Re: Quality Machine heads

That's bad news on the Schaller M6's....they're my favourite tuners. You might have to bite the bullet and go with Waverly's....I've never been disappointed with their product.

Re: Classical Build (s) - Hopefully falcate!

I usually have the mike over the sound hole (about 2-300mm away from same) and tap on the bridge area. I think if you do same you'll get a nice sharper T(1,1)1 peak.

Re: Classical Build (s) - Hopefully falcate!

I need to look at that tutorial Dave M was talking about and redo the tests. They did seem a lot clearer this time though. I think in the past I haven't been waiting long enough for the buffers to fill. All the main peaks appear on the first tap. Thanks for the help. It's much appreciated. I can se...

Re: Classical Build (s) - Hopefully falcate!

Richard are you tap testing with the sound hole blocked? I cant see any T(1,1)1 peak on that first plot.
I'd re-tap with sound hole open and if no change in T(1,1)2 then I would consider not doing any thinning of top perimeter.

Re: Classical Build (s) - Hopefully falcate!

I only weigh the plates prior to initial tap testing to derive density values. I tap at all phases of a build. Tap testing with a mic and software is a great system but at the same time I like keeping a running handle on how the top sounds to the ear through the build process. Does anyone else weigh...

Re: Classical Build (s) - Hopefully falcate!

I usually do a tap test on my braced up tops and backs more to get a feel for the sound of same rather than to gather peak data....the shape of the plates has changed since the initial free plate tap testing. One thing I do is tap test after Ive cut out the back and front on the band saw so I can ge...

Question...when i was putting the CF tow down on curves say for secondary braces it doesnt want to bend in plane and "sits up" . Under the brace this gets squashed but it will be visible on top.

I might be over thinking this... but at a guess like metals, different woods would react differently to temperature and a lesser degree (Given the body is painted) humidity. Wood is porous while metal isn't. Thermal conductivity is also very different for the two materials....it's the reason the ne...

After a few "incidents" in the past the forum was set up so only admins and mods can edit or delete posts. Since then the admins have only taken this option when a post is obvious spam or we are requested to do so by the person putting up the post.

Re: Classical Build (s) - Hopefully falcate!

Brace height will affect overall stiffness more than width. I haven't bothered to do any calculations to work out brace height. I run with Trevor's figures on his plans. I actually measure stiffness of the bracing stock before making up braces and if its a bit low side I increase the height by a few...

Re: Classical Build (s) - Hopefully falcate!

Yes....I include this brace to reinforce the top joint. On my non falcate builds I'd usually put a small patch or two along the seam in same location.

Re: Classical Build (s) - Hopefully falcate!

None of my falcate builds have been strictly to the plans in Trevors books. The last build was a multiscale so I had to work out brace layout according to the guidelines in Trevor's books. The braces were also assymetrical so making them was twice as much work as for a conventionally scaled instrume...
