I decided to cut a new bridge for my violin, and I took a few pics so I could do a short write up. It's really not that difficult to do, and (surprisingly) has made quite a difference to the sound and response of the instrument.
The bridge 'blank' is an 'Archetto', and cost about £3-50.
The first thing I did was shape the feet to the belly of the fiddle. I used a craft knife to rough it out, and finished with fine sandpaper taped to the belly of the violin.
The next job was to mark the height of the G and E strings, for which I used a gauge inspired by Kevin Healy's article on FM.
Next I marked out (again following Kevin's advice) and cut and filed the top of the bridge to the correct curve.
The top of the cut bridge was too thick and not even accross the width, so I used a fine file to even it all out to a thickness of about 2.4mm. Then I used fine sandpaper to smooth out any ridges left by the file.
I marked out the positions of the string notches next, then cut them out with a small needle file.
The last photos show the fitted bridge - it sounds great!
EDIT: Sorry, can't seem to get the photos and text lined up properly - is there a way to stop the text wrapping round the pics?
Good job! Although I don't know what I'm talking about. But it does look good. Thank you for sharing!
I had absolutely no idea that it needed grooves for the strings to sit in though, mine just sit on top. Would that affect the sound any?
