Re: Louro Faia for binding .. a complete failure

And of course it isn't just the bindings it's the side as well. But we persist because we like the shape and because we love the cutaway, even - actually - especially on classicals. I haven't been quite as sharp on this one but I do like it.

Yes Trevor has caused a fair bit of grief pretty much round the world with that cutaway!

Re: Lutz/Blackheart Sass Hybrid Nylon, venetian cutawy & arm bevel

Trent great detailing. I imagine that scooping of the heel is to further improve access to the upper frets...?

I'm looking with envy at that armrest. I left my last classical with too sharp a corner and end up with a great crease in my forearm!

Re: How big a drumsander?

I have the Jet as with Martin.I seem to have been luckier than him (and some other builders) because it has worked well with no real problems in several years. The width is a bit limited, it will only just cope with Trevor's steel string design. Haven't tried doing a pass with part of the timber sti...

Pore fill Bindings

Do people pore fill bindings? I have a maple back & sides steel string on the bench and am pore filling the mahogany neck, the rosewood headstock veneer and the relatively broad rosewood tail graft, all of which have pretty obvious pores. The bindings are the usual around 6 mm deep by 2 mm width and...

Re: Rosette Router Jig

Thanks for that Trevor. It is maybe time to step up from the simple version you described in the book.

I have to say how much better I found the DeWalt trimmer compared to the well known UK make that I have been using.

Thanks that was fascinating. It speaks of many years of acquiring the skills. I can barely believe that a single stroke with a plane could produce those thin veneers of marquetry intact.

Re: Neck Thickness

Thanks for the reassurance. It was just a moment of panic seeing this slender piece of timber and thinking of all the stress it would be carrying.

Re: Neck Thickness

I didn't explain too well... this is the neck without fingerboard. I have a minimum of around 6 mm to the truss rod groove so that should be OK. I take the comments on neck feel but my real concern is whether it is going to be strong enough. I guess I could leave the fretboard at 6.5 to add a bit, b...

Neck Thickness

I have inadvertently taken my neck down to 15.4 mm around the 1st fret. It will get a bit thinner at the zero fret position. This a Steel string done in Mahagany. Is this too thin? Do I have to consider glueing on a veneer or is this going to work? It really feels very thin to me. I have already put...

Re: Further J45 questions

Well I wish I'd read this a few days ago - assuming it had been written. I think that must have been what happened to me. My bindings came out less tall than the should have been.

Re: Routing bindings/purflings

Thanks Steve. It is entirely based on G&G's design with a bit of development looking at what others have done. (Oh and any reference to coal mining pit gear will earn a slap!)

Re: Routing bindings/purflings

Well it is not a panacea. Routers whiring away are, at least for me, always a bit of a worry. However with this setup, using only spruce and maple back and sides I haven’t had any chip out. What I do get, doing the top corner is fuzz. Ie fibres of the spruce that have not been cleanly cut. I always ...

I do as Wayne. It took a couple of iterations to get the router holding tower right. I use a counterweight to reduce the load the router puts on the guitar top.

Re: 12 fret BRW small body

That must have been very interesting; to see how your design has stood up to serious playing over a significant time period. I imagine it was falcate braced with CF so the top probably didn't move much but I wonder if it continued to compress a little? Did the saddle positions need lengthening at al...

Re: 8 String bocote falcate braced nylon string crossover guitar

As always nice looking work John. As always I am interested in the falcate bracing. You presumably beefed it up a bit for the extra strings so I wonder what height you ended up with? I wonder if you have had time yet to look at resonant frequencies, and perhaps particularly with this one, the bridge...

Forgive me if this is too basic a question but I am trying to use abalone for a rosette for the first time.
