There is information available on the web for making your own springs. Do a Googlesearchfor "making springs" and you will come up with several tutorials. A quick glancethrough one showed winding music wire around a mandrel and then stress relieving it in a 500deg oven foran hour or so.http://home.earthlink.net/~bazillion/springs.html-Mike McCarty----- Original Message -----

I agree with Doug. Make up your own using 1/16 or 3/32 wire. 3 wraps around a 1" mandrel and make the ends however you like.Greg Cardinal> "DOUGLAS BLACKBURN" >> Not sure if it is want you want, see what > others say, but Piano wire that> you get in Hobby stores can be bent in many > configurations and maintain its> springy-ness...>> Doug Blackburn.>> >>>The body of the unit is no big deal, but I >>can't find a spring.>> Do any of you have any suggestions.

Subject: Re: Pietenpol-List: Hare and Turtle AirspeedCraig,A few months ago, I posted a detailed description, complete with all the measurements, of the Johnson Airspeed indicator. I thought I saved it on my computer, but I can't find it. I think if you would search the archives, you willfind it there.Chuck G.________________________________________________________________________________

The vane-type airspeed indicator in the picture is a DeHavilland type that was used on Gypsy Moths and Tiger Moths.Using one of these as a pattern, I made a copy for my Pietenpol years ago and marked the scale with reference to the ASI in the cockpit. I had difficulty matching the wire type and diameter and used drag/antidrag wire from a J-3 Cub wing to make the spring. It is not as hard as piano wire, but is sufficiently springy for the purpose. Since it was a bit stiffer (slightly larger diameter) than the wire on the DH "instrument", I had to make a larger vane to get enough travel over the scale. Marks (no numbers) were initially placed on the scale and the position of the pointer was noted during flight, using these marks for reference. Then the scale marking was done, complete with numbers similar to those in the photo.Today, it is mounted on the left front interplane strut of my Sperry Messenger replica and has proved to be a reliable device, always in close agreement with the ASI on the instrument panel.Cheers,Graham Hansen (Pietenpol CF-AUN in Alberta, Canada) ________________________________________________________________________________
