Re: October, yes October tutes

OK. I am glad that I am not the only one who needs to clean up glue squeeze-out! I did a vacuum clamping of a bridge tonight, with HHG. After 12 minutes of clamping I took the vacuum off and cleaned up the glue with hot water, soft cloth and a pointy stick. It took about a minute as the squeeze-out ...

Re: 8 string baritone

Lovely instrument Jim. I built an 8 string also and love the 12-string lite feel and sound. Tell us about the bracing that you used. Did you make it any heavier for the extra couple of strings? I also like the partial rosette style. Did you use CNC (like Allen does) or is that some fancy work by han...

Re: Bridge gluing

You need to be fussing about with clamps and checking that it is staying in position - so cleaning out the holes is not going to be a priority at the time. Do it like Martin said and clean that later (pin hole reamer is my recommendation). You have an issue with some of the top ply coming off outsid...

Re: How secure is binding?

Yep - bindings falling off are not likely to be a problem, and can be pretty easily fixed. But the kind of surgery you are contemplating is likely to be ugly, and not disguisable. You can reshape a solid body electric as much as you like. It is just a lump of wood with some electrical equipment bolt...

Re: Multiscale bridges

Thinking about this a bit more I realized another reason why Lowden probably do that shape for their multiscale bridge - it keeps the bridge wings in the usual location so that there is no change in the relationship of the bridge wings to the underlying braces. Martin showed us in his build that he ...

Re: Multiscale bridges

Good topic Dave. I am working through a multiscate build at the moment and wrestling with the same problem. Our human brains are very attuned to the appearance of symmetry, and our notions of beauty versus "doesn't look right" are really hung up on this attribute. For example, when humans rank the s...

It looks rather like a CF fabric, and so I would be hoping that epoxy would work well with it.

And I am about to rebuild a guitar body made with HPL...

Re: Louro Faia for binding .. a complete failure

Well those pieces just didn't want to bend! You gave it your best shot. It's lucky that you have a plan B (right??). I am sure it will all be OK in the end. You just need some other bindings.

I have got that Scheppach model that you are already famiiar with. Not great, but not bad, and enough for my modest needs. It is hard to imagine that the "Powertec" one is any better - but I can't tell you for sure.

Re: Ukulele Need Of TLC

For $8 I probably would have grabbed it too. For the fingerboard, start with a rub down using superfine (0000) steel wool over the frets and the timber. Then a good vacuum, followed by some oil. I would be surprised if you need superglue for the FB. I can't see the cracks - but maybe I am missing so...

OK, that looks straight forward enough. Do you drill into a solid blank and then route out the middle, or route before you drill?

Lovely work Trent. Lots of nice individual touches. Well done with the 18 hole bridge. It creates such a clean look and good function. When I tried it once I got a good functional outcome, but mine doesn't bear close inspection of the regularity of the hole placement. Did you develop any good tricks...

Re: 8 String bocote falcate braced nylon string crossover guitar

I am impressed too. I just did a re-top job on one of my previous builds and my method was much less refined, and took way more effort than that approach.

Looks like you are back on track with this creation John.

Re: lamitated armrest bevel - an idea

Yes, that looks much better than the exposed laminations. I think you hve achieved a good result. We can all drive ourselves crazy noticing the tiny imperfections, but most people won't see them at all. The repeating of the padauk colour in the bevel and in the rosette looks great.
