So when I first brought my fiddle down from its 25 year-or-so stay in the attic, the bridge was bent over like a dog's hind leg, so I fitted a cheap bridge (from Amazon) and just copied the shape of the old one. I made one or two errors with the string slots (by copying the errors from the originally fitted bridge!) and while I've got the strings off to fit my FM set, I thought I'd cut a new bridge (I have a blank).
My question is, how critical is the string height at the end of the fingerboard and do I need to worry whether it's G string 5.5mm and E string 3.5mm (as I've seen online elsewhere) or G string 3/16" and E string 1/8" (as per Kevin Healy's article on FM here - https://fiddlerman.com/2011/11.....n-m-healy/). I'm not sure if the difference from metric to imperial measurements are worth worrying about or not.
I'm making a gauge to mark the bridge off and it would be nice to get it as close to theoretically correct as I can.
Here's a couple of pics of the new bridge and my gauge - sorry the pics are a bit poor quality, I just took them on my phone.
Jim, I used the information on http://www.violinresearch.com to shape the bridge I put on my fiddle he shows not only string heights but how and where to thin the blank for a better sound it worked for me string heights were G .197 or 5mm. D .170 or 4.3mm. A .146 of 3.7 mm. E .118 or 3 mm. I measured from the bottom of the string to finger board. Thats a 41.5 mm deg. Radius Mark
