  1. Added! Do we need to add a "valid use in violin making" sentence?
  2. @Brad Dorsey Thanks! I don’t want the list to get too complicated...or for sure no one will look at it! So adding this sort of useful info in the comments will be wonderful! Er...I do hope there aren't folks actually eating hide glue.... I was more thinking about accidental consumption...
  3. "Wood" (pun intended ) it be handy to have brief "glue facts" all in one place? After almost 20 years of reading opinions about glue use with regards to violin making, it seems that confusion and misinformation hasn't really abated. ***This is very rough info. I'll edit/reorganize as I have time.*** Feel free to post info, experiences and opinions! For more detailed information on any of the following please consult Wikipedia. 1. Wood glue: catch-all term used for a myriad of glues used to hold wood together. Pros: Glues wood. Cons: Catch-all term. Can be confusing as to chemical make-up. 2. Hide glue: Made from animal collagen found in animal hides. Comes in different strengths; examples: 251 g (8.9 oz) is normally used for instrument building, 192 g (6.8 oz) is most commonly used for woodworking and the lower strength 135 g (4.8 oz) can also be used for general woodworking. Pros: Non-toxic if ingested (similar to gelatin). Does not creep. Can be "unglued" relatively easily. Cystals, if kept dry, have an indefinite shelf life. Cons: Crystals need to be mixed with water and heated - requires constant supervision. May smell bad. There are also different formulations available and not all are equal. Example: Liquid hide glue contains urea. 3. White glue or polyvinyl acetate (PVA)[hobby/craft glue]: Originally made from milk proteins AKA casein. Example: Elmer's Glue All. Also safe (if clean) and was used in classrooms. If yellow: called Carpenter's glue. Pros: Easy to use. Non-acidic. Used in bookbinding and as a wallpaper adhesive. Cons: Subject to degradation by various microorganisms. Will creep. Does not stick well to itself (when regluing). 4. Fish glue: A hide glue made from fish collagen, keratin or elastin. Different types of glue are formulated from different fish species/fish parts. Mostly used in various art endeavours. Pros: Safe. Cons: Weaker than regular hide glue. 5. Rice glue: A plant glue made from rice. Pros: Safe. Transparent when dry. Non-acidic. Reversible. Cons: A weak glue. 5. Muscilage: Made from plants. Edible. Historically used on envelopes, the back of stamps and for classroom use. Largely discontinued in favour of newer formulations. Pros: Safe and edible. Cons: Weak adhesive prone to drying out. Best for temporary use. 6. Cyanoacrylate (CA): A synthetic, or "plastic" product. Different formulations exist, such as thin and watery, a thicker gel or foam. Pros: Very strong. Easy to use. Cons: Not reversible. Can glue living skin. 7. Epoxy: A group of reactive polymers (thermoplastics). Pros: Very strong, comparatively chemically inert when cured, won't melt or dissolve in heat and humidity. Cons: Toxic when uncured, two-element, requires preparation, irreversible. 8. Polyurethane glue: Similar to cyanoacrylate. Multipurpose. Waterproof. Will bond different materials together such as metal to wood. Pros: While uncommon in violin making, may be used when installing certain geared pegs. Cons: May bond poorly. Short shelf life (~1 year). Toxic: contains carcinogens.
  4. Here's the exciting Part 2 of Chocolate's (AKA Gluey) resurrection! https://youtu.be/yLDLFa5uPcc ...and Part 3! https://youtu.be/LAS5OO0zvtA ...and Part 4 Final: https://youtu.be/Gyb1cKfkjig
  5. It's hard to find things to say (especially on the positive side), when there's really nothing to say, but yet, saying absolutely nothing seems rude...
  6. Woohoo! I am very excited. Make sure you keep us posted! (Living vicariously can also be very rewarding )!
  7. We all need to be validated!
  8. But...do you think some distributor used his name on bows...because it might have been familiar to people? As a marketing ploy? Do the timelines match up?
  9. Eugen Roth (January 2 1895 – April 28 1976) was a well known poet. Therefore very real! And he liked budgies! Example quote: „Ein Mensch erblickt das Licht der Welt - Doch oft hat sich herausgestellt Nach manchem trüb verbrachten Jahr, Daß dies der einzige Lichtblick war.“ ...which is actually appropo to our current times! He musta seen the future!
  10. Well..."good" is rather vague but we use the term all the time. So "good" could refer to any/all of: function, structure or aethetics. No?
  11. Are you certain there wasn't limited choice? I would have thought it was more difficult to import materials back then and that there was a "waste not want not" mentality. Maybe they wouldn't select a "less than perfect" piece of wood to make a bow for a royal patron, but for the rest of us? Why waste the wood if the consumer wasn't fussy?
  12. Hmm. Maybe? Maybe they didn't have a choice? Limited supply? Maybe it just didn't matter to the consumer? Good question.
  13. Once again...this whole "make the world a better place' approach just doesn't seem to be very logical. For the sake of argument, let's assume all animals used in human consumption are treated well (and there's certainly a lot of work that still needs urgent undertaking in the area of animal welfare). At least animal products and by-products are eco-friendly. If we go solely plant-based, there are serious ramifications from a health perspective. While some vegans have managed to remain healthy, many have not. Our species has evolved as omnivores. No matter how cute one thinks the bunny is, in the past couple of hundred years (or less) we haven't remotely evolved to be herbivores. There are also issues with the production of vegan leather and some of the other plant based products. Additionally, if we go with synthetic products...then what? We are mining and using petroleum to create those products. What does that do to the planet? And just look at the current plastic waste we produce and what that's doing to the planet. We've known about the severity of the plastic waste issue for 30 years and what have we done in all that time to curb or minimize the threat? Nada. Soon we'll really be grasping at straws (pun intended). We know about the clothing waste crisis. What have we done about that? Nada...we've made it worse with fast fashion. What about energy need to keep us warm/cool? I think we can kiss the wood burning stove good-bye. Coal? Nope. Electric? Dams? If we go solar...then what? Solar batteries need petroleum products. Solar batteries are not easily recyclable. If we go wind power? We need petroleum products. If we go nuclear? Ditto. Hydrogen? Governments need to step up - and quickly - and reduce consumption-related environmental issues. Putting the onus on the individual is beyond ludicrous. Number one, it's next to impossible to be fully environmentally friendly as an individual. Just try and grocery shop and NOT bring home plastic. Secondly, the vast majority of us are too self-important and/or lazy to bother making any extra effort. Even companies in the recycling business aren't doing especially well. For years, our local recycling companies wouldn't accept tin cans. Like really? How is that even possible? Tin cans have been one item that has been recycled for eons. The few individuals that do manage to live as zero waste as possible (and kudos to them) are just a drop in the bucket. There are so many 'no brainer' things the world could do to make things better...and don't. I understand the 'bottom line'...but seriously...if you have to, charge more for our products...(example: why don't we have universal cables? Why wasn't that an obvious choice from day one?).
  14. I honestly don't understand the current minority/majority weight given to certain topics/situations. It always seems that 10% of the population tries to dictate how the other 90% should behave. Anyhoo...according to the internet...vegans and vegetarians etc. make up 14% of the global population. Dunno what percentage of violinists are solely vegan...
  15. Technically...yes. But I wonder how mining figures into vegan ethics?
  16. Maybe they can't provide more info...patent pending? I think, from the little I know, that there's probably a lot of undiscovered glues out there.
  17. As I said...asking questions is always good...but sometimes I wonder if there's disbelief for the sake of disbelieving. Kinda reminds me of the time,while I was looking into my family history...an "expert" told me I had to be Mennonite. Er, no...both sides of the family are Lutheran - since Luther nailed papers up on Cathedral doors (vandal that he was). Apparently that was just impossible!
