Edge Finding For Newbies

[Phil Gravett]

Traditional tool makers used a sticky pin. This is a dressmaking pin held in a bit of plastacine (blue tac or chewing gum works but not as good) put on the cutter or drill. With spindle running, you press on side of tip of pin till it runs true. This could be done with a lolly stick or something like. You now have a fine point that is true with centre of cutter and can be lined up with edges, scribed lines and centre dots/pops.
A wobbler set is a sophisticated version but although I use a set on lathes and mill I have always found a "Sticky Pin" most useful and quick. Wobblers are useful for edge finding but you do need height.
