OK so I fell for The sliding bluesy sounds that came from Sir White's Wiess. Being my own customer gives me freedom to develop a design of my own rather than copy a Wiess or Greenfield bros.

Things I need educated about are :
String spacing, is 8.5mm @ nut & 11 @ bridge about right?
Advantages/disadvantages of wider/narrower?
String height 9mm?
Issues to think about with Weiss style bridge ,I am clueless on this.

The stepped top will be either 3 piece board matched 1/2' red cedar or 2 piece 5/8 doug fir.
Arched, board matched Khaya back
book-matched sides from same board. 3 1/2" or so.
Have not decided on headstock or scroll yet.
Still playing with body shapes but may base on my last   dulcimer   http://mysit e.verizon.net/resre6zl/

Any help with string height, spacing, or bridge design will be welcome as will ideas, points to ponder and constructive criticisms.

     Thanks in advance

For some reason I can't get rid of the space in mysit e
it doesn't belong there.

Kirby,

Those string spacings are about what I used - I am probably nearer 12mm at the saddle. The saddle spacings are determined by how you play - it is more like a fingerstyle guitar and if you play with fingerpicks you need space for these too. The nut spacing needs to be enough for you to cleanly use the slide bar (whichever type you use) to fret both individual string notes and across the strings. You need enough room for the individual notes but not too wide that the bar won't fit across them all.

String height off the fretboard is around 9.5mm.

The bridge is like any other bridge in terms of the design priciples except for a couple of things:

    - you need it tall enough to give you 9.5mm action along the fretboard but still with saddle height as you would aim for on a steel string

    - the saddle has no compensation and is set at scale length across the entire length


I decided that I wanted a normal thickness fretboard on the Weiss to add some strength and stiffness in the neck area, but you can go with lower thickness if it helps your bridge height. The fretboard doesn't need frets just inlay markeres. I ended up with a modified version of my normal bridge but slightly taller:




I look forward to seeing progress pics.

With the nut being as tall as they have to be do you have to do anything to keep it from pulling towards the tuners, are they wider?

I plan on finger picking may use a thumb pick.
I do a little bottleneck but have not played lap slide.
My only steels are a homemade brass bar that I rounded the bottom on and a 1/2 deep socket. I will be mainly be trying bluesy stuff so I will probably pick up a shub sp1 bar sooner or later.

I have some Birdseye maple and was thinking of using it for matching fretboard (thin 1/8 to 1/10) and bridge and binding. I have not seen a Birdseye bridge on a flattop yet though is there a good reason?

I have decided on the doug fir top I think it will stand the tunings better, besides I think the crispness will really give it a unique voice.

The tone faerie are still arguing over two different thicknessing-bracing-sound hole placement schemes.
I ask for your patience and input once they are done (hopefully a day or two).

Wow Dave, I followed this thread to your website and watched you build RED KITE. I'm impressed.   

Now back to this regularly scheduled thread.

Kirby,

I used the normal nut width. The break angle of the strings keeps it in place just fine and it is against a high edge as you have the top plus the fingerboard. I just superglued 2 normal size nuts one on top of the other but will eventually buy a dobro nut blank from Stew-Mac:



I'm sure maple has been used for bridges. For the sort of instruments I make I think it would be a bit too light in weight. Also check the grain orientation - is birdseye maple the one that is flatsawn?

Looking forward to seeing your plans.

Bruce,

I'm glad you enjoyed the Red Kite build - I haven't had so much fun instrument making for a long time. I'm making another now for my daughter's 21st Birthday present in early February.
