Wing Construction

September 1
I think I got things a bit out of order.   I'm pretty sure I created the 4 back ribs before I finished the center rib flanging.  It really doesn't matter I suppose.   Either way, they are done.

I used the same method for the back ribs as I have for all of the others.  Create a router template and have at it.  Here's a few pictures for those that would like to see them.

One thing that I did need to do was place a block underneath the form block.  I needed to keep the bolts from sticking up through the form block so the router could make an unobstructed path around the perimeter.

There are only four back ribs, but the form is going to get cut down and used for all of the flap and aileron ribs.  Unless I decide to make dedicated form blocks for each rib.

Here are the back ribs flanged, fluted and with most of the lightening holes drilled.   I needed to purchase a seperate drill bit for the 1.25 hole as the fly cutter couldn't go that small.

tip_rib_router_setup.jpg (58713 bytes) tonight I routed and formed the tip ribs.  To make these ribs I simply used all of the previous router templates I had made and lined them up.  I cut the lightening hole centers using the master form block and lined the holes up with the holes on the templates.  If everything lined up I was good to go.  I was and I did.

tip_rib_one_fluted.jpg (106211 bytes) I like this picture.  Here I have one tip rib flanged but not fluted and one flanged and fluted.  This really illustrates how much fluting does to flatten out the rib.

I finished flanging and fluting the tip ribs today. That was it.  Weekends are going to get tough for the next two months.  My family runs a farm and pumpkin season is our money maker.  Still, I'll try to get some time out there every day.
September 4   Today started out so nice.  I started cutting out the lightening holes on the tip ribs.  I started at the nose and worked my way back.  Apparently I should have gone in the reverse order.  

I managed to cut the first 10 holes without incident.  Then somehow I skipped the pilot hole for hole "E" and instead drilled out the hole in the next spot.  The next spot should have a hole that is .1 inch smaller than the "E" hole.  

This stopped me dead in my tracks.  A nose rib or back rib, hell even a center rib wouldn't be bad.  But to mess up a tip rib.  That's a lot of aluminum in that thing.  

I can only hope that I am still within tolerance and can proceed with my .1 inch bigger hole.  The general thinking so far is that it is still acceptable.  I may give a call to "the bob"  and see what he has to say on the matter.  Unfortunately, Bob doesn't do email, and I generally loathe the phone.  At least until I've met and gauged a person face to face.

My local EAA Chapter 1363 had it's monthly meeting tonight.  I asked the members if they knew of someone/somewhere local that I might find and use an 8 ft brake and shear.  As it turns out right in the Quonset Air Museum where we hold our meetings are all of the tools I'll need.  It pays to ask.

I finished drilling out the holes on the tip ribs tonight.  I also started working on drilling out the jig pin locations on the aileron pocket ribs.

Waaaay back in the beginning of this project I had sanded this template to size.  Tonight I drilled out the jig pin locations and drilled out a number of blanks.  

In the last picture you can see the outline of the backer block I will be using when I start routing the aluminum to size.

routing_aileron_nose_rib.jpg (79474 bytes) I spent last night making more progress with the aileron nose ribs.  I'm trying a different routing method this time.  Since the piece is so small there is not enough area for the hand held router's flange to sit on top of the template.  The bolts holding the assembly together get in the way.  

The solution was to break out my router table.  and run the piece around the router.  This worked well, very well.  I think the remaining pieces will be routed with this method.

September 8-10
I routed out a few more of the aileron nose ribs Friday night.  Saturday, I did little more than open the garage, look at the plans for a bit just to get out there.

Sunday fared a bit better.  I went out there around 8:00 after a day on the farm, and cleaned the work area.  No actual production, but the area is now in much better shape for me to do something.  Tools were put back where they belonged.  Wood and aluminum shavings were swept/vacuumed up.  

Not much progress, but I made a point to at least go out there for a little bit each day.

September 11
Yesterday I finally got myself together and placed my aluminum order.  I ended up ordering most of the Wicks wing aluminum kit and the whole wing steel kit.
September 12
well tonight was just a giant bucket of suck!

I decided to make the routing template for the flap ribs last night.  There I was, merrily working along.  I shaped and sanded it to near perfection.  Just as I was finishing up the sanding and admiring my work.  I noticed that I hadn't bothered to add the rib flange to the template!  

I was done for the night at that point.  I will be using the same template that I used for the back ribs now.  The flange is already there, and the block formed.  I will then cut the flap and aileron ribs to size.  

What a waste of a build night.  grrr   

September 13-17
What a week!  If my life continues at this pace I'm gonna be an old man before I actually complete my plane.

Weds:  I was still kind of steamed about the night before.   Yeah, I know.  I need to get past it and move on.  I'm working on it.

Thurs:  Date night with the Mrs. ,  Dinner and a play.  a wonderful night with Paula.  I did nothing that even remotely resembled working on my project.

Friday:  Today was my 10th wedding anniversary.  Wicks also decided to deliver my aluminum this afternoon.  I now have all the metal I need to finish up my wings. 

I took an early lunch to accept the delivery and spent the afternoon checking the order accuracy.  There were a few errors.  The worst being how the shipper packed the plate steel.  The steel was placed directly on the aluminum and scratched the hell out of it.  I'll need to notify Wicks and see how they want to resolve it

Saturday:  Again another day spent not working on the plane.  I looked at a few items, and finished putting away the aluminum order from Wicks, but no measurable progress.

Sunday: I was supposed to have a lesson today.  Just as I was pulling out of the driveway my cell rang.  It was Adrian, "We have to cancel the lesson, Hotel Victor is in for it's annual."  

I rescheduled for next weekend, and kept upbeat on the phone but WTF?!!  I didn't think annuals snuck up on you.  Maybe I'm wrong but the whole once a year portion of the annual might tip them off.    I scheduled this lesson three - four weeks ago.  Nobody could let me know before 1/2 hour before the lesson. 

 I don't blame Adrian.  He was away on vacation.   I think this was his first morning back.  But I'll bet the owner knew it was going in and was hoping it would be out in time.  Mostly I'm just pissed because it was a perfect morning for a flight.  grrrrr.

With my morning now free, I sat down and wrote an email to Wicks to let them know about the errors and the damage.  The rest of the day was spent walking around on the farm.

Oh yeah, I had a visitor today.  Bill Sheridan a friend from EAA1363 stopped by the farm and allowed me to gave him the "grand tour"  of my shop.  

His reaction?

"It looks so much nicer on the web."

I couldn't help but laugh.  

If anyone else  is ever in the area and wants a tour feel free to stop by.  I'm proof that you don't need a state of the are facility to produce some nice parts.

Wicks came through in grand fashion.  I got a call from them first thing this morning.  

They are sending me a new sheet of .032 aluminum, a three ft length of bar stock I was shorted, plus another length of bar stock to replace a length that had no labeling on it.

A++++ service.  The service person who called me was so nice.  What a pleasure to deal with them.

 

September 19-20
The dog found a Skunk Monday night.  Ben isn't an outside dog but he was designated one for the night.  To say he wasn't happy about his sleeping arrangement is an understatement.  

By 1:30 or so I couldn't take the howling and barking any more.  I went downstairs and sat with him so that the rest of the house could get some sleep.  I went down with the intention to quiet him a bit and then head off to bed again.  I ended up spending the night keeping him quiet.

Since I spent the night up, I went to bed right after Paula woke and slept until 10:00 or so.  Since I wasn't in any shape to go to work I called in and started to plan my strategy for ridding my dog of his stench. 

I tried a commercial cleanser.  No change.

I tried this solution  1 qt. hydrogen peroxide, 1/4 cup baking soda, 1 tsp dish soap.  Success!!

With that accomplished I turned my attention to the BH.

I cut out some .032 center ribs and started routing.  The high-speed bearing seized about half way down the first cut and dug into my form block.    There is a nice divot in the flange area.  I'll hammer the edge and measure. I'm pretty sure the ribs are toast.  

I'll spend some time tomorrow fixing the form block and then route the remaining ribs.

September 22
I had another do nothing night. I did get my replacement material from Wicks.  I put it in the garage, but that's about it.  

I was kind of  beat up from the afternoons activities and wanted nothing more than to lay back in my recliner.   You see, I had gone riding on my dirt bike after work.  All was going along nicely when WHAPPO!  this tree jumped right out in front of me!  Damn trees.

September 23-24
I had no destruction this weekend.  I did have a little bit of progress.

I fixed my router template with some 6 min. epoxy and cut the remaining center .032 center ribs.

I also started drilling the pilot/jig holes in the flap nose rib blanks.

Not a lot of progress, but more than I've been making in the past week or so.

September 25
I drilled and routed the remaining flap nose rib blanks tonight.  Another night with no. . . oopses? 
September 26
pocket_nose_center_ribs.jpg (61420 bytes) cut the remaining flap and aileron pocket and nose rib blanks tonight.  Once I was done with that, I drilled some of the pilot holes in the blanks to ready them for routing.

Here's a group shot of this weeks progress so far

September 27
More drilling tonight.  I finished drilling the pocket ribs and aileron nose ribs.  They are all ready for routing now.
September 28
Tonight I did a bunch of routing.  Aileron pocket ribs and Aileron Nose ribs.  

Since I hadn't made a video in a while I decided to make one of the new routing method I'm using.  (~5 meg)

back, next
