Moving knuckles

[Alan McCoy]

Thanks to Eric, Mark, Dale and Fred.

I'll look through the tech archives although the idea of using a table saw
for this gives me the heebee geebees. A router seems slightly less scary,
even if more like a 747 in the shop. Maybe I'll opt for the slower but more
peaceful Wolfley method. I'll let you know how it goes when I get into it.

I appreciate your ideas.

Alan
