To make my segmented saddles, I need four bone posts and two larger bones for the outermost E / e strings.
When bone postst are to be made, I thin the thickness of the saddle blanks to 5,0 mm and a number with a few tenths more or less thickness in my drum sander. The precision when I saw in the spruce piece for the segmented saddle is not completely perfect, it is good to have some alternatives. Then it remains to cut the thinned saddle bone blanks into pieces that are partly 5,5 mm and partly 13 mm wide. I have previously used jigs and a hacksaw for cutting, but it was hardly perpendicular cuts. It was also both laborious and difficult. Something must be done.
I found a small handy circle saw made of Proxxon, and KG 50. It seemed to be perfect for the purpose.
When I got it home, I had to work a little extra to modify it before I could start. There was a 5 mm gap between the blade and the clamp to be able to cut at 45 degrees. I needed to cut the whole saddle bone blank into small 5,5 mm long pieces, so I made some abutments to extend the jaws in the clamp. I used aluminum. In addition, the stop that came with it was very small and swaying and the width 5,5 was at least + -1 mm when I tested. It had to be a real screw as a stop instead.
A problem with the stop was that the cut piece easily got stuck between the stop and the blade. Since the blade has the consistency of hard bread, some broke. Now I use an approximately 3 mm thick aluminum plate between the blank and the stop screw which is removed during cutting. Then a gap is left when the bone post is cut to fall into and it does not get stuck and destroy the blade.
It works very well! Perfect 90 degree cut with the right dimensions and no sweat in the forehead. Each cut takes about 10 seconds. My point extraction (and face mask) is necessary as the sanding pad produces a lot of fine-grained bone dust. The flour is so fine-grained that it cannot be vacuumed off, you must use a damp cloth.
Just got home 200 new 90 x 12,3 x 5,3 mm saddle bone blanks made from camel bone from New Delhi in India. Clearly exotic! This is the third order from www.luxurynaturalcraft.com no problem. My contact person is Rashdi Malik.
