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.

Only one way to find out!

PS: the top bridge looks nicer.

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.

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...

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.

If the sides aren't tapered...then it's a banjo....and we don't wanna be buildin' banjas do we???

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...

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. Any way of getting around this? (Too late for this build but ill probably go on to the next one soon) It...

+1 for the opportunist! We are the lucky ones with a workshop (well sorry Martin!) and an intense desire to create, so lockdown is not really so bad - I refuse to call it an opportunity but we can certainly find plenty to do. Its not all bad. I'm currently sleeping in the workshop...it's kind of ni...

Jeremy might be in contact with Pete.

Can anyone point me in the direction of some figured Brigalow for fretboards, I thought Pete McCurley might be a possibility, but he does not seem very contactable?

Thanks

Is the bridge on yet? If it isn't then make sure you're allowing for effect bridge will have on main top frequency.

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...

Wow I'm the slowest builder out there!

Sorry but Im wearing that crown right now mate. 2 years since I packed up my workshop for a new house build

Some Mac laptops and tablets have inbuilt mics that work well enough (if you can get VA to work on a Mac) but none of the PC laptops I've ever used has worked well using just its inbuilt mic. I ran VA on my Macbook Air via Windows running on top of Parallels. It works ok but moving data files in an...

No bridge patch for a classical Richard. There's piles of CF in the Gore style classical bridge.

Stay safe Steve. If it's any consolation...quite a number of studies have concluded that sales of musical instruments exhibit a significant increase during times of crisis. Once this is all over yo'ure going to have a flood of repair jobs coming in

Looks like you got things working

As far as I know you can post pics regardless of number of posts. What error message are you getting?

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.

Allen McFarlane does interrupted rosettes in his ukes....

I have some ideas for an interrupted rosette - hence the need for a more accurate router jig. Once again, thanks

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...

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.

Forgot to ask...did you guys put that little diagonal brace that is on the plans near the bottom of the soundboard on your classicals???

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...
