Title: Board bow thickness and width
Post by: Wolftrail on January 18, 2018, 02:58:00 PM

Building a simple maple board bow, backed with a 1/8" lam of maple.  Its 7/16"+ thickness and 1 3/8" at the fades how long should I make it to achieve 42#.   I like to keep it  around 65-66" NTN.

Thats what I thought as well,  2nd. and 3rd. opinion confirms that.

After a bunch of errors, I'd start long & tiller it to whatever it comes out being.  Then, if it's too heavy, you can use a pocket knife to gently scrape away a little extra material & bring the weight down.  And if it's too light, you can shorten it a bit.  I'm pretty new at this so I like to find ways that I can correct a mistake later rather than plan on getting it right the first time (because I rarely do).
