Howdy RYoon,
I want to compliment you on your really, fine bow. Great job all around!
Also, it's encouraging to know that a guy can build a decent bow in just a couple of days.
I had recently been thinking a lot about how much time it takes for me to turn one out - too long! So, over this long weekend, I built a kid's bow, from a board, in six or seven hours using just my hand tools; spoke shave mostly. It turned out well. (I'll post it soon.)
Thanks for sharing,
Canoe
(And yes, when are you going to build a bow for the girl friend?)
