Who needs expensive brass and rosewood to get to the middle of those dowels and chunks of turning stock when all you need is a piece of scrap 1/2×3/4 stick and a BORG paint stir stick?
…the handsawgeek Poor Man’s Center Finder !!!
The only thing to be diligent with here is that the marking edge is straight and that all the relative angles of the bearing surfaces and ‘blade’ are laid out as accurately as possible.
It might also be wise to slap a quick finish on this (unlike mine) to distinguish it from other pieces of scrap wood when you’re cleaning up your bench.
Oh, and I would not recommend using a marking knife with this particular version…..
