Adjuster Screw in Galbert / Manney Reamer
Hello,
I hoping to begin making a tapered reamer along the design of Richard Starr / John Alexander - further refined by Galbert / Manney. The one area I'm unsure of, at this point, is the adjuster screw. Can anyone enlighten me as to what type of screw it is? What exactly it does? (Does it's point simply press against the top of the saw blade and when turned push it lower down?) And how , what angle, pilot hole, etc. the hole is cut for the screw?
Any and all advice & information much appreciated. Thanks. Paul
