Inquiry about possible inaccuracies in plan (adirondack chair)

Plan URL: http://www.yellawood.com/projects/pr...ack-chair.aspx

This is my first project, so please go easy on me lol. I'm questioning the measurements for the top center point on piece F (called "Seat back support detail"). The plan says the center top point of the back support is 15 5/8" This can't be right.

If I measure in 5 3/4" (where the arch starts) and again out to 27 1/2" (where the arch ends) shouldn't my center point be around 16 5/8"??

27.5 - 5.75 = 21.75 (horizontal length of the arch)
21.75 / 2 = 10.875 (center point of arch)

So adding the straight edge back (5.75") plus the arch center point (10.875") puts me at 16.625" or 16 5/8"

Your math is correct. It appears to be a typo in the plan.

What I get if you keep it symmetrical the 27 1/2" should be 25 1/2". If the 15 5/8" is the center of the arch and you subtract 5 3/4" it should have the overall arch as 19 3/4" wide and then if you add 5 3/4" to the side it comes to 25 1/2". I'm just looking at this one part and not the overall project. You might lay the thing out on a stick of wood and see how it jives with the rest of the parts. There is something wrong. It would help if they gave a dimension of the space between the two arches. Then if you add up the small end of "L" 6 pieces 2 1/4" wide with 1/4" space between it would add up to 14 3/4". What is to be done with the extra 7/8" to 1 7/8". I'm wondering if these plans were never proven by actually building the bench.

If the 27 1/2" is correct and the 5 3/4" is correct then the 15 5/8" would be 16 5/8" like your math shows.

Being my first project, it's a little discouraging to find these errors...

Online plans often need to be fixed because of similar reasons. It's just one of the things you get with free plans.

Maybe that is something we need to get going here. Have a forum here where a person could submit their plans and after a while after some folks build the project and it is proven and got the bugs worked out delete the chit chat and lock the thread.
