    Looks good as a source. Are the scrolls actual outline or just generic scroll with bunch of numbers?

    What is the back length / stop of that one? Which del Gesus are the "short ones"?

    All of this will be on the poster. It is worth purchasing a couple of the strad posters - Titian, Huberman, Viewtemps, Brusilow are good ones with CT scans. The Dancla is a good poster also but the violin in HUGE.


  2. If you are just star

    Sorry to be the guy to resurrect a post from the past, but did anyone ever standardize and make decent molds and templates?  I am looking to make my first violin and saw this thread before pulling the trigger on the International violin set.  Thanks

    If you are just starting out, personally I'd only use the Strad form drawings as a reference. The hardest thing to get right (for me at least) is the corner shapes -- if you follow the stard froms accurately you'll wind up with an outline with corners that look tighter than what we see in finished instruments. Fortunately the Strad has some great posters with full size CT scans of the rib garland. You can trace it and use it for your template (correcting symmetry or not depending what is important for you. Although the CT is a bit fuzzy the Titan drawing is a great place to start -- it is a nice strad - not to big or too small. The other is the Huberman.

    I have a set from Dictum, from 5.5 mm to 10mm in i/2mm steps. They're very reasonable and  work  very well.  

    In order to centre the pilot  drill properly, I use a thick piece of plexiglas with a series  of  concentric  circles  scribed on it, and a guide hole in the middle.  I can look through  the  plastic,  line up with the f hole eye, and drill through very exactly. 

    brilliant idea thanks


  4. ha not too scary but a couple of other things I found challenging...

    Working in a small space is really difficult -- one needs a bit of elbow room around the bending iron to work efficiently -- kind of hard in a 8 x 8 ft shop. I can barley fit a Cello on my bench!

    I found it easier to fit the ribs with the form secured in the tail vice so the form rested at a 90 degrees angle to the bench - easy for the first 5 ribs - kind of hard for the las one!

    I had to work really fast when gluing. Because the ribs are thin and cover a large surface area - i found if i used too much glue, I got a bit of warping even before the clamp was secured. I used a hair dryer on the highest setting to warm the parts before gluing and this really helped

    also one more thing - i cut the blocks with a gouge and rasp and for the most part left things fairly rough - I think the texture helped with gluing. I made this sanding thing in the shape of a bending iron -- a few passes with this  really helped keep the corner bits that meet the form and joins nice and clean.

  5. Cello rib garland. First cello. The amount of effort and skill required to build a nice rib garland was much more difficult than I thought - far greater than a violin or viola. Bending the corners required basically all my strength to hold the bending strap fast around the iron to set the bend. Twisting and warping was an issue as well, even working carefully i had to correct twist throughout each bout before gluing. Lastly it took a bit of patience to get an invisible joint between the lower bouts. All and all i'm fairly pleased with the result. The curves follow the outline fairly closely.

    Jeff is a cyborg.  He'll be doing this until the end comes.  And just before that, he will blast off in what he has disguised as his cabin and take up residence -- along with Maestronet -- on another habitable planet where the native species sports two heads, allowing a single virtuoso to play both parts of Bach's D minor concerto to an audience twice the size of what a hall normally would accommodate because every one has four ears.  

    I may have a future as a futurist.

     

    All joking aside, Jeffrey is actually our moderator not the site owner. The business owners of the Maestronet forum and servers are based in Toronto. Sadly if Maestronet closes shop (which I don't think it will any time soon as it is an easy source of income for the owners) Jeffrey's posts will disappear along with everyone else

    Who will take over when the long time admin people and main contributors pass away? Does anyone else wonder if the website will continue without these main characters and what will become of all the data?  Is there a plan? Has this been discussed before?

    I think this is a serious matter. Our hosts (based here in Toronto) could decide to close up shop at any time (not that I think they will as the site provides a ongoing income with comparatively little investment). But if they do decide to turn the servers off all the info here will be removed from the public domain. This is one of the reasons why I helped pull together the Bass book -- this important IP now exists in a shareable form that will endure. But there are countless posts from knowledgeable contributors that will disappear if and when the site closes.

    What is a cello piccolo ? I am trying to find information about a very early cello (?) with a body length of 710 mm. I have never made any "early Music" instruments and am a bit perplexed by references to Bass Violins and other instruments which I assume were transitions between the viol family and the violin family. Any info appreciated.

    There is a very nice book called The baroque cello Revival by Paul Laird that lays some of this out. It is kind of an oral history with interviews from key players (including Mark who posted above)

    The bass violin refers to the early cellos (e.g. Amati King, Strad Medici etc) meant for bass accompaniment in early music. There are many early music recordings out there that feature copies of the Servais strad

    as for the Violoncello piccolo - Bach used it in 9 cantatas - inc bwv 41 - there are recordings out there that use the Fleming Amat, Jackson notes above. You can hear what it sounds like here 

     


  9. I use two 3 overhead lights for general lighting, 2 bench mounted lamps from IKEA -$10 each! these are the old ones with the on off on the lamp shade -- these are much more useable than the new ones which have the on off on the cord. 

    I don't do re-touching, but I have an OTTLITE with a full spectrum CFD bulb for times when I need to see accurate colours

  10. Just added a small Miele vacuum as the last piece of my shop dust management system. It may seem like an odd choice for a shop but it is perfect for general clean up of dust and debris that doesn't get captured in the box fan filter or swept up. It has plenty of power, a floor attachment, hepa filter etc. And it take bags which means i dont have to deal with allergy attacks when cleaning a shop vac. It also super quite. This unit was an end of the line model so it cost only margnaly more than a small shop vac
