Postby planecrazzzy » Sat Nov 10, 2007 7:24 pm

Hey Guys,
               Just posting some pictures of my Rib Jig....

I'm waiting for glue to dry.....I screwed up one hole  ( the LAST one )

I put some glue on a few toothpicks and tapped them into the hole....

"My" version of a rib jig ....has 3/16" holes drilled , w/ 3/16" Stainless Steel Pegs.....

The holes go "Through" the board ....Just incase I need to move them to remove the rib....

I put the pegs where I thought they would be needed , If I have to , I can add more...

Make a note....After cutting the "rib print" to "piece it together".....Use the "match lines" but also use the "cord line" .....it helps get it a little more accurate...

                                Gotta Fly...

Rib Jig / Buttercup

Postby planecrazzzy » Sat Nov 10, 2007 7:25 pm

      WARNING :

I'm posting a picture that shows a flaw in the Quality of the print...

If you look down the bottom "Cap Strip" you see how the line is wavy....

This screwed "my" ribs up.... I didn't notice it until I was done....

I hit the "waves" just WRONG in that area , and I have a flat spot on all my ribs...

 (  3 of those pegs are "inline" )

          Check yours , I don't think Earl's changing it...

West Systems Epoxy

Postby planecrazzzy » Thu Nov 15, 2007 9:38 pm

Update on Progress....

I "primed" my West System "measuring pumps"

and I gave a Squirt of Resin & Hardener in a plastic container....

It was too much for my glue job....( I'll have to watch that )

After I glued everything , I brought it into the house.....

70 degrees is a better curing temperture

There's no smell to the stuff...

I had put pieces of wax paper around all the glue joints....

I'm gonna put a full sheet of wax paper on the next one , I'll cut out where the pegs are...

Ribs

Postby planecrazzzy » Sat Nov 17, 2007 4:03 pm

Got a few more Pictures...

The wax paper is working GREAT....

I didn't put a full sheet on the jig , But I have better coverage than using

all those little pieces...

I tried a few different ways to git the Wax Paper over the pins...

what worked was marking them with a "sharpie" , then melting holes w/ soldering Iron...

It made a good fit...

Full Sized Ribs

Postby planecrazzzy » Sat Nov 24, 2007 7:53 am

Hey Guys,
               Moving along, the 14 ribs ( 3/4 ) are all out of the Jig....Time to make some Full Size Ribs...

I added the Blueprint ( Leading Edge )  to the Jig....and Drill and added Stainless Pegs...

The bend is a little too much....So I wet the wood , and clamped it in a position to dry....

Hoping this will pre bend the cap strips enough for a good fit....

Oh,  I sorted through the wood a little , to find some pieces that bend easier....( some are pretty Stiff )

Here's some pictures...

Full Sized Ribs

Postby planecrazzzy » Sat Nov 24, 2007 3:53 pm

Pre-bending  the Ribs that way,  Wasn't good enough.....

I ended up soaking the ends in Hot water for about 20 minutes....Then put them in the Jig....

That seemed to work....

Picture time...

Good looking ribs.  What kind of epoxy are you using?  T88?

Epoxy

Postby planecrazzzy » Tue Nov 27, 2007 7:15 pm


Hi Sean,
            It took longer than I planned to get started on my next plane....

But it's moving along now.... ( Cash & Time )

The Epoxy is West Systems.....I think Resin 105 ,  Then I got the Fast cure hardener 205 (?)

It sez fast cure.....But their talking around 9 hours....

   Got the Garage heating up right now.....Ready to jig up another "full rib"  ( only 4 of them total )

Have you read the "Steve Wittman" story that I posted in this Wittman section....You should....good story...good guy !

Full Sized Ribs

Postby planecrazzzy » Fri Dec 07, 2007 10:21 pm

I got a little further with the Full ribs....

I've got the Mohogany epoxied on the one side.....I used alot of weights and it
laminated real good....

Before I put the ply on the other side....I drilled some holes where the spar goes...
That'll help me when I start to cut out the plywood in that area....

Then I trimmed up the plywood on the rib , so I'll be able to see where to trim the
other side.... Trimming both sides at the same time would be hard to do....

When I put the plywood on the other side , I'll coat "everything" inside the rib with
the epoxy....I have a bunch of disposable acid brushes....

Here's some pictures...

Glad your there to "bump" the "allowed size"   for posting pictures....

Router Bit

Postby planecrazzzy » Tue Dec 11, 2007 8:25 pm

I was told a little trick to clean up the plywood around my Full Ribs.... It's a Router bit with a roller bearing...
and it cuts "flush"...

Wow , it's fast , and does a great job.... Although , I clean the corners with an Exacto blade....
