Hey Robert, thanks for the opportunity to come into your shop via the internet. I really enjoyed this video and will end up modifying the current jig I use. While watching your video when trimming the tenon, I was thinking that rather than taking the neck out to adjust for the angle, why not just momentarily replace the tenon template with the mortise template. Hog out the angled tenon now flat with your template, exchange the templates and slide neck back up and now you are ready to continue

Bill, If you recess the t nuts that hold the template in place for cutting the body mortise you can get the body closer to the plywood table where the template is. My jig doesn't have the t nuts recessed and I am able to cut a 22mm mortise with no problem. I am using a 1/2 inch straight cut bit with a guide bushing with an I,D. a skoshe larger than the bit diameter. Hope this helps.

Thanks for this discoursive attempt to explain how to use this jig to do a dovetail neck joint,. I have viewed the more recent video on the neck joint jig and wondered how you could so blithely say that doing the dovetail joint is similar. The geometry of the joint is so much more challenging than the bolt on m&t!! Not sure what else to say, but that a video explanation of "dialing in" would be greatly appreciated. Learning how to set the tenon in relation to the mortise template, if there is an algorithm to make this possible, would be extremely helpful. Your process of adjustment down to a fit is what I have to go through for each joint, it seems, and it would be VERY helpful to have more guidance on how to get closer to a fit after routing a mortise and then a tenon. How does the Martin custom shop do this???

I have my students set the templates on the dovetail so that the neck is proud of the body. This way they gain experience using hand tools to slowly set the neck into the cavity. You also do not run the risk of trying to get it perfect out of the jig and finding out that it is sloppy in the joint. So, as you do a few necks and gain confidence you can dial the fit in by slowly adjusting the templates so that you get closer to a final fit right off the jig. I do not recommend it on your first attempt though. Hope this helps.

Hi Robert: Another great video as usual! I am in the middle of what will probably be my one & only guitar build (Martin style Dreadnought) & don't want to go through the hassle of building a complicated jig like that. So, is there another way to cut that Dovetail joint, other than by hand, that would still get the job done & not involve using a jig like that? Do you have a video showing how to do it? Thanks for your time, Steve

Great jig. Surveying the final joint, there's very little gap between the end of the tenon and the bottom surface of the mortise (if any). On your guitars do you leave any provision for getting a steaming needle in there anticipating future neck resets?

Hi Robbie - I have been trying to get my head around the selection of the router bits for this process. I have come to the conclusion that the first cut depth with the straight bit is dependent on the length and size of the dovetail bit for the second cut . Also the diameter of the dovetail where it meets the shank must be the same diameter as the straight cut bit as it needs to start the cut where the straight bit left off. Is my summary correct ?
@troublemaker8683

Robbie, would it make sense to add a bridge-thick-block on the aluminum angle rod just at the point where the bridge would sit on your body? This way the gap is always compensated for? Great video as always!! Thanks!
@OBrienGuitars
6 жыл бұрын
I do not think so. At the point of setting the neck there is no fretboard attached. I therefore am not taking that thickness into consideration at this point. I am only concerned about the gap at the bridge without the fretboard.
@troublemaker8683
6 жыл бұрын
I understand you point, maybe I phrased that wrong. If a 3.5mm gap is desired at the saddle (during jig setup), maybe put a 3.5mm block on the aluminum at height=saddle location?

Robert I have built the ``flux capacitor M&T jig`` and am ready to go. At least I thought I was. I cannot plunge past 1 cm if using a router bit template bushing. I dare not make a cut without the bushing for fear of spoiling the template. What straight bit are using for the mortice. I figure I need about 4.2 cm plunge to make a 2 cm mortice. The template sits 2.2 cm above the guitar body by the time its`thickness and the plywood is taken into consideration.

You are correct. The neck angle is not at 90 degrees to the body. I explain the neck geometry in my acoustic guitar construction course available on my website - www.obrienguitars.com/courses It is very important to get this geometry right if not your bridge and or saddle may not work properly to get the action you need.

So question.. I noticed you took poisons to set the neck angle on the jig. Then by eye, you looked at the uneven gap at the template, and docked off the end of the neck on the chop saw. The fit looked good, but isn't that cut at the chop saw now dictating the angle of the neck to the body?
@OBrienGuitars
9 ай бұрын
The chop saw cut on the end of the tenon is just an approximation because the tenon doesn't bottom out in the mortise cavity. You want room for expansion.

@OBrienGuitars it wasn't a cut on the end of the tenon. Didn't you cut off the entire end of the neck that wasn't flushing out with the template? The part that meets the body? What am I missing? And btw I appreciate you answering, you do nice work!

There appears to be alack of understanding in how this jig works. It must be set up and dialed in to fit the neck specs for the guitar you are building. It is also much cheaper to ship in an un-assembled state rather than fully assembled. For the price it is not asking much for the end user to assemble the jig.
