can’t adjust the volute radius either. A pointer in the right direction would be immensely appreciated…

Bravo man. Really impressed. I am currently building a Gibson Explorer type guitar. It has the “hockey stick” type headstock. That design uses a 13 degree tilted headstock. Would this approach still work for that style of headstock? Great work on this. Much appreciated

Hi Austin, you can share this sketch for training ?

Hey Justin, I tried your method to make a heel for an acoustic guitar and hit many walls. I am almost at a point where I think your method is not appropriate for this type of work. Appreciate for any help on this.

Austin. I am having trouble executing the fist patches. My neck has a taper and nothing wants to line up. My question is do you have your neck profile in the sketch starting at the nut line?

Any tips on common failure points why this would not work? When i try this I end up with curves that are acting like they don’t connect but everything looks right (checking coincidente and all). The result is that when I start patching, some edges aren’t letting me select them to complete the patch geometry.

Question: Since the neck itself is not parallel but slightly “fanned”, will that affect the transition from your headstock drawing into the neck? I hope that made sense…

Can I pay someone to do this for me? Having trouble getting any point to connect to each other, so everything is in different locations on each plane. It's been impossible to line anything up and the sketches won't connect to each other.

To bad it isn't with a neck break angle as well. Very few guitars have straight head and a valute

This is so much better than every other tutorial on this process and the end result is obvoiusly great. I think if you wanted to be really picky about surface quality, the patch should be tangent only to center line surface reference since it'll be mirrored. Once you mirror it you'll have g3 continuity automatically I believe. Its demonstrated extremely well here. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BFHaQGhxURs.html#19:09 . I'm curious if there is a way to do this with loft instead of patch.

Unfortunate that this method doesn't work if your headstock is angled. Intersection curve projection projects circles an arcs correctly but not splines and lines. Splines and lines are projected as they were not angled?. Probably a bug in the software. Work around is to project the headstock outline to a surface.
