I am restoring my thirty year old clone, that I built after it was discontinued the first time. Can anyone tell me what the width of the sail is? The plans I downloaded did not have that info, just the lengths of the angled sides, peak, and overall length .

Did you download these plans?

http://www.spacemodeling.org/jimz/est1373.htm

There is a .tif file of the sail with dimensions on that page. Print the file to full size and you can measure the width. Or just use it as a template and cut out your sail.

Again does anyone know the measurement of the width as it is supposed to be. As measured from an original sail.

Okay, let's try this again.
PRINT the .tif file below
MEASURE the total length of the sail printout and divide into 24", the actual length. This is your scale factor
MEASURE the width of the sail printout
MULTIPLY that number by the scale factor

It comes out to exactly 3 inches. And I would wager you that if you are lucky enough to find someone with the actual kit, their measurement will be the same.

I'll have to look in my spare parts bin, I think I remember seeing one last year

I have a Soaring Eagle kit #1373 I will be selling soon.

Since that is your current restoration, I could set it aside for you.

The average selling price is a bit outrageous at $67.00 but I would be willing to accept (not except!) an offer.

scott_mills 09-27-2018 11:23 AM

I appreciate the offer sandman, go ahead and get a good profit for it. I really want to treat what I've already done like a rescue rocket. Plus I felt a sense of accomplishment having cloned it with nothing more than a xeroxed copy of the instruction sheet a protractor ruler and a few assumptions about sizes from those decades ago. Cloning today is much easier with friendly folks tracing fin patterns, scanning and posting them online for everyone else to enjoy.

To bar geezer yeah I could do it your way, waste the paper, and measure. I can also take the listed measurements and do a couple of minutes worth of geometry or trigonometry. I could also load the file up into an image editor, assume it's geometrically accurate, count the pixels , do some multiplication based on one of the known lengths, and have my answer. Or I could hope that someone on the forum was nice enough to just take a ruler out to there shelf bird and post the answer to the question that I asked. For which I would thank them.

Understood, no hard feelings. Just didn't want to see you waiting forever. This is a rare bird, and surviving ones are few and far between. Cheers.

I've got one I measure tonight.
