Noooo! You are not ready for wings yet. First you have to put the hint on the trim tab, then you have to roll the leading edges. I was hoping you would have done this so I could copy! I am procrastinating!

Hi TK,


Ha...!!!

As you may know, all these fine aircraft parts will be shipped across the big pond to Québec in due time... I prefer leaving the leading edges as is for transport and roll them after the inside inspection...

As to your procrastination, it can be a good thing sometimes... I do it often...
But you'll have to procrastinate a long time while I do my slow build wings as you have the QB!!!

Default Empennage (almost) done

Finally, after getting the replacement stiffeners, they were cut to the correct lenght , prepared, primed and installed.



The left elevator was closed and hung with the other tail parts.
No more will be done on these until the MD-RA inspection!!!

Default Wings started !!

So, 5 days after my birthday, I went to the airport cargo area.
These were waiting for me!!
OK, how to get these in the van???
The long box is 4.70 metres (15' 5")


When the need arises, one finds a way!!!
I only had to drive 5 kilometres (3 miles) to get to my airplane factory.


Brilliant packaging as everything inside was intact despite obvious abuse on the crates. I'm glad I chose air freight. I heard horror stories about maritime shipment...

Inventory was done and unfortunately, there's one small glitch. I got 4 of the same part instead of 2 left and 2 right.


The wing stand is built. On wheels of course because of the restrained space.


The spars are a beautiful sight for the eyes. Too bad they will not be seen when the wings are done.


After careful studies of the plan, (one does not want to goof on these...!!!) work is officially started!!
Platenut rivet holes are drilled to size and 2 are countersunk.
A rivet is used to check the depth, all looks good.


Holes are then countersunked and spot primed. Underneath, the debbured holes are also primed.




Platenuts are done on one flange of the left main spar!!! 3 flanges to go!!!


I really love doing this !!!

Default December Update

Work continues on the wing kit.

Hint: put some tape to cover the crack between the main spar flanges and its doublers. It prevents alu shavings from getting stuck in there.
Ask me why I know!!


After the 144 platenuts on the flanges and the 4 on the spar are done, time to attack the tie-down bracket parts. The 2 spacers are made from a bar of alu. The main body is tapped to accept the tie-down bolt.




All is bolted to the spar, with the aileron hinge brackets in the back.



Next up are the rear spars, and it's pretty straightforward. Time to get those edges nice and smooth!!


Lots of hole drilling and deburring...


Once primed, time for riveting. I'm glad all rivets were possible to do with the squeezer. The only trick here is to leave the correct holes free for further riveting of the ribs and other stuff.


Ok, here comes hole and edge finishing, flange squaring and fluting for 40 or so ribs, (not counting the tanks) before clecoing, drilling, deburring, priming and riveting to the spars...


I guess I won't post again in 2012...!!! ahahah

May everyone have a great holiday season !!!


Cheers !!!

Default Back to work!!

Back to work on, then off, then on the wings again...

On the wings: Ribs now all squared, fluted, drilled for electrical conduit, and deburred.


Then mounted on spars to final drill.
Starting to look good!!!


Then I had a solo discussion about Proseal...
The expiry date is 04/13. Four months away.
Will I have enough time to finish the wings and skins before?
Maybe not, so I better start on the tanks...
Can I do the tanks before the wings?
Some say yes, some say it's better if done after for tank and leading edge alignment...
So I decided Go with the tanks.

Tank instructions start by drilling holes "perfectly centered" in the Z brackets.
I did my best to do them Perfectomundo centered but obviously it wasn't good enough... A few are "OK", but some not, and this one is the worst:


My hole was off to the left, couldn't get the cleco and the tank baffle to agree.
I drilled through the baffle and even it was off-centre...

Lessons learned: I might not be precise enough in my drilling or maybe the instructions should be changed, so I will not repeat this way of doing the Z's.
I believe the 1/8" holes should be drilled AFTER the Z's are bolted to the spar.

Sadly, I read this post only AFTER:
http://www.vansairforce.com/communit...ad.php?t=93916

I will follow this method next time!!!
http://www.rv7factory.com/log/060108.php

So new Z's, platenuts and bolts are ordered.

Meanwhile, back working on the wings, I don't stress too much about the Proseal since my shop is nicely refrigerated most of the time and it should keep the Proseal OK.

Default February progress

One other thing I learned and that I can share here is to not rivet with a gun if the parts are not as stable as possible.

I tried to rivet the main wing ribs on the spar while it was on the wing stand.
Even if the spar is solidly attached, not moving and I put extra hand/arm pressure on the gun to the rivet to ensure a good contact, this was the result:


"Exploded" manufactured heads...

I can say that I'm now a very good rivet remover because I must of bucked and removed at least 12-15 rivets before calling it quits, go home, and sleep on it.

The next day, frustrated, thinking my riveting technic went out the window or that I had a "bad" batch of rivets, or a defective rivet cup and looking for a solution, I "practiced" riveting a lone rivet on a scrap piece of alu. All was perfect!!! Then it struck me: the wing stand...

It tend to think that when the spar is on the wing stand, it can vibrate ever so slightly when the rivet gun is in action. Thus the above outcome.

I then moved the spar to the work bench and, magic!!!


So the work continues:


And the wing spars and ribs are back on the stand:


The skin and cleco festival with the drilling that follows.
I counted 1380 holes for skins and leading edge...


On to the tanks. I received my new Z's and drilled the root bracket off centre by 1/16" away from the flange for more wrench space. The other 6 were drilled 1/16" towards the flange for more Pop rivet tool space.


No 1/8" holes are yet drilled on the Z's.
They are squared, bolted through the lone hole and clamped to the spar to drill the other 2 holes.



The tank is pushed as much as possible against the leading edge and pushed down on the spar and secured in place.


Drill the root Z as it's the only one exposed at this time.
Then, the leading edge is removed to expose the tip Z drilling.
Protect the spar with a scrap piece of alu.

Default Tanks continued...

Then remove the tank skin and inside ribs, leaving the end ribs and baffle on the spar.


Make sure to use a good drill stop and drill the Z's through the baffle.
Perfectly drilled Z's and positionned tank!!!



This way of doing the Z's is straightforward and can't go wrong!!!
