<p>Hi, when I mentioned that I had the bass rod repair welded I mentioned TIG welding. TIG apparently uses less heat than other types on such a small item.</p>

<p>Just for those who might be facing the same search in the future, and to reply to Larry’s suggestion; I did reach out to both Martin USA and Sigma (now owned by a German company) and neither have any info on older Sigma (or any Sigma in Martin’s case). It seems to be solely dependent on communities like this one for info sharing. So similar to the Fender/Squire relationship brand-wise, but more detached wrt support.</p>

<p>I'm in very late on this but wasn't Sigma a CF Martin economy import line? Maybe they can help with a direct replacement.</p>

<p>Just to close this off, I visited a couple of friendly repair techs at local dealers and wasn't able to locate a M6X1.0 thread truss rod nut for a Korean DT-4 Sigma acoustic.</p>

<p>Oh well, good thing I have that membership; with a November discount and free shipping it wasn't too much to get a suitable replacement.</p>
<p>The threaded section of the new nut is perhaps 2mm shallower than the original, but will add a washer if this causes a problem. </p>
<p>Still hanging onto the old nut till I convince a friend to get a MIG setup, then can try putting a cap head socket onto the old rounded truss rod nut as Taff suggested.</p>
<p>Now just need to get some 1/4" fuel line and I can set up my low tech neck joint steamer (pressure cooker, water trap, and ball inflator needle)...<a href="https://storage.ning.com/topology/rest/1.0/file/get/9882807097?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/9882807097?profile=RESIZE_710x" class="align-full"/></a></p> Hi Mark, I just thought I wou…tag:fretsnet.ning.com,2021-11-14:2177249:Comment:2826182021-11-14T22:29:06.235ZTaffy Evanshttp://fretsnet.ning.com/profile/TaffyEvans
<p>Hi Mark, I just thought I would show a possible remedy if all else fails.</p>
<p>I used to do this 45 years ago when having to make my own truss rods. I used a brass threaded rod with the thread removed. I think the photos will tell the story. I did this recently when repairing a custom bass rod, only I had the new bolt tig welded.</p>
<p>Good luck Taff…</p>

<p>Update</p>
<p>Stewmac sells a u channel truss rod with this M6 nut, but does not sell the nut separately (part #1177). </p>
<p>Nextgen guitar here in Canada might be in the same situation, and are currently checking.</p>
<p></p>
<p>One of the tech guys at a local dealer MIGHT have something in a drawer somewhere but I need to come by to have a look.</p>

<p></p>
<p>- visit and root through parts with some local techs</p>
<p></p>
<p>The only consolation, seems to be that I cannot find a ‘close’ SAE thread size, so fairly certain that this is an M6.</p>
<p></p>
<p>Who knows though.</p>
<p></p>
<p>In any event more delays than I expected when I bought this DT-4, which may be headed for a reset once I source a steam needle.</p>
