I did not use any squeeze technique, just wet lay-up with West System. The tubes are just the right size for the SCAT ducting. These are now installed in the front of the cowl as part of the engine cooling ducts. http://websites.expercraft.com/sidwood/images/151628683049616756461fe.jpg http://websites.expercraft.com/sidwood/images/213718205496168855003f.jpg Sid Wood Tri-gear KR-2 N6242 Mechanicsville MD, USA smw...@md.metrocast.net >The second is a nifty way to make composite tubes and rods http://www.epoxyworks.com/26/pdf/Building_composite_tubes.pdf I have also seen it done inside a PVC tube with a bicycle inner tube as a bladder to force the lay-up onto the inside surface Paul Smith Brisbane, AUSTRALIA _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html No virus found in this incoming message.
