"one more hand..." Jerry, I had that conversation with the Lord a few years ago. I was trying to do something and said, "Lord, it sure would have been nice if you had given me another hand." The answer popped into my head immediately, "You dummy! If I gave you a third hand , you would just try to do four things." After thinking about it, I think that may be the source of most of man's troubles, trying to do things he wasn't supposed to be doing.
It blew my mind when I saw you post this. I have that same mandolin under the Ibanez name. My issue is that the neck angle is near zero and the bridge had to be cut down. So much for QC back in the 70's. I was thinking about trying your "wedge" trick to fix the problem.
35:00 -ish Monday Morning Quarterback here, but could you have put a shim down on the soundhole side of the truss rod block, put a sacrificial block of wood on the head side, and then used a bigger screwdriver or awl to wedge it out against the sacrificial block and with the shim in back taking most of the force and also providing a smooth sliding surface?
It probably a stupid question. But how come you don't make a bottom spring clamp for the heater to hold it on the neck? I'm sure there's a reason just curious.
As an engineer I assumed that the rod would be placed off of the central axis, so that tensioning the rod would produce bending. Is this not the case? That's not clear: You know how the fibers of a cantilever beam are in tension in the top part of the beam and in compression? If you tightened a truss rod that was in the bottom part of the beam, that would cause the beam to bend down.
It used to be common practice to place a straight rod UNDER the longitudinal centerline of the neck(deeper slot)so that tightening the rod would exert pull that would force the center of the neck upward
@@matthew4878 It varies among makers. When i build banjo necks from scratch, I use a deep slot and a solid fill strip. I seldom fabricate anymore, preferring to buy shaped neck blanks with truss rods installed.
D'Adarrio strings are my favorite. I had lights 9-42 electric strings for my Fender stratacaster. ????? I do have a question. ??? My acoustic guitar used to always break the treble E string. Does that mean I had a sharp edge on my bridge? It was plastic. ??????
Dumb question - can I use Phosphor Bronze Bass + Silken Steel Treble strings? Can I give one string in each course a Phosphor Bronze + a Silken String?
Hi, thank you very much for the truss rod explanation, I saw a video mentioning that old Gibson truss rods should have a under bow and not straight: ruclips.net/video/xN8YNFwfCvs/видео.html. 7:07. Take care.
Great job Jerry. You're a surgeon.
Another tough job overcome with extreme patience.
I just love to listen and watch you work Jerry I find it very relaxing and grounding.

You sure seem to get all the interesting repairs Jerry!
Pretty good job for a three hand man. Wow .
I love NOFX. Bless you my brother in arms.
Amazing mandolin surgery 😅I hope to see you fix this instrument 😃
Outstanding video Jerry. You do very nice work on mandolins.

make a holder for heater, like a telescoping light, to keep both hands free...
Been watching your work and I'm very much impressed, thank you. But what would cause a neck to have a serious twist?
Hey Jerry, could you thread a guitar string under the rod and then use like a gear puller to force it up?
I'm always astounded that Jerry spends so much time repairing $200 instruments. He's better than that surely
He charges the same hourly price regardless of the instrument value
I guess you don't understand customer service it's not what I want it's what they want

wait... hold it... i just saw something about duct tap.... that is supped to fill in gaps isn't it?....

@@r72g That makes sense to me. What do they do now? Use a curved rod? That would only work if if was supported by wood along it's curve.

This is probably a stupid question, but could a heated wire like a E string be used to get a fretboad off?

Also, I have a twisted neck, lower on the bass side. What would be an average cost of repair lol

Jerry, have you tried an induction heater to heat your knives?
yes
Maybe you meant 46 hours. Lol
Can I ask what ever happened to the “ best mandolin ever built “ ???
I discussed it in yesterday's blog live
@@RosaStringWorks sorry wasn’t around …. Just asking cos I loved it …. Amazing workmanship !

Can you say ''Another Sigogglin Mandolin !!
you should not have done that... tension... a converse solution to disease... easy....
