Re: [ULF-1] Ulf-1 Digest, Vol 57, Issue 4
Peter, We are doing a group build with EAA Chapter 309, Charlotte, NC. We started in 2012 and have all the tail surfaces built, tail boom of fuselage, bulkhead 1 and 2, seat box, forward fuselage sides, and now we are framing up the wing spars. We use a guy in our club who has a CNC machine. We get spruce and ply from Aircraft Spruce. We are a few years out from completion and are planning to power it with twin electric pusher motors.

I don't have a CNC machine but there may be some local firms that I could sub it out to. What did you use for cutting the Member 60 pieces?

We did loaded destruction tests on these ribs and compared them to the stick built ribs. Weights were comparable, but they were 3-4 times stronger than stick built ribs, plus much faster to build. So, we feel this is a more modern way to build all the ribs, but nearly as beautiful as Josef's ribs! >> >> We digitized all the loft drawing contours, and cut out all the ribs with a computer controlled CNC cutting machine with a round router cutting blade. We programmed the machine to cut 3/32" less top and bottom to allow for the thickness of the spruce cap strips. >> >> I will try to send some photos. >> >> Member 72 >> SN 383 E >> >> >> >> Sent from my iPad >> >>> On Sep 27, 2014, at 12:56 AM, Member 100 <[email]> wrote: >>> >>> Hello. I am new to the discussion group and I am considering a ULF-1 project. I have read many of the threads here and they inspire a few questions. What are most of the builders cutting out your parts with? CNC? Those that used the blue foam for the ribs, did it work and substantially cut down on build time? >>> >>> Best Regards, >>> Peter Member 100 >>> >>> >>> >>> >>> >>> >>> >>> >>> _______________________________________________ >>> ULF-1 discussion list -- [email] >>> >>> Subscribe, Unsubscribe, Preferences, List information: >>> http://lists.ulf-1.com/listinfo.cgi/ulf-1-ulf-1.com >> -------------- next part -------------- >> An HTML attachment was scrubbed... >> URL: <http://lists.ulf-1.com/private.cgi/ulf-1-ulf-1.com/attachments/[phone]/7a8f4ffa/attachment.html> >> >> ------------------------------ >> >> Subject: Digest Footer >> >> _______________________________________________ >> Ulf-1 mailing list >> [email] >> http://lists.ulf-1.com/listinfo.cgi/ulf-1-ulf-1.com >> >> >> ------------------------------ >> >> End of Ulf-1 Digest, Vol 57, Issue 4 >> ************************************ > _______________________________________________ > ULF-1 discussion list -- [email] > > Subscribe, Unsubscribe, Preferences, List information: > http://lists.ulf-1.com/listinfo.cgi/ulf-1-ulf-1.com
