I really like the Woodcraft veneer stuff. Especially the skateboard stock.

Intonation: Ive never seen this

I'm restoring an old parlor guitar. I have just discovered that it plays 20 cents sharp. Thats not in and of itself a mystery, usually. This guitar however has exactly the same distance from the nut to the 12th fret, and from the 12th fret to the "saddle" which is now a small shim under the two E strings both are 12 3/32"...with room in front of the bridge pins to finesse the location of the saddle slot, which I have not routed yet) I s…

1966 Gretsch Country Gentleman binding replacement.

Good afternoon all. I have started the process of removing all the binding from the old Country Gentleman and it's going well. I did discover after removing the strings that the neck is pretty loose and moves around quite a bit (no surprises there). I removed the black plug on the back side of the body then removed the large regular (slot) screw that holds the neck in place. I thought the neck would just slide out considering how loose…

Gagliano 701 Jumbo Neck Joint

A Gagliano Jumbo probably made by Kay in the 1950's. It looks like this had a previous neck reset based on the shims and some sloppy chisel work. I removed the 14th and 15th frets because I had read that these might have a straight tenon. I didn't need to drill any holes for heat, as the spruce shims both split in half after the fretboard extension was released. The dovetail is about 11mm long, the pocket is 14mm deep, and the 15th fret…

So it's a traditional dovetail joint then? Hard to tell if there is a taper from photos. The Galiano-labeled guitars made by the Italian luthiers working in NYC in the first half of the 20th century…

Seagull Acoustic Neck Reset...

Hey everyone, I wanted to do a bit of a follow up on a repair I'm doing. A customer brought in a Seagull acoustic guitar that had been dropped, causing the heel block to separate. I managed to get that glued back together with pleasing results, however I did need to take the neck off by removing the two bolts which thread into the heel block, and unglued the fretboard extension. All went well here, although I'm left with a situation whe…

Repairing braces that do not close against soundboard

Hello Friends, I've had a vintage Epiphone acoustic stored at the shop for almost two years and it's about time to wrap it up. That never happens, LOL. It has a few loose braces, which is a repair I've done in the past. The problem with this one is that no matter how I jack up the loose braces from the inside, some parts of some braces simply do not move enough to come in contact with the soundboard. This is happening in a couple…

Warped x-brace on Gibson L-3

I watched the Guild F-20 video (https://dev2.loothgroup.com/groups/repair-and-restoration/forum/topic/cracker-x-braces-on-guild-f20/#post-60310) with great interest since I've been working on a Gibson L-3 with a similar problem. A little back story - The original repair request was to address a small pickguard crack on the sound hole side. After peeking inside, I saw 5 loose brace ends on the treble side. Still a pretty standard repair…

New Gibson L-00 retro with whimpy bridge

Hi Folks. I have a new Gibson L-00 retro on the bench. It came in because the saddle had pulled forward and was extremely loose in the slot. the saddle was a narrow affair measuring out at 3/32. It had buzzing issues as well because saddle was low and neck angle is actually high (straight edge is 5/32 above bridge). Previous looth tried to correct by shimming saddle but recommended me for bridge work. I re-slotted the saddle slot wi…

Fingerboard extension gap - new build

I'm nearing the end of my first build. I have about 1 mm gap above the top at the end of the fingerboard extension. I've read and seen some guidance to clamp that down while gluing the extension. Others seem to build in a wedge-shaped shim - although it seems that is mostly done with neck resets and not new builds. A straight edge on the frets is just slightly above the top of the bridge so I think my neck angle is good. What are your t…

Brad, congrats on nearing the end. It's a good practice to put a straight edge on the part of the top under the FB extension to verify that the top is flat in the fingerboard plane. I learned from R…

Getting perfectly flat without a jointer

Hello -- I am trying to joint a Tele-style mahogany neck blank. I have a Metabo planer in good condition, but no jointer. I secured the c. 40 mm thick blank to a flat plywood sled and shimmed it well. It's hot-glued in place, and absolutely no rocking from any corner or edge. But as I plane it down, I still have about 1 mm difference from one end of the blank to the other when I put a straightedge on the surface (see photo, with backlig…

Neck Shim spreadsheet

First time here on the forums, not sure how often I'll check in, but thought this the best place to post it. Was playing with an idea proposed by Buck Van Laarhoven on a parametric model for bolt-on neck shims, and found the formulas I wrote up translated easily to Taylor and conventional acoustic neck joints so decided to add boxes for those as well. I'm not well versed in Google Sheets, but couldn't see a way to upload the file direct…

3D Printed Neck Shims?

I have searched the forums and was not able to find any discussion about 3D printing neck shims. This made me wonder if with the proper density of infill, may be a viable option. Or is this just taboo? appreciate hearing others thoughts on this

About Communicating with Customers

So, I’m a month and a half into this repair business and so far so good. I think I’ve got more than adequate skills to handle the physical, customers have been coming in and balancing a relationship with starting a new business is going well. But…… The scariest thing is how to handle customers and the things they love. So far, I’ve been able to test the waters on repairing fairly inexpensive, not too attached to instruments, easing my wa…

Set-neck pocket and angle questions

Hi Everyone, I’m working through building my first set neck electric, an LP Jr. I had some build questions… - if you’ve built these Gibson style set necks before, did you cut the neck pocket straight and angle the heel of the neck? Or did you cut the pocket at the angle and keep the bottom of the heel straight? I’m attempting to cut the pocket at an angle, and it isn’t the easiest thing to do, I’m finding out. First, I’ve had some moveme…

Hi Joe, I would recommend putting the taper in the neck pocket, not the neck. Maybe you need thinner shims to solve your router depth issue. I would glue the fingerboard onto the neck and have that as…

Jester W160 neck joint

This is an early 80's Jester. The only identification is the label inside which appears to show the model number as ACW160, though I've only seen reference to model W160 online. There is scant information about Jester guitars online, and some of it seems inconsistent. This was most likely made in either Holland or Romania. Online information indicated that this would have a dowelled neck joint, but it clearly doesn't. This was a very di…

Bridge Too Low?

Finishing up a new cutaway acoustic. I thought I had it right before finishing, but now that the finish is done and the neck is bolted on, a straight edge on the frets is 3/32" over the top of the bridge. Can I work with that, or do I need to either add a shim under the bridge, or just cut a new bridge? Any advice would be greatly appreciated... Paul in Chicago

You can work with that. Under string tension the neck will come up a bit anyways. I used to build with the straightedge just grazing the top of the bridge like a lot of folks show you to do, but talle…
