Lower Wings are Skinned!

We finished up installing the lower wing leading edges, wing tips, hinges and bell cranks. As Dave pointed out, it is nice installing stuff for the final time. Next step is the aileron coves and these babies will be ready for cover.

I apologize for not having any pictures, I did take them but my POC Motorola Droid 3 wont let me retrieve the pics. Ugh I hate Motorola and phone contracts. Pics to come.


Right Wing 80% Done

So the right wing leading edge and wing tip are all glued up, the hinges and bell cranks are all installed and the wing is taking shape nicely. Check out the pics.

Lower Wing Attach Points are Tacked

Posted in Bottom Wing, Fuselage, Super Stinker X with tags , , , , , , , on May 9, 2010 by mars58

Well Today – 5/8/10 – was a good day. We have had the lower wings at Dave’s shop and we have been working on getting them nice and strait with the fuselage. The first fit showed about 1/8th of an inch tight on the rear left side and an 1/8th of an inch loose on the right rear wing attach fitting. So we tacked the front fittings and started looking for the 1/8th of an inch. Finally we noticed the one bay on the fuselage is about an 1/8th off center to the left. Thus making up our discrepancy. So we decided to widen the bend on the left side attach bracket slightly to take up the 1/8th. On the right side we cut out a new lower attach fitting that would give us the extra 1/8th once bent up. So today we finally got everything fitting perfectly. Wing strait up front and even distance from tail post to wing tip.

We also drilled the lower wings for the landing wire attach pin, and cut and drilled the 1/2 inch solid stock for the aileron hinges. So after about a month off, due to work and things we have made some good progress.

Drag Wires In Lower Wing – Cabanes Taking Shape

Posted in Fuselage, Super Stinker X with tags , , , , , , , , , on March 24, 2010 by mars58

Last Tuesday we installed the lower wing drag wires and tightened them up. I’ll have some pics of them soon.

Wednesday Dave and I got together to figure out how we were going to hang the Cabanes.

The Cabanes hold the upper wing in place via two bolts that go through two inch long tubes that sit on top of the cabanes.

Full Jig

The plans give the dimensions based on how high and far apart these two tubes need to be to set he correct angle of the top wing and position it correctly on the fuselage. So in essence we need to put these two small tubes in place and build the cabanes around them while keeping everything centered and even.

So we kicked around a few ways to jig these up. The plans center the forward tube (forward spar attach point) on our zero reference line that drops from an imaginary point in the sky, through the center of the tube, down through the lower center engine mount attach point on the fuselage. The tube is also spec’d out 18 and 3/4 inches above the top, forward fuselage cross tube. The second tube for the rear spar attach point, is 19 1/2 inches rearward from the center of the forward tube or spar attach point and 17 3/4 inches above the next rearward fuselage cross member.

Complete Jig

We didn’t want to use wood to build the jig, because there is just to much flex with wood to get it right. So Dave came up with a nice piece of aluminum square tubing. Because the firewall is slanted back at the top, the top tube is actually 5 inches behind our zero line. So we decided to cut a piece of the square tube that would run from bottom engine mount strait up and hold the first fitting. This posed a problem because of the slanted firewall. We solved this by running a piece of the square tube across the two front fuselage cross members and we made it extend 5 inches from the front and hold the vertical tube at the zero line. We notched the horizontal square tube to fit over the fuselage cross members so it would lock in place and give us a nice sturdy base.

From this we added a riser on the rear for the rearward spar fitting. We had drilled bother risers and put a threaded rod through the holes that we slid the small tubes onto and locked in place with jam nuts. With that in place all we would have to do is measure, cut and fit the streamlined tubing, then tack it in place.

This is a picture of the rear, two inch tubes and the first cabane strut tacked in place.

Lower Wing Attach Angles In Place On The Right Wing

Posted in Bottom Wing, Super Stinker X with tags , , , , , on January 10, 2010 by mars58

Saturday 1/9/10, we cut and drilled the right lower wing attach angles and bolted the attach points together. We also finished the spar caps on the top of the spars.

Bending Up the Wing Attach Fittings

Posted in Bottom Wing, Fuselage, Super Stinker X with tags , , , , , on December 11, 2009 by mars58

We Started bending up the Kimball fittings so we can weld them to the fuselage. Dave made a bending jig to keep the size exact. The Kimball Fittings are great!! Between the laser cut fittings and the Cartesian frame kit things are really moving along with the fuselage. It’s time to get cranking on the control system.
