Hi All,
I just wanted to give an update to those who had deposits in with me.
I've just now gotten back into my house. It had to be remediated for smoke damage and have the windows replaced. ...
Hi All, Sorry for being unresponsive. I have a health condition that required that I take a full-time job (non-mandolin related) in order to get health insurance. Not my ideal scenario, but,...
Besides damping (heat/friction, and sound radiation), acoustic impedance plays a major role in sustain. As the pressure wave moves between various materials a certain amount of energy will move...
For my kits the riser block is glued on first and then the the neck joint cut into the riser block and the rim. The joint just barely has enough room for glue, so there wouldn't likely be any creep,...
Hi Brick, You should glue the fingerboard extension on first, then level it and the riser block flush with the neck prior to gluing the fingerboard on. To level them down I use a long flat piece of...
Website is cleaned up and safe to visit again.
Hi all, my website currently seems to have a malware infection. I've hired someone to clean it up. But, you may want to avoid the above links to my kits. Sorry, should be cleaned up soon.
Hi All, I'm still building both kits and finished instruments. My waitlist is always fairly long for both, so I don't spend any time advertising, just stay busy building.
Hi All,
A quick update on Arches Kits.
I had some family related medical issues that brought the Arches kit production down significantly over the last year, and so I have a rather long wait...
Most towns, at least in the west, have a creek or river (or two) named "Millcreek". Very common, makes me want to research the history of the mills that gave the creeks around me their name.
Hi Bill,
Hold your hand up as you would play chords, fingers are still in a radius, with pinky finger by far, lowest down. At least that is how they fall naturally for me. It's a natural thing,...
Hold you hand up to your face, palm facing. Bend your fingers down in a natural way. Your fingers will likely be in a radius, as opposed to being flat across and level with one another. Index and...
Hi All,
My motto is - "The more mandolins in the world the better!". So I offer kits to those with nothing but a desire to build and a kitchen table. I do hope to offer kits at a lower price...
On some modes, the sides actually carry the mode over to the back. I have also made my sides rather thin, around .085", but Gilchrist and older Gibson sides are more like .100-.120". Thinking of...
kkmm,
Prices aren't set yet, but, please use the "enquiry" form on my website to contact me and I'll give you more info.
Planning to provide kits as well. Check my website below.
Ok, yes, I am using "FFT" to refer to data obtained from a time domain signal transformed into frequency domain using an FFT. I should have used the term "spectrum", or FFT results, or frequency...
An FRF is more consistent and reproducible than an FFT because the input is also a factor in the FRF. Which means that you can bonk at different levels of force and come out with nearly the same FRF....
As I've said, I'm not trying to explain anything, only report that I've seen significant changes to the modes with changes in string tension. I've seen it many times with both microphone gathered...
How is it that a string's modes can change with tension where as a mandolin's body modes can't?
Like I said, in any event, I'll gather some more data and we can discuss.
Dave,
I'm not really sure what you mean when you infer that I'm interpreting my data wrong. I'm careful to take my measurements the same way, and, as you know, frequency response functions help...
I actually use an accelerometer and a small pcb force transducer hammer to gather frequency response functions. I'll post some data when I string up the next batch of mandolins. I also damp the...
Arigato,
I'm not sure what causes the effect I described, however, it can easily be tested as I've said. Try it and see. The forces that the string tension exerts throughout the mandolin affect...
Neck angle can affect the string's breakover angle at the bridge, which can affect the downward force on the top. The amount of downward force affects the modal frequencies of the instrument and...
I use system 3 clear coat with fumed silica. Works well for filling the grain in the "invisible way". But, is a mess. Been meaning to try fumed silica and shellac/fp method, vs shellac and pumice....
