I'll have to go through my receipts and compile a list.

That makes a lot of sense to me. Will save $$$ on shipping.
Please share your order with the group, so it is in the archives for future builders.

So Doug,

Yes you are correct I misunderstood his needs for mine
I am trying to wrap my head around what wood I want to order as well. I am thinking of ordering all the wood needed for the wings except the spars and order them when I am ready to assemble the wings.
Later!!

True, how efficient a person is at laying out parts on plywood and how much waste material they generate also figures into the calculation.

Sorry for the misunderstanding. Orchardair was asking about build ribs. The information that I provide was enough (for me) to build 40 ribs, period. No center section, wing walk, false nose ribs, leading edges, spar doublers, etc. Also keep in mind that material list will vary from builder to builder, as each decides on their material of choice. Example: Hans and Sam are building a beautiful Hatz in Europe, but their material lists includes Okume (spelling?) wood, for their leading edge, that apparently is available locally.

TulBiplane,
I am curious as to what you were able to build with that amount of wood? Did you take in account sheeting the end rib at the aielron bay as well? Also did you have enough to build the top wing center section? What I am looking for is to order all the ply necessary to build the wings not just the ribs. So that would be the spar doubler plates, supports/reinforcements etc: The shipping is expensive on the ply so I want to make sure I get it all ordered at the same time.
Thanks!!

Where are you ordering your wood from? Aircraft Spruce? Wicks?

Still researching, one is cheaper on spruce and the other cheaper on the ply. I will have to see how it works out with shipping. I am also waiting to see if my buddy is going to build as well, we are meeting to discuss this during lunch this week.
Later!!

I ended up ordering 510 feet 1/4 sq spruce. I have more than 10 feet left over, but not much.
1/16 Mahogany? I think you are overkilling. (2)1/16"x2'x4' ply for gussets did all of the ribs for me. Later, I rebuilt the #1 rib for the top wing and skinned it with 1/16 Mahogany, which required me to order another 2'x4' sheet.
1/4 Ply? I started with a 4 x 8 sheet and still have quite a bit left over.
I also bought locally a 4 x 8 sheet of MDF. I used it for router templates and various other needs. Amazing stuff.
T-88 epoxy was also purchased locally.

Remember, it is not an airplane, but a journey. Hope this helps.

Thanks Anthony, that helps.
