  1. Mike, have you checked your bassbar placement? The main problem with narrow f-holes (less than 40mm) is the bass placement may partially cover the upper f-hole. The Soil has ff-hole distance of 38.6mm with C-bout of 108.5 mm. It supposedly is a great violin.
  2. Yes it does cut. After grinding the toothed edge you are left with a fine flush cut saw... very similar to a flush cut dowel saw. It is a very controlled cut and if you shine an led strip light you can monitor the progress.
  3. This comes from the Strad 4 volume measurements pdf. Unfortunately it is not summarized in a table but is given for each instrument. My previous comment was based on an overall generalization that Strad violins got bigger every decade as he changed his mold ( I believe there are 12 molds) Here are the specifics of some his narrow earlier violins: name: length : upper : middle : lower : ff-spacing ... (mm) 1669 no name 355.5 162 105 202 37 1670 Sachs 352 158 103 196 35.5 1679 Parera 354 162 1 05 202 36 The other reason I am asking about this is that I have some very nice wood that is a bit narrow ie 204 mm wide or 8". I could add wings to get the standard 210 mm but to keep the symmetry of 204 mm lower bout the width of the C-bouts and upper bout would have to be reduced a bit. Also I do not have a "small" mold version of a Strad yet and I was wondering if there is a good choice of molds from his earlier models.
  4. Some of Strad's earlier violins had narrower C-bouts and through the decades the C-bouts width increased from 102 mm in 1669 to 111mm in 1715. Is there an acoustic preference for wider C bouts? With the narrower 102 mm C-bout the upper f-hole spacing on that violin was 36 mm. The f-hole spacing for the 111m (1715 Strad) was 43 mm. With a standard bridge width of ~41.6 mm I presume that there may be an acoustic reason keep the upper f-hole spacing around 40- 42 mm which means a wider C-Bout of a least 110mm. Do the narrower C-bout Strads such as King Joseph, Ludwig, Jupiter ... have a good sound? Just curious
  5. I find a picture very useful. Here is an exaggerated example of what I understand grain run out to be. The edge of billet has diagonal grain lines that do not run the entire length of the billet. The top of the billet has vertical grain lines otherwise it would not be chosen a tonewood or would be cut so that the grain lines are vertical. This is a rectangular billet which has more symmetry (flipping) options than a wedge billet.
  6. I modified a 24" fine saw blade as a tool which can be used to start a cut into the upper block. The blade is 0.80 mm thick but I ground the toothed side to 0.35 mm and it works quite well to give you a perch into the upper block so that you can continue with a long seam separator. You can use it carefully as a saw since it has zero kerf to initiate a thin cut into the upper block.
  7. Here is a rib and neck repair I did a few months ago. It involved the standard button graft, neck reset, plexiglass counter form etc... I had some free time and I wanted to document the process for future reference. The hard part was replacing the small missing fragment from the rib. Before and after...
  8. maestronet server hosts its own images which us why images are still visible years later. There are about 130,000 images on the server. Adding a hard drive is cheaper than paying rent.
  9. I have sent a message to the site admin regarding this problem and hopefully things can be restored to the way it was. I only want to log in when I want to post a comment.
  10. I really don't understand why there are so many guests who can view the content. What browser are they using? I really need to view the content as a guest. I have written a python script that allows me to save a discussion in a very readable format instead of using the tedious cut and paste method. Is this a temporary situation?
  11. As of this morning there were 27 registered users and 75 guests viewing the content of Maestronet so it might just be something with specific browsers ... I am not sure.
  12. I used to able to view content as a guest but now I get "Sorry, there is a problem Something went wrong. Please try again. Error code: EX0" I have always been using FireFox. Clearing the cache and history does not solve the problem. This is a very recent problem. Any idea what the solution might be??
  13. Its been awhile since I posted. I am still in the process of setting up the ash, pear, maple and quilted maple violins after varnishing. i like to let the oil varnish harden for at leat 4 or 5 weeks before I polish and do the setup. Both maple violins are a dark golden brown; the pear violin is red-brown and the ash violin is amber. Here is the ash violin drying in the sun
  14. I can see trying this design with a spruce top, especially the increased thickness below the bass f-hole but I don't see the purpose of the supports (diagonal braces) for the back. Have you tried this with a standard graduated back?
  15. Just to wrap up... this violin was finished a couple of weeks ago and has settled in quite nicely. Now it is time to give them some sun before varnishing.
