Brandden, Mimmo Peruffo has given the density of Nylgut (which is his invention) as 1.30 gr/mm3. I don't have a tensile strength value for it. If you come up...
I don't know of this datum, but I recall having a conversation with Dave Thormahlen several years ago, where I think he mentioned it, and of course, I forgot...

I'm forwarding this to Chris Henriksen (Boston Catlines) as he may have the information you need. I have been using nylgut on a variety of instruments, and I...
I now have a shell. I had to use boiling water in the bath tub to get the poplar bendy board take the 2 1/2 in inside radius at the top end. But it bent...

K&P Ičve done this many times with wooden boxes and such. Here is my take, but it all depends on the nature of the inlayed piece. Generally, I make my inlay...

Epoxy likes to be stained with water-based products. I have used scenery paint to make black epoxy, just be sure to sift it and get the little lumps of chalk...
Generally, I use a toothpick with just a tad of standard tube paint tints. Ičve noticed that the siennas, umbers, and carbon black work well. Red and blue...

A little follow-up to my repair saga - The patient lived! [apologies if this is a duplicate post - it looked like the first time I tried to send this message...
Hello, Would like to set some semi-precious gem stones into to the pillar of a harp to add to the décor. Any thoughts about the best way to do this are...
Hi Christa, Epoxy would be good, you will need to find a type that will remain clear as some of them will age and turn a yellowish color. As for routing this...
Hello, Am needing to retire my 1978 Witcher wire strung Trinity harp. Am looking for a wire harp (in the USA) that is made from a solid carved sound box in the...
http://www.richard-york.co.uk/past/harpsmodpics.html That's the harp I want to make. I have the plans from Robinsons. But I've been doing a lot of reading,...
There are several harps on that page- I am assuming you want to build a Queen Maryish harp? However the plans must not be very historically accurate if you...
I'm restringing a Triplett Signature 36. Several of the eyelets near the bottom of the soundboard have cracked and bent from the pressure of the strings. Two...

Hi. These are most likely the plastic eyelets, that are set into the center strip, but this would also work with brass eyelets. Use a screw extractor to twist...
Robert, Often the eyelets have a flange that sits flush on the top of the string rib. You should be able to get under this and pry the eyelets out. It works...
Robert, When the pillar obstructs screw extractor or other approaches, I use a small screw driver to pry up an edge of the eyelet near the crack. You can...
... First, have you tried calling Triplett to see what their fix might be? I think I'd put a sharp edge on the end of a putty knife and try to pry the eyelets...
While doing a neck repair, I found that Triplett used a little glue in addition to the lag bolts for the attachment where the neck and pillar meet the sound...

Hi After following this discussion I was feeling fairly pleased that I had epoxied brass eyelets in a maple outer rib so I'd never have this problem. Wrong. I...
Hey Gang, I just sold the harp I had in my shop! People kept asking me if it was real and if it played right up till the customer picked it up. It was a great...
Pedal harp bridge pins are rather different as they fasten into a brass plate, not wood. For thick and strong bridge pins that fasten into a wood neck you...
A customer brought me a Salvi Aida, ca 1985 for restringing. It is also blessed with the dings and dents reflecting its age and use. The finish is highly...
Rick, It depends on the finish. For the Salvi, I think it's lacquer on the earlier ones but they may have gone to a conversion finish on the later ones. To...
Dear Rick, Maybe ask Salvi, what they used? I can offer you an italian translation of your question, if you like. Restringing: I recently measured the strings...
Hello! I'm new to this group and I hope I am in the right place! I'm studying the medieval harp, specifically the "Gothic" type which seems to have been used...
