Violin Bow i/D & Cleaning question

Recommended Posts

Intrigued with this small violin bow measuring 69 cms - plus I am wondering how to clean the thread lapping. The backplate looks like it has two pins with one being placed off centre that I have not seen before. The adjuster is frozen so I will get some Coke in at some point... I am assuming this is German but I am wondering if it could possibly be French with a later German adjuster..be interested to hear thoughts. Thanks.

Nice photos showing the Pernambuco cell walls. What camera are you using?

Thanks. Just a little Olympus TG-5 that's good for the beach ...and photographing bows :D

My camera is useless for close ups, but great for picking out buildings 30 miles away. It's really weird to look across 30 miles of landscape from the top of a hill down to a distant town and everything in between.

I do like to see those cell rings in a bow photo. I would also like to know the answer to your question about cleaning the lapping on old bows.

Where are the cell rings? I’m not sure what to look at.

If the frog mounts are silver and the one left adjuster ring nickel as it appears to be the latter isn't original. Could be well french IMO.

For cleaning the lapping you can try a small lot of dish cleaner or hair shampoo with water applied with a brush and pat it carefully with a paper towel.

The cross grain wavy structure. I would call it reticular rays, but not sure if it's the right english word.:huh:

Edit: It were medullary rays I had in mind.

The lines running vertically down the head in these photos. They also appear as rings around the stick about half a millimetre or less apart, so you may need your extra strength reading glasses to see them. Abeille wood doesn't have this feature.

Can you show a photograph of what you’re describing? I see the lighter colored streaks in the wood, which I realize is the grain. Lignine Is the hardwood and cellulose is the softer wood But I’m not sure what you are referring to when you speak of the cells.

Nor does a great deal of pernambuco ...

Put your extra strength reading glasses on and use bright light.

El Duce's photos show them above about half a millimetre wide in the head of his stick.

I believe the technical term is  Procumbent ray parenchyma cells, which are radial, that is at 90 degrees to the grain. So where the grain changes direction along the stick they remain at right angles to that change of direction.
