  1. It does seem that the group d is the most important. Wow. That's not what I wrote! The ground is. It changed that one to group too. AI is such a help at times. It won't even type AI!
  2. I just drew up a half dozen templates of violins and violas. It didn't take long using ratios, and Kevin Kelly's circle technique, that I just learned at the last zoom MVA meeting. I have a couple techniques of my own! Best thing is: I didn't have to draw one clothoid! Some of the ratios are helpful. I did find that the Vieuxtemps del Gesu and the 1700 Gofriller, although very different, are almost the same top and bottom., The f hole placement is almost the same, and even the corners are almost in the same spot. the Vieuxtemps is slightly in on The upper corners. The much wider c bout of the del Gesu creates a much different look. They were probably built on the same form that everyone had been copying for years.
  3. I like the Japanese ryoba saws. Rip and crosscut. Replaceable blades. Sometimes you can find them on sale. I have a giant one I use for resawing billets and slabs. It's been 20 years or so since I started. I remember having a list. I got a set of cheap Chinese finger planes. They needed a lot of work, and I changed the blades to laminated Japanese blades. I don't even know if you can find them now. Same with my go to rougher, the Lei Neilson concave plane. I'd make one if I couldn't get that. They aren't hard to make. Andreas Preuss showed a trio of Chinese scrub planes that he uses: somewhere, I don't remember, but it was recently. I've just never been a fan of gouges. Planes don't move the bench around as much! I have half and half old chisles, and laminated chisels. Old ones are cheaper, and the steel is usually good. They may need handles. Some people love gouges, and have entire sets of them. Old junk planes are a good source of scrapers, or blades to use for other planes. The only real specialty tools are the peg reamer, and something to bend ribs on. Different sizes of drill bits. It is a lot of fun. Probably the most useful thing that I had in the beginning was a workmate bench. Really. It is big enough, and clamping is needed. It is small. It can fold up! I use mine now to set my shop air circulator/filter on. But at the beginning, hundreds of dollars on a beach was out of the question.
  4. Mushy. That's it! Very hard to get clean cuts. I guess I need the real deal. Thanks.
  5. I'm guessing that many violins are built on the same form. They copied it over and over. Tweaked it, filed it, filled it in. I think that del Gesu just made the corner and end blocks the way he wanted, and the form gave a minimum width. I copied the purfling of the Vieuxtemps del Gesu, and the Gofriller posters I have. They are certainly done on the same basic pattern. The del Gesu is almost the same front and back. It has the c bout pushed way out, but he kept the same radius. Tiny corners tight corners that open the inside area up. Even the f hole placement is almost the same! Drawing them out with tools is fun. By eye is a challenge. Without looking at something? I don't know about that. 5:20 and the light is fading fast.
  6. I took a photo of the wood, then decided to just cut it up. An hour or so later, it just needs ribs sliced off the edge piece. The check isn't deep, but it is outside of the button. The wood isn't perfect, but it should sound really nice. A quarter teaspoon of HHG and a tsp of water is ready to shore that up before I glue the halves together. The pre filter on the air cleaner is redder now.
  7. Nice work Thomas! I was just thinking the other day that I would go with your idea of a simpler rosette, the wood/parchment. Not good with names, I couldn't remember who had the baroque guitar! I have a tiny one in A started that will be more like a fancy Uke. I'll take off the upper strings, and have 8 heavier ones. I can't do any more until I get a bridge and a rosette done. I've been beaten by paper. What do you use for parchment? My small one in G keeps throwing bridges! I think I'll make it wider.
  8. Christian, I'm not usually a fan of straight on photos; I like revelations from 3d shots. But yours are always very well done.
  9. The top is quartered on both sets. The bottom isn't bad on one side, the other is slab. Just crazy grain. One set looks like the best option. I bought it as one set ,so if I get one I'm happy. At least there will be less chips! I'm trying to use what I have up. I have some wood for early 19th century guitars; sub parlor size? I like the one I made. It needs to be sawn, so I'd do the big slab at the same time. I DO have a nice chunk of curly Padauk, about .65sg. I made a guitar and a violin out of it. The guitar I really like but I really don't like the finish on the violin at all. Sometimes you win, sometimes you lose. I used a pore filler and I just don't like it. On a sample it looked great. I used Osmo oil/wax finish on the guitar, and it looks sweet. That might look pretty good. Very resonant wood. Make the tops, and let them decide what back they want to go with. I have a photo, but I don't know how to manipulate stuff on my Kindle!
  10. I like roughing things out in the winter. It is cool to cold in the basement. It isn't bad if you are working. I have boxes that I put "kits" in. Most have two instruments in each. One is left over. You know how left overs are? Maybe you will do them, maybe you won't. Sometimes something new is fresh, and more exciting. This is the old box: A Gofriller and a Montagnana. I've done both before. The Montagnana has a very high arch, and pointy corners. The Gofriller is more normal. But the wood choices? Koa and American Sycamore? I split a piece of maple into two backs, and will have an Englemann and a Sitka belly for them. I think that they will both be the Vieuxtemps del Gesu. I haven't really looked at the arching yet. I have a smaller Storioni viola plane I drew up from a book. It is in box number 3: I decided to make two, and one would be with much lighter wood, so besides the maple, very shiny mahogany, and box store cedar! The last box is another from a small photo. I have the Guadagnini viola poster, but I don't care for it. It is a little shorter, and it does the look in! I has a rather nice piece of wood, and the belly is like curly Sitka. The maple is thick enough that I'd like to take it to the millworks, and have a 4mm thick slice cut off the bottom. It is big enough to do a one piece early 19th century guitar. Now, what to play with first?
  11. The one I did the outline of is on page 182 of the Rattray book. I couldn't remember what page, so I scrolled through, and it is near the end! I have no idea what it is. Some of the drawings showed who the artists are! I'm not one of them. Hats of to them! But not just them. I applaud anyone who submitted a drawing, and opened themselves up to possible criticism. I don't know why people would do that; but it happens on some forums. I don't go on them! Some of the simple ones even have attitude. Like Jim's MEAN del Gesu inside a cello. Yesterday I made outlines of Montagnana and Gofriller violins, using the purfling lines of the fronts and backs with tracing paper. They are almost exactly the same, but they changed the corners, and the Montagnana has a somewhat wider upper bout. I'm pretty sure that the del Gesu patterns are just about the same; maybe a wider center bout on some of the models. One would think that since violins are so similar, they would be easier to draw.
  12. This forum, and another, is about the closest to socializing that I get! But it isn't pathetic; I enjoy it like Andreas. Happy New Year everyone.
  13. Good to hear that you are working safe! I like roughing in the basement in the winter. It lags behind the outside temperature. It's around 55 down there now. By February it might be high 40's. I like working in the sun on the deck when it's nice. A 75 degree basement the few times it's real not is nice too. We don't have air.
  14. I have nothing against power tools, or CNC. I ran and programmed CNC lathes and mills for 40 years. So now I just go by hand. I have a wooden plane that works good on cellos, and then smaller brass finger planes, and a Lie Nielson plane, that I'm not sure they make anymore. I think I'll make a couple more wood ones to have a range like Andreas has. You do have to have VERY GOOD chip and dust control when you take large amounts of material off. Just sawing a half dozen or so billets in half; planing them flat, joining them, planing some of the wedge off so they aren't 30mm thick in the middle; the outside filter on my air filter got covered in dust. The hand saws are probably the worst offender, but even planing, there is some very fine dust. The filter draws it in, and what doesn't make it to the filter, is mostly under the bench it is on.
  15. Thanks Davide! Maybe I should try to download again. Being able to read the text and numbers would be nice. David Tecchler? It's pretty nice. I got the Guadagnini ones right. Edit. Tried again. Still corrupted. Photos and the front cover are fine.
