Re: New to Music Instruments

The only real difference between a chromatic and not-completely-chromatic version is the number of tines. Build whichever version you want. Once you learn to build and tune one tine, you know how to build all the rest.

Re: New to Music Instruments

You are correct that different materials will tune a little differently. In the video you originally referenced, his longest tine is about 5" (13 cm), based on the size of his hand. That is just a little longer than you found was the lowest practical pitch, probably because he is using rods and not ...

Re: Repair of Zither (Harp Mandolin) ??????

Don't worry too much about steaming the joints. If there is any place you can gently work a knife in, the old glue usually literally pops apart with no water/steam. Just work around the edge slowly. If you have one of the small wire brush tools for the Dremel, it may clean up the lower 20% of your p...

Re: New to Music Instruments

The only real use of the eye bolt is to tighten the tine down against its two supports, so the only place the eye contacts the tine is at the top. The inner diameter is irrelevant if it is big enough for the tine to fit through. The hardware store eye bolts will do that just fine, just be clunky. Lo...

Re: New to Music Instruments

Look at his test jig at exactly 10:00 and the assembly process at 15:38. For anyone else following, we are talking about this video.

This style of eye bolt is available at Home Depot. It would do the job, but wouldn't be quite as pretty as the ones he used.

Re: New to Music Instruments

The video says he used M5 eye bolts. M5 is a metric size. There was no screw on top, like you drew. This bolt sat between the holder and bridge and the string went over the holder, through the eye bolt hole, then over the bridge. He tightened the bolt with a nut on the opposite end to secure and tun...

Re: Repair of Zither (Harp Mandolin) ??????

Have a look in our Library for discussions on spool clamps. They are easy and cheap to make. Think 2 sewing thread spools on a long bolt with a wing nut at the end. Go to Home Depot and get a bunch of 6" or 8" long 1/4" threaded bolts, and some matching washers and wingnuts. Also get a short piece o...

Re: Repair of Zither (Harp Mandolin) ??????

Hi Caley, and welcome to the Forum. Sorry there hasn't been much interest in zithers here lately. I was given a similar one last year, but I have yet to get around to cleaning it up. Don't worry about your lack of skills, we have all been at that point before. You have the interest and drive. Just t...

Re: Cutting rosettes by hand?

I looked and found a number of discussions that mention the popsicle stick tool (apparently originally described in Cumpiano & Natelson), but no actual pictures of one. I did, however, find a couple fancier homemade tools using the same principle. At least one of these is probably the same tool link...

Re: Cutting rosettes by hand?

Here is a very old method, and I'm sure there are some references to it in our library. Stick an X-acto or surgical blade perpendicular to the length in one end of a popsicle stick, then drill small holes at the inner and outer radii. Put a small nail at the center of the rosette, and turn away. It ...

Re: Looking for information on Portative Organ construction

This guys has some nice diagrams and says he will send a booklet with his plans for free if you ask: http://www.johnboersma.nl/mini-orgelconstr.html
There are also some homebuilt portative organs on YouTube, some with wood tubes, and others with PVC to give you some ideas.

Re: Adding a reinforcement to a neck...

Nothing new about an offset shape. I stole the idea years ago for my cittern, and love how it feels. The hand is nowhere near symmetric, why should a neck be? The simple answer is just that it is easier to mass produce.

Re: Where is silver solder used, good ,bad?

Pain, and more expensive. The melting point is much higher than normal solder, so you risk damaging semiconductors and other components much easier. The resulting joints are stronger, but also much more brittle and sensitive to shock.
