delicate sound hole reinforcement


Instruments- discuss specific features, luthiers, instrument problems & questions

I have seen many sound hole designs on here and was wondering what you use for reinforcement under and around those intricate designs.

How is the COVID-19 coronavirus affecting you?


OFF TOPIC discussions

I had my first covid shot two weeks ago.  I was  impressed by the professionalism of the volunteers and how organized they were! No after effects other than a VERY small tender spot for 3 or 4 hours. I go back Mar 4th. It is only about 5 miles from the house.  I got a Focusrite recording interface so will try some recording tomorrow since they probably will not have the roads clear. It will be a good day for that

How is the COVID-19 coronavirus affecting you?


OFF TOPIC discussions

Covid has had us inside for way to long!  Heavy snow now will require firing up the snow blower so at least I have reason to go outside.   Not so bad though electric start and heated handle grips. 

 Just a reminder that better times are coming, just be patient.

Bridge feet contact area


Instruments- discuss specific features, luthiers, instrument problems & questions


I have completed a "what if" all poplar hourglass instrument, 26.5 VSL and the fretboard "floats" it is only in contact with the top at the peghead and tail block, otherwise about 3/16" clearance full  length. The bridge rests directly on the top with no contact with fretboard. Right now the bridge feet each have about 1/2" x 5/8" bearing on the top.  A previous trial build has fretboard attached but stops short of the tail block. It is walnut with butternut top.  The two  builds have very similar volume and tone. I was thinking of decreasing the footprint of the bridge on the top to see if it changes anything.  Both instruments have bracing under the bridge area.    I am going to go to a size heavier strings also on the poplar instrument. Does anyone have any thoughts on this?

Hollow or solid fret boards


Instruments- discuss specific features, luthiers, instrument problems & questions

Has anyone made  a comparison of hollowed out fretboards compared to solid ones  as far as warping is concerned? ? I know solids are quieter and it seems the hollow  fretboard would be less prone to warpage than the solid one. Also the wood grain ,  and flat sawed or quarter sawn has a lot of influence on warping.

"Floating" Fretboards


Instruments- discuss specific features, luthiers, instrument problems & questions

Ken,

 I realize the fretboard is glued to top somewhere, I was thinking along the lines of gluing the fretboard only at the head and tail blocks and making the top a braced single unit  with just a fraction of clearance between it and the fretboard  and setting the bridge on the top instead of on the fretboard

"Floating" Fretboards


Instruments- discuss specific features, luthiers, instrument problems & questions


I know there are builders who "float" their fretboards. I am sure there are discussions on methods and pros and cons for this.  Have  any builders made a comparison of floating versus glued to top? Thanks

Curved back dulcimers


Instruments- discuss specific features, luthiers, instrument problems & questions

Thanks Dan, the soak and heat  process was in my mind.  Did you notice any advantages to the curved back other than looks?

Curved back dulcimers


Instruments- discuss specific features, luthiers, instrument problems & questions


I have noticed several builders are making their dulcimers with a curved back.  Of course bracing would be needed but when you speak of the curve, how much deflection are you working toward? I can see where the curve should reflect a little more sound to the top and if the top were isolated from the fretboard you might get a little more volume. 

Any thoughts would be appreciated

Strings!


Instruments- discuss specific features, luthiers, instrument problems & questions

I used stewmacs nut and bridge files to cut  the grooves, and yes  it is only on the open string note. 

Thanks for the suggestion, I will give it a try

Strings!


Instruments- discuss specific features, luthiers, instrument problems & questions

I have built several dulcimers from 16" to 30" VSL.  The latest one has 30" VSL, Lower bout  is 8 1/2", upper bout is 7"  and is 2 " thick. Sides and back are walnut and top is ambrosia maple.

I started out with 12,12,16,24 strings and the melody and bass sounded fine, smooth and mellow, but the middle string has an odd twang . I used Struthers string gage and it recommended 9,9,12 and 18. after switching, I used 10,10,12,20. the middle string still has that strange twang. My instruments all have zero fret but could the problem still be in the nut that keeps the strings in position? the bridge was originally ebony but I changed that to bone . Still get that off sound. Action is very low as I dish the fretboard slightly  midway to allow a lower bridge, could it be too low? No buzzing

 

I appreciate any thoughts

Group sync


Playing and jamming difficulties...HELP ME!

Thanks for the suggestions, We had a practice Tuesday with 14 players and the four guitars were side by side, with the 10 dulcimer players in a tight circle inside. Even with the new songs we tried, it worked very well

Group sync


Playing and jamming difficulties...HELP ME!


 I belong to 3 central Indiana dulcimer groups and we often play together at local events. 

The problem arises when we have more than  6 or 8 players. Some players are advanced others relative beginners.

Usually we have at least 1 or 2 guitar players but still have problems with group sync in the larger group. Do you pick some one to lead and everyone follow them? One side of the group will end  up a note or two behind or ahead of the other side . We don't use electronics so it is difficult, especially outside to keep everyone together. Other that very frequent practice, does anyone have suggestions?  We play together weekly with portions of each group involved

Thinking About Buying a Ban Jammer


Instruments- discuss specific features, luthiers, instrument problems & questions

I have built 4 "banjammers" or as I call mine, banjo-dulcimer. A practice drum head in 6 or 8" diameter  either set on a dulcimer shaped 1/2" thick board or suspended in a round based dulcimer body. Yes they are loud and alone they are fine. In a group sometimes I put a 1" wide piece of sponge rubber under the head before putting tension on it. then usually rest  pinkie and ring fingers on the head to further mute it. The dulcimer group s that I jam with seem to welcome the addition. The only complaint I have is that above the 11th fret it loses a  little ring and clarity
