I'm sure there are as many different ways to build ribs as there arebuilders but here's the way I did it:I didn't worry about letting the epoxy (T-88) stick the rib to the jigbecuase it wasn't in there long enough. I assembled, nailed on one side ofthe gussets, and removed the rib from the jig. Becuase I hate nailing(which actually isn't bad with a small ball-peen hammer and needle nosepliers), I didn't nail the gussets on the other side. I used those blackbinder clips, you know, paper clips on steriods, and clamped the remaininggussets.Making your own jig is a easy thing to do. I used 3/4" plywood, some scrapcapstrip stock, and staples. One thing I built that helped me was atemplate of the rib profile. I made that out of a thin piece of plywood.It becomes more handy than the rib drawing as you can use it to trace theoutline on the jig, use it as a pattern for pattern-routing, and smack thecat that's sleeping on your workbench.Robert HainesMurphysboro, Illinois******Kip, Another good rib jig material is lexan, like from Home Depot. Gluedoesn'tstick to it, and if you drill a hole under each joint, you can pop the ribsoffwith a piece of wood dowel.Cheers,Warren.******________________________________________________________________________________Subject: Pietenpol-List: Re:Wing Rib Jig request

08/30/2001 10:21:30 AMList,Thanks for the replys re my request for a rib jig. I wasn't so muchconcerned about building one myself, it's just that conservationist that Iam, I figured why use materials to make a new one when someone out theremust be done with theirs?Anyway, it sounds like everyone seems to think this is a very personal kindof issue, so I guess I'll be digesting all the advice, as well asBingelis's information (what a gold mine those books are - thanks againChris!) and making my own.I liked the Lexan idea, but then Robert's comment about not leaving ribs inthe jig long enough to set up & stick makes some sense too. Those binderclips ARE useful, I use 'em all the time around my shop & lab for clampinglittle pieces for gluing.Cheers!Kip Gardner (who just passed the buyer's house inspection - one more stepdone)Laboratory ManagerOld Dominion UniversityDept. of Ocean, Earth & Atmos.

KipIt is fun building ribs, a lesson in patience too! I might suggest a trickfor holding and starting those little nails. Find a clip for the end ofmulti-meter leads, the kind that uses a little J shaped hook operated by apush button to grip the wire. With this your dumb hand needs to worry less!another trick to speed things up is to toss a handful of nails on a slopedcookie sheet lined with paper. Tap the sheet while inclined slightly and thenails will align themselves head down. Makes picking them up much easier.J Mc----- Original Message -----

I did all my rib making , and all nailing, for that matter, with a good oldfashioned tacking hammer. The kind with the two long snouts, with a magnetat one end. Using the inclined cookie sheet, or like I used, a piece of plyon an angle, you'd always pick them from the same angle, start them with atap, flip the head and drive them home. After a while it was very easy toget good at it.As far as rib making.....just my opinion...I covered the jig board withplastic sheeting , that T88 doesn't stick to, and made a rib per day. thenext day, pop it out and put the gussets on the other side while you make anew first side. My feeling is that the jig board hold things really tight,and precise. Didn't feel right moving the whole rib when it was wet.Did you ever look down a wing where the ribs weren't the same? Lookscheesey.What's wrong with making a rib a day? One month to make all the ribs forthe Piet. I usually made the rib first when I went to the workshop,boiled the water, soaked the ribcaps while I was cutting the pieces, thenmade the rib. Whole process took maybe 45 min to an hour. Then on to theproject. Worked great.walt---------------------------------------------------------- Original Message -----

As for communications, I already have my light gun ready for installation. Still need that dang mixture fitting so I won't polute the air.More info on the trip laterCorky in La making plans to fly somewhere.________________________________________________________________________________
