  1. I have a friend who has been trying to find a good tape to use as a protectant on a cello but can't seem to find what she's looking for.

    What brands do you recommend? Product numbers would be helpful too.

  2. I think nowadays makers dont have to make a dozen or more a week any longer to make a living ,so they can afford to take time on details ,Same can be said of violins ,etc... todays instruments are often far more technically accurately made than years ago but i think they become slightly sterile looking.

    One example of quickly made ive brought up on here several times but no-one ever provides an answer. Peccatte supposedly could make several bows a day over a very long working life. Peccattes make big money but where are all these lesser quickly made Peccattes. The only reason i can see is experts refuse to name bows as Peccattes if they are lower quality possibly for market reasons. Instead many are described as Peccatte school ,workshop,etc... with no real attribution.

    I'm sure if he was able to make several bows a day there were people behind the scenes making pieces for him. Partially finished frogs, buttons and roughing out sticks would be huuuuge time savers.

  3. Thank you for posting this. What about that "electronic mother mounted behind"? The mother I already have is plenty, thank you very much.


    Are you sure you don't need another one? You might be able to program an electronic one to bake you cookies on demand.


    Sorry Mark, that might be a typo. I'll have to check. 

  4. This also goes for bows! Please if you are going to use a lubricant on a screw PLEASE make sure it does not have silicone in it! If the silicone gets into a crack you won't be able to get it out without using some harsh chemicals which could further damage your bow. 

  5. Kate , you know that he´s listed in the Grünke /Schmidt book about german bow makers vol. II p.86 with some biographical information and pictures of a bow?

    Best regards Mat


    That's where I first heard about him. Unfortunately he was only 31 when he died, it does have a few pictures of bows but no picture of him. I wanted to find a portrait to hang on our wall next to Dodd and other bow makers that line the staircase. I don't think it mentioned the number of bows he made so I'm curious to how few there are out there.

  6. In case you don't succeed at finding a genuine photo to put up in the workshop, perhaps we could offer some substitute candidates? :)


    How about this? (I think his name was Fabio Mohrzoni, or something like that)



    If you zoom out he's actually holding a violin and bow....

  7. Has anyone ever heard of Peter Mohr? He made bows in the 1960's his brand was frenchified to Pierre Maure. I thought it would be really cool if we could find a picture of him to put in our shop. Has anyone ever seen a picture of Pierre Maure or seen any of his bows?

  8. After an hour of straightening the horrible kink behind the head has been relieved and the bow is straight. Now you can look down the bow without fear of straining an eyeball. 


    A new wrap and leather thumbgrip and the bow is now finished. Now I have to stop goofing off and get back to making bows. 10421277_563918027071694_897577356469929


    p.s. I decided on lime green instead of teal. 

  9. I think that's the first time I've heard of those instruments, I've seen them before but didn't know what they were called. It looks like a majority of the bows used on those types of instruments are clip ins or a type of clip in. I haven't made a clip in bow yet but that sounds like a fun project for between now and the first of the year.  

  10. Some people have been using phenolic resin for finger boards, pegs and frogs rather than ebony. You may be familiar with the counter tops form back in the days of high school chemistry class. It absolutely destroys your tools. 


    I think one of the reasons that ebony has been a popular wood is because of it's consistently small pores. We are lucky enough to live near Keim Lumber in Amish Town, Ohio which is essentially like a Cabela's for wood workers. They have a great exotic wood section there that we browse, we're always looking for alternatives to ebony and pernambuco. We might pick up a piece here and there but it always seems like it is too weak, or the pores are too big or the sound just doesn't travel through the wood very well. There are a couple woods that we have found that work well as substitutes but they don't have a standard name and when we ask for this specific kind of wood there may be 3 or 4 different types that come up with the same name. 


    Anyway, what I'm trying to get at is that with a wood that is as dense as pernambuco how would you laminate (which is what it sounds like you're doing) it and be able to assure the customer that it is going to stay in one piece over time? My dad made a laminate bow (with a 4g thumb drive in the frog) out of thin laminated pieces of wood, he has gotten several inquiries about having another made or selling his but he won't because he can't guarantee that it will stay in one piece. 


    What kind of long term testing has been done with this type of material? Do you think it will stand the test of time or should we just hope it holds up until after we've retired?

  11. Martin, I respect your opinion. It is a shop bow but we believe it is probably from the Bazin shop. It can be very difficult to tell what kind of wood a bow is without holding it in your hands, I assure you it is pernambuco and probably made by a boy who should have been in school.


    I'm going to go with what my dad says about the bow since he has been in the bow business for over 30 years and is highly respected in his field. 

  12. Can someone tell me why bow boring isn't done in a lathe? It seems to me, admittedly someone who knows next to nothing about bowmaking, that the bow stick could be passed through the headstock spindle and gripped in a four jaw chuck, for instance. Then the drill bit could be held in a drill chuck mounted on the taistock. I only ask this for my own curiosity. Thanks.

    It can be and is done that way by many makers, especially when it comes to bushings. The problem is the drill bit likes to follow the path of least resistance which of then leads to inaccurate drilling.

  13. You put out fires with alcohol?

    As crazy as it sounds yes. Make sure your flame is out first, but the evaporation makes it cool quickly.

    According to my confined experience from reshaping of relatively cheap bows, the use of small heating plate is more safe than the use of focused heat from spirit lamp.

    Every person/shop is different, some heat bows with a hot air gun, some heat them in ovens and some use alcohol lamps. Our shop is very traditional and we use an alcohol lamp because a pot filled with hot coals is impractical.

  14. Oh sure, if it's a Bazin it's worth fixing.

    Is that the final tip thickness? The tip looks disproportionately thick, perhaps because it's a 1/4 size bow. And, in view of the ivory situation, what material is the tip made from?

    I could have made it thinner and more proportional to the size of the bow but from what I've noticed about the smaller bows is the thickness of the ivory/ivory-like material is thicker and closer to the thickness on a full size bow. Maybe it adds strength?

    I used Tip Armor rather Mammoth or plastics. It is available through David Warther. Because the material is woven it gives it strength. The weave pattern is visible without it detracting from its traditional look.

  15. My shop policy is not to attempt to straighten anything I can't write a check for.

    Sometimes makers who have stained bows don't neutralize the acid they used. So if you are using an open flame to heat the wood to fix the twist you need to have a spritzer of alcohol to squelch any burning that may occur.

  16. That is very nice work, but is that bow really worth it? Can you sell that bow for enough to justify the work that you have put into it?

    It's a Bazin, we are thinking Retail on it will be $750. Retail on my 1/2 size Bazin is $1,200 and it is with A very nice high end shop. They have a great clientele for these small bows.

    Since I got it for free, and there isn't that much work in it I'll definitely make some money on it. My prices for repairs are low because I just started my business last year, I only do to the trade work and the businesses sending me the work need to be able to make money off of me.

  17. My dad brought home a 1/4 size bow for me from his trip to the Skinner's auction. It's an adorable little bow. I recently did a double chaval on the frog of a 2/4 size but this bow is even smaller. 


    This one didn't need much work just a new tip, slide, wrap, thumbgrip and a ridiculous about on straightening and camber. 

    To give you an idea of size I took pictures of the head and frog next to a quarter.



    Old tip



    New tip



    Frog had to have a new slide, and the ferrule reshaped. 



    The button was covered in scratches like it had been chewed on.



    Doesn't it look better now?10384577_562187010578129_569160048151313


    Now I just have to rehair, straighten, camber, wrap and thumbgrip. I'm thinking Teal and silver tinsel for fun.
