i-j-c Posted January 17, 2005 Report Share Posted January 17, 2005 OK..a two part post. 1. When I used to make guitars many years ago...the biggest problem I had was making a radius on the fingerboard. In the end I made my own kind of jig/tool...which works perfectly. I still have these tools today.. Anyway...I made it using hardened steel...I had a radius cut in the steel by my father - and two locating holes taken from where I wanted them on a block of wood...I then cut a slot in the block and inserted the steel scraper...and screwed in place...I did it this way for easy removal for sharpening. The centre point on the radius sat at the flat of the block of wood. The reason for this was simple...so when I had cut down the radius...I knew I was done..because the block of wood would then be sliding on the fingerboard surface...and would no longer cut. The tool was used by moving it back and forth along the length of the fingerboard...it always came out leve...as when the block of wood touched the surface...and high spots would by taken down until it cut no mre...so everytime I had a perfectly level fingerboard...a diagram below is included. I have 10 blocks ranging from radius 12" to 22"...they were perfectly simple...and because it was tempered hard steel..it could cut anything..ebony, maple you name it...it also reduced the need for much sanding...here is a diagram which explains it better: This leads me onto the second part. On my two projects I am starting I want a compound radius...I intend getting a blank...and starting with the tighter radius work my way down the fingerboard...but I am nt sure how this will work as I am concerned about too much taper off at the end.. Any of you know any decent tips for compounding...I know you can get these ready made from stewmac...but as always, I like to experiment and do completely myself...
