  1. old watchmakers that did not have the correct size would make a tap by filing 3 sides of a threaded screw or threaded arbor they made using a screw plate. Generally the triangular shape would act as a tap in steel if the depthening was not too deep as would be found in a high thread count screw. I would guess that bone would be easier than steel and would give even from a brass screw if hole was right size. check your old time watchmaker if any around. He may have screw plate the right size. good luck
  2. I have made 3 fiddles but dont play and am teaching myself to play as tiny town with no fiddlers. my questions: 1. How often is rosin needed and how do you tell if too much or too little. 2.Why are soft and hard rosins both needed. 3.Are strings noted by pressing on the flesh of the fingertip or with the nail leading. Thank you in advance for your help. You are all the greatest for putting up with an old man.
  3. The sharp end never works for me either. I drill a tiny hole through the soundpost half inch from the top. Use a bendable but stiff wire with a sliight crimp where it fits in the hole to keep it from falling off. lower the SP through the notches and position approximately and now the setter with the large end can push/pull the post in position. either use finger pressure on top plate or strings to secure post and gentle pull on the wire crimp releases the wire. Works for me.
  4. For other casual makers that shy away from the high cost of proper tooling I offer my solution to peg shaping that works for me. I made first a tapered bolt 1:30 to use as a smoother and another identical bolt with a rough channel ground into one side of the length of the taper. This is enough to ream out the drilled peg holes to the correct taper. I used pottery clay wrapped aroung the smooth tapered bolt to form the internal taper of the shaper. I sliced a narrow channel through to the bolt and removed the clay to allow for the blade. Caveat: clay shrinks as it dries so let dry slowly with mandrel bolt in place or allow by making a bigger tapered bolt to start with. Fire the clay. I used a dental kiln using care around 478 or so degrees for water of crystalization to cook out then slow increase till after 600 and again around 1150 or so where the silica converts. My final temp was around 1500 and slow reduction to avoid cracking the clay. I cobbled up a wodden shroud for the mess that allowed a blade from a sheet rock knife to lay perpendicular to the mandrel in line with a radius.Epoxy the clay to the wood shroud. The cut from the peg is thus really a scraping rather than a shaving like from a pencil sharpener. This gives great control and no gouging. In Use , it is necessary to place a thin wooden strip on top of blade and a small C clamp to hold it. careful turning of the peg reduced the peg. I also regound the entering edge of the blade into a curve so the peg doesnt cut a shoulder as it enters the shaper but rather an arc. Cost less than a buck or so and way better than jewelers files I had been using to dress the peg holes. I can e mail a pic if anyone is interested. It could stand a facelift but works well.
  5. I ask the regulars to indulge me in a deviation. As you are skilled in pianos how does one clean the dust on a grand sound board from under the strings when a vacuum doesnt get it. Thanks much.
  6. Viewing pictures on the net indicated drilling many holes and then carving out the remaining wood to hollow the plate. I did not pick up on the fact you had to tip up near the c bouts to keep the drill perpendicular to the outside surface. A short section of wooden skewer neatly filled the hole though! Later the same plate has an extra line of glue showing where a base bar had been stuck that turned out to interfere with sound post installation.It works better on the base side. I am learning to embrace Murphy and his law with dignity.
  7. I too am confused. Under what circumstances do some images come up right on the post while others provide a link to another site. thanks much for any information.
  8. dont get psyched out by these great pictures, just be like the bumblebee that doesnt know the rules of physics says he cant fly and just does it anyway. Im thrilled with the neat tips of another way of doing it, and many thanks again Michael
  9. If a violin was constructed using generous amounts of liquid hide glue......even an extra bead on the inside after the assembly had dried. Is the construction fatally flawed as to taking apart? If not, your recommended procedure. Thanks again
  10. Thanks to you all for the replies. I too have a bunch of red juniper fence posts that I wanted to try and use. The stuff is beautiful, at least 70 years since they were cut in the Missouri river breaks and very hard as evidenced by the bent staples. When the snow drifts leave I will see how the stuff works.
  11. I saw a guitar segment on tv and Martin sucessfully uses a number of different woods for guitars. As the devils advocate, is spruce and maple really needed for a violins sound or just because they are traditional and beautiful? Wait one while I duck for cover. thanks.
  12. heck just galvanized tin from a piece of stove pipe or even a cut from an old paint can or coffee can or bum a scrap from your favorite tin shop works great. 29 guage is fine and bend wire handles and pop rivet em on. they wont rust readily, wont work harden like aluminum and wont stain like blued steel shim and are not spendy like brass. good luck and keep warm.
  13. oh dear! Xania what a terrible place for a typo..........surely you meant to type slim rather than slimy, If this is not so watch out for your next repair charge. This was a fun thread.
  14. Found 2 neat violins (loose translation) in the Lewistown MT museum. one is handmade by Metis/shoshone indians. the metis derived from early french furtraders that took various tribe wives. The other is a true cigar box model made when havana cigars were readily available here. go to www.msnusers.com/clockdoc and click on "pictures". Each will enlarge if you click them. tried all day to get em on maestronet but not smart enough yet.This is not important but is sort of fun.
  15. does anyone know what brand of violin jack benny used as a prop on his appearances. thought it was strad, friend says not.........thanks a bunch
