I previously mentioned the Gilles Nehr Tete Beche violin bow in another thread that went completely un-noticed except for Fiddlerman. The ideas in the bow are very exciting to me and makes the process of bow rehairing a simple matter for the violinist without the need for a luthier. I strongly recommend looking at his Youtube videos and web page. The recent Fiddlerman blog item of a titanium frog appears to be derivative of Nehr's work.
I really want a bow (or several) like this but do not want to pay $6,000. So I am going to try to make them myself starting with carbon fiber bows that were unfit for conventional rehairing by having super glued maple hair wedges. I obtained several of these for about $10 per stick.
My next step was to look around for a light weight and ergonomic thumb screw for the frog end. I did not find much of interest until I found an upgrade to a GoPro knob called Maximal Power CA GP CNC Screw (bk). 3 come in a package for about $8 on Amazon.
Perhaps overkill, but I wanted to obtain an axial bearing for the thumb screw with a 5 mm ID and 10 mm OD. I got 10 for $5 with shipping from China.
I already have a Proxxon pantograph engraver so I will start proto typing the tip end next week.
