As I stand here with fabric and Polyfiber Chemicals in hand I do wonder:1) Is there really any "right" way to set the tension on the drag wires? I'vetightened them to where I think they are "snug" but not so tight they twang.They are cables with turnbuckles. I have safetied everything off.Thanks, Bert ________________________________________________________________________________

Alex,Don't really know at the moment. My plans are up in the hanger. Maybe if youhave the prints there,,,I built right to the long fuselage prints supplied fromthe Pietenpol family, with the split gear from the supplied prints of 1933/34?No changes to the long fuse and gear. (using 24" O.D. tires)One old brain to another :)walt evansNX140DL ----- Original Message -----

Hey BertMy opinion is the wires should have a twang. Harmonics are good indication oftension. If you give them all the same sound your rig will be all equal.Dick ----- Original Message -----

Not too tight, though. I put an inspection hole to be able to adjust the turnbuckles, if needed. So far, after about 100 hrs, not needed. They also need something to prevent chafe where they touch in the middle of the 'X'. While we're on this subject, my drag / anti-drag cables touched a few of the ribs. I notched the stick for clearance, and added supporton the oposite side. Did this happen to any others ? The wing on Doug Bryant's plane was the same way.Chuck G.________________________________________________________________________________

Dale and I had some rib / wire interference. We did the same thing you did,notch the rib andadd a doubler.Greg Cardinal----- Original Message -----

Subject: Re: Pietenpol-List: Adjusting tension in drag/antidrag cables.On the rib/wire business, I also encountered the problem while building 41CC. This time I will leave my ribs unattached, install wires and fittings, bring up to tension,THEN move the ribs a skosh here and there for clearance before glueing, skrewing or nailing. I hope it works easier. Same difference just sorta working backwardsCorky in La/ with a new walking cane suffering HLS.________________________________________________________________________________

Subject: Re: Pietenpol-List: Adjusting tension in drag/antidrag cables.Good idea Corky, Which ribs are affected during the thighting of the cables? I have not started the ribs yet, but something to place in my notes to save time later.Greg MenocheDelaware________________________________________________________________________________

Subject: Re: Pietenpol-List: Adjusting tension in drag/antidrag cables.Greg,Go ahead and string your ribs on the spars and position according to plans. Small nail in each will hold until you find which ones to move. It's all so very slight and not enough to spoil that FC-10 airfoilCorky________________________________________________________________________________

My mentor is from the old school,,,whenever wires cross, he taught me to userib stitch cord,,,make about 4 turns around the "X", but not tight, now youchange direction and circle around between the two wires about 3 or 4 timesto make a "standoff" between the two cables. Winds up looking like a tighthangmans knot with two loops. Now if the slack was right in the beginning,when you pull the whole thing tight, It all goes tight. Tie it off with adouble knot, and a little varnish on the assy and you're done. It'sauthentic to the 20's.walt evansNX140DL----- Original Message -----
