Re: Martin N-20 Folk Guitar repair

So for the TJ System, using 3 magnets in a row, they would have to be configured: +,-,+ on one clamping side and -,+,- on the counter clamp. This would allow for the cauls to be aligned and attract one way but also allow for one of the cauls to be rotated 180 degrees and still attract. In the images...

Re: Gibson LG-0 bridge

Thanks Barry. I use a spindle sander with a fence and clamped in place stops, a combination disc with 1" X 42" belt sander and hand tools. Replacements like these are always one offs, I don't have or use any special jigs, so it is mostly freehand work.

Re: Gibson LG-0 bridge

Correction... The second bridge example was made from a blank of Madagascar Rosewood, I forgot I had done this. Both of these guitars originally came specified with Indian Rosewood. The M38 Martin was a paying project but the J45/50 is one of my own basket case projects, so I didn't get picky on the...

Re: Gibson LG-0 bridge

Yup, I second Barry's assessment, glad to hear removal went well. These are images of two different Indian Rosewood bridges that started as blanks purchased from LMI. Buying bridge blanks one at a time as the need arises for a project is always a crap shoot even though I always buy the best grade th...

Re: Gibson LG-0 bridge

Barry is correct, these can be really good sounding guitars after a proper conversion. Someone went through a lot of effort to end up with a crappy result.

Re: Gibson LG-0 bridge

That sure appears to be a Rosewood bridge but as Barry mentions, the White lines visible in the pin holes are odd. Can you see any evidence of an overlay on the sides of the bridge? It is surely modified and I suspect started it's life as an adjustable bridge, explaining the heavy bolt hardware you ...

Re: Gibson LG-0 bridge

Gibson plastic bridges.jpg It seems extremely unlikely that a plastic bridge used on these guitars would crack along the bridge pin holes, the same way they do on wooden bridges. Typically, you find them pulling up and arching when the string balls find their way through the lousy Spruce bridge pla...

Re: Banjo Dowel Stick Angle Adjust?

I would suggest that you begin this project just getting it cleaned up and installing a new head on it. Don't worry for now about the neck angle and string it up with a new bridge for the current geometry. You can change this later if you are unhappy with the result. Mandolin scale length banjos can...

Re: Need bridge thickness for 76 Gibson J-45/50

Hi Carl, thanks for responding. I have gotten a clueless response from Gibson and have this question posed on 3 different forums. No one has come forward so far that can measure an actual Gibson J-45/50 bridge. The J-45/50 was a transitional model that absorbed the J-50, came out in 76. Gibson has d...

Re: Need bridge thickness for 76 Gibson J-45/50

Thanks for the comments Bryan. This is one of my own projects, not client repair work and I am in no particular hurry to get it done. You are correct that the geometry, getting it back to where it should be, will drive my decision making. It absolutely will need the neck re-set and I'm sure the reas...

Re: Need bridge thickness for 76 Gibson J-45/50

I sent an inquiry to Gibson and received their response this morning. "Unfortunately, we have no ’76 models available to take bridge measurements from and we have no archived data available for the dimensions of bridges used back in 1976" Well, no help there... Hoping someone has one of these instru...

Need bridge thickness for 76 Gibson J-45/50

I have acquired a 76 Gibson J-45/50 that I suspect has had the bridge thinned to get the action lower on a guitar that needs a neck re-set. I am hoping someone has access to one and can provide an unmolested bridge thickness.

Re: Regluing tail block

The work can be done through the sound hole. However, if the binding is already off or loose and there is damage to the adjacent lining, there may be an advantage to pulling the binding back to address those issues. I put strips off acrylic mirror cut to fit through the sound hole and a light, so I ...

Re: Restoration of a 1931 Martin 00-17

Yeah Chuck but I have to draw a line somewhere or I will end up replacing the whole guitar. The handle broke on my fathers hammer, so I replaced it. Later, I broke the claw end off of my fathers hammer, so I replaced it. Is it still my fathers hammer? Yep, if you go too far you will end up with a n...
