Splines: When are they necessary?

Question about splines: At what point are they necessary? My question is primarily regarding the crack to the left between the bridge and the sound hole as well as the crack at the upper bout that runs along the fingerboard extension. I have already glued them both and used the TJ cleats that run the full length of the cracks. I have already splined the lower bout crack that runs from the bridge to the binding as it was super gappy and d…

Sadowsky bass help needed please 🙏

Sadowsky use unique control plate screws which are much smaller than common plate screws. I believe the ones they use are: #3 × 3/8" Phillips Pan(domed) Head Black Oxide csk self tapping Sheet Metal Screw Type AB thread. Being in the UK, these are really hard to find, pretty much don’t exist here, so can anyone please help me or point me in the direction of a supplier? I’ve contacted Sadowsky direct with no response and also many of my main…

Crazy electrical issue

So today, while restringing a guitar, one of my techs dropped a .012 e string that slid down the wall and landed on a plug that was just slightly loose from the outlet. It landed just right and made a huge spark. No lesson to be learned here but a crazy thing to happen! We are changing our name to Sparky’s Guitar Service. 😬

Local Thrift Shop Find: Gibson Ivory Top A3 Mandolin

A customer brought in a Gibson ivory top A3 mandolin. It's in good shape and has all the parts. He found it at the local thrift store here in Bishop. He wants it mechanically sound. Here are the problems: 1) Everything that comes into the shop has a shrinkage component and the effects of course very from instrument to instrument. This instrument is no exception and the results of that shrinkage, in this case, are severe. The top, ba…

Bending purfling- need advice

First time making purfling to match a repair. Problem: couldn’t get it to bend without delaminating and cracking. Veneer is 6 plies using 4 of SMs 0.023” and 2 maple at 0.025” cut to 1 1?2 inches wide. Glue up with Titebond Veneer glue, final stack at 0.140” thick. Let it dry 2 days, cut a few 0.090” strips, then used some super soft just at the waist and despite going very slowly the strip skewed, delaminated and started to break plies. W…

I've never used titebond veneer glue before. But when I make purfling, I use a polyurethane glue, like gorilla glue (activated by moisture), so I can use steam to bend the purfling to the shape I need…

Drum Sanding Tops and Backs - When and which sander?

So it seems that a drum sander would be very handy for many parts of a "build from scratch". There are a few out there that cost under $3000.00 that can handle wood up to 4" thick and are wide enough to sand a back or top after the halves have been joined.

DIY silicone blanket heater

Thought fellow looths might enjoy this geekery. I've often wished for custom size heating blankets, but didn't even try uploading the file to get a quote from some of the major manufacturers. I was looking to spend countless hours of my life on something and save a hundred bucks. So I did some research, a little bit of head scratching, a slight bit of math reckoning, and made this '70s Martin bridge plate remover. Pretty slick, nice…

Suggest an alternative to concave fret file

(for background context, I'm probably in the dozens of fret jobs so far, and no I don't let frets leave my house like this) When I got started getting interested in building guitars, I got the StewMac bundle of fret files/book, which comes with the concave toothed file. Over time, I ended up getting both the Narrow/Medium and Wide/Jumbo files. I don't do it often, but occasionally I do something like shown in the picture, where I'm clearl…

Holy cow! That’s a change!

Whadda shock when I signed onto the website this morning! Looks great, Ian! And responsive, too. The downside of all these improvements? I’ll spend far too much time on the computer rather than working in the shop. Great work and congrats to all of you who make the LoothGroup a reality. (But Ian still hates guitars - me too..) Rick

1965 Stella

This guitar appears to have been assembled with urea formaldehyde glue, which is insoluble in water and doesn’t melt at any reasonable temperature. It is definitely not hide glue or resorcinol.The neck pocket is not under a fret slot. Luckily, very little glue was used to assemble the neck and it was all on the cheeks of the tenon and the neck came off rather easily using a combination of the StewMac heat rod and foam cutters, with smal…

Incoherence between CAD and test-piece

Good morning everyone, I was taking some measurement on production necks with scarf-joint (13° headstock angle) to add some machining process with the cnc. I so recreated the standard neck blank feature (100mm wide and 20mm thick), then drawed the 13° angle. Everything correspond the to the real piace but two measurement: the startingcut behind the break angle is ''off'' by 20mm +/- as well as the cut on the bottom, still off by 20mm…

Is it possible that the angle of the scarf joint is different from the angle of the headstock on the real piece? Could be a manufacturing quirk
