Not trying to be the A hole.
It's not that simple.
What kind of bow do you like, Bear, Damon Howatt, Black Widow ,someone on this Forum??
A lot of bow shooters like 50's stile recurves like a Damon Howatt Hunter. You could buy one, strip it down to bear glass, add some masking tape, mark lines every 1" and measure the thickness every 1" and log it down and find the taper rate, The taper rate could be .005 coming off the riser and change to .002 after 5/6/7", Or it could be .003 or .001, I've done it, I like it , so that is what I build.
Kenny M has a R/D design that shoots quite, He will fix you up with everything you need, Binghams also but they are shutting down. Very few prints to buy for build bows out there for sale and some just trying to make money.
Some of use chase speed, THAT'S the rabbit hole that can drive you crazy. And some just like the design/look of the bow.
There is not a "This is the way to do it"
It's fun to build them for a hobby, but it's getting high in $$ to do so.
You just have to start somewhere and Maybe end up where you want in a few 5/6/7 years.
This one is a .005 coming off the riser for 7" and then .002 out to the nock, no tip wedge, but a 4" underlay, the .005 push the bend out some and helps the recurve open up some, the bigger the radius, the more it will open up, the smaller the radius the less it will open up.
