Re: cutaway at neck body join

I do actually contour my neck block to match the taper and even swoop a little into the cutaway (by sanding it a little against a form). But it never seems to line up perfectly anyway :( so I live with a little mismatch and finesse the fingerboard and extension a little. The results are usually fine...

Re: arch top how to align neck,neck block and end block

I’m not 100% sure I understand your question. The head and tail blocks don’t necessarily have to be in any tight alignment. You generally cut your neck dovetail after the box is closed up. Assuming you’ve used two pieces of wood for your top, the seam will define your center line. The mortise would ...

Re: Distributed Mode loudspeakers - Have there been any discussions?

There is a guy on YouTube that did an exhaustive test of different materials and exciter/dampener placement. It is impossible to know what they sound like from a YouTube video, but the whole thing was less than $50. Worth the experiment. A crossover and a subwoofer would fix any low end issues. Ther...

Re: Tap tones for archtop top-plate, help needed

As you must already know, the use of frequency histograms to tune a top was completely unknown to all the previous master builders. From Benedetto to D'Angelico, none ever saw a histogram. To the best of my knowledge, the principal architect of using a histogram to tune a top is Trevor Gore. His boo...

Re: Retail CA - which is best?

The problem I have with CA is that I open a bottle, use it, close it tightly, set it aside for a month or so until next use, open it again, throw it out, open a new bottle... So I find myself using the single use bottles and the GlueBoost Accelerator. Is the Locktite better (or Satellite City, or Gl...

Re: Need some advice on fingerstyle guitars

I've played without a pick for thirty years. I do think some guitars are better suited tonally. Generally I avoid guitars with boomy lows and sparkling highs and look for something more balanced. As a result I rarely pick up a dread or jumbo. But you can't really make anything more that vague genera...

Re: Charlie Christian pickup with coil tap/

I believe CC pickups are single coil, so do you mean a tap to split the winding? So like after 5,000 windings you insert a switch and then do 5,000 more windings? I've never heard of that, but the best CC pickups I've ever used are from Pete Biltoff at Vintage Vibe Guitars. He sends them to you with...

Re: Neck Mortise and Tenon Jig ?

You can buy plans from Robbie O'Brien to make the exact same one as LMI sells. It is not too hard to build, but I understand that some people love building jigs and others not so much. Of course you can buy it from LMI for $200. While that is an outrage for a few sheets of MDF and some bolts it's a ...

Re: Neck geometry question for semi?

Thank you Freeman. 1/8” of arch is surprisingly little. On a couple of plans I found online, 1/2” seems more common. In any case, I have my answer. All the dimensions that make up the neck geometry are tweaked and not standard to Gibson arch top guitars despite some visual similarity. I’ve spent som...

Re: Neck geometry question for semi?

Thanks Bill. That was helpful. I've cross reference a couple of plans to try to get all the dimensions. Looking carefully I see that all the dimensions are cheated to make up for the missing .5". The arch rises above the rims .5, instead of .75, giving you half of the difference. The other half is i...

Re: Neck geometry question for semi?

Well according to one Gibson fan site the ES 335 (in fact the entire thinline ES line) specs 4° to the body. According to Stew Mac, and ABR-1 bridge is roughly half an inch thick and has roughly half an inch of travel. If both are true, the only thing left that can give is the height of the arch. Is...

Neck geometry question for semi?

I am interested in making for myself a semi- hollow archtop guitar guitar. Unfortunately I don't have one myself to study, so I'm having some issues understanding the neck geometry. On a traditional full hollow archtop, like an L5, the neck comes to the body at 4-5° and is elevated off the body abou...

Re: CAD file for archtop guitar plates

The usual path, if you are not already an industrial designer, is to hire someone who is and pay them to develop a CAD file to your specs. The probe generally is to help you measure existing plates to get those specs. People don’t generally rely on probes to generate a finalized surface. There was a...

Re: ES335 style center block questions

Thank you Barry. I'm definitely leaning toward doing the center block in three pieces even if I have the capacity to do it in one. I can't get over the idea of a difficult glue up. It seems much easier to glue the center to the plates first, create a flat mating surface, and then glue that to a flat...
