DFX of a Patrol wing profile

~Does anyone have a DXF drawing of a Patrol wing profile. I have had Patrol plans # 238 for a while and am now ready to start making parts. I have a Knee mill with a CNC package. It is not very practical to use the mill to cut out each rib but it will work well for the rib form blocks. My email address is bwelfred@rogers.com
Thank you

Ed, If you still need a dxf file let me know. I traced drawing 4 and getting it laser cut in Portland now. Sent from my rotary phone
 
Hi Mark, my name is Alejandro and this would be my first post here!. I got Patrol plans #301 Would you share thos DFX files with me too?
 
Some day there will be a Bearhawk Bank, where DFX files of every part are deposited. Then one can retrieve a copy to use in there own shop, or have it on hand for there local fabricator.
 
If you can talk Bob into it from the IP perspective, I can make it happen from the technical perspective.
 
Hey Scott, I think so, but might only be rough outlines for purposes of laying out of a sheet for cutting. I'll check.
 
That would be great, thank you. I'm trying to get the hang of Solidworks and importing a jpg into a sketch. If you have the DXF I can resize it to match the drawings.
 
Scott I saw this in my inbox at work from Draftsight. This is a time saving feature to translate an image into a dwg. Before, I manually traced over the image using splines etc. I did have control of the precision, like staying on the inside of the line vs outside, but I would think this feature would be plenty useful for someone wanting to model parts of the Bearhawk.

I saw that video, I don't believe that addin is operational in the EAA version of the software. I am going to try this weekend. It certainly would be a time saver.

Before laser cutting any parts for your bird, you should investigate this process, Rans aircrafts went into chapter 11 because so many of their parts have been found defectives, apparently the heat
of the laser on the aluminium parts make them brittle and prone to cracking, you can find a lot of info online on the Rans forums.

Im not sure if this old thread is still monitored or not but I would also like to get a copy of the DXF files for the patrol wings to use with my upcoming build.

all of that seems like it would soak up a lot of time-- time that could be used to build parts. I felt like the wing master rib on the mylar was plenty accurate.
I feel like any error that there could be in that is less than my error downstream---
YOu may have a different opinion.
