Ok, Ernest. I figured you had taken care of the details, but never hurts to ask Ed Ed Anderson Rv-6A N494BW Rotary Powered Matthews, NC eanderson@carolina.rr.com http://www.andersonee.com http://www.dmack.net/mazda/index.html http://www.flyrotary.com/ http://members.cox.net/rogersda/rotary/configs.htm#N494BW http://www.rotaryaviation.com/Rotorhead%20Truth.htm -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Ernest Christley Sent: Thursday, August 06, 2009 2:57 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Actual rotary engine work...was Re: [FlyRotary] Re: T-shirt design Ed Anderson wrote: Ernest, I would highly recommend that if you are going to mount your radiator that way with the bolt touching the back of the core, that you sheath it in a thin abrasive resistant plastic/rubber tube. If it is touching one of your cross channel tube all the more so. You can barely see it at the far end of the radiator, but the all-thread is pushed through a piece of 3/8" nylon tube. I might switch it to a silicon tube in the future, but this is good enough for now. Better would be to move it out 1/4" or so away from the core. It started a 1/4" from the core. As the nuts are tightened to pull the ears to wrap around the core, it makes the rod bend and push the back of the radiator. Everything is locked into place. Nice job on the fiberglass duct, but you may find positive pressure inside the duct will leave the edges up off the metal. Also unless sealed inside, the core tank ridges will provide plenty of opportunity for those air molecules to evade going through the core. The black smudges at the top and bottom. Silicon sealant. I know that Tracy recommends red, but I had black on hand. Also, the way the duct is shaped, the upper lip is really stiff. (oh, no...here come the puns). The sides will need a few squirts of spray foam. It is such a small amount, that I won't do that until I need some for something else. -- Ernest Christley, President Ernest@TechnicalTakedown.com TechnicalTakedown, LLC www.TechnicalTakedown.com 101 Steep Bank Dr. Cary, NC 27518 (919) 741-9397 -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html __________ Information from ESET NOD32 Antivirus, version of virus signature database 3267 (20080714) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 3267 (20080714) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
