The Nerd pickup winder

Hi guys, here’s something I’ve been working on: a fully automated, programmable pickup winder. The software is still in alpha testing and there’s still a lot to design, but this is what it looks like so far! Images

Spot spraying versus refinish whole neck?

Hey guys, Up until now I've always tried to blend any repairs into the surrounding area when it comes to finishing and avoid refinishing as much as possible. However, im yet to be fully satisfied with the results or hit the elusive "invisible repair" So my question is, for this headstock fix in the image, would you simplly refinish over the splines or consider refinishing the whole neck to avoid the blending battle? For what its worth, its…

+1000 on Ian's comments. To add to that - I tend to avoid blending as much as possible. I underquote and takes "3 forever's" worth of effort to get a result that I AM HAPPY with. Now I quote a price f…

Ken Parker finishing with the Bridge on

Just wondering, anyone doing Ken Parker finishing on an acoustic with the bridge glued on? I've been using the finish for a while but I'd like to start glueing the bridge on before I finish so I can acoustic test everything in its final state. I can't see a reason why I couldn't wipe the epoxy and oil up into the bridge joint and then remove it by rubbing but I was wondering if anyone has done it already. It would mean finishing the…

Which finish are you talking about ? It sound's like it's hand applied.

Guitar frequency testing in the white.

In Michael Baskin's on-line video, he uses a frequency test of a guitar in the white to determine whether to thin the lower bout before finishing. The guitar in the video has a bridge attached. I'm wondering if this is the final bridge or something temporary. If the latter, how do the results compare to the final frequency analysis? I've used a bolt-on bridge to do the same, but don't have enough data points to draw a firm conclusion…

I would probably blue tape/super glue the bridge in place vs bolts which would change the weight somewhat radically.

Testing Mandolin Top Wood Billets

For my current mandolin build, I set out to answer 2 questions: 1. Whether to use physical deflection or frequency analysis to measure stiffness, and 2. How well can I measure wood quality in rough sawn form? (T. Gore says it needs to be planed smooth and rectangular for frequency analysis.) I have 4 different topwood species available for my current build: California Sitka, Englemann, Lutz, and Coastal Redwood. The billets range from 37…

Hello Neil, I also measure wood properties when I build mandolins and what you did is very similar to what I have tried, so I'd like to share some thoughts and comments. From my engineer point of view,…

Side bending - actual problem or isolated freak out?

Hello All! My first post and I'm very happy to be here and share the highs and lows of this pony ride. After years of bending sides on a hot pipe or bending machines belonging to 'other people', I finally built myself a bending machine. Functionally it is great, but the result on some test material was far from great. See pictures attached. What you see here is a doug fir 'test side' that certainly came out guitar shaped, but oh my, what…

How to "Fix" Rosewood Bridge Dyed Black?

I dyed an East Indian Rosewood bridge black to match the Blackwood fretboard before gluing it on*. The bridge is now glued to the top. What are some ways to "fix" that dye into the wood. I'm not crazy about TruOil - up to 40% mystery oil..... *I did a sample on rosewood with 4 different "dyes" and they were all stable, would not rub off with paper towel, naptha or mineral spirt. I went with the TransTInt. I did not however test with…

@Chris Frederick Guitar Recovery LLC I tried some "Lemon Oil" over the already dyed bridge and it actually set the color, thanks for sharing that. I don't know why that worked, but it did. I'll fini…

1970 d-18 patch

Hey! I have been working on repairing a d-18 that had a large hole in the side. I glued in a backer, cleaned up the edges and after a few attempts got a patch glued in and leveled. I have been testing finish on some scrap but am getting lost in the woods. In my tests I am doing most of the color in the grain fill. Does anyone have tips on how to start touching this up? Thanks!

I did a repair on this Martin and had to sand the entire side and refinish. I found this was the best way for me to get a good result. I could have tried spot finishing but I'm sure I wouldn't have b…
