Re: Guitar bridge as a brace

I borrowed the Somoygi book at one stage and he talked about the amount of the bridge touching the braces and the coupling...but now I cant remember what was actually there, but at the time it got me thinking back then about the bridge activating the braces...I think if the outside braces didn't cou...

Re: Brisbane humidity

I'll make these comments from what I know about RH. The most common dehumidifiers work like a refrigerator and use a similar amount of power, at the same time they are also heaters. So add the refrigerator power consumption to the heater power consumption and you have the total power consumption of ...

Re: Guitar bridge as a brace

Thanks for your comments John. One thing I forgot to include in my speculation is that the bridge has quite a lot to do with the impedance/admittance of the string energy into the soundboard and the amount of energy reflected back into the strings to create sustain. This balance could possibly be ex...

Guitar bridge as a brace

On standard X braced guitars, as an example, the bridge consists of a bridge plate, a bridge, and sandwiched in between both is a section of soundboard defined by the area of the bridge. The bridge acts as a brace between the two X braces south of the X and the amount of bridge that contacts these t...

Re: Side sanding dish motor & side bender??

I use a hand plane to get the sides pretty right, then finish with a sanding dish by hand. I first use a pencil in a block of wood, sit the guitar in the sanding dish, run the pencil around the outside of the sides, then plane to that line. Then I install the bindings, sit in the dish again and fine...

Re: Side sanding dish motor & side bender??

Try bending the bindings as a side then use a block of wood, held with double sided tape to your bandsaw, with the top of the block of wood rounded over and the blade cut into the block for supporting the curved liners, then slice them off. I have attached a high fence made from 1/4 inch steel plate...

I’m nearly two metres tall, so a dreadnought looks a bit like a ukulele in my hands! You gotta look good!

I have never had a problem with orange peeling. I have always warmed my thinned lacquer, in the paint pot, in tepid water prior to spraying. As long as the nitro can offgas effectively at ambient temperature. Too thick a coat and it case hardens but is still soft underneath, so drying times increase...

I'm a nitro man! I have tried the sanding sealer from Durobond as I use their nitro. It seems too vinyly for my liking (there's a new word!) I sometimes use either an epoxy fill or plaster of paris which sands off easily, along with a stain which matches to wood. I have also used shellac and hide gl...

As an aside I can tell you that I faced a very similar problem recently. I made a falcate braced 7-string multiscale fan-fret thing. The placement of the braces and the bridge was tricky. I thought I had worked it all out perfectly, got the bridge and saddle in the right locations, and fitted the p...
