How can a table saw cut a curved truss rod channel? 

I have severe adhd and I had your videos playing the last half hour or so and I finally understood how to do the truss rod and I fixed my fret buzz thank you so much.

For those asking best I can tell these are the measurements he listed: Nut-3/8” 1st-13/32” 3rd-7/16” 5th-15/32” 7th-1/2” 9th-15/32” 12th-15/32” 15th-7/16”

Dan, in 65 years I’ve met very very few people with your ingenuity, skill and genuine love for your craft. By the way, the Orpheum banjo guitar is flawless

Love what your doing here. Using the concept of a boesens Compass to cut your arc. Actually cutting a template arc is superfluous. You could just make a triangle that fits in your arc to the same end, strait lines being easier and more accurate to cut. Thanks for all your great work as a luthier and educator.

My dad purchased that very model saw the year I was born, now it's mine and I use it often to this day! They don't make em like that anymore! ;)

Nice jig Dan! It is helpful to mention that the deepest part of the curve needs to be as close as reasonably possible to the back of the neck in order for the rod to work best. So it is good to know how thick you plan to shape the neck before you determine how deep to cut the channel. 3/32" from the bottom of the channel to the outside of the neck would be my choice.

Dan is Legend. .

I love this stuff, these guys are so creative with their solutions.

I've been trying to go to bed and keep seeing interesting titles for videos. An hour later and I'm still binging.

Very cool technique, thanks for sharing!

Good Job Dan!

Extremely cool to watch! Just above my pay grade. Very fun to watch the videos and learn more.

I think you could have a very successful career in luthierie and not know even half of what this man could share with you in an afternoon over coffee. This video is brilliant

I squirmed a little when he put his fingers over the blade. YOU'RE SMARTER THAN THAT, STEWART!

Fantastic new knowledge for me! Thank you Dan! You have helped me tackle a number of problems regardless of the fact I am not a luthier - though coincidentally I make control knobs for bass guitars for F Bass. Thanks again Dan!

DAN YOU ARE THE MAN, ONE OF MY FAVORITE PEOPLE BUT PLEASE USE PUSH BLOCKS OVER A TABLE SAW BLADE. WE NEED YOUR AWESOME HANDS FOR FUTURE VIDEOS. THANKS FOR THE AMAZING IDEA AND VIDEO.

Hey Dan the man, you can use a 3/16" chipper blade from a dado stack and do that channel in one pass. Yes I realize chipper blades aren't meant to be used by themselves but it's no big deal to do a couple of truss rod channels with it I do it all the time and it works great.

Great Dan, I was wondering how to use my single rod trusstods, because I think they make lighter necks, and this video just did it. Thanks!!

That is genius.

Dan, you are a true genius!

Dan is THE MAN.

Would have been nice to see how he handles fabrication and installation of the curved filler strip that is inset in channel and sandwiches the truss rod.

That was awesome Dan! *Mind blown... Thanks for sharing. I never even heard of such a thing, but it makes perfect sense.

Dan Erlewine is the god of guitar work.

great how-to video instruction

Dan, I think you have forgotten more than most people will ever know about building and repairing guitars.

What about the piece between the truss rod and the finger board that actually makes the the neck bend backwards. As shown on the old Gibson neck, it is a channel, not a ”valley”…

Absolutely brilliant!

Very cool ! thanks for sharing your knowledge and techniques.

Cool idea. I'd probably still use a concave router sled.

Dan is brilliant

Great work, and many thanks for posting.

It would been nice to see how you cap the truss rod with the wood strip part II maybe?

Can this method of curved truss rod slotting be used for any guitar/mandolin/ukulele, etc.? That is one trade secret not many people know about. Good job Dan! Thankz

Awesome! Serious skill and experience.

Do you have to put a corresponding curved piece on top of the rod slot under the fret board to fill the extra gap?

Thats a chonky neck lol amazing what it looks like before till its finished great stuff

Well taught. Thank you.

Great video. I would love to see you build a guitar from start to finish. Thank you for sharing your video. I hope you have a blessed week.

Great idea! Would be great to do this with a traditional Fender style, but the skunk strip never goes all the way to the ends of the neck. Would love to see if Dan has a solution for this.

Great. Thank you.

Hey Dan! That intro music sounds great. Tell me what, where, and how...Please...?

Good job. I subscribed the channel. Cheers.

Now how do you set the rod already curved into de slot and hold it there till you glue de fretboard?

Hi folks. I pulled the measurements from this video to build my curve. It seems off. 1/2” at the seventh. Does that make sense?

Cool idea. Much quicker to build that jig than a router jig.

Very slick

Is it really necessary? Won’t that truss rod only operate in one direction? What if you need some back bow?

How did Gibson do this originally? Did they use a similar technique? Just curious.

Very nice. Thank you!

Pure genius

Although vintage Gibson truss rods were in a straight-tapered slot this is still a very cool technique

Is it possible to install a truss rod on an old guitar that doesn’t have one?

This idea will work just as well on a router table but with more control, accuracy, and safety.

Wow, I would not have my hands on the neck while cutting! Of course Dan is pro but for me, this would be too risky.

👍 awesome.

Wow

Genius!

How in the world did you come up with that?

Wow! Not only a good idea, but the first one I've seen in ages from Stew-Mac that wasn't just an ad for some gadget they're marketing that you can buy for 70% less at Harbor Freight. It might be the apocalyse...

Surprised me to see an old cheapo Craftsman tablesaw in your shop. I would have expected to see a Unisaw or Powermatic.

From what I saw on every gtr manual book, the trussrod goes the opposite way which is shallow in the middle. This vid is confusing me.

Dan is the master. But I watched this 3 times and didn't see what the Height/Dist. measurements were for that Gibson neck. Did I miss something?

"And remember this - there is no more important safety rule than to wear these safety glasses!" - seeing power tools used in this episode (and Dan's shirt) I was hoping he would say that ;)

Thank you Sir. :) Sincerly, r.l.g.iii.

Why things get so easy only for Dan?

Great video, how can anyone give this the thumbs down????

Post tension concrete....

Do this method would apply to the 2-Way Truss Rod (www.stewmac.com/Materials_and_Supplies/Truss_Rods/Adjustable_Truss_Rods/4mm_Allen_Nut_Hot_Rod_Truss_Rod.html)??.... Or Do this need a straight channel instance?

galactic brain level

Just think how awesome this would be if they actually shared all the required dimensions so that everyone doesn't have to saw a neck in half to acquire.

Dan showed but didn't. Because it did not clearly inform the measures. This video was of little use. Unfortunate.

Im not a fan of this technique. I like using a skill saw

Does it actually matter if there is a curve? I've been thinking about it and I'm not sure if the curve would impart a significant load. The knee jerk reaction is to think "yes, that would work". But I then thought, what is the load, how is it applied, what is causing bending in the neck and how will the shape and tension on the rod generate load. Applying tension to the rod will cause it to want to straighten or reduce the deflection. That, in theory is the advantage to using a curved rod. Because the rod is curved, the mid point would generate the greatest side load, a bit like a wire in tension. But how much load? My gut tells me this is going to be a very small value as the load applied on the rod is not great and the deflection small. www.calqlata.com/productpages/00040-help.html If there is evidence that this makes a significant difference, I'd love to hear about it. Unsurprisingly, I am an engineer and this sort of thing will likely rattle about in my head for a while before I am compelled to do the math and resolve it. Eccenticly loaded column with a side load imparted by a catinary that is also imparting an eccentric load on the same column simultaneously about the neutral axis of the neck... I suppose. Look what you've done 🙄 I just can't help myself...
