Re: Selmac Grand Bouche

Yes, I've had a go at a few Selmeroids! They are not at all like x braced guitars to build or understand. The ladder bracing favours long dipole and tripole modes and suppresses the cross dipole and tripole for a start. The neck angle is a critical factor so that it gives around 18-19mm bridge heigh...

Re: Selmac Grand Bouche

The original Selmer Maccaferri design featured the large soundhole, ie "Grande Bouche" along with an extra internal soundbox and reflector. This had the effect of having two air modes, one for each soundbox. However the internal soundboxes often rattled loose, so the simple solution was to remove th...

Re: Semihollow fifteen inch

An exquisite instrument indeed! Re the router/trimmer, my mistake, to clarify, the trimmer has a plunge router base attachment available which is very good. As I said, I got the base from England a few years ago.Cheers Ross

Re: Hello from Canada

Well done Dave! I love the OM design, personally. The dreadnought guitars are over represented, although bassier but not as even in tone to my style of playing...you mentioned building in winter. Either way, the relative humidity is the issue really. Learn about humidity management. Welcome to the b...

Re: Guitar top and back radius position

Check out the way the old school Spanish construction methods work and are executed. My findings are to place the back in such a way that someone holding the instrument with a strap doesn't choke the lower bout with their body. There are high end US builders, eg Linda Mansell who has made instrument...

Re: Semihollow fifteen inch

Looks great, Rod. I notice you have the best plunge router on the market in my opinion, as I use the same. The plunge router base is excellent and opens up lots of other possibilities, is stable too. Great for template routing and more stable for dovetail joints with template followers, which are ch...

Re: Back in Business

Thanks Leigh! I recently explored the possibilities in the North East where I live, Mirrortone out of Albury was more costly than the Durobond nitro including freight to my home, which was almost as much as you would have paid. I also explored the Mirrortone health hazards and felt that the Nitro an...

Re: Thickness Gauge

I made an aluminium thickness guage, but have concluded that a marine ply structure is way superior...the aluminium is extremely temperature sensitive and the guage jaws move with temperature, even from the body heat of hand contact. I would surmise that the Chinese aluminium thickness guages also m...

Re: What difference lacquer makes to sound

I use Durobond nitro as mentioned in "The Books" by Trevor and Gerard. The idea of using the sanding sealer doesn't rock my boat because the sealers are a type of vinyl base and seem to me like they deaden the sound. So I apply the nitro straight to the soundboard, or perhaps with a layer of shellac...

Re: Go Bar Rubber feet

From rubber feet to the plane truth in this thread...rubber feet are available from Clark Rubber if you can find a shop! Bunnings also. The white ones don't leave a black smudge, but given time they go hard and slip off the work rather than grip. Martin's (Trevor Gore's) cauls are a good solution......
