making a sinew bow is not easy,, it is not so much about the tools,, or knowing how to use them,,,, there are things that just cant be measured or explained and have to be learned by experience,, once you learn how to do it,, it is still not easy,, but easier,,
just because you can use a pencil,, does not mean you can draw a portait of someone,, or if you know how to use a brush,, doesnt mean making a painting will be easy ,,,,,etc etc etc etc,,, no its not rocket science,, (for some guys it is) but there is not part of it that is easy,, from the start cutting the right tree( this is not easy), to getting a good even tiller that will perform well for the bow,,,,making a durable bow that has good cast may seem easy,, it can be fun,, but never seemed easy,,even after 30 years of making them,,
