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...

I don't have the books handy right now. With a steel string you generally run the cross brace (on a conv braced instrument) or secondary falcate brace under the bridge wing. On a falcate braced SS Trevor recommends that the inboard end of the tertiary brace overlaps the end of the bridge wing. Less ...

As drawn the secondaries run just under the transition section of the bridge. To get the bridges really light I end up with super thin wings, so they wont have much torsional stiffness. Is there a particular reason to not put them under the main part of the bridge?, other than spacing? Cheers If yo...

King Billy Pine bends like butter but check stiffness of the wood before using it for braces. I used KBP on my first falcate build and the stiffness of the braces ended up being too low and I ended up re-topping the guitar with spruce braces. The stiffness of KBP seems to be highly variable. If you'...

It's a job for a machine shop.....they can mount the blade so it's centred and then make the hole bigger. Sometimes the teeth will need a dress up if the blade is slightly off centre

Carbatec stock them: https://www.carbatec.com.au/blades/blade-bush

You can get adapters. Here's one from an American supplier: https://www.mcfeelys.com/saw-blade-arbo ... 13287.html

Just out of curiosity, why two disc sanders?

One for dark coloured woods and one for light coloured woods....or different grits?

You're going to do a brace replacement job with the top on? Good luck with that :) Have you considered how you're going to clamp up the new braces without damaging the finish on the top? All your clamps are going to have go in via the sound hole and there's only so many clamps you can jam through sa...

Thanks for the update Woltz. All looking good

You've got the top off? Some photos would be great as this is a job most of us will have to do at some stage. I reckon I've done around 8 re-tops so far. yes I thought for my No.10 build I wouldn't run into trouble like that, guess i just proved myself wrong! Ill post updates, just started removing ...

Laurence, it looks like you'll have plenty to keep you occupied during the Covic19 lockdown

My initial thoughts......the scalloped section in the middle of those tone bars might be a tad to long. I tend to make the scalloped and peaked segments more equidistant when I do scalloped braces.

Any thoughts from other members?

What's the top doing in front of the bridge?

When you say the bracing is forward shifted...you mean you've moved everything closer to the sound hole? It might just be the photo but gap between end of X brace/tone bares and sides looks a bit on the large side....but maybe that's just me. Does the start of the of bellying correlate with the scal...

Any pics of the underside of the top showing bracing?

I hear you Allen..I'm currently living in my garage with my wife and the cat while our new house gets built. Stay safe mate.

Stick up a list of the items Robert and Im sure you'll be able to offload them.

I bought Mr S's books but only had a quick skim through same before "The Books" came out. My working copies of G and G are well worn while Mr S's books are still sitting in their slip case on the shelf.
