Would it be out of line to ask someone to post a Bill of materials for the XL? I'm nearly sold on the design but would like to crunch some numbers before I pull the trigger.

The Materials List is located in the Eaglersnests Yahoo Group [Files] here: https://groups.yahoo.com/neo/groups/EaglersNests/files/-XL%20/Materials%20Information/

Thank you Sir. I didnt think to look there, I thought everthing had migrated here.

New member here. I tried to access the Yahoo link but even after I signed in with my email, it said I had to be a member of the group to see the B.O.M.
Any tricks to this?
Cheers,
Cody

No tricks, you have to join the group...

What I meant was, how do I join. I saw no button or link saying "request membership" or "join" or whatever.
Thanks,
Cody

Cody,
You have been sent an invitation...

Thanks Sir.

Thank you again to this group. I have recently purchased XL plans (shipping in process) and was looking for a BOM to work up a budget.

How do you get the invite? Just purchased plans for lexl. Should compliment my de nicely !!

You don't need an invite. You do need a yahoo account. (a yahoo email address)
You technically can join a Yahoo group without a yahoo account, but you will only be on the mailing list --you would not be able to see the files, photos, etc.
This will do you no good with this particular yahoo group because it does not send out group emails.
If you have a yahoo account you should see a "join this group" button in the upper right on the group page. I.E. here:
https://groups.yahoo.com/neo/groups/EaglersNests/info (https://groups.yahoo.com/neo/groups/EaglersNests/info)
Just mention you are a member @ eaglers nest forum...
Here is a blow, by blow on how to do it...

Since this an XL BOM thread, I ordered the Aluminum for the Tail Feathers, but in the plans I now see that there are c-channels used for the ribs, there is no list for it in the BOM, How would I know what size and how much to get? it just says 1/4"xFIT not sure what width to get and length, also is 1/4" tall enough, that's the area the gussets rivet to.
I need to get it, I though I was ready to start on them this weekend, what a feeling thinking and planning to work on it and not have all the material on hand.

check your drawings; I think you will find these channels are different sizes on each end.
Like on the elevator 3/4 inch at the hinge and 3/8 inch at the trailing edge. They are tapers. you get to make them or have them made. They come from 0.020 alum sheet.
While I am sure that comes as unwelcome surprise number 2; there is a lot of work getting the tubing happy and you need that before you really can determine the exact lengths
Each piece is slightly different as a long one tapers slower than a short one. We will call this one number 3 . Some probably ignore number 3 and get away with a slightly bad fit.
Sorry to bring in the bad news but it is what it is.

Other areas of the tail feathers have other tube sizes. There is no common size.

Aprox, what size sheet are we looking at?

Joe, what are you meaning "size of sheet" ?
There are fellows telling you that these ribs or channels are on the plans and that they are 3/4" on one end, and 3/8's inch on the other end. And as Tom nicely stated, each one is different in length due to the changing shape of your leading edge and trailing edge. Am not sure what was meant by bad news.. But back to the ribs, Many-many aircraft tail feathers are/were built this way.
AS for sheet, I don't know what your meaning. as it is called out in the plans for material and thickness.
Best of success.

well looks like i have to cut strips from 0.02" material and use a brake to make them, so was wondering what size sheet to get. Unless others have an alternative.

Ok, now see what your talking about.
That is certainly a depends question, mostly depending on if it sheared to a line and then that line works for the next one. Or if it is cut out each piece with the corresponding waste. So I don't think anyone will commit to that answer. With your CNC ability this would be easy for you to lay out each, (depending on your cutting/piece method) and then you can share what you come up with, or at least one worked for you.
As you know this is easy to draw out..
How I draw such:
form square box on the longest axis of your longest rib.
draw your two lines with min and max distance (width and length) at ends.
draw your next rib (hopefully using this just made cut line) and Z them back and forth for min. waste.
Your flanges will all be the same, so only length varies.
Then you can estimate at the same time all of your gussets required for this... pretty soon you have your
"sheet size"

I wanted to order a bunch of adel clamps and wondering which ones people are using there is a DG and a WDG i believe. I want to get a few 1/2" and a bunch of 5/8".
