Kerfing, notched side in or out?
May 5th, 2007 at 1:41pm
 
I've seen kerfing installed both ways: with the notches facing out and notches faces in.  The Hana Lima manual shows it installed with notches facing out, but notches facing in looks a lot neater in MHO.

They do provide some stiffening effect for the side bends but mainly are for gluing surface to attach the top and back so it doesn't really matter which way they go.

hey guys:

Kerfing is for 2 purposes...added gluing surface to the sides and top and bottom plates. And den for support when adding bindings/purflins to the edges.

if no more kerfing...and you bend your sides thin....and you like bind....when routing...most likely you will seperate the sides from the plate surface you are routing and experience a rapid heartbeat and a real bummer!This happened to me at a demonstration for binding....so sad! Took me a mnoth to repair the damage I made to sides and top!

Guys that add purflins with their binding need the kerfing reenforcement since the added purflin veneer colors make that step cut in the top plate wide..sometime almost 3/16th in from the edges of your sides....so way fatter than the actual sides...need that extra kerf support or it will separate.

Whether to place kerfings in or slots out....really doesnt matter....looks clean with kerf slots in...but for those who shape kerf lining, angled or round...that looks way cool too...so show the kerfs out!   laters  ukeman
