Acoustic Endpin Jacks - Are You Really Installing Them Right?

Common mistakes and a simple fix to keep the endpin jack from ever coming loose again on your acoustic guitar.

Best video out there on this topic! This level of detail is something lacking with so other previous “luthier” videos on KZbin. This amount of detail is super helpful! 🙏

Beautiful! I managed to install a pickup on an old $30 guitar with minimal damage thanks to you! But it didn't take five minutes - more like three hours!

Great video! Learned something!! Three suggestions: 1) a 1/4 wood dowel won't scratch or damage any wood or metal parts like a metal rod. 2) Using a piece of coat hanger wire bent to a small "L" at one end takes a lot of trial & error out of determining the inner nut position through the end block. Use a piece of masking tape to mark the end block thickness and transfer this distance to the jack nuts. 3) Use a tiny (and I mean tiny!) bit of wood glue on the inner & outer nut threads to lock them in place. Wood glue acts like LocTite; but is less aggressive. However, too much will nearly act like a weld!

Dave should have millions of views. True expert and great videos.

A BIG THANK YOU. Finally, I found the proper way it should be done. Mine is also a Larrivee😄

First time I’ve seen anything from your channel and I immediately subscribed. The clarity with which you speak about so many important details that often go overlooked is remarkable. Thank you, thank you, thank you!

[@RahulSharma_JaiMataDi]

One of the excellent videos that explains everything clearly thanks for sharing

[@vikingbeard]

Excellent to the point explanation, thank you. You do everything properly, including sound and picture, hope you'll keep on making videos.

[@smandez2023]

Yep, great tips! I struggled with a K&K recently, but that extra long dowel bit you have there is the game changer. I think I have some wooden ones around the shop.

[@harpethguitar]

I learned something new. Thank You! ❤

[@jamiegoodson950]

Loving your toolbox that’s a real deal toolbox in my knowledge.

Excellent Tutorial and it solves a long-standing jack issue. Thank You David.

[@nwcic]

Nice Tut. This will come in really handy installing a pickup in an f-hole Gypsy guitar. The long drill bit won't go into the f-hole on mine, but a stiff coat-hanger will. Thanks.

[@MaggardRazorsTV]

Great video David!

[@theloothgroup]

Excellent Video !

[@dew12u]

This is a very well done video - thanks for putting this out there!

[@gunnargubjornsson4112]

Thanks for an excellent Tutorial !! it solves a long-standing jack issue for me :)

[@roryadam]

would a rubber washer not fix this issue? I get that the way mentioned here would still definetly be a better option but would a rubber washer keep it from loosening up?

[@bsandoval230]

Your explanation was brilliant, thank you so much

[@echo8287]

Your video was good, showing attention to detail and how it should look when you are finished, But the one detail that was missing for me was, what bit or reamer are we talking about to get the perfect size hole> I need that info because I am about to install one of these pick ups on a J 45 custom shop model.I want the best tool to increase the hole to the right size. So what is it and where can I get it?

[@A2Guitars]

Sorry if I left that out. My preferred diameter for the hole is either 12mm or 15/32”, which are effectively the same for this application. StewMac has a reamer available specifically for this job, which while not cheap, is worth it if you plan on doing this more than once or twice. Alternatively you can get a straight 15/32” reamer, but you may need to open up the outer edge of the original hole to 15/32” with a Unibit before using the straight reamer.

[@leestoutmusic]

Perfectly explained. Thankyou!

[@Jamman610]

1/4” long bit? Excellent trick. I used a thin flexible wire. This is a much better idea. Thanks.

[@leoparcoeur]

Thanks for your video!

[@walterw2]

been installing endpin jacks for decades and it's simple enough... nope! this is a revelation! i've always adjusted so the nut just barely _didn't_ bottom out against metal on the principle that it got me full clamping pressure on the wood, but now that you explain it of _course_ that's not as reliable as full-on metal against metal thread-tightening and yes, i see those dished-in washers all the time extrapolating out, what about the star washer inside? i've always assumed it was meant to grip the wood directly, but should it in fact be between the internal nut and the internal flat washer?

[@A2Guitars]

The star washer is designed to be placed between the nut and washer to lock the nut. To be honest though, so long as it’s tight I doubt that part would prove to have much consequence either way in this application.

[@DonaldRoycroft-sm3rp]

Thanks, that's absolutely essential,to know 😊😊😊

[@mikemal2]

Fabulous! I have some work to do 😀

[@kmaster007]

What is that slide metal rod tool you used in this video called? Beats having to unwire the strings where the guitar's circle is for an illiterate person to. I've just watched several KZbin videos showing you how to drill a hole there to insert a point cork screw which to me is not ideal solution in the long run where this type of screw will cause that hole wood surface to crack or broken resulting from guitar strap pulling pressure.

[@GuitarQuackery]

You blow me away, doctor.

[@MVPTimothyMichaels]

Thanks!

[@johnnyxches612]

Thank you

[@inzendio]

I got a strap button that's rusty how can I remove it

[@roxtah]

Where did you get the poster with all the headstocks? I want one!

[@vlouz64]

Merci beaucoup ! :)

Hard to follow the units in 32nds and 1000ths. I don't know how y'all muricans do it
