I picked up a used Pacific Scientific cable tensiometer on ebay for $100.These gor for like $800 new. It did not come with risers.I've never used one before and am wondering what number risers are used forwhich size of cable.Also where can I send it for calibration and where would I buy the risersfor it?Anyone have one of these?DJ VeghN74DVMesa, AZwww.imagedv.com/aircamper________________________________________________________________________________

Subject: Re: Pietenpol-List: Pacific Scientific T5 cable tensiometerDo you think you could get close enough by calibrating it yourself? If it's for use on your Piet, you could suspend a known weight from a piece of 3/32 cable, to produce a known tension in the cable. My problem is I don't know anything about the required tensions in the various cables in the Piet. I havejust finished my wing panels and I guessed at the tension......Any suggestions?....Carl V.________________________________________________________________________________

Subject: Re: Pietenpol-List: Pacific Scientific T5 cable tensiometerCarl,No intention to barge in a discussion: On the subject of cable tensions I asked for and received next to nil when I started to complete my wings soooooooo I turned buckles, measured, turned buckles, measured some more until I thought they were tight enough to hold thething in shape then I proceded to tune the cables as you would the strings on abull fiddle or a Fender. I used the same procedure for the cabanne cables as well as the wing strut cables. It equalizes the tension more accurately than could ever be done with a tool. Couldn't use the same technic on the tail feathercables as they are 1/16 and the pitch would be too high for my hearing range as my highs went with WWII.Try it, it might work for you.Corky________________________________________________________________________________

Boy, I didn't think THAT one out !! Guess I'll pull the "buttons" off and try your method.

Subject: Re: Pietenpol-List: Pacific Scientific T5 cable tensiometerThanks for your comments, Corky. That's about what I've done too. The tensions may not be right, but they're close to even...Carl________________________________________________________________________________

They are not available any more as I understand. I have attached theinstruction sheet which I transcribed from the factory original.Calibration is done by hanging a known weight on a cable and measuring tosee if the gage reads right. In the lid of the box is the conversion table.I can scan and get a copy to you if you need.Cy Galley, TC - Chair, Emergency Aircraft Repair, OshkoshEditor, EAA Safety Programscgalley(at)qcbc.org or experimenter(at)eaa.orgAlways looking for articles for the Experimenter----- Original Message -----
