There has been a number of discussions on other threads about CAD files (DXF, DWG, etc.) for the ribs, plates and just about anything that can be produced with CNC machines.
Some of the discussions have referred to the 'Old Yahoo Group' having files listed for all things Bearhawk. I have a CNC router that I've used the Yahoo Group DXF files to test cut the center section and nose ribs, which worked fine. I am also building a larger CNC machine to handle 4 X 12 sheets of aircraft aluminum (and smaller) in order to make all the parts for my Bearhawk build as well as any other homebuilt aircraft that friends are building.
Interestingly enough, all those files are still posted at the 'Old Yahoo Group' and can be downloaded and saved. Not only the CAD files, but everything that had been posted over the years. I've downloaded just about everything from that group to my PC for future use.
The really cool (aviation term) and interesting files are the DXF files for the ribs and the spars, which include the spar plates, strut attach bar and more. They tell a lot and answer a lot of questions. I don't know who originally produced them, but the accuracy seems to be dead on. Any use of these files should be with caution and the builder obviously is responsible to verify the accuracy.
You'll need to sign in with your Yahoo Group particulars, and on the front page under the emotional inspiring photo of Pat Fagan's campsite, click the word 'Files'
Or just use this after you sign in.
All you'll need to view and manipulate these DXF files is a 2-D CAD Software. There is a great free software which is a fully functional 2-D CAD program that is amazingly close to AutoCAD.
It's 'DraftSight' by Dessault Systems. I've had the DraftSight for over two years and works great. Many of the same symbols and functions as AutoCAD. No time limit on it's use
