Not much was accomplished today, but i did get the 3D printed bulges positioned and glued onto the wings.

Got home early today and while waiting on the Ups truck, i glassed the bottom of the wing center section:





Then a few hours later, the Ups truck showed up with these goodies:

After dinner i snuck away for about 20 minutes and dry assembled the rudder parts. All of the parts are cut from 1/8" ply and all slots are sized for 3/32" ply. I did these assemblies on the assumption of getting 3/32 ply, but apparently thats not available in lite ply, so 1/8 was substituted. At first i had plans to resize all the slots to 1/8, but being able to sand the slots and get a nice snug fit is beneficial i think. Plus it only took about 10 minuts to size all of the rudder slots.


Dry fit rudder structure on the skin:





Rudder assembly jig dry fit:





All the parts laid out. There are 24 parts in just the rudder assembly (including the jig parts), i started to count all of the parts, but there are well over 100 im sure.

Nice work , what is the thickness of the parts ?

My Feedback: (23)

1/32, 1/8 and 1/4

I cut the G10 horns out on the cnc router and started laying out the ailerons for construction. I need to get the ailerons close to done so i can trim the gap seals to size on the outer wing panels so those can be glassed.

Dinner is over and the kids are in bed, so i snuck back out to the shop for 20 minutes.


Here is the first aileron on its way to being glued together.








You can see the 1/8" carbon tube installed. I dont have the plastic hinge bearing tubes yet, so the upper skin cant go on, i also expect to have to adjust the rib heights towards the tip as they are a bit to tall. You'll also notice the square balsa TE that runs the full span. These parts (3 per aileron) were going to be laser cut, but i mistakenly forgot to put them in the cut files, which has been corrected.


Here is what it will look like with the top skin on:





And here you can see the notch in the construction jig that allows the aileron horn to be installed during construction:

Impressive Thomas.

Must be fulfilling to cad draw, turn in to cut files, send off for cutting, get back and presto wamo precision assembly.
I will be watching the Rhino tutorial closely. Would love to do this stuff.

Yea its kinda cool knowing you did an interlocking assembly on your own. You can really build this whole thing without a drop of glue which is really cool.

So i got the upper and lower wing skins trimmed to the correct shape and then capped the opening.





The wingtip blocks were then glued on and shaped:





I also got one of the ailerons partially framed up:

Bottom surface of the outer panels are glassed and he upper surface of the center section is as well. The AC is off in the shop, so fhis evening i should be able to trime and glass the top of the outer panels and then the end ribs of the wing center section.

The wing panels are now completely glassed and trimmed. I'll rol a coat of primer on these things tomorrow... Hopefully.

how many coats of resin do you put on the wing before you prime? Do you feel the weave with resin or do you do like some (not me) and use the primer as a filler?

invertmast

My Feedback: (23)

One application of un-thinned resin and i use peel ply. A second coat of resin only adds weight, the weave of a cloth under 1.5oz should be filled with one coat of unthinned resin. Im using 3.2oz glass on these wings as they are only for plugs and the increased stiffness from the thicker glass is desireable.

With a coat of rolled on primer, 90% of the surface imperfections are filled and 100% of the pinholes get filled.

Makes sense in this case.

My Feedback: (23)

Two coats of primer on the top. After my sons dentist appt and grocery shopping, ill roll the bottom.

Tom, what's that primer you are rolling on? Thanks, Dan.

My Feedback: (23)

Ill post a photo later.

My Feedback: (23)

Bottom is all primed.. Tomorrow, work permitting, sanding!

invertmast

My Feedback: (23)

Heres the primer im using:

invertmast

My Feedback: (23)

Lots of sanding today. I need to tighten up the wing panel seems and the center section to fuse fillet and panel line layouts can start in prep for lithoplate detailing.

invertmast

My Feedback: (23)

Alright!! All the body work and sanding is done on the wings!


Heres the last little bit getting the wing to fuselage fit nice and tight:








I then did the panel line layout on the top of the entire wing. I'll do the bottom tonight when the kids go to bed:








These are nice big panels, so cutting them out wont take much time at all. But there are A LOT of rivets on this wing, which will take awhile.
